Brooklyn Nets head coach Steve Nash said the NBA title hopefuls are waiting to discover the severity of Kevin Durant's latest injury after the superstar was ruled out early in the loss to the Miami Heat.

The Nets endured a forgettable trip to Miami, suffering a buzzer-beating 109-107 defeat against the Heat, having seen Durant exit in the opening quarter due to a left thigh contusion on Sunday.

Durant missed 23 games because of a hamstring injury before returning this month and the Nets – eyeing their maiden championship – are hoping they are not without the former MVP for another sustained period.

"He's sore but we don't know how severe," first-year coach Nash told reporters post-game.

"We'll see tomorrow how he wakes up and go from there but right now nothing’s been determined."

Durant was hurt during the first quarter, appearing to tangle legs with Trevor Ariza on a drive to the basket during the first quarter.

The 11-time All-Star had played for just four minutes, going three-for-three shooting – including two successful attempts from beyond the arc – to finish with eight points.

Durant was out for nearly two months of the season due to a hamstring injury, making his return against the New Orleans Pelicans on April 7 with 17 points in just under 19 minutes.

The two-time NBA champion did not dress for the defeat to the Philadelphia 76ers (39-17) on Thursday, a result that means they hold the tie-breaker over the Nets (38-19) in the Eastern Conference, but was back in action on Saturday, scoring 25 in the victory over the Charlotte Hornets.

"The timing of everything this year has just been a tell-tale sign of what life is right now in terms of the uncertainty of a lot going on," said Nets star Kyrie Irving, who posted 20 points in the continued absence of superstar James Harden (hamstring).

"Anything could happen at any moment, so we don't want to take anything for granted. But anytime one of our team-mates goes down, anytime something like that happens, it's definitely going to take a hit for us. And he's just gotten back. We just pray that it's not too serious and he's able to recover, but it definitely has a hit on our continuity at times. But we're not making any excuses for each other.

"We're all professionals, the guys that are getting minutes right now, we need them. So it's going to turn eventually, but we've just got to find that continuity, that connectivity from the start of the game to the end."

Australian Astra Sharma scored a shock win over top seed Ons Jabeur in the final of the MUSC Health Women's Open, landing her first WTA Tour singles title.

The world number 165 made a slow start to the match but eventually overwhelmed Jabeur 2-6 7-5 6-1 in Charleston.

Having risen to 27th in the world rankings without a trophy to her name, the 26-year-old Jabeur looked to have an ideal opportunity to put that right.

Sharma recovered from the one-sided opening set to lead early in the second, and despite Jabeur getting it back on serve, the underdog surged ahead again to level the contest.

In her second WTA singles final and first for two years, Sharma went one step further than when she was runner-up in Bogota, racing through the deciding set as she swatted away Jabeur's threat.

Jabeur said the defeat was "very tough" to take, while Sharma said of her breakthrough week: "This has been an amazing event. I've really enjoyed playing here."

Lewis Hamilton believes his remarkable recovery to finish second at the Emilia Romagna Grand Prix on Sunday will prove "very valuable" this season.

In the second race of the year, Hamilton seemed set for a lowly finish at best.

Having lost first place to Max Verstappen at Turn One on the first lap of an epic affair, the defending champion, chasing his rival, ran off into a gravel trap midway through the grand prix.

Hamilton was briefly stuck against the wall, struggling to reverse his car back onto the track, before the W12 limped towards the pit under a shower of sparks.

But a red flag prompted by an incident involving team-mate Valtteri Bottas then brought the race to a standstill.

Hamilton had been ninth and a lap down, yet the restart allowed him to weave through the field and claim P2, behind Verstappen but still ahead of the Red Bull man in the drivers' championship.

"I think, without doubt, getting back to second and getting these points will be very valuable through the season," said the Briton.

"If I'd lost 25 points, that would have been hard to recover based on the fact that [for] Red Bull it's the first time that they've had a championship-winning car.

"Their car is incredibly fast. They were faster than us this weekend, definitely in qualifying trim but it looks like a little bit also in race trim.

"I don't know if they made a couple of mistakes – I think they did, Max did in qualifying for example otherwise he would have been on pole.

"But we've got a real close battle. We love the fact that it's a close battle and it's great to see McLaren back up there after such a long time, it's great to see Ferrari looking strong.

"So, there's going to be a lot of exciting races up ahead and challenging for all of us in so many different ways."

Although Hamilton's resurgence prevented Verstappen from taking an early lead in the standings, the Dutchman was delighted to land a blow in the title tussle, having trailed the Mercedes man in the season opener.

But he was also not getting carried away after a first win of the year.

"It's a very long season. We just have to keep on working very hard," Verstappen said. "I'm very happy with the result today, of course, but that's today.

"I'm of course going to be happy about today, but tomorrow, we start again. We have to keep on improving because there's still a lot of work to be able to keep doing this the whole season.

"It's great to be fighting against Lewis, Mercedes who, I think, as a team, have been so dominant and they're very difficult to beat.

"To be able to sit here now, now two races in a row, we were very, very competitive – that's very promising but no guarantees."

With his nose pressed against the wall and rivals crashing elsewhere on the track in torrid Imola rain, Hamilton could easily have retired following his crash.

He was not to know then that the collision between Bottas and George Russell would provide a reprieve, but he was delighted to be able to continue and learn "an amazing lesson" regardless.

"I remember just sitting there, looking at the barrier, and I refused to think that the race was over," Hamilton said. "I refused to believe that the race was done.

"I could have obviously just turned the car off and got out but I'm grateful that I didn't.

"I'm grateful that I did do a reverse and then, after that, just kind of getting out the car and trying to switch the anger and turn it into positive energy so that I could get back in and race forwards.

"It's an amazing lesson to be sent and experience."

And Hamilton, so often starting from the front of the grid, actually relished the chance to blaze past the opposition from ninth place.

"I loved it," he added. "That's how my career actually started as a kid, coming through.

"We had a really dodgy, old go-kart, so I was always starting at the back. It just took me back to my roots."

Roger Federer has confirmed he will grace the clay courts at the French Open and Geneva Open.

The 20-time grand slam champion made his comeback at the Qatar Open last month after a long absence following knee surgery.

Federer was beaten by Nikoloz Basilashvili at the quarter-final stage in Doha before opting against playing in Dubai and Miami.

The 39-year-old Swiss on Sunday announced he will feature on home soil in a Geneva Open event that gets under way on May 16.

World number seven Federer will also be in the draw for the second grand slam of the year at Roland Garros, where he reached the semi-final two years ago in his first appearance at the Paris major since 2015.

He tweeted: "Hi everyone! Happy to let you know that I will play Geneva and Paris.

"Until then, I will use the time to train. Can't wait to play in Switzerland again."

Rafael Nadal will be a strong favourite to surpass Federer's tally of grand slam titles in Paris, where he has won the French Open a record 13 times.

Lewis Hamilton apologised for his error at the Emilia Romagna Grand Prix but was relieved to be able to secure an outstanding P2 on Sunday.

Defending Formula One champion Hamilton, who started from pole, looked to have blown his chances of a podium finish when he ran off into a gravel trap while chasing Max Verstappen midway through the race.

But as his Mercedes limped back to the pit lane a lap down, an incident involving Silver Arrows team-mate Valtteri Bottas and Hamilton's one-time reserve George Russell brought out the red flag.

Neither man involved in the crash could continue, although both avoided injury, but the stoppage gave Hamilton time to regroup.

That he did and the Silver Arrows superstar climbed from ninth to second, behind only Verstappen in a stunning display of resolve.

"Awesome job, guys," the Briton told his team radio. "Apologies for that mistake earlier on."

After congratulating Verstappen and third-placed Lando Norris in the post-race presentation, Hamilton said: "On my side, it was not the greatest of days.

"It was the first time I've made a mistake in a long time, but I was grateful I was able to bring the car home still."

He added: "I was really, really grateful that we got to get going again and to get some points for the team. That was really important."

Having set the fastest lap time late in the race, too, Hamilton still leads the drivers' championship, a point ahead of Verstappen.

But he said such a scenario was not on his mind as he prepared to restart.

"I wasn't thinking about it," he said. "I was just trying to get over the gutting feeling it is when you make a mistake and just moving on from it, learning from it real quick.

"You don't have time to dwell on it. So, that's what I did, get back into racing spirit.

"I didn't know if we'd be able to overtake, because off-line was really wet, but I still had some really fun battles with all the guys."

Verstappen is not concerned by his placing in those standings, however, responding: "It's a long season. We'll stay calm."

The Dutchman was one of the few drivers to enjoy himself in difficult conditions, most notably in the approach to Turn One as he pushed past Hamilton.

"I surprised myself," Verstappen said. "Last week we were struggling a little bit off the line, but we worked really hard to make that better.

"In these tricky conditions, we did a great job."

Max Verstappen claimed victory at a remarkable Emilia Romagna Grand Prix where Lewis Hamilton twice sustained damage and a crash involving Mercedes team-mate Valtteri Bottas prompted a red flag.

An epic race encouraged optimism for a genuine title tussle in Formula One in 2021, with drama right from the outset and Hamilton fighting hard to rescue a superb second-placed finish.

The defending champion had started from pole, with Verstappen qualifying in third, behind Red Bull colleague Sergio Perez.

But Verstappen claimed the lead from Turn One in the rain at Imola, racing up alongside Hamilton and forcing his championship rival wide, where he sustained right wing damage.

While chaos ensued behind them, Hamilton held off Charles Leclerc to ensure he remained the biggest threat to Verstappen, with a tactical battle briefly allowed to develop.

Verstappen pitted first on lap 28, with Hamilton following a lap later and coming out behind the Dutchman following a slow stop.

But a manic spell then shook up the race again. First, Hamilton ran off into a gravel trap and desperately sought to reverse back onto the track.

The Briton was limping back to the pit lane a lap down under a shower of sparks, emitted by his Silver Arrow, when a further incident brought out the safety car.

Bottas collided with Mercedes prospect George Russell, driving for Williams, and both cars crashed in spectacular fashion, with the drivers emerging from the wreckage to angrily blame one another over the team radio.

The red flag soon followed, with wreckage spread across the track and a 30-minute suspension required, giving Hamilton time to regroup.

He resumed from ninth, able to unlap himself, with Verstappen forced to build a healthy lead again from Lando Norris after a slightly nervy restart.

Verstappen had retired at each of the three Italian races in 2020 but avoided a similar fate this time and the focus in the closing stages was instead on Hamilton's progress.

The Mercedes man picked off his opponents one by one, eventually streaking past Leclerc to move into position for a podium place once more.

Only Norris in the McLaren stood between Hamilton and a phenomenal P2 and he patiently chased down his compatriot to limit the damage and somehow emerge from this race a point ahead of Verstappen.

'AN UNFORTUNATE INCIDENT'

As the race got back underway following his crash, Russell posted on Twitter: "Thanks for all the messages. I'm fine, just disappointed.

"At the end of the day, it's an unfortunate incident. You're entitled to defend your position. But at 330kph, you have to respect the speed and the conditions when doing so. Gutted for the team. They deserved more today."

That was the second crash that ruled a driver out, with Nicholas Latifi earlier colliding with Nikita Mazepin to almost instantly exit the grand prix.

The subsequent safety car brought its own share of incident – Perez hit with a 10-second penalty after running wide and overtaking two cars to recover fourth.

Mick Schumacher went into a wall under the safety car, meanwhile, and lost his front wing.

TONE SET BEFORE THE START

The weather was always likely to cause havoc and the drivers took to the track to test their tyres ahead of the race. Even that did not go smoothly.

Fernando Alonso crashed into the wall, while the brakes on the Aston Martin cars caught fire.

That issue meant Sebastian Vettel had to start from the pitlane, and he was later given a 10-second stop/go penalty, too, for failing to have his wheels fitted in time.

Bottas sustained a puncture on his way to the grid and then Leclerc span on the formation lap. It was one of those days.

Stefanos Tsitsipas landed the first Masters 1000 title of his career as he scored a thumping 6-3 6-3 win over Andrey Rublev in Monte Carlo.

The Greek star had lost his previous two finals at this level, with Rafael Nadal denying him in Toronto and Novak Djokovic beating him in Madrid.

However, he had the measure of Russian Rublev on the Monte Carlo clay on Sunday, breaking his opponent's serve three times and giving away nothing on his own delivery.

Tsitsipas, who lives in Monte Carlo, said he had experienced an "unbelievable week", declaring it was the pinnacle of his career to date.

"I can't describe the feelings right now," he said on Amazon Prime. "I'm overwhelmed by so many different emotions.

"It's incredible I'm able to be in the position I am, and I think we both deserved being in the final and put on an amazing fight and an amazing show.

"Generally I would consider it the week of my life so far. I knew he was going to be a very difficult opponent to face and there were a lot of nerves coming into that match.

"I've played him in the past, he always wants to bring the best out of us when facing each other."

Rublev beat 11-time Monte Carlo champion Nadal in the quarter-finals, but the 23-year-old could not hit the heights of that performance in the title match.

Tsitsipas, 22, said: "I'm just proud of the way I managed to behave and to be out on the court today.

"The clay-court season couldn't start better and it's the best thing right now, winning my first Masters 1000, and it's even more special doing it here on home soil in Monte Carlo and doing it on clay which is my favourite surface."

Fabio Quartararo overcame a poor start to win a dramatic Portuguese Grand Prix that saw Marc Marquez finish seventh on his long-awaited return.

Marquez said he was ready to "suffer" in his first race since sustaining a season-ending broken arm last July, but the six-time MotoGP champion enjoyed an encouraging comeback after making an early move from sixth to third.

However, it was Quartararo who took the victory, despite dropping down the field from pole position in a pulsating start, after Johann Zarco and Alex Rins crashed out in quick succession at the Algarve International Circuit on Sunday.

Quartararo took over from Zarco as championship leader after sealing back-to-back wins following his triumph in Doha, with Francesco Bagnaia and Joan Mir taking second and third place respectively.

Maverick Vinales could only finish back in 11th place on a great day for Quartararo.

Zarco darted up the inside in a dream start from third on the grid to take the lead from Monster Energy Yamaha rider Quartararo, with Marquez also impressing during the opening laps in Portimao.

Quartararo dropped back to sixth and Marquez caught the back of Mir's Suzuki as he slipped back following a promising beginning to the race.

Rins, who started in second, moved passed Pramac Racing's Zarco in a flash at Turn 13 to hit the front before Jack Miller and Miguel Oliveira - winner on home soil last year - crashed out.

Quartararo had ominously put a disappointing start behind him to apply the pressure, becoming the latest leader of the race with 17 laps to go.

Rins tried his best to cut the gap in second place but spun off 11 laps from the end at Turn 10 after Valentino Rossi had crashed out from 11th place.

Quartararo was in complete control when Rins spun and a second-placed Zarco hit the deck, with Ducati rider Bagnaia holding off Mir for second, having been back in 11th, as the early championship lead changed hands.

The first Miami Grand Prix will be staged next year after a 10-year deal was agreed for the race to be added to the Formula One calendar.

A new layout at Hard Rock Stadium complex in Miami Gardens will be the venue for the latest addition to the F1 schedule.

No date has been confirmed for the event, which will mark the first F1 race in Florida since back in 1959 and ensure there will be two in the United States from 2022.

The circuit will be 5.41 kilometres, featuring 19 corners, three straights and the possibility of three DRZ zones, with an estimated top speed of 320km/h in a complex that is the home of the Miami Dolphins.

F1 president and CEO Stefano Domenicali said: "We are thrilled to announce that Formula 1 will be racing in Miami beginning in 2022.

"The USA is a key growth market for us, and we are greatly encouraged by our growing reach in the US which will be further supported by this exciting second race.

"We will be working closely with the team from Hard Rock Stadium and the FIA to ensure the circuit delivers exciting racing but also leaves a positive and lasting contribution to the people in the local community.

"We are grateful to our fans, the Miami Gardens elected officials and the local tourism industry for their patience and support throughout this process.

"We are looking forward to bringing the greatest racing spectacle on the planet to Miami for the first time in our sport's history."

Tom Garfinkel, vice-chairman, president and CEO of Hard Rock Stadium said: “The Hard Rock Stadium entertainment campus in Miami Gardens exists to host the biggest global events to benefit the entire greater Miami region and Formula 1 racing is as big as it gets.

"We have worked with specialist designers to create a racetrack that we, Formula 1 and the FIA believe will provide great racing and we hope to create best-in-class unique fan experiences that are reflective of the diverse and dynamic nature of Miami.

"I want to thank Formula 1 and the Miami Gardens and Miami Dade County elected officials for working to bring this hugely impactful event here for years to come."

Steve Kerr was "in awe" of the quality on show in an NBA thriller between his Golden State Warriors side and the in-form Boston Celtics.

The Celtics extended their winning run to six games with a 119-114 victory at TD Garden on Saturday despite being 16 points down in the first half.

Steph Curry's 47-point haul could not prevent Boston from coming out on top in a pulsating contest, with Jayson Tatum scoring 44 points and claiming 10 rebounds.

Kemba Walker weighed in with 26 points for the Celtics, who are 31-26 and sit fourth in the Eastern Conference.

Warriors head coach Kerr said: "First of all, I'm in awe of what I watched tonight.

"From a skill level and level of competition, it felt like a playoff game out there. Both teams were just gassed and competed like crazy, and just incredible shot-making, particularly from Steph and Jayson.

"So, what a basketball game. It hurts to lose, but I told the team I feel like they got better tonight."

Tatum and Curry had a court-side conversation after the Celtics small forward spoke of his admiration for the Warriors legend.

He said when asked what the pair had discussed: "Just mutual respect. Obviously two big performances. I was glad that we got the win, but obviously he's one of the all-time greats.

"Just to earn his respect and get a win on the same night ... it was a good night."

Golden State are 28-29 following this setback, languishing down in ninth in the Western Conference.

Andre Drummond is itching to experience more of the thrills of a home-court win with the Los Angeles Lakers after helping see out an overtime victory against the Utah Jazz.

Acquired at the end of March, Drummond found out for the first time how it felt to earn a win at the Staples Center as a Lakers player, as around 1,700 fans saw Los Angeles earn a 127-115 overtime triumph over the NBA Western Conference leaders.

The Lakers had previously seen a 14-point advantage evaporate, with the Jazz taking the lead towards the end of the fourth quarter, before Dennis Schroder tied things up with three seconds to play.

Still without the injured LeBron James and Anthony Davis, Drummond finished with 27 points, eight rebounds and three assists to aid the team's cause, while the impressive Schroder had 25 points, eight assists and six rebounds.

Since joining the Lakers, Drummond is averaging 9.2 points, 1.2 assists and 9.2 rebounds and he feels the depleted Lakers – fifth in the Western Conference – are beginning to gel.

"With the fans being in the arena it was kind of a surreal moment for me because I've been on the other side," he said. 

"Seeing them win, seeing the streamers come down, to be on this end it was definitely a great feeling and something I want more of.

"I think tonight was a good game for all of us, for me personally I think it was a pretty solid game. 

"As a unit we clicked on all cylinders. We didn't allow adversity to get us out of our game, they did have a hell of a run down the stretch to tie up the game and take the lead. 

"The chemistry is getting there, we're having fun day by day doing it."

Head coach Frank Vogel was impressed by the way his Lakers side kept their cool after seeing their lead wiped out.

"We made more in-game adjustments than we have all year just to counter their attack," Lakers Vogel said. 

"To have a team storm back and take the lead and [us] not panic is definitely something we can draw on going forward. We'll have this experience to know that we’ll prevail."

Mookie Betts pulled off a spectacular outfield catch to seal victory for the Los Angeles Dodgers in a 2-0 win over the San Diego Padres in MLB on Saturday night.

The 28-year-old center fielder dived to his left for Tommy Pham's curving hit, getting it inch-perfect for a walk-off catch in the ninth.

Dodgers manager Dave Roberts said: "Mookie has played a lot of innings in center field, but with that said, it takes an elite defender in center to make that play."

In a blockbuster tussle, Clayton Kershaw was crucial for the Dodgers with eight strikeouts across six innings, while Padres pitcher Yu Darvish had nine.

Earlier, Justin Turner hit a ninth inning home run to open up the 2-0 buffer, following Zach McKinstry's fifth inning run.

The result improves the Dodgers' 2021 record to 13-2, while the Padres are 9-7.

De Grom within a whisker of record

New York Mets right-hander Jacob de Grom came within one of Tom Seaver's 51-year-old record for consecutive strikeouts in their 4-3 win over the Colorado Rapids in the first game of their double-header.

De Grom finished the game with 14 strikeouts although the Mets lost the second of their double-header, going down 7-2.

Jorge Alfaro was the hero as the Miami Marlins scored twice at the bottom of the 10th to claim a dramatic 7-6 win over the San Francisco Giants.

Salvatore Perez came up trumps with a monster home-run at the bottom of the seventh to secure the Kansas City Royals a 3-2 walk-off win over the Toronto Blue Jays in the second of their double-header.

The win lifts the Royals to a 8-5 record, while the Blue Jays are 7-8.

The Oakland Athletics won their seventh straight, knocking off the Detroit Tigers 7-0, while the Boston Red Sox beat the Chicago White Sox 7-4.

The Tampa Bay Rays won 6-3 over the New York Yankees despite a bizarre moment when Tyer Glasnow's right leg and left hand suddenly cramped up.

Braves cop six home-runs

The Atlanta Braves saw six home-runs sail over their heads in their 13-4 loss to the Chicago Cubs, struggling on the mound, trying five different pitches on a rough night.

Greinke's double play

Houston Astros pitcher Zach Greinke pulled off an unusual 1-5-6 double play in their 1-0 win over the Seattle Mariners after dropping a red hot drive.

Dodgers in San Diego

The rivalry resumes between the San Diego Padres and the Los Angeles Dodgers on Sunday, with tempers spilling over at times during their series already.
