Adelaide United made it six wins on the spin to climb up to second in the standings, while there was also a victory for Macarthur FC in Sunday's A-League action.

Craig Goodwin converted a 76th-minute penalty as in-form Adelaide continued their hot streak, though they needed goalkeeper Joe Gauci to make a crucial late save to deny Patrick Wood an equaliser in stoppage time.

Sydney had 14 attempts but managed just four on target, meaning they slipped to a first defeat against their opponents in 13 league meetings.

Adelaide now sit a point behind leaders Central Coast Mariners with a game in hand and are on their longest unbeaten streak since a seven-game run between November 2005 and January 2006.

Just the one goal was enough for Macarthur, too, Denis Genreau on target in a 1-0 triumph over Wellington Phoenix in the early kick-off.

Wellington had lost only one of their previous five games going into the contest, but Genreau was in the right place to tap in a loose ball from close range.

It was the second A-League encounter between the teams, with January's meeting having ended in a 1-1 draw.

Zion Williamson is a "Shaquille O'Neal-type force" with skills like a point guard, according to Rick Carlisle, who saw his Dallas Mavericks struggle to contain the New Orleans Pelicans forward.

Having finished with a career-high 39 points in a loss to the Denver Nuggets in his previous outing, Williamson had 38 to help the Pelicans get back to winning ways on Saturday.

The 20-year-old contributed 10 points in a pivotal 18-8 run in the closing stages as he took over proceedings, helping New Orleans eventually prevail 112-103 as they claimed a third win in four outings.

Mavs coach Carlisle admitted his team found Williamson – who landed 12 free throws from 18 attempts, both season-high numbers – too much to handle with the game on the line.

"He's an unusual force and obviously a great player," Carlisle said.

"We'll have to figure something a little better out next time, but he's doing this to everybody. We did have some very good possessions guarding him, but he was a beast.

"It presents huge challenges for the defense and for officials. He is just creating collisions out there. This is a Shaquille O'Neal-type force of nature with a point guard skill set."

Williamson is averaging 26.3 points per game in his second season in the league, shooting 62.8 per cent from the field.

The first overall pick in the 2019 draft has had five games in this campaign with at least 15 field goals attempts and an 80 per cent success rate, the most by any NBA player since Charles Barkley had five in 1988-89 when playing for the Philadelphia 76ers.

Only two-time MVP Giannis Antetokounmpo (412) and Atlanta Hawks guard Trae Young (389) have taken more free throws than Williamson (364) so far this term, while he is also averaging seven rebounds per game.

His improvement as a playmaker is also impressive. Having averaged 2.1 assists in a rookie season that was limited to just 24 games, he is up at 3.5 through 43 outings in 2020-21, including 16 across in the last three for a Pelicans team fighting hard to make the playoffs.

However, while flattered by links to the legendary O'Neal, as well as other NBA greats, Williamson wants to leave his own legacy.

"I am who I am. I'm Zion. I'm trying to be the first and only Zion, that's all there is to it," he said after dazzling against Dallas.

The Pelicans are now 20-25 for the season to sit 12th in the Western Conference, with 14 of their victories coming in home games.

Francis Ngannou set his sights on Jon Jones after sealing a devastating knockout win in his rematch with Stipe Miocic to claim the heavyweight title at UFC 260.

Ngannou became the undisputed champion as he gained revenge after being outclassed by Miocic three years ago at UFC 220, the Cameroonian landing a brutal and decisive blow with a left hook in the second round.

And now the 34-year-old wants a shot at Jones, with the legendary American poised to step up to the heavyweight division later this year.

Ngannou lauded Jones as the GOAT of MMA, but declared he was ready for the challenge.

"In my opinion, Jon Jones is the greatest of all time in mixed martial arts. Him moving up is going to be a good thing," he said after his stunning victory in Las Vegas.

"He's a challenge I will take, and it will be a very good thing on the resume. But this time he is the challenger. I am the champ. He's coming up, looking for me.

"So I'm ready any time soon. Even summer, I will be here, ready to fight in July or August. Whenever they are ready, I'm ready.

"He said something, 'Show me the money'. Show the money and we'll go, baby. I'm here."

Miocic – who was coming off a unanimous decision win over Daniel Cormier at UFC 252 last August – was left stunned by an overpowering display from Ngannou, who got the job done 52 seconds into round two.

Doc Rivers has backed his old team the Los Angeles Clippers to battle it out with the LA Lakers to take the honours in the Western Conference.

The Clippers spoiled Rivers' return as they downed his Eastern Conference-leading Philadelphia 76ers 122-112 on Saturday.

It was Rivers' first meeting with the Clippers since he was fired in the offseason, having let slip a 3-1 series lead in the second round of the playoffs against the Denver Nuggets.

But it was not a warm welcome on the court, where the 76ers had their four-game winning run brought to a grinding halt.

Kawhi Leonard put up 19 of his 28 points in a dazzling first half, with Paul George contributing 24.

It left Rivers in no doubt as to who the leading contenders are in the West, with the Clippers and the Lakers getting the nod ahead of the Utah Jazz – who currently lead the way in the standings – the Nuggets and the Portland Trail Blazers.

"I thought Denver had a great trade deadline – they did great moves," Rivers said. "Utah is playing unbelievable basketball, so they are going to be right there. Portland, I thought improved their team as well.

"But I still think it's the Lakers and the Clippers."

With Ty Lue now at the helm, Rivers acknowledged there are many differences to the team he coached, but pointed out that the Clippers had a solid platform to build on following his departure.

"They're a different team," Rivers said. "They don't have a lot of the same guys, [but] they run a lot of the same stuff that I run.

"Going through [their plays at] shootaround today, I thought we were going through our shootaround at times. But I wouldn't have changed much offensively, either. I mean, they were pretty darn good last year.

"The difference is they've had a chance to practice together, you know? And you can see that. I think they've given the ball to PG [George] more, which I think has helped him. So they've made some good changes.

"The biggest change I see also is defensively. I think they are a better defensive team. It's funny, the numbers don't exactly say that, but when I watch them, I think they're going to be a better defensive team, one of the better defensive teams when the playoffs start."

Terance Mann had a season-high 23 points for the Clippers on 10-of-12 shooting from the field, while he made both of his three-point attempts.

The 76ers had a six-game road winning run ended, despite a game-high 29 points from Tobias Harris.

The Los Angeles Clippers spoiled Doc Rivers' return as they topped the Eastern Conference-leading Philadelphia 76ers 122-112 in the NBA.

Rivers reunited with the Clippers for the first time since being fired and joining the 76ers in the offseason, having led the Los Angeles franchise to six playoff appearances.

But Rivers did not have much to celebrate after the 76ers had their four-game winning streak snapped on Saturday.

Kawhi Leonard posted 28 points – 19 in the first half – and Clippers team-mate Paul George added 24 of his own in Los Angeles.

Terance Mann had a season-high 23 points for the Clippers on 10-of-12 shooting from the field, while he made both of his three-point attempts.

The 76ers had a six-game road winning run ended, despite a game-high 29 points from Tobias Harris.

Mitchell sparks Jazz

Donovan Mitchell put up 35 points as the NBA-leading Utah Jazz defeated the Memphis Grizzlies 126-110. Mitchell was efficient in Utah, where he was 12-of-17 shooting from the field, to go with his five three-pointers from seven attempts in 28 minutes. All-Star team-mate Rudy Gobert (16 points and 14 rebounds) contributed a double-double.

Gregg Popovich became the third coach in NBA history to reach 1,300 regular-season wins following the San Antonio Spurs' 120-104 victory against the Chicago Bulls. Only Don Nelson (1,335) and Lenny Wilkens (1,332) have had 1,300 wins or more. All-Star Nikola Vucevic had 21 points and nine rebounds in his debut for the Bulls after being traded by the lowly Orlando Magic.

Zion Williamson's 38 points led the New Orleans Pelicans past the Dallas Mavericks 112-103. Tim Hardaway Jr. had 30 points off the bench for the beaten Mavericks.

Russell Westbrook's triple-double of 19 points, 19 rebounds and 10 assists fuelled a 106-92 win for the Washington Wizards against the Detroit Pistons.

The Milwaukee Bucks were upstaged 102-96 by the New York Knicks despite double-doubles from two-time reigning MVP Giannis Antetokounmpo (23 points and 10 rebounds), Jordan Nwora (21 points and 10 rebounds) and Brook Lopez (12 points and 10 rebounds).

Awful Richardson

The Mavericks went down to the Pelicans and Josh Richardson struggled. The shooting guard finished one-of-11 from the field. Richardson missed all four of his attempts from beyond the arc for a measly four points in 34 minutes.

Mike Scott – in the starting five for the 76ers – finished with just three points in Los Angeles. He was one-of-six from the field, making just one three-pointer in 29 minutes.

Barnes calls game!

With the Sacramento Kings trailing 98-97, Harrison Barnes nailed a buzzer-beating three after catching a full-court pass to sink the Cleveland Cavaliers. De'Aaron Fox's 36 points set the tone for the Kings, who edged the Cavaliers 100-98.

Suns at Hornets

The high-flying Phoenix Suns (30-14) – second in the west – will visit the in-form Charlotte Hornets (23-21) on Sunday. Charlotte have won three straight games to sit fourth in the Eastern Conference.

Francis Ngannou annihilated Stipe Miocic with a brutal second-round knockout in their blockbuster rematch to become the UFC heavyweight champion.

Ngannou was outclassed by Miocic three years ago, the Cameron fighter unable to take the title away from his opponent at UFC 220 in 2018.

But Ngannou (16-3) exacted revenge on Saturday thanks to his brutal KO of the titleholder at UFC 260 in Las Vegas, where a new champion was crowned.

Ngannou earned another title shot following knockout wins against Curtis Blaydes, Cain Velasquez, Junior dos Santos and Jairzinho Rozenstruik.

The 34-year-old dethroned Miocic (20-4) inside the UFC Apex, where he had the American fighter in trouble early in the second round after dropping the champion with a two-punch combination.

Miocic – who was coming off a unanimous decision win over Daniel Cormier at UFC 242 last August – was left stunned after being swarmed with punches on the chin and Ngannou followed with a hammer fist on the ground as the referee waved off the fight.

Afterwards, Ngannou talked up a showdown with former champion Jon Jones.

"It's a challenge that I'll take and a very good fight on my resume," Ngannou said post-fight.

"He's the challenger, I am the champion so he's looking for me. I'm ready to fight in July and August. Let's do it." 

In the co-main event, Vicente Luque stunned former welterweight champion Tyron Woodley, who was forced into submission in the opening round.

It condemned Woodley to a fourth consecutive defeat as Luque earned the biggest win of his career.

"I want to take this time also to call out Nate Diaz," Luque said. "I called him out in the past and he didn't respond. My style, it matches perfect. I'm going to go forward. I think Nate is a perfect fight."

Stefanos Tsitsipas continued his strong run of form en route to the Miami Open third round, while Aslan Karatsev's maintained his fairytale run in 2021.

Greek star Tsitsipas flexed his muscles in a straight-sets win over Damir Dzumhur on Saturday.

Australian Open semi-finalist and Dubai Tennis Championships winner Karatsev enjoyed a victorious Miami debut.

Andrey Rublev, Diego Schwartzman, Denis Shapovalov, Marin Cilic and Milos Raonic also progressed at the ATP 1000 tournament.

TSITSIPAS STAYS HOT

World number five Tsitsipas eased past Dzumhur 6-1 6-4 in his first appearance since losing in last week's Mexican Open final.

Tsitsipas (15-4) became the third player to reach 15 wins this season, the second seed following in the footsteps of Russian duo Rublev (17-3) and Daniil Medvedev (15-2).

"It was a great match, especially against a guy that I probably don't have a good record playing against in the past," said Tsitsipas. "I started the match very strong, breaking him twice and taking a big lead in the score, and I think the things worked out by themselves after that."

Tsitsipas will face Kei Nishikori after the Japanese outlasted Aljaz Bedene 7-6 (8-6) 5-7 6-4.

NO STOPPING KARATSEV

Karatsev's Miami Open debut ended in a 6-4 6-3 win for the 17th-seeded Russian over Mikhail Kukushkin.

Already in the ATP's top 100 and set to keep climbing, Karatsev broke serve four times en route to the next round, where Sebastian Korda awaits after upstaging 10th seed Fabio Fognini 1-6 6-4 6-2.

"Of course it gives me confidence to win my first title, but you arrive here and it’s a different surface and new tournament," said Karatsev, who ended last season ranked 112th before bursting into the top 30 behind his semi-final run at Melbourne Park. "So you try [to think of it] as a new tournament and new place, but of course it gives me a lot of confidence."

Karatsev owns a 13-2 record this year, with his only two losses coming against world number one Novak Djokovic and US Open champion Dominic Thiem.

RUBLEV ROLLS ON

Fourth seed Rublev has proven to be remarkably consistent, highlighted by his crushing 6-1 6-2 rain-interrupted victory against Tennys Sandgren.

Having equalled his previous best run in Miami, Rublev will play 29th seed Marton Fucsovics who took down Thanasi Kokkinakis 7-6 (7-3) 6-7 (4-7) 6-4.

Rublev has won a Tour-leading 17 matches this year.

Elsewhere, fifth seed Schwartzman was a 6-3 6-3 winner against Yasutaka Uchiyama, Shapovalov – the sixth seed – trumped Ilya Ivashka 6-7 (5-7) 6-4 6-4 in a marathon, 12th seed Raonic accounted for Jordan Thompson 6-2 6-1, former US Open winner Cilic surprised 13th seed Christian Garin 3-6 7-5 7-6 (7-5), while 15th seed Alex de Minaur was eliminated.

World number one Ash Barty moved through to the last 16 of the Miami Open, where Simona Halep's campaign came to a premature end.

Defending champion and top seed Barty was too good for Jelena Ostapenko in Saturday's showdown between the former French Open winners.

Two-time grand slam winner Victoria Azarenka also moved through to the fourth round of the WTA Premier tournament.

Halep, however, succumbed to a shoulder injury in Miami.

CLASH OF PAST AND PRESENT NUMBER ONES

Barty and former world number one Azarenka will go head-to-head for a place in the quarter-finals.

Australian star Barty accounted for Ostapenko 6-3 6-2 as she extended her winning streak at the Miami Open to eight matches.

Barty, who tallied nine winners to 14 unforced errors, rallied from 2-0 down in the second set by reeling off six successive games to advance.

"Today felt like I was a lot sharper and switched on and ready to go from the very first point," Barty said afterwards.

Three-time Miami champion Azarenka trumped Angelique Kerber 7-5 6-2 in the third round.

Azarenka – the 14th seed – fought back from a 4-1 deficit in the opening set to get the better of the three-time major winner.

"She's a very talented player. I always have been a huge fan of her game and the way she plays, the way she handles herself. She has a lot of variety," Azarenka said on facing Barty. "She has pretty much every single shot there is. [It's] going to be a great match."

INJURED HALEP PULLS OUT

Two-time grand slam champion Halep withdrew due to a shoulder injury as Anastasija Sevastova benefited from a walkover.

"I'm very sorry to I have to pull out of the singles and doubles at the Miami Open, but my injury doesn't let me play here as expected," said Halep.

"I'm sad that I can't continue, I wanted to come here to give my best and play many matches but unfortunately I can't. 

"Hopefully next year I will come back healthy and better."

Next up for Sevastova is wildcard Ana Konjuh, who stunned 15th seed and reigning French Open champion Iga Swiatek 6-4 2-6 6-2.

SVITOLINA AND SABALENKA ROLL ON

Ukrainian fifth seed Elina Svitolina booked her spot in the round of 16 after overcoming fellow seed Ekaterina Alexandrova 7-6 (7-1) 6-4.

Two-time Wimbledon winner Petra Kvitova stands in the way of a quarter-final berth – the ninth seed was too good for 17th seed Johanna Konta 6-1 6-2.

Seventh seed Aryna Sabalenka, meanwhile, prevailed 7-6 (7-4) 6-4 against Veronika Kudermetova.

Belinda Bencic – the 11th seed – was sent packing 4-6 6-4 6-4 by Marketa Vondrousova, who will take on Sabalenka.

The Oklahoma City Thunder have shut down five-time All-Star Al Horford for the remainder of the season as the NBA franchise prioritise youth development.

Horford arrived from the Philadelphia 76ers at the start of the season and the veteran has had a significant impact on the rebuilding Thunder.

But the 34-year-old will not feature for the Thunder again in 2020-21, though he plans to remain with his team-mates and train in Oklahoma City ahead of an expected trade.

"We've talked with Al from the time he became a member of the Thunder this offseason about the many ways in which he would be able to help us as we entered the early stages of the necessary transition of our team," Thunder general manager Sam Presti said in a statement on Saturday.

"From day one Al has been a consummate professional and has had a tremendous influence on the team on and off the floor with his work ethic and total commitment to his team-mates.

"Our conversations have been open and ongoing about how to maximise this season for him personally as well as the development of our team.

"Al has been nothing short of spectacular and will remain a part of the team as we build on an approach and mentality that we have taken for some time."

Horford has been averaging 14.2 points, 6.7 rebounds and 3.4 assists per game for the Thunder this season.

Throughout his career, Horford is averaging 13.9 points, 8.2 rebounds and 3.3 assists in the NBA.

Horford, who has two years and $53million on his contract, added: "When I arrived, I understood the direction of the team, we had a great individual plan in place for me, and I feel like as a result I've played really good basketball for the Thunder.

"At the same time, I know what it's like to be a young, aspiring player, and at this point in the season I understand how important playing meaningful minutes is for their careers and their development.

"I also understand how important it is for the organisation to give them that opportunity. I'm looking forward to supporting the guys who supported me, watching them continue to play the right way and play together as we have throughout the season, while still being around the team and continuing my training."

Cristiano Ronaldo said he will "never change" following his angry outburst after the Portugal captain was denied a dramatic late winner in contentious circumstances against Serbia.

Ronaldo was convinced his last-gasp effort crossed the line, but the officials gave the all clear as 10-man Serbia rallied from two goals down to secure a 2-2 draw in World Cup qualifying on Saturday.

Stefan Mitrovic made back-to-back goal-line clearances to thwart Portugal in stoppage time, though Ronaldo was left fuming as the superstar was adamant his effort crossed line in Belgrade, where there was no VAR in place to review the decision.

Ronaldo was booked for his protestations before he angrily threw his captain's armband on the floor and walked off the field with just seconds remaining.

Afterwards, Ronaldo used Instagram and social media to discuss the controversial incident away to Serbia in the Group A showdown.

"Being captain of the Portugal team is one of the greatest pride and privileges of my life," Ronaldo wrote. "I always give and will give everything for my country, that will never change.

"But there are difficult times to deal with, especially when we feel that an entire nation is being punished. Lift your head and face the next challenge now! Come on, Portugal!"

Portugal head coach Fernando Santos revealed "embarrassed" referee Danny Makkelie apologised post-match in the Serbian capital.

"The referee apologised to me in the booth and told me he was embarrassed," Santos said during his news conference. "I was in the dressing room with him and he apologised to me. He had told me on the pitch that he was going to see the images and that if it was the case he was calling me to apologise ... and so it was.

"It is the second time in a qualifying phase that they apologise after the game ... I told him on the field that such a test there is no VAR or goal line ... Incidentally, one of the things he told me was that the goal line was important… but I told him that the ball was half a metre inside the goal. There was no obstacle between the goalkeeper and the goal line.

"We have to rethink. The referees are human and make mistakes, but that's why there is the VAR and the goal-line technology to avoid this."

The result left Serbia and Portugal level on four points atop Group A, one point ahead of Luxembourg through two matchdays.

On the incident, Serbia boss Dragan Stojkovic added: "I never comment on referee's decisions whether they go our way or not. Mistakes by officials are part of the game and should be viewed as such. I didn't see it clearly, I can only pass a verdict after I've seen the replay.

"Ronaldo is a great player but we largely contained him tonight and in the second half we showed true grit and character to fight back from two goals down.

"We always knew what to expect from a top team like Portugal but against such opposition you have to be brave and never give up. This group of players is quickly learning that."

Billy Horschel, Matt Kuchar, Scottie Scheffler and Victor Perez are all vying for a spot in the WGC-Dell Technologies Match Play final after a day of upsets in Austin.

Stars Jon Rahm, Tommy Fleetwood and Sergio Garcia surprisingly crashed out in the quarter-finals as the underdogs ruled on Saturday.

The unpredictable tournament continued on the weekend after world number one Dustin Johnson, Justin Thomas, four-time major winner Rory McIlroy, U.S. Open champion Bryson DeChambeau and Patrick Reed were unable to advance beyond the group stage.

Spanish third seed Rahm topped Erik van Rooyen 3 and 2 in the last 16 before being upstaged by Scheffler 3 and 1 in the quarter-finals at the Austin Country Club.

"I felt like I played some really good golf," said Scheffler, who will meet Kuchar in an all-American clash for a spot in Sunday's decider. "I think I kept things bogey-free and I got some early leads and made sure that I kept the pressure on those guys and made them feel like they had to do something special to beat me, which they weren't able to do."

Fleetwood – the 21st seed – succumbed to Horschel after 19 holes, while former Masters champion Garcia was beaten by 31st seed Victor Perez 4 and 3.

American golfer Horschel and France's Perez will do battle in the semis.

Englishman Fleetwood was sent packing after hitting a hole-in-one during his last-16 victory – a drive out of bounds at the 12th seeding him come unstuck in the quarters.

It was a big day for 2013 champion Kuchar, who eliminated former world number one Jordan Spieth 1up before defeating Brian Harman 2 and 1.

Kuchar – the 52nd seed – was runner-up in 2019, with last year's event cancelled due to the coronavirus pandemic.

"Certainly golf's a funny game and I think there are times as a professional where you can feel so far away, you think, golly, I don't have it," Kuchar said.

"I'm racking my brain trying to find it, but then you plug in the right ingredient, the right key, and then all of a sudden it snaps back, and thankfully it's been working and I'm seeing progression. It's just finally now it's clicked and it's a lot more fun this way, I assure you."

Roberto Martinez was impressed by the way Belgium rallied to secure a 1-1 World Cup qualifying draw with a "very good" Czech Republic side.

Lukas Provod put Czech Republic in front five minutes into the second half via a rasping drive from 20 yards out at Sinobo Stadium on Saturday.

Belgium hit back to salvage a point in Prague courtesy of Romelu Lukaku's seventh goal in his last six games for his country.

Czech Republic struck the woodwork twice and Kevin De Bruyne hit the post before Tomas Soucek's last-gasp header was cleared off the line by Belgium defender Toby Alderweireld.

The two nations have four points apiece after two Group E matches early in the battle to qualify for next year's tournament in Qatar, with Czech Republic top on goal difference.

Belgium manager Martinez was pleased with the way his team responded to falling behind, having also fought back to beat Wales 3-1 on Wednesday.

"We were put in difficulty by a very good Czech team and we had to adapt, to change our way of playing and responding," Martinez said.

"We were able to react and that's what I will remember from this match. We did not accept the situation after conceding the goal. We have to do better, of course, but I'm pretty happy with the team's reaction."

Martinez revealed Dries Mertens was withdrawn due to a shoulder injury, but was unsure over the extent of the damage.

The Spaniard refused to be drawn on whether in-form striker Lukaku and key midfielder De Bruyne will be rested when the top-ranked side in international football face Belarus on Tuesday.

"We will look at each case separately. We will first regenerate the bodies, because playing three matches in seven days is not easy." he said.

LaMarcus Aldridge has agreed to join the star-studded Brooklyn Nets for the rest of the NBA season, according to his agent.

Aldridge – a seven-time All-Star – agreed to a contract buyout with the San Antonio Spurs earlier this month.

Now, the 35-year-old star will join forces with James Harden, Kevin Durant, Kyrie Irving and Blake Griffin in Brooklyn as the Nets eye their first NBA championship.

Aldridge's agent Jeff Schwartz confirmed the deal to ESPN on Saturday.

Averaging 19.4 points and 8.3 rebounds in his 15 NBA seasons, including nine with the Portland Trail Blazers, Aldridge has not played since March 1.

Aldridge is averaging 13.7 points and 4.5 rebounds per game in 2020-21.

Steve Nash's Nets (31-15) are second in the Eastern Conference, one-and-a-half games behind the Philadelphia 76ers (32-13).
