Kei Nishikori's comeback surprised the former world number four, who survived a major scare to advance at the Barcelona Open.

Nishikori trailed 6-4 4-2 and was forced to break serve as Guido Pella attempted to close out the match in the second set, before sensationally rallying to a 4-6 7-6 (7-4) 6-2 win on Monday.

A two-time champion at the ATP 500 tournament on the Barcelona clay, Nishikori broke serve on three occasions in the final set en route to the second round.

"He had the match today at 6-5, serving [for the match]," said Nishikori. "He was much better in the first and second [sets] and 3-0 up in the tie-break. I don't know how I fought through. [In the] third set, I was playing much better.

"I was making so many unforced errors in the first and second [sets]. Maybe he got a little bit tired and I was playing strong in the third set. I want to take that to the next round… The way I fought today and the way I played in the third set was good."

Next up for 2014 US Open finalist Nishikori is 13th seed Cristian Garin.

Ilya Ivashka topped Tallon Griekspoor 6-3 6-1 and the qualifier's reward is a showdown with top seed and 20-time grand slam champion Rafael Nadal.

Cameron Norrie, Pablo Andujar, Jeremy Chardy, Pierre-Hugues Herbert, Jaume Munar, Federico Gaio, Egor Gerasimov and Bernabe Zapata Miralles all advanced to the last 32.

At the Serbia Open, seeds Filip Krajinovic and John Millman booked their spots in the round of 16.

With the ATP 250 tournament being staged for the first time since 2012 and headlined by world number one Novak Djokovic, Serbian fifth seed Krajinovic overcame Stefano Travaglia 7-5 5-7 6-3 in a Belgrade rollercoaster.

Millman – the Australian seventh seed – took down local wildcard Danilo Petrovic 7-5 6-4 as Marco Cecchinato and Nikola Milojevic won through.

Stephen Curry has been lighting it up in the NBA of late.

The two-time NBA MVP is seemingly trying to make up for lost time after injury wiped out the vast majority of his 2019-20 season. 

However, Curry is not the only player in prime form. As the regular season hurtles towards a conclusion, Stats Perform data highlights who is on fire and who needs to find a spark around the league.

Time to dip into the numbers with the latest edition of Heat Check...

RUNNING HOT...

Stephen Curry

To say Curry is on a hot streak is an understatement. In four games between April 12-17, the guard scored 175 points for the Golden State Warriors. That astonishing scoring run saw him hit 10 or more three-point attempts in three of those outings; no other player in NBA history has had three or more such games in an entire season, let alone a week.

Luguentz Dort

Dort was averaging 12.62 points heading into the week. The second-year guard then upped that number with 42 against the Utah Jazz and while he sat out a game against the Warriors, he followed up with a combined tally of 55 when facing the Detroit Pistons and Toronto Raptors. Despite his scoring heroics, the Oklahoma City Thunder lost all three.

Landry Shamet

The Brooklyn Nets have been hampered by injuries this season, with James Harden sidelined in recent times. However, Shamet has stepped up to help fill the void, managing a career-high 30 points on Sunday against the Miami Heat, including tying a franchise record with seven successful three-point attempts having come off the bench. 

GOING COLD...

Lonzo Ball

Ball's decreased production should come as no surprise, considering he is easing his way back into action following a hip injury. He played just under 20 minutes against the Washington Wizards and while his involvement was greater against the New York Knicks, 2017's second overall pick managed nine points from 19 shot attempts across both games.

Tyler Herro

A low-key week for Herro, who failed to reach double digits for points in outings against the Denver Nuggets, Minnesota Timberwolves and Nets. The shooting guard - such a key figure in the Heat's run to the NBA Finals in the 2019-20 season - landed two of his 11 attempts from beyond the arc in those games. Surprisingly for someone based in Miami, Herro has gone cold.

Chris Paul

The veteran point guard has been outstanding for the Phoenix Suns, who remain in the running to finish the regular season as the top seeds in the West. However, the bigger picture means minutes must be managed, with Paul seeing a drop in his workload. While buckets have been in short supply - he averaged 8.25 points per game across last week - there were still 26 assists.

Belinda Bencic claimed her first win on clay since the 2019 French Open as she saw off teenager Nastasja Schunk at the Stuttgart Open.

The world number 12 eased to a 6-4 6-2 victory over the 17-year-old qualifier, who saved five match points in her final service game before Bencic closed things out.

"My love affair with clay is... I'm trying to improve myself on it," Bencic said after her first-round triumph.

"I think I'm getting better and I'm taking falls sometimes. I'm trying my best on this surface."

Maria Sakkari was similarly comfortable in progressing to the next round, hitting 24 winners as she dispatched Andrea Petkovic 6-2 6-2 on her debut at the tournament.

At the Istanbul Cup, four of the five scheduled matches were completed before rain stopped play with Anastasia Pavlyuchenkova and Anastasia Potapova level at a set apiece.

Eighth seed Wang Qiang fought back from a set down to beat Anastasia Gasanova 4-6 6-1 6-2.

There were also wins for Ana Konjuh, Katerina Siniakova and Viktorija Golubic.

Bam Adebayo was backed to "hit another level" after his buzzer-beater snatched a 109-107 victory for the Miami Heat over the Brooklyn Nets on Sunday.

Adebayo stepped up to inspire the Heat at the AmericanAirlines Arena to a thrilling win in the absence of Jimmy Butler, who was ruled out with a sprained ankle.

The 23-year-old centre settled a pulsating contest when he took a pass from Goran Dragic with time almost up and was on target with a baseline jumper from around 12 yards out.

Adebayo finished with 21 points, 15 rebounds, five assists and two steals in a brilliant all-round performance against a 38-19 Nets side occupying second place in the Eastern Conference.

Dragic said of Adebayo: "He has great potential. I still feel he's not done yet. He's going to hit another level."

The Heat are seventh in the Eastern Conference and Adebayo believes they can put a run together following such a dramatic win.

He said: "A season can turn around after a game. Crazier things have happened in this league."

Heat coach Erik Spoelstra says Adebayo's all-round contribution should be recognised.

He said: "It's just not about scoring. That's the hard thing in this league, that the main thing people look at is how many points people score.

"Bam has so many things that he does for us that are important for us to be successful."

The Nets also lost Kevin Durant in the opening quarter due to a left thigh contusion.

Julius Randle produced another inspiring performance as the streaking New York Knicks topped the New Orleans Pelicans 122-112 in overtime.

Knicks All-Star Randle posted 33 points and 10 assists to lead the New York franchise to their sixth successive NBA win on Sunday.

Randle recorded his fourth consecutive game with at least 30 points, becoming the first Knicks player since Carmelo Anthony in 2014 to accomplish the feat.

Reggie Bullock nailed a three-pointer for the Knicks with 2.3 seconds remaining in regulation before the home team outscored Zion Williamson's Pelicans 19-9 in OT at Madison Square Garden.

Derrick Rose scored a season-high 23 points for the Knicks, who are in the midst of their longest winning streak since 2013-14 as they eye their first playoff appearance since 2013.

Williamson's 34 points, nine rebounds, five assists and two steals were not enough for the visiting Pelicans.

Meanwhile, Kevin Durant suffered a left thigh contusion in the Brooklyn Nets' 109-107 loss away to the Miami Heat.

Durant – who only returned from a 23-game injury absence this month – left the game in the opening quarter, having gone three-for-three shooting to finish with eight points in four minutes.

Bam Adebayo (21 points and 15 rebounds) lifted the Heat with his buzzer-beating jump shot.

Hawks soar past Pacers

Clint Capela (25 points and 24 rebounds) and Trae Young (34 points and 11 assists) helped the Atlanta Hawks power to a 129-117 victory against the Indiana Pacers. Bogdan Bogdanovic and Kevin Huerter contributed 23 points each for the Hawks, who have won eight of 10 games and are 17-6 under interim head coach Nate McMillan.

Kawhi Leonard returned from a four-game absence, tallying 15 points, 11 rebounds and eight assists in the Los Angeles Clippers' 124-105 success at home to the Minnesota Timberwolves.

Chris Boucher put up 31 points and 11 rebounds for the Toronto Raptors, who downed the lowly Oklahoma City Thunder 112-106 for a third consecutive win. Oklahoma City's Aleksej Pokusevski (six) became the first Thunder rookie with five-plus blocks in a game since Serge Ibaka in 2010.

The Charlotte Hornets snapped a four-game skid behind Terry Rozier as his 34 points, 10 assists and eight rebounds saw off the Portland Trail Blazers 109-101.

De'Aaron Fox's 30 points and 12 assists guided the Sacramento Kings to a 121-107 win over the Dallas Mavericks. Dallas All-Star Luka Doncic finished with a game-high 37 points.

Thunder continue to be silenced

The Thunder are now in the midst of a season-worst losing streak of 10 games after losing to the Raptors.

Josh Richardson struggled again for the Mavericks. He was just three-for-nine shooting, while making only one of his five three-point attempts for seven pints. Mavericks team-mate Tim Hardaway Jr. (eight points) finishing two-for-10 shooting.

Bridges goes bang!

Miles Bridges is becoming known for his slam dunks. The Hornets star produced another memorable dunk in the second quarter.

Sunday's results

Atlanta Hawks 129-117 Indiana Pacers

Warriors at 76ers

Red-hot Stephen Curry and the Golden State Warriors (28-29) visit the Eastern Conference-leading Philadelphia 76ers (39-17) on Monday. The 76ers have won four straight games.

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.
