Simone Biles provided further inspiration when she returned to action on Tuesday and secured a bronze medal on the balance beam.

China enjoyed success with a Guan Chenchen and Tang Xijing one-two, but the American gymnast stole the headlines on her first appearance back after withdrawing from the team final last week.

Mental health concerns were cited as the reason for Biles stepping away from the team events and other individual disciplines, though the 24-year-old excelled in her sole event on the beam.

The four-time Rio Olympics gold medallist reminded the world of her quality with a 14.000 score, and, despite Chenchen's last-ditch 14.633, she produced an emphatic return for the United States.

"I was just happy to be able to perform, regardless of the outcome," Biles explained after Tuesday's event. "I did it for me, and I was just proud of myself for being able to compete one more time.

"Just to have the opportunity to compete at the Olympic Games meant the world, because training for five years and then coming here, then kind of being triggered and not being able to do anything, it wasn't fun.

"To go out there and compete one more time and have everyone's support meant the world."

To add to Biles' memorable comeback, the USA's basketball stars nudged past Spain 95-81 to reach the Olympic semi-finals, with Kevin Durrant netting a team-high 29 points to drive his side towards victory.

It was a far from convincing performance from the USA, however, as they trailed 39-25 at one point in the second quarter before rallying impressively to level at 43-43 at the halfway stage.

THOMPSON-HERAH COMPLETES DOUBLE-DOUBLE

Elaine Thompson-Herah motored to sprinting history as she won the 200 metres women's final to complete the sprint double-double.

The Jamaican set a new national record with 21.53 seconds, the second-fastest time in the history of the event, making herself just the second athlete ever, after Usain Bolt, to win both titles at consecutive Games.

Thompson-Herah, who claimed 100-metre gold on Saturday after doubling up for the first time at Rio 2016, just missed out on Florence Griffith-Joyner's 1988 world record by 0.19s.

"Oh my god, it's amazing that I have ever seen this day. That I could complete another double. I can't believe it," the 29-year-old said after the 200 metres final.

"I really had to pull it out to win the 200m. It's a new PB [personal best] and a national record. I am so, so happy.

"Honestly I am so tired, my legs just need some rest. I've done so many races in the last few days, but I am very grateful."

WARHOLM'S WORLD

Karsten Warholm demolished the world record with a remarkable 400 metres hurdles triumph, smashing the previous record run for a second time in five weeks.

At the start of July in Oslo, Warholm cut 0.08 seconds off Kevin Young's longstanding record that was set at the Barcelona Games in 1992, though the 25-year-old slashed even more off in Tuesday's final.

The Norwegian star powered through in 45.94s, hacking an astounding 0.76s off the global mark to secure a memorable victory.

"It's just so big. It's almost like history here. It was the only thing missing from my collection," the 25-year-old said after his win. "I had a World Championships [gold medal]. I had European Championships, I had the world record, the European record.

"The Olympic gold medal is what everybody talks about. I knew this race was going to be the toughest of my life, but I was ready."

The top three finishers all beat the previous Olympic record, with American silver medallist Rai Benjamin running 46.17, yet the performance of Benjamin's life was simply no match for Warholm.

BRAZIL PREPARE TO DEFEND TITLE

Brazil inflicted shoot-out heartbreak on Mexico after a 0-0 stalemate in 120 minutes to set up a final showpiece with Spain.

Reinier converted the crucial spot-kick and, with Eduardo Aguirre and Johan Vasquez missing, the defending Olympic champions ran out 4-1 victors.

"Playing the final match in the Olympics is a dream," said Brazil's head coach Andre Jardine. "The film I saw was the film of life. Everything we’ve gone through. Although we didn’t win in the 90 minutes, we took more risks."

Japan suffered extra-time agony in their semi-final against Spain as Marco Asensio's late winner sunk the host nation to tee up a mouth-watering prospect for Saturday's final.

Despite footballing disappointment, women's boxer Sena Irie provided the host nation reason to celebrate as she edged past the Philippines' 2019 world champion Nesthy Petecio to achieve gold.

Irie's win in the women’s featherweight class final means she is Japan’s first female boxing champion at the Olympics.

CYCLING CHAOS

Germany twice recorded world record rides to earn their first gold – and, in fact, their first ever medal – in the women's team pursuit cycling track event.

A strong Great Britain side, including Laura Kenny, awaited Germany in the final but the team of Mieke Kroeger, Franziska Brausse, Lisa Brennauer and Lisa Klein produced the ride of their lives to finish in 4:06.159, almost two seconds quicker than the previous record.

In a dramatic day of cycling, the reigning world champions Netherlands won their first gold since 1936 in the men's team sprint as Team GB again had to settle for silver inside the velodrome.

That silver for Jason Kenny meant he became the first athlete to win eight Olympic medals in cycling track events and also equalled the total medal haul of Britain's most successful Olympian Sir Bradley Wiggins.

More controversy filled Tuesday's track events, with Denmark's Frederik Madsen crashing into the back of Team GB's Charlie Tanfield inside the closing kilometre of the men's team pursuit heats.

The UCI later deemed the Danes, who were near two seconds ahead of their opponents, to have completed a successful catch to make it through to Thursday's final against Italy, despite the incident.

Kevin Durant said Team USA have "got to finish it" after battling past Spain to reach the Olympic semi-finals.

The Brooklyn Nets star poured in a team-high 29 points as the United States won 95-81 at the Saitama Super Arena, bolstering their gold medal hopes.

It was far from an easy assignment, and nor was it always entirely convincing from the US team, who trailed 39-29 with 3:25 of the second quarter remaining.

They rallied impressively, however, to draw level at 43-43 at the halfway point, and Spain never led again.

"We started making shots there in the second quarter. Once we see that ball going into the rim, that put all of us at ease," Durant said.

"Our defence was a little better, a little tighter, we rebounded better after that. And guys just got more comfortable shooting the basketball.

"We drove it to the rim at the end of that second and were able to get our rhythm back a little bit. I like how we played in that second quarter, from the end of the second quarter all the way to finish the game, and that's how we're gonna need to play going forward.

"It was a huge boost. We didn't want to go into the half down double digits. We knew we didn't want to get down big against this team."

Ricky Rubio plundered 38 points for Spain, with the Minnesota Timberwolves man shooting 13-of-20 from the field. That gave him the highest score by a Spain men's player in an Olympic game, beating the 37 points that Pau Gasol scored against China in 2004.

Rubio also drained four of his seven shots from three-point range, the same as Durant, but USA's 22-6 run at the start of the third quarter took the game away from Spain.

The Spaniards briefly got back to just four points behind, in the early moments of the fourth quarter, yet despite their overall 42-32 dominance on the boards, they were found wanting elsewhere.

USA coach Gregg Popovich said: "I feel great about the victory knowing full well there is a lot of work to be done. We played a terrific basketball team.

"To play that team and go down by nine or 10 and stay in and find a way to win is very satisfying."

Durant feels the team are ready to step up a level, now they are through to the final four.

The pre-Olympics defeats to Australia and Nigeria no longer matter, nor does the loss to France in the Tokyo 2020 group stage.

"I love how we stuck with it throughout this whole period of time and guys started figuring out what we need to do," Durant said.

"You've just got to finish it. We're supposed to be here. For us it's about getting a gold."

Norway's Karsten Warholm smashed the world record in the men's Olympic 400 metres hurdles final, breaking the 46-second barrier on the way to gold medal glory.

Warholm finished in 45.94 seconds, well ahead of his own previous record mark of 46.70. USA's Rai Benjamin claimed silver in 46.17, also beating the old world record, with Alison dos Santos taking bronze in 46.72.

"It's by far the biggest moment of my life," Warholm said. "It defines everything, all the hours I put in, everything that my coach has been working for.

"With all the respect for all the athletes, there are athletes that were not good that will get an Olympic gold. Rai running 46.17 would deserve a gold medal. It is crazy, it is just an honour to be a part of it. I never thought in my wildest imagination that this would be possible."

Asked about his dash to the line in the closing metres, Warholm added: "I couldn't even feel my legs. I knew I had a crazy American trying to catch me, so I ran for my life."

Germany's Malaika Mihambo admitted she could not watch the finale to the women's long jump as she won gold.

Mihambo took the lead with a jump of 7.00m with her final attempt before USA's Brittney Reese and Nigeria's Ese Brume had their last jumps.

Neither could better the leading mark, with Reese settling for silver with 6.97 metres on countback ahead of Brume.

"It was really hard to watch, so I tried to just have a sneak peek on the display and see how far it was," Mihambo said.

"I really don't like this position where you cannot do anything about it, and you just have to let the girls do what they're able to do. You have to wait, so it was a horrible moment, but at least it was short.

“I feel overwhelmed. It was, I think, the most exciting women’s long jump competition in history."

DURANT DOMINATES AS USA SURVIVE SCARE

The United States did not have it all their way but triumphed 95-81 over Spain to seal a spot in the men's basketball semi-finals.

Spain led by as much as 10 points in the second quarter before USA drew level by half-time and accelerated in the second half. Spain again closed within four points of the gold medal favourites in the final quarter, inspired by Ricky Rubio's 38 points.

Kevin Durant excelled for Team USA, with 29 points and four assists, while Jrue Holiday contributed 12 points and five assists as they capitalised on a 17-9 turnover differential.

USA lost to Australia and Nigeria in exhibition games prior to Tokyo 2020 before losing their Olympics opener to France but have since steadied.

The winner of Australia-Argentina will play USA in the semi-finals on Thursday.

NBA duo Zoran Dragic (27 points, six rebounds and four assists) and Luka Doncic (20 points, eight rebounds and 11 assists) starred as Slovenia also progressed to the semi-finals with a 94-70 win over Germany.

CARRINGTON'S GOLD KAYAKING DOUBLE

New Zealand's Lisa Carrington had a golden day in the kayaking, remarkably winning two gold medals within an hour.

Carrington won her third straight gold in the women's kayak single 200m with an Olympic best time of 38.12 seconds, ahead of Spain's Teresa Portela and Denmark's Emma Jorgensen.

The New Zealander backed up alongside Caitlin Regal to win the women's kayak double 500m final with a world best time of 1:35.785.

Carrington joined fellow kayakers Ian Ferguson and Paul MacDonald and equestrian great Sir Mark Todd as the only New Zealanders to have won five medals at the Olympic Games.

The 32-year-old may win more medals too, competing in the K1 500 event which starts on Wednesday.

“Today was about taking just one race at a time," Carrington said. "There's a plan, and it was just about executing it. For me, it was just trying to stay in the moment and doing the best I can. We've worked really hard and knew today was going to be a big day.”

HENDRICKX POWERS BELGIUM INTO HOCKEY FINAL

World champions Belgium qualified for the gold medal match of the men's hockey after a commanding final quarter sealed a 5-2 win over India.

Belgium piled on three fourth-quarter goals to guarantee a medal in the decider where they will face either Australia or Germany.

Alexander Hendrickx scored a hat-trick including two of the Red Lions' goals in the final quarter after India had fought back from an early deficit to lead 2-1 at quarter-time.

Drag flick expert Hendrickx has scored an unrivalled 14 goals during Belgium's Tokyo 2020 campaign, eight clear of the next best, Australia's Blake Govers.

Hendrickx said: "It's really a team job that comes together. It's my name on the scoresheet, but it's a team job."

World number one Australia and sixth-ranked Germany meet later on Tuesday to determine the other gold medal match finalist.

Kyle Lowry is set to leave the Toronto Raptors to join the Miami Heat after the 35-year-old point guard revealed the free agency move on social media.

The six-time NBA All-Star, who has been with the Raptors since 2012, will reportedly join the Heat on a three-year deal. The deal marks the start of the NBA free agency period.

Lowry announced the deal on Twitter, posting "Miami Heat x Kyle Lowry Let's goo!!"

ESPN claims the deal is worth approximately $90 million, completing via a sign-and-trade with the Raptors.

Lowry holds records for most assists, most three-point field goals and three-point attempts for Raptors and is widely viewed as the best player in franchise history. He was part of the Toronto side which won the 2019 NBA title.

The veteran played in 601 games after joining Toronto in July 2012, behind only DeMar DeRozan (675) on their all-time list. 

Lowry averaged 17.2 points, 5.4 rebounds and 7.3 assists per game in the 2020-21 NBA season.

The Heat reached the NBA postseason in 2020-21 but fell in the first round 4-0 to eventual champions, the Milwaukee Bucks.

The United States are showing no complacency despite maintaining a sensational streak en route to a last-eight clash with 2018 FIBA Women's Basketball World Cup final opponents Australia at the 2020 Olympics.

Team USA are the clear favourites for the women's basketball title after extending their winning run at the Games to 52 matches, going back to 1992.

They could tie the record of seven consecutive gold medals in a team event – set by the men's basketball team between 1936 and 1968 – by triumphing again in Tokyo.

But the United States survived a scare in their final Group B outing on Monday.

France, needing merely to lose by 14 points or fewer to advance, led with under nine minutes of the fourth quarter remaining before going down 93-82 – 11 points being Team USA's largest lead.

Sue Bird, aiming alongside Diana Taurasi to become the first athlete to win five Olympic golds in team sports, feels her team must heed their warning.

"There are a lot of areas that we need to improve on in the next 48 hours, I guess," she said, with Australia later confirmed as the United States' last-eight opponents.

"I said this the other day: these teams in the Olympics, these teams have trained and they have waited four years and they play like it is their last game.

"It is a desperation that we have not risen to just yet and we need to get there quick."

'A WORK IN PROGRESS'

Team USA had 22 points on nine-for-12 shooting and seven rebounds from A'ja Wilson and 17 points, seven rebounds and seven assists from Breanna Stewart, who played 38 minutes, but coach Dawn Staley agreed with Bird's assessment.

"[France] played with extra effort, they hit some incredible shots and they put us back on our heels," Staley said.

"I thought we made some adjustments and I thought we did what we needed to do to win a basketball game.

"We had great contributions from a lot of different people, but we're still a work in progress and hopefully we can continue to clean up some things and some areas out on the floor."

Stewart will have fond memories of facing Australia after the 73-56 final win at the World Cup, where she was named MVP.

After beating France, she said: "This is where we start to peak."

OPALS LEAVE IT LATE

Australia had a tough task in reaching the last eight. They needed to beat Puerto Rico by 25 or more points to pip Canada to the last quarter-final spot.

The Opals entered the final two minutes 19 points ahead, but five from Leilani Mitchell in the closing stages – boosting her tally to 19 – helped secure a precious 96-69 success.

Australia have already taken on one of the top teams in China, who ended the preliminary stage as the first seeds after a 74-62 success against Belgium. They face Serbia next.

FRANCE PUT UP A FIGHT

Meanwhile, a quarter-final against Spain was the consolation in defeat for France, whose desire impressed Staley.

"The countries here at the Olympic Games, they pour into their women's teams, and now you're seeing the effects of it," the United States coach said. "And that is great women's basketball play.

"We know we're in a dogfight every time we step on the floor.

"It's great for those who just put the television on and sit down and watch players that they haven't seen before, countries that they haven't seen before, and see them play a great game."

France's Nevada-born forward Gabby Williams added: "It was 10 minutes by 10 minutes and [we were] just trying to focus on staying with them."

In the same pool, Japan – led by Saki Hayashi's 23 points and seven made threes, along with Rui Machida's record-equalling 15 assists – beat Nigeria 102-83 and will face Belgium next in the quarters.

Long jump favourite Juan Miguel Echevarria was left in despair after injury prevented him from chasing the gold won by Miltiadis Tentoglou on countback at Tokyo 2020 on Monday.

Tentoglou said he was lucky to win gold in a shock result over Echevarria with a last-ditch sixth-round leap of 8.41m, beating Echevarria on countback, while Cuba also claimed bronze thanks to Maykel Masso's jump of 8.21m.

Echevarria, who had topped qualifying, had a final chance to beat the mark with his sixth attempt but could not make the jump due to injury, slumping to the floor on his knees in despair, consoled by compatriot Masso.

"It was very, very painful. I couldn't do what I usually do," Echevarria said.

"I have no words to express how I feel because I couldn't achieve what I wanted, what I have been fighting for so many years.

"I am personally not very happy with the result. I have always tried to go further."

The Greek had earlier registered a second-best jump of 8.15m compared to Echevarria's 8.09m to have the countback advantage, with his final attempt putting him ahead.

"Last attempt, I told myself to calm down and do a normal jump. I didn't expect it could be so big," Tentoglou said.

"I consider myself lucky. I was not lucky to jump 8.41m the last attempt but I was lucky to win."

The winning distance of 8.41m was well short of Mike Powell's world record of 8.95m, which has stood since 1991.

Tentoglou backed Echevarria to move on from his Olympic disappointment and one day reach the milestone.

"If someone can do the world record, it's Juan Miguel," he said. "I don't know for me. I need to do the national record first. I am not the national record holder."

Puerto Rico's Jasmine Camacho-Quinn triumphed in the women's 100m hurdles a day after setting a new Olympic record in the semi-finals.

Camacho-Quinn won in 12.37 ahead of USA's Kendra Harrison (12.52) and Jamaica's Megan Tapper (12.55), who had an anxious wait to find out if she had claimed bronze ahead of Nigeria's Tobi Amusan (12.6) in fourth.

The Puerto Rican admitted afterwards she had her sights set on Harrison's world record of 12.2 but clipped a hurdle to thwart her.

TEAM USA AVOID BASKETBALL SHOCK

The United States bounced back after trailing to France in the last quarter to record a 93-82 win in the women's basketball.

France had headed the US 72-71 in the fourth quarter, but the gold medal favourites rallied with a 7-0 run to assert their dominance.

A'ja Wilson was huge in the final quarter, finishing with a game-high 22 points, along with seven rebounds and three assists, while Breanna Stewart had 17 points, seven rebounds and seven assists.

Japan booked their quarter-final spot with a 102-83 win over Nigeria, while the US will go through in top spot from Group B ahead of the quarter-finals.

HOCKEYROOS HEARTBREAK, INDIAN JOY

Australia's Hockeyroos had a perfect group phase with five wins from as many games but were stunned by India in the quarter-finals 1-0 in women's hockey.

Gurjit Kaur scored the winner from a 22nd-minute penalty corner to stun the Australians, who have not medalled in women's hockey since Sydney 2000.

Australia also lost in the quarter-finals at Rio 2016 but were far better placed in Tokyo after their exceptional group form.

India have never claimed an Olympic medal in women's hockey, finishing fourth in 1980, and will face world number five Argentina in the semi-finals.

Argentina, who have won medals at four of the past five Olympics, overcame Germany 3-0 aided by two goals late in the first half.

INDONESIA WINS FIRST TOKYO GOLD

Indonesia won its first gold medal of Tokyo 2020 as Greysia Polii and Rahayu Apriyani combined to triumph in the women's badminton doubles.

The Indonesian pair defeated China's Chen Qing Chen and Jia Yi Fan 2-0, in a triumph that was the country's first in women's doubles, having won all other badminton events.

Kim So-yeong and Kong Hee-yong won the all-South Korean bronze medal match against Lee So-hee and Shin Seung-chan 2-0.

Chris Paul and Kawhi Leonard are expected to decline player options for next season ahead of the NBA free agency period opening on Monday, but the veteran stars may stay with their teams.

After leading the Phoenix Suns to the NBA Finals, Paul will not exercise his $44million option for the 2021-22 season, The Athletic reported. ESPN added that the Suns are optimistic they will be able to re-sign the 36-year-old. 

Yahoo Sports first reported Leonard would decline his $36m option with the Los Angeles Clippers and become an unrestricted free agent, but ESPN reports he is expected to remain with the Clippers on a new deal after suffering a season-ending knee injury during the playoffs. 

Even if they end up staying where they are, those two will be the two biggest names on the open market beginning on Monday, but others figure to be available in trades. 

Kyle Lowry of the Toronto Raptors may top that list as he is expected to move on from Toronto. ESPN reported that the Miami Heat's move to pick up Goran Dragic's $19.4m team option might have been designed to facilitate a sign-and-trade deal for Lowry. 

Ben Simmons also could be on the move from the Philadelphia 76ers, but Bradley Beal now seems set to stay with the Washington Wizards after they sent Russell Westbrook to the Los Angeles Lakers in a draft-night trade. 

Argentina coach Sergio Hernandez heaped praise on Luis Scola after a crucial 97-77 victory over Japan that made sure of a place in the knockout rounds of the men's basketball tournament.

Following back-to-back defeats, Argentina needed to beat the hosts in their final Group C match to qualify for the quarter-finals as one of the best third-placed teams.

Scola certainly led by example. The veteran power forward scored 23 points and also had 10 rebounds as the 2004 Olympic champions prevailed, securing a last-eight date with Australia.

Still going strong at the age of 41, the five-time Olympian's efforts delighted Hernandez.

"He's ridiculous. He's a hard worker, he doesn't stop ever. I think he hasn't stopped one day in the last 25 years," the Argentina coach said. 

"I am sure I am not the same coach without him. Not for his 23 points [against Japan], but for his leadership. I love him."

Kevin Durant believes Jayson Tatum will eventually claim the Team USA points record he just took from Carmelo Anthony.

In scoring 23 points in the United States' 119-84 win over the Czech Republic – a victory that secured their progression to the quarter-finals at Tokyo 2020 – Durant reached 354 in Olympic play.

He is now past Anthony (336) and will expect to stretch his advantage in pursuit of a third Games gold.

The three-pointer that took Durant to new heights gave Team USA their first lead midway through the second quarter, with the Brooklyn Nets forward leading his country's recovery from a slow start.

Tatum took control thereafter, though, finishing on a game-high 27 points.

The 23-year-old is appearing at his first Games but has 50 points through three appearances, prompting Durant to make a bold claim.

Appearing alongside Tatum in a post-game interview, Durant said: "This guy to the left, I think he's going to be the next one to break that record."

Tatum boosted his total with five-for-10 three-point shooting, as the United States made 20 shots from deep – tied for their third-most in an Olympic game.

Coach Gregg Popovich said of Tatum: "Obviously he's more confident but he makes better choices, decision-making wise.

"He attacks for himself and for a team-mate at the same time, and he didn't do that in the very beginning in the league; he was just a scorer.

"But now he's valuable because he does the other things. He's starting to rebound better. We're telling him that it's important, we're not that big and we do need him on the boards."

In the same news conference, Durant was asked again about his achievement in surpassing Anthony.

"You just think about all the players that played in this programme and [it is] pretty cool to be among names like that," he said.

"Carmelo is a guy that I played on two Olympic teams with and I've seen his approach to these games and I try to steal some of his techniques and approach.

"It's still pretty weird for me to do stuff like this because I play a team sport and I try my hardest to make it about the group.

"But it is special to do something like that and scoring is something that I've worked on my whole career and something that I've expanded my whole career, and to consistently do it is pretty cool."

The Czech Republic were no match for the United States as Jayson Tatum and Kevin Durant starred in a 119-84 romp.

Team USA's emphatic victory sealed their place in the quarter-finals as the second-placed side in Group A and ensured they will not face one of the pool winners.

Durant put up 23 points and six assists, overturning an early deficit, while Tatum led the team with 27 points, including five three-pointers.

Team USA's 20 threes represented the fourth time they have managed as many in an Olympic game,  also doing so against Argentina in 2012 (20), Lithuania in 2004 (21) and Nigeria in 2012 (29).

Due to the margin of defeat, the Czechs – who threatened an upset before falling away dramatically – will not progress into the next round as one of the best third-placed sides.

ROTATION GAME

France were able to rest some star names as they progressed. Les Bleus had won their opening two games and completed a clean sweep in Group A with a 79-62 victory over Iran.

Only one player – Timothe Luwawu Cabarrot – played more than 20 minutes, with star men Evan Fournier and Rudy Gobert given limited game time.

Nando De Colo enjoyed a highly efficient cameo in his 15 minutes on court, scoring 10 points on 100 per cent shooting while adding five rebounds and five assists.

Iran talisman Hamed Haddadi finished off his Olympic campaign with an 18-point showing, but it was not enough to keep his team in the tournament.

France have already beaten the United States, but Fournier dismissed the suggestion they are gold medal favourites.

"To be honest, I'm not even focused on the gold medal, just the quarter-finals," he said. "Any team that we are going to play there will have its strengths and weaknesses, but I can't tell you who I would prefer there because we don't even know who's going to be there."

AUSTRALIA CLAIM TOP SPOT

Patty Mills scored five threes in a haul of 24 points as he led Australia to an 89-76 victory over Germany.

The Boomers needed victory to secure first place in Group B and they did so with a 13-point margin to ensure they will be seeded in the quarter-final draw on Sunday.

Despite defeat, Germany will go through as one of the best third-placed teams.

Mills is heading into unrestricted free agency in the NBA, but his sole focus is on propelling Australia towards a medal.

"This is a lifetime of work in a matter of a couple of weeks. I'm making sure there are no distractions for me or my team-mates," he said.

MANNION SEALS FOURTH-QUARTER FIGHTBACK

Italy clinched a spot in the last eight by overturning an eight-point deficit at the start of the fourth quarter to beat Nigeria 80-71 in Group B.

Nico Mannion scored 14 points in 16 minutes, including a vital late effort from deep to help seal Italy's comeback success as Nigeria ended winless following a 24-8 fourth quarter.

"I think everybody is surprised with the way he's playing, he's showing everybody that he's a great player. Also, he's only 20 years old," Achille Polonara said of Golden State Warriors guard Mannion.

"I hope that he can help us like this in the next game, too. He's a great guy, he's very happy to stay with us, and we're very happy to have him."

A decade ago, the Dallas Mavericks stood atop the basketball world after Dirk Nowitzki, Jason Terry and company won the NBA Finals over a heavily favoured Miami Heat team that featured LeBron James, Dwyane Wade and Chris Bosh in their first season together.

With the Heat dynasty clearly on the rise and with the Mavs fielding a veteran roster already, Dallas decided not to make an earnest title defense and traded defensive anchor Tyson Chandler.

The Mavericks have yet to win a playoff series since those 2011 NBA Finals.

Despite postseason appearances in six of the past 10 seasons and the acquisition of a generational talent in Luka Doncic, owner Mark Cuban decided change needed to come in the 2021 offseason.

Gone is Donnie Nelson, who had been the general manager since 2002 and was the architect of that title team a decade ago.

Also gone is longtime head coach Rick Carlisle, who had been in place since 2008 and amassed a record of 555-478. Nonetheless, Cuban decided to change things up.

"The league has changed in the 21 years since I've been here," Cuban said. "Players have changed. How you build a championship team has changed. Sometimes you just have to look to have a different tool set."

Who is in charge?

Doncic and Nelson have a famously close relationship and the 22-year-old star was disappointed to see his longtime friend replaced by former Nike executive Nico Harrison as general manager.

While training with Slovenia in preparation for the Olympic Games, Doncic admitted he was less than thrilled by the move:  "It was kind of tough to me. I really like Donnie. I know him since I was a kid and he was the one that drafted me.

"It was tough for me seeing that, but I'm not the one making decisions there."

This indicates that Cuban, who has long held the reputation as one of the most involved owners in American sports, was asserting his view of what the Mavs' leadership team should look like.

Yet moving on from Carlisle, long considered a leading NBA coach, appears to be a move targeted at appeasing Doncic. The young star had openly shown his disapproval with some of Carlisle's coaching decisions and substitution patterns, becoming increasingly prone to on-court displays of frustration.

Doncic may not quite wield the sway of someone like LeBron James, who has become the face of the "player empowerment era" in the NBA, but Cuban has wisely taken Doncic's input into consideration.

And as much as the hiring of a new leadership team represents a new era for the Mavs, Cuban is clearly trying to revive some of the magic of the 2011 squad.

Jason Kidd was named the team's next head coach, with it also announced that Dirk Nowitzki would begin a formal role as a front office advisor – two moves that also surround Doncic with mentors to help him progress into a champion.

The cornerstone

Doncic's career is off to an unprecedented start, and Dallas clearly intends to build around its multi-talented superstar well into the future. Doncic was the fastest in NBA history to reach 5,000 points, 1,500 rebounds and 1,500 assists, hitting those marks in 195 career games.

LeBron James took 228 games to reach those numbers. Michael Jordan needed 282 games.

Doncic has also improved every season since entering the league in 2018. Already a triple-double machine, he posted career-high efficiency in 2020-21 by shooting 47.9 per cent from the floor and 35.0 per cent from three-point range.

His game has started to mature, as well, especially as a scorer. Doncic is a child of the shot-efficiency era, and he has always gotten shots from the most efficient areas on the floor – at the rim, behind the 3-point line and at the free throw line. Those shots remain valuable, but Doncic has diversified arsenal of mid-range options by developing a variety of floaters and pull-ups. He shot 51.5 per cent from mid-range last season – better than mid-range maestro Devin Booker (51.2 per cent) – after shooting around 41 per cent in his first two seasons.

This bodes well as an indicator of future success in the postseason, when opponents' defenses are geared toward taking away the most efficient shots.

Doncic's numbers are virtually unassailable and make him almost a lock to win an MVP – if not more – at some point in his career. It can be hard to forget, though, that Doncic has only played three years in the NBA.

Giannis Antetokounmpo, although a less refined prospect when drafted, needed until his sixth season to win his first MVP and became a champion in his eighth season only after suffering heart-breaking losses, sanding away some rough edges in his game that made him vulnerable in the playoffs and evolving into a true leader.

Doncic's numbers may remain steadily impressive over the coming years, but he can still grow and develop in subtle ways as he matures. Kidd, a dynamic triple-double threat in his own playing days, will be responsible for overseeing Doncic’s growth.

"My job is to give him answers to the test," Kidd said of Doncic. "His imagination is at the highest level, which is a great thing to be a part of. I (as a young player) tried a lot of things, and I know I drove a lot of my coaches crazy. I won't get mad because I've been in those shoes."

Do the pieces fit?

With a .362 usage rate last season, Doncic shouldered the largest offensive burden of any player in the league. Kidd has already said publicly that the superstar will need more help from his team-mates going forward.

"Not having to bring the ball up every time and start the play," Kidd said. "When you look at the fourth quarter, he wears down at times."

Further evidence that Doncic will need more help is that he has exploded for more than 40 points in five of his 13 career playoff games, yet the Mavericks are just 2-3 in those games.

Kristaps Porzingis has been tabbed as the second option in Dallas but could end up in trade rumours sooner rather than later after a flaccid playoff performance, averaging just 13.1 points and 5.4 rebounds per game.

Despite largely considered a disappointment for not recapturing his peak form, Porzingis still plays an important role as a floor spacer on offense while defending bigger players. And while his numbers fall short of what is expected of a second option, his presence on the court makes Doncic better.

Porzingis spaces the floor and gives Doncic room to penetrate opposing defenses, allowing him to be more efficient while both scoring and assisting, while also shooting much better from any range with Porzingis on the court compared to when he sits.

Dallas' depth got worse last offseason with a disastrous trade that sent Seth Curry to the Philadelphia 76ers for Josh Richardson, who has failed to live up to his reputation as a defender and who is yet to match his 17-4-4 averages from his breakout season with Miami in 2018-19.

After a disappointing regular season, Richardson played just 13.4 minutes per game in the Mavs' first-round loss to the Los Angeles Clippers, averaging 4.9 points and shooting under 40 percent.

Curry, meanwhile, exploded in the postseason for Philadelphia, averaging 18.8 points and connecting on over half of his three-pointers on 6.8 attempts per game.

Richardson's defensive prowess also appears to be a farse, as the Mavericks allowed 113.0 points per 100 possessions with him on the court last season and only 107.7 with him on the bench.

Richardson appears to be a failed experiment, and Dallas will need to look elsewhere to find something resembling a third star.

Evolution or Revolution? Verdict: Evolution

The organisation has already undergone a massive transformation by ousting their longtime general manager and head coach in favour of a new direction, so it is fair to say that anything resembling a "revolution" has already taken place in the front office.

The Mavs' roster is far from a finished product, however, and Harrison will need to hit the ground running in his first general manager job. Dallas did not own the rights to any of its picks in the NBA draft, so he will have already assessed the need to look elsewhere to upgrade the roster around his young superstar.

The postseason failures and frequent injuries of Porzingis could lead the Mavs to the trade market, but opposing teams have also seen those weaknesses and have adjusted their assessments of him as well. Dallas may be better served by displaying some patience with a player who is still only 25 and has averaged over 20 points per game in three straight campaigns.

Milwaukee's 2021 title demonstrated that teams can still build patiently while developing players and Dallas may be one acquisition away – as the Bucks were with Jrue Holiday – from becoming contenders once again.

A'Ja Wilson led the way for the United States as they saw off host nation Japan 86-69 at the Tokyo Olympics, while China and Belgium booked their places in the quarter-finals.

Team USA are six-time defending champions, though they were made to work by their opponents in Saitama before their height proved decisive.

Now on a 51-game winning streak at the Olympics, Team USA top Group B on four points from their two games so far at the Games.

Wilson was the top scorer with 20 points, while she also contributed 10 rebounds and three assists. Support arrived from Breanna Stewart (15 points) and Brittney Griner (15 points).

It was by no means a comfortable victory, however, having edged out Nigeria 81-72 in their first match.

"Just communication. One, we're getting used to the ball. And then two, just working on making sure we're just all in for each other and understanding the personnel a little bit better," explained guard Jewell Loyd when asked how the team were looking to improve as the tournament goes on.

"Taking a breath. We've played a little fast in other games so just trying to get a rhythm for us, take it slow and play our basketball."

Only Wilson scored more points than Japan's Maki Takada, but the hosts were simply physically outmatched.

"[Team USA] are really superstars," said Evelyn Mawuli. "They know how to play and they're tall and we're small, so we have to run faster than them. So that was a bit difficult, but it was fun."

CHINA SNATCH LATE WIN TO SEAL QUARTER-FINAL SPOT

China and Belgium are sure of their places in the last eight.

That is because of a last-gasp win for China against Australia, avoiding overtime in dramatic fashion to clinch a 76-74 triumph in Group C.

China, who were led by 20-point Wang Siyu, were 11 ahead at one stage in the final quarter, but that deficit was cut down by a resurgent Australia.

However, with 0.6 seconds left, Li Yueru was fouled under the basket. She made both free throws to seal victory and progression into the quarters.

In the process, Belgium's progress was also secured. They beat Puerto Rico 87-52 in the first of Friday's matches.

GARNIER PROUD OF FRANCE REACTION

Elsewhere, France bounced back from an opening defeat to Japan with an 87-62 victory over Nigeria in Group B.

Five players made into double figures for points for the French team, with Sandrine Gruda topping the charts with 14, adding nine rebounds and three assists.

"It was necessary after the defeat against Japan to have a good reaction. I am proud of my team because they did and they all played very hard defence," France coach Valerie Garnier said.

"This is necessary against Nigeria because they fight a lot. After we did this very good job, we tried to make the biggest gap possible, so 25 points was a good result for us."

There were no excuses for Nigeria coach Otis Hughley Jr, who said: "We just got beaten really bad. Offensively we were flat and we couldn't score. You can't play that way against the number five team in the world."

Russell Westbrook is preparing for life on a fourth different team in as many years, with LeBron James welcoming his new running mate to the Los Angeles Lakers following a blockbuster trade.

The Lakers overshadowed the NBA Draft by completing a deal to get Westbrook from the Washington Wizards, who receive Kyle Kuzma, Montrezl Harrell and Kentavious Caldwell-Pope in return.

The Wizards also got the 22nd pick in Thursday's first round – Isaiah Jackson was taken at that slot, then traded to the Indiana Pacers in exchange for point guard Aaron Holiday – while the Lakers gained two second-round selections in future drafts, according to reports.

For Westbrook, it means yet another fresh start. The 32-year-old ended his long association with the Oklahoma City Thunder when reuniting with James Harden at the Houston Rockets in 2019, only to then leave for Washington a year later.

Despite only spending one season with the Wizards, Westbrook declared his appreciation for all connected with the franchise in an Instagram post after news of the deal had emerged.

"Thank you DC! You welcomed my family and I with open arms from day one," he wrote.

"Everyone from the front office to the training staff, the coaches, my team-mates, and the fans. I’m grateful y'all took a chance on me and supported me every step of the way.

"I'm blessed to have been a part of such a stand-up organisation. It didn't take long to make a home in DC, and I will forever be grateful and appreciative of my experience with the organisation. Thank you."

LeBron, meanwhile, used his Instagram account to put up a picture of himself and fellow Lakers star Anthony Davis standing either side of the team's latest recruit, along with the caption "Brodie", which is Westbrook's nickname.

The addition is a move aimed at getting the 2019-20 NBA champions back into contention. The title defence did not go to plan last term, long-term injuries to their two stars leading to a struggle just to make the postseason. While they did qualify, the holders were knocked out in the first round by the Phoenix Suns.

As for Westbrook, his year with the Wizards included a key role in a late charge to make the playoffs via the play-in tournament, though they were beaten 4-1 in the first round by the Philadelphia 76ers, after which it was announced head coach Scott Brooks would be leaving his role.

Westbrook had broken an NBA record that had stood for 47 years during the regular season, moving beyond Oscar Robertson to top the list for career triple-double games.

He led the league for assists with 11.7 per game, as well as shooting 31.5 per cent from three-point range - his best return from deep sine the 2016-17 season. It will be fascinating to see how he fits into the Lakers' current roster, though it remains to be seen if they are finished making offseason moves just yet, considering free agency is around the corner.

There was speculation L.A. were also in negotiations to bring in Buddy Hield from the Sacramento Kings. The 28-year-old would add some much-needed outside scoring, seen as he is a career 40.6 per cent shooter from deep.

The Lakers finished at 35.4 per cent as a team from three-point range, ranking them 21st in the entire league. Caldwell-Pope was one of their more successful players when it came to taking aim from distance, finishing up at 41.0 per cent, but he has been moved on in order to add a new playmaking presence.

Westbrook, who is from California and played at UCLA during his college career, will earn $44.2million in 2021-22, then has a player option worth $47m for the following year.

The term "positionless" has been all the buzz in the NBA the last few years, and the first round of the 2021 draft followed that trend as the Detroit Pistons took Cade Cunningham with the first overall pick and players with similar skill sets went off the board soon after. 

Longstanding positional terms like guard, forward and center have gone out the window as athletic players like NBA MVP Nikola Jokic of the Denver Nuggets have taken over the league, and Cunningham leads the latest crop of versatile options. 

Checking in at 6-foot-8, Cunningham often plays like a point guard, leading his team down the floor – exactly the kind of headache-inducing matchup teams are seeking these days. 

After the Houston Rockets took guard Jalen Green second overall and the Cleveland Cavaliers used the third pick on big man Evan Mobley, the Toronto Raptors surprised many prognosticators by taking another of those positionless players at number four with Scottie Barnes. 

At 6-foot-9, his role at Florida State was similar to Cunningham's at Oklahoma State, running the offence while defending across multiple positions. 

"He's a multi-faceted, multi-positional two-way player," Raptors head coach Nick Nurse told reporters. "We like guys that can handle, pass, score, defend, rebound a little bit and just kind of come at you in waves with that." 

Most had expected Gonzaga guard Jalen Suggs to be Toronto's pick after US fans fell in love with him during the NCAA Tournament, but he fell to the Orlando Magic at number five. 

The Okahoma City Thunder then took yet another 6-8 talent in Australia's Josh Giddey at number six in a move that caught many off guard. 

It was more of the same with the following pick as the Golden State Warriors took Jonathan Kuminga, a player who can defend anyone and is unafraid to launch from three-point range. 

It was that kind of night as NBA teams added young talent while trading players and picks in this and future drafts.

Because most transactions cannot become official until August 6, teams selected players they know they will not keep due to deals made ahead of and during the draft. 

Those types of moves prevailed in the latter half of the first round, with numerous reported trades on the cards. 

Among them, yet another versatile big man in Turkey's Alperen Sengun, who was drafted at number 16 by the Oklahoma City Thunder but reportedly will play for Houston. 

The 6-foot-10 Sengun told reporters he believes his passing abilities will help him excel as other European imports have done before him. 

"With my new team, Houston, I will bring something different on the court," he said. "I will do whatever it takes and whatever is needed." 

As the lines between positions and roles continue to blur in the NBA, that approach has increasingly become the default setting across the board.

The Los Angeles Lakers are set to add another former MVP, as several media outlets reported they will acquire Russell Westbrook from the Washington Wizards in a draft-night blockbuster. 

In return for Westbrook and second-round picks in 2024 and 2028, the Lakers reportedly are sending Kyle Kuzma, Montrezl Harrell, Kentavious Caldwell-Pope and the 22nd overall pick in Thursday's draft to Washington. 

While the deal cannot be officially completed until August 6, when the salary cap for next season is set, commissioner Adam Silver announced the portion involving the draft pick from the podium on Thursday. 

With the 22nd pick that was part of the trade, the Lakers selected Isaiah Jackson from Kentucky and sent him to Indiana as part of a separate deal between the Indiana Pacers and Wizards that reportedly will net Washington Aaron Holiday and the number 31 pick.

But Los Angeles native and former UCLA star Westbrook was the man everyone was talking about on Thursday. 

After one season with Washington, Westbrook will head west to join LeBron James, Anthony Davis and the Lakers as they try to bounce back from a first-round playoff loss a year after winning the NBA title. 

The move will cost LA, who will owe their new star trio a combined $121million next season. 

But the Lakers will be hoping for big things from the nine-time All-Star Westbrook, who was the league's MVP in 2016-17 while playing for the Oklahoma City Thunder and turns 33 in November. 

Westbrook averaged 22.2 points and a career-high 11.7 assists and 11.5 rebounds in 65 regular-season games last season, recording triple-doubles in 38 of them.

Along the way, he broke Oscar Robertson's long-standing record of 181 career triple-doubles, finishing the season with 184. 

From Washington's perspective, moving on from Westbrook frees up money to keep Bradley Beal as the team's centerpiece moving forward as he enters the final year of his contract. 

The Wizards also added some supporting pieces in the deal, as Harrell averaged 13.5 points and 6.2 rebounds for the Lakers last season, while Kuzma contributed 12.9 points and 6.1 rebounds and Caldwell-Pope 9.7 points.
