Brooklyn Nets head coach Steve Nash said while Kevin Durant "looks great", the former MVP is likely to miss another week as he continues to recover from a hamstring injury.

Durant has been sidelined since February 13 due to a hamstring strain, which forced him to sit out the NBA All-Star Game this month.

As the star-studded Nets prepare to face the Minnesota Timberwolves on Monday, Nash provided an update on Durant.

"There's still steps for him to take, although he looks great, is progressing and will definitely be back with us," Nash said.

"It's just, I don't think this week is likely."

Durant is averaging 29.0 points, 7.3 rebounds and 5.3 assists per game for the Nets this season.

Nash added: "[He] still needs to be monitored and still needs to get a certain amount of markers under his belt."

The Nets, though, will welcome back star Kyrie Irving following a three-game absence due to a family issue.

Irving is averaging a career-high 28.1 points, 5.7 assists and 4.8 rebounds per game for the Nets in 2020-21.

The seven-time All-Star's field-goal percentage this season (52.0) is also a career-high.

Brooklyn (31-15) – who have recruited veteran All-Star LaMarcus Aldridge – are second in the Eastern Conference, one game behind the Philadelphia 76ers (32-14).

It is safe to say LaMelo Ball has hit the ground running in the NBA.

The hype has long followed Ball and his rise in the basketball world, dating back to his high school days. His outspoken father tipped him to be a future number one draft pick – LaVar talking up his son at every turn.

While he was not the first name called on Draft night last year, LaMelo – the younger brother of New Orleans Pelicans guard Lonzo – has lived up to his billing since the Charlotte Hornets used the third pick on the 19-year-old sensation.

Prior to suffering a wrist fracture in March, Rookie of the Year favourite Ball ranked first in assists and steals among rookies, second in scoring and is tied for second in rebounds.

The face of an emerging and exciting franchise boasting Gordon Hayward, Terry Rozier, DeVonte Graham and Miles Bridges, Ball was the only player over the last 60 years to lead all rookies in total points, rebounds, assists and steals at the All-Star break.

Last month, Ball joined Stephen Curry (2010) and Jason Kidd (1995) as the only rookies with seven-plus threes and 10-plus assists in a game and was the youngest to do so. He also became the youngest player in NBA history to record a triple-double in January.

"I'm really pleased for LaMelo that, not only has he gone to a situation that allows him to showcase what he can do, but the people around him from top to bottom really care about his development as a player and a person," Matt Flinn, who coached Ball during his time with the Illawarra Hawks in Australia's NBL prior to the draft, told Stats Perform News.

"We keep forgetting he's only 19. Can you imagine in three years when he's 22? Doing what he's doing now is quite special. In three or four years' time, he's going to be a superstar of the NBA."

Ball's playmaking ability has been on show throughout the 2020-21 campaign, right up until he hurt his wrist against the Los Angeles Clippers and underwent surgery – the fracture was reported to be potentially season-ending, though the Hornets have not ruled out a return.

By March 25, he had featured in the top 20 for assist percentage (33.4), a list including experienced stars, champions and former MVPs like Russell Westbrook, Luka Doncic, James Harden, Trae Young, LeBron James, Nikola Jokic, Chris Paul, Jimmy Butler, Damian Lillard, Draymond Green, John Wall, DeMar DeRozan, Curry, Ben Simmons and Kyle Lowry.

His assists/turnover ratio stands at 2.18 – better than Los Angeles Lakers legend James.

"You just look at his numbers – possessions plus assists, if you look at the guys with more than 800 possessions, he's sitting in the top 25 in the NBA. When you go through the list, the guys on that list, it's quite incredible for a 19-year-old," Flinn said, having tipped Ball to flourish in the NBA during a pre-draft interview with Stats Perform News.

"When we recruit guys, we look at assist/turnover ratio. Again, that's testament he's hitting the positive column for his usage rate. The ride for LaMelo is just beginning."

Through 41 games, Ball is averaging 15.9 points, 5.9 rebounds and 6.1 assists this season in just 28.6 minutes per game. He would be the first player in NBA history to average 15/5/5 in less than 30 minutes per game in a season (minimum 40 games played), per Stats Perform.

When you compare his first 41 games to some of the past and current greats at the same stage, Ball ranks well.

His points-per-game average is better than five-time champion and Lakers great Kobe Bryant (7.0 in 1996-97), former MVP Harden (9.8 in 2009-10), Curry (13.4 in 2009-10), Steve Nash (4.5 in 1996-97) and Jason Kidd (9.4 in 1994-95).

When it comes to his assists numbers, Hall of Famer Michael Jordan (5.1 in 1984-85) – the owner of the Hornets – Nash (2.9), Dwyane Wade (4.3), Harden (2.1), Curry (4.6) and Kyrie Irving (5.7 in 2011-12) did not fare as good as Ball.

Highlighting his versatility, Ball's rebound average is better than Irving (3.8), Curry (3.8), Harden (3.2), Wade (4.4), Bryant (2.0), Nash (1.3), Kidd (5.7) and Allen Iversen (4.2 in 1996-97).

"It really doesn't surprise me," Flinn said when asked about some of the record-breaking numbers. "I'm not just saying it because the level of belief is probably the first thing that struck me about LaMelo.

"This kid was just born to play. You get a lot of players who are manufactured and they do an incredible amount of work, we put them in boxes in their roles they fulfill in teams. LaMelo really has no ceiling. You just have to look at him in transition and some of the passes he executes in the game.

"In transition, to be able to thread a needle and put the exact amount of spin on it so it holds up to hit a guy running at speed, you can't coach or teach that. Prior to him coming to me and going to Charlotte, he copped a lot of criticism, his family copped a lot of criticism for the show, whatever he did within his journey etc, but they've done an incredible job in the point leading up to me.

"Having allowed him to fail at times in some of the games he played. You look at the old mainstream coaching, 'Well we put accountability on our players and if you turn it over or don't stick to the system, we're dragging you'. That never happened with him during his pathway.

"They're certainly seeing the benefits of that now because when you strip it back now, he is a disciplined, great kid, who genuinely cares about his team-mates and makes people better around him. I'm so happy that he appears to have found his feet."

Flinn – who believes the Jordan-led Hornets have the potential to be a powerhouse in the next five years – added: "What I tried to do with him and what [Charlotte head coach] James [Borrego] is doing as well, even though you might be in a half-court situation, you try to get him downhill.

"When he gets downhill, he has so many escape routes when he commits. He will contest at the rim, he will leave his feet and have three escape routes. For me, that's the real special nature of his play.

"Always the question mark was his ability to shoot the ball [Ball is shooting at 45.1 per cent]. He will continue to get better shooting the ball no question. That will bring in a whole new dimension on how you defend him out of the pick and roll. He's still good enough to work in tight spaces.

"The first time I saw him throw a full-court baseball pass to hit a guy straight in the chest, I'll be honest, I thought 'what are you doing?'. But he rarely fails with those kinds of plays. He just has that unwavering belief. I said to him one time, 'if you weren't playing basketball, you'd probably be a quarterback given your arm and ability to read a player'. It's unique."

Ball was the favourite to be crowned the 2020-21 Rookie of the Year before he was struck down by injury. Does he still deserve the award?

"I might be biased but I really hope so. He is a once-in-a-generation player for the NBA," added Flinn, who said Ball would be devastated following the wrist injury as he "lives, eats and sleeps basketball".

"I believe he'd take winning over anything, but it would be something he'd deserve given the body of work he's been able to produce so far. I don't think you'd have too many arguments."

Lewis Hamilton was thrilled to come out on top in a dramatic Bahrain Grand Prix, which he labelled as one of the toughest Formula One races he has been involved in for some time.

Max Verstappen started on pole in Bahrain, but despite the Red Bull having had the edge over Hamilton's Mercedes in practice and qualifying, it was the seven-time world champion who triumphed.

It did not come easy for Hamilton, who had to see out a late attack from Verstappen to secure his first season-opening success in six years.

The victory only came courtesy of an error from the Red Bull driver, who was adjudged to have gone beyond track limits during a potentially decisive overtake with four laps left to go, and was instructed to immediately give the place back.

If Sunday's evidence is anything to go by, Verstappen and Red Bull are well placed to make more of a challenge this season.

Speaking in his post-race interview, an exhilarated Hamilton said: "Wow! What a difficult race that was.

"Stopping early we knew would be difficult but we had to cover Max, they have had an amazing performance all weekend.

"We suffered the last stint. Max was all over me at the end and I was just about able to hold him off. That was one of the hardest races I've had for a while."

Asked if he was at the peak of his powers, 36-year-old Hamilton replied: "I definitely am. Each year they are talking about when you hit your peak and timing is everything.

"I think I am at that and Max is doing really well at the moment. I love the challenge."

Verstappen, meanwhile, looked to take the positives after crossing the line just 0.745 seconds after Hamilton.

"It's a shame but you also have to see the positive. We are really taking the fight to them, and I think that's great to start the year like that," Verstappen said.

"I don't know what happened with the car early on. It don't think it was completely solved in the low-speed corners, so we'll have a look at that. Overall, we managed to finish the race and score good points."

It was a sentiment echoed by Red Bull chief Christian Horner, with the team's principal believing they are finally ready to mount a serious title push this year.

"A great race, a tough one to lose. It is the first of 23 so hopefully, we give Lewis a harder time this year," Horner told Sky Sports.

"Once you have that instruction [to give the place back] you have to move out of the way. It is tough racing, it is fair racing.

"The races come thick and fast once we get going. Mercedes have been so strong over the years. I think the biggest winner today was the fans. It sets up a great season and I hope we see more battles between Max and Lewis this season."

Lewis Hamilton clung on to survive a late attack from Max Verstappen to begin his Formula One title defence with a dramatic victory in the Bahrain Grand Prix.

Verstappen's Red Bull had the edge in speed over Hamilton's Mercedes for the entirety of the race weekend but, after a frenetic stop-start opening to the race gave way to a strategic battle between the teams expected to compete at the front of the grid this season, it was the Briton who found himself taking the chequered flag.

Having emerged from his final pit stop nearly nine seconds behind Hamilton, pole-sitter Verstappen looked to have made the crucial overtake with four laps remaining.

But he was forced to give the place back having gone beyond the track limits to get past Hamilton, and Verstappen could not find an opportunity with which to make the decisive move for a second time, Red Bull left frustrated as the seven-time champion claimed his first season-opening win since 2015.

Sebastian Vettel will start his first race for Aston Martin at the back of the grid after being hit with a penalty at the Bahrain Grand Prix.

Vettel has been penalised for ignoring yellow flags in qualifying at the Bahrain International Circuit in Sakhir on Saturday.

The four-time Formula One world champion breached the rules when Haas driver Nikita Mazepin spun at Turn 1 during Q1, resulting in double waving of yellow flags - which Vettel failed to respect.

Vettel qualified in 18th but was given a five-place penalty and hit with three penalty points after being summoned to the stewards ahead of Sunday's race.

The stewards said in their verdict: "[Valtteri] Bottas, Vettel, [Sergio] Perez and [George] Russell approached the scene and drove past Mazepin. Bottas, was immediately instructed by his team to abort his lap in accordance with the Race Director's Event Notes.

"Perez and Russell had received the chequered flag, and were instructed to slow, with Russell receiving the additional information that it had been a double yellow sector.

"Vettel did not abandon his lap. He explained to the stewards that he saw the smoke ahead of him, but was unsure if it was a lock-up or a stopped car until he was quite close to the car and the smoke was lifting.

"The stewards observed that he had already passed the signal panel when it illuminated as he approached the scene, and that the marshals in that turn had not yet reacted with a yellow flag. Nevertheless, Vettel was approaching a car that was stopped sideways on the track and by the rule this would necessitate a double yellow flag."

Vettel said: "We were already quite far back so it doesn't make a difference.

"Hopefully we will come up with something clever with strategy so we can move up and enjoy it along the way."

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.

Saturday's results

Washington Wizards 106-92 Detroit Pistons
New York Knicks 102-96 Milwaukee Bucks
Houston Rockets 129-107 Minnesota Timberwolves
San Antonio Spurs 120-104 Chicago Bulls
New Orleans Pelicans 112-103 Dallas Mavericks

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."
