Holger Rune advanced to the Hamburg Open quarter-finals on Thursday as he looks to move on swiftly from his Wimbledon disappointment.

Rune's All England Club campaign was ruthlessly ended by Novak Djokovic in the fourth round, beaten in straight sets by the eventual finalist.

The Dane gave himself little time to lick his wounds and has quickly returned to the court and returned to form with his debut in Hamburg.

Looking for his first ATP Tour title of the year, the second seed followed up a straight-sets win over Fabian Marozsan by defeating Marco Trungelliti 6-4 6-3.

"It's been very intense since Wimbledon," Rune said. "I only had one day off, actually.

"I was like, 'I don’t want to rest, I want to go straight back to practice', because I was very disappointed.

"I went straight back to work on the things that needed to be done, and now I have the chance to train those things in matches."

Next up will be Arthur Fils, who booked his last-eight place by beating 2023 Hamburg finalist Laslo Djere 7-6 (7-3) 6-2.

Top seed Alexander Zverev remains a threat in the top half of the draw, however, and he will face Zhang Zhizhen in the quarters.

Andy Murray fumed at the umpire as inclement weather forced his Geneva Open tie with Yannick Hanfmann to be suspended.

Murray's meeting with Hanfmann was postponed with the Scot a set and a double break down, with his German opponent in control at 7-5 4-1.

Former world number one Murray was furious with umpire Greg Allensworth as the weather closed in.

"I know you guys don't play but it'd be good to have a bit of a feel for what's happening," said Murray during a break in play.

"You're fine for us to play when there's s*** flying around?

"It's like it's snowing out here and you still want us to keep going."

Allensworth eventually sent the players into the dressing rooms.

Murray is aiming to use the Geneva Open to prepare for what is set to be his first French Open appearance since 2020.

A tie with Novak Djokovic is on the cards if Murray can turn things around on Tuesday, though it looks incredibly unlikely.

Rafael Nadal's French Open haul is the only record in sport that will never be broken, according to Richard Krajicek.

And the former Wimbledon champion believes Nadal could yet add a 15th Roland Garros title in what is set to be his final year on the circuit.

Indeed, Krajicek believes Nadal's great rival Novak Djokovic would even be hoping to see the Spaniard succeed again in Paris.

While Djokovic's 24 singles grand slam triumphs edge out Nadal's 22, his performances at the clay-court major are unmatched.

Nadal has 14 French Open titles, losing only three times in 115 matches at the event.

Although he did not compete last year, as Djokovic earned his third Roland Garros championship, a winning return in 2024 would provide a fitting conclusion to a legendary career.

"It would be great for Nadal to go for the clay and win one more French Open," Krajicek told Stats Perform.

"I think every record in sports or in tennis can and will probably be broken. I'm pretty sure the only one that will never be broken is the 14 French Open titles from Rafael Nadal. I don't see how somebody can win 14 titles."

Of the possibility of one last win for Nadal, Krajicek added: "It would be just incredible.

"I think everybody in tennis, probably including his competition, Djokovic or [Carlos] Alcaraz, would love for Rafa to win one more French Open."

That is a realistic aim, according to Krajicek, although he does not see Nadal competing for the top prize at either Wimbledon or the US Open.

"For me, [the French Open] is the only one. If he wins any grand slam, it's that one," the 1996 All England Club winner said. "I don't think he'll ever win Wimbledon again, also not the US Open.

"I don't know how good his body is, but the feeling and how much he played or how little he played... I think, for me, only the French Open. Roland Garros is the only one he can win."

Asked for his reflections on Nadal's legacy, Krajicek replied: "I think his legacy will be of a great champion, number two in grand slams, so one of the greatest ever, unbelievable.

"A great person, humble person, and probably the biggest fighter we've ever seen in any sports arena, in any sport. Just an incredibly mentally strong athlete."

Jack Draper will bid for a first ATP Tour title at the Adelaide International after beating Alexander Bublik in the semi-finals.

The British number four saw off the eccentric Kazakh 7-6 (2) 6-4 to go one better than last year when he fell in the last four.

It represents a second straight ATP Tour final for the 22-year-old, who was beaten by Adrian Mannarino in the trophy decider at the Sofia Open in November.

Draper was twice a break up in the opening set against Bublik, who is one of the most unconventional players on tour.

He dragged Draper around the court with repeated drop shots and one game in the second set featured a rally where both players played lobs between their legs before Bublik sent over an underarm serve and won the point with a volley played with his racket handle.

But there were also nine double faults and a host of unforced errors and Draper maintained his high level to set up a final meeting with Czech Jiri Lehecka.

“It was a really tricky match,” said Draper. “Alexander’s a great player and someone who’s a very unorthodox player. It’s always tricky to play against him.

“He’s actually a really good guy and a good friend as well. We have a lot of fun when we’re competing against each other. I was really happy that I was able to come through and get the win today and be in another final.”

Victory for Draper on Saturday would elevate his ranking back into the top 50 ahead of his Australian Open opener next week.

Andy Murray will leave a lasting legacy on British tennis after his "historic" Wimbledon exploits when retirement eventually comes, according to Marion Bartoli.

Murray and Bartoli both triumphed at Wimbledon in 2013, the Scot defeating Novak Djokovic in straight sets and the Frenchwomen overcoming Sabine Lisicki.

A troublesome hip injury and subsequent surgery has caused issues in recent years for Murray, who also lifted the Wimbledon title in 2016 – adding to his US Open crown four years earlier.

The 36-year-old confirmed before the Queen's Championship last month that he has a period in mind for ending his professional career, leading Bartoli to hail Murray's impact on the sport.

"It's more for British tennis because the buzz when he won Wimbledon in 2013 for the first time was just insane – basically the whole country tuning in to watch that match," she told Stats Perform.

"Even the whole press, who are normally quite harsh with the players, especially the tabloids, were just cheering on for him because it was so historic.

"I can just remember the dinner we had at the Champions' Ball with Andy and his mother and my father and myself and it just felt like dinner with a mother and son, father and daughter, just being on the top of the world and just winning.

"Judy could say 'My son just won Wimbledon' and my dad could say 'My daughter just won Wimbledon' – it was very much that feeling. It was so special."

Murray, who has won two ATP Challenger titles this season, only made it as far as the second round at Wimbledon this month, losing to Stefanos Tsitsipas in a battling display on Centre Court.

His appearance at the British major represented another major milestone nevertheless, given injuries seemed set to curtail his playing days after the 2023 Australian Open.

Bartoli added: "For Andy, after all his surgeries and everything, it's about how much he can still enjoy his tennis.

"When he feels that's it, that every day on the practice court is not as enjoyable as usual, and he's dragging himself to practice, that’s when the passion is vanishing and you know it's time [to retire].

"It's not that difficult of a decision when that happens. When you still have that passion and fire but your body doesn't follow anymore, then it's slightly more difficult.

"In many ways, Andy had a second chance. He'd sort of announced his retirement when he lost in the Australian Open and everyone was crying.

"Then he decided to come back and he had those successes and those great matches and epics, so maybe he already feels like he had his second chance.

"He'll walk away with a beautiful family, a business – a hotel, I think, in Scotland where he grew up – so he has so many things to look forward to. I think he'll be a very happy man."

Murray's diminishing influence on the upper echelons of tennis marks a downturn in British fortunes, with Cameron Norrie seemingly the next in line.

"For the British side of tennis – you have Cameron Norrie – but you feel that especially with [Carlos] Alcaraz coming in and all those players it's going to be more difficult to win a slam," Bartoli continued.

"But he's going to have his chance as well. He's close to being top 10."

Novak Djokovic will remain a force at the top of men's tennis despite the disruption to his dominance that has been caused by Carlos Alcaraz.

That is the view of former Wimbledon champion Marion Bartoli after the Serbian missed out on a fifth consecutive title, which would have been a record-equalling eighth overall, at the All England Club on Sunday.

Roared on by the Centre Court crowd, Alcaraz produced a dynamic performance in the final to earn a spirited five-set victory, storming back to win having lost the first set 6-1.

Despite only just turning 20, the Spaniard now has two grand slam titles to his name, having won the US Open last year.

And it is in New York where Djokovic will look to respond to only his second loss in nine Wimbledon finals.

Despite Djokovic's setback, Bartoli is confident 23-time grand slam winner is primed to win multiple further majors and one day reach 25, saying the veteran remains the man to beat.

"As the champion it is never nice to lose for sure and it will sting for a few days," Bartoli said to Stats Perform.

"I don't think he's going to come out of this match like 'yeah, it's fine I just lost it', as you don't win 23 grand slams without being a fierce competitor and without hating to lose.

"But there is the US Open coming up this year, so there is a lot on the line for him.

"He has absolutely no points to defend [in the US Open] and then he has the year-end championship [ATP Finals] that he won at the end of last year. 

"On the other end Alcaraz has the US Open to defend so it's more than likely that Novak Djokovic will be able to regain that number one ranking spot at the end of the US summer swing.

"He's going to get himself ready for that. I'm not sure what kind of schedule he will play, whether he's going to play the two Masters events before or maybe just one and go to the US Open because he's 36 and you just can't have the same schedule as someone like Carlos Alcaraz has, that is obvious.

"But can he pass and go over Margaret Court [on 24 major titles]? Absolutely. He's going to be the favourite to win the US Open equally with Alcaraz and he will be the overall favourite to win the next Australian Open.

"So absolutely it is very much more than achievable for him [to pass Court] and obviously I think by the end of 2024 that's where he should stand — at least 25 Grand Slams and alone on top of the world."

Djokovic had not lost at Wimbledon since going down to Tomas Berdych in the 2017 quarter-finals and the final was his first loss on Centre Court for 10 years, since Andy Murray beat him in the famous 2013 final, the same year when Bartoli won on the women's side.

Bartoli added: "So for sure it's just going to sting for him when he looks back at those tapes and sees back those points that he missed – two backhands during the tie-break, the drop shot that he missed in the net at 3-2 for him in the breaker, sees the swing volley that he decided to actually take in the air – maybe just let it drop and see if the ball actually will stay in the court or not.

"It is just two or three crucial points here and there that made the whole result at the end of the match change. He had set point to go up two sets to love. I think if he covered there, it is completely different. 

"He had a break point at the beginning of the fifth to go 2-0 up after winning the fourth and was carrying the whole momentum with him, so he was extremely close."

Bartoli thinks the rise of Alcaraz epitomises the new style of modern players, but thinks Djokovic's complete game means he is still well-placed to mix it with rising stars.

Alcaraz is the youngest player in the Open Era to win the singles title at both the US Open and Wimbledon.

But asked if the win for Alcaraz was a changing of the guard, she replied: "No, but I felt it was a new tennis. 

"It was very much a sort of new complete tennis that we'll be able to witness from the new generation of players coming in. I include in that Holger Rune and Jannik Sinner as the same [style] as Alcaraz. 

"The defence is there, the court coverage is there, the speed is there, coming to the net is there, playing the dropshot is there, play aggressive and defensive, and they can last for whatever time is required on the court. And in some sort of way in the middle, there is Daniil Medvedev and Stefan Tsitsipas too.

"That's what the new tennis on the men's side is looking for. Maybe for the next 10 years or so. And I think very much Novak was up to the task [against Alcaraz].

"So I don't think it was a change of the guard. I just felt it was a new tennis and because Novak has that type of tennis obviously he can sustain that level." 

The epic Wimbledon final between Carlos Alcaraz and Novak Djokovic is among the best three tennis matches Marion Bartoli has ever seen.

Former Wimbledon champion Bartoli watched in awe as Alcaraz dethroned Djokovic at the All England Club on Sunday, coming from behind to win a classic contest 1-6 7-6 (8-6) 6-1 3-6 6-4.

Bartoli played in two Wimbledon finals herself and was commentating on the latest instalment of great showpiece battles on Centre Court as Djokovic was denied a record-equalling eighth title at the grand slam tournament.

"I definitely ranked it in the top three matches that I've ever seen," Bartoli told Stats Perform.

"Of course there are some finals I haven't seen especially from before [this era], but I think when you look at it as Roger [Federer] against Rafa [Nadal] at Wimbledon 2008, and then Rafa against Novak at Australian Open 2012 and then this one, you will very much have the top three matches ever played. That's my personal opinion. 

"Maybe some people will add two or three other matches, but it is 100 per cent in the top five without a doubt, and I think I could even put it top three." 

Djokovic was frustrated as the Centre Court crowd rooted for his younger opponent for much of a back-and-forth encounter.

But Bartoli thinks the 20-year-old Spaniard would command support against any player.

She stressed that Wimbledon great Djokovic still gets plenty of backing, and much of the crowd reaction in favour of Alcaraz would have been based on not wanting the match to end quickly as the sport's latest blockbuster rivalry begins.

Alcaraz became the first player not called Djokovic, Federer, Nadal or Andy Murray to triumph at Wimbledon since 2002 – before he was even born – and the British crowd were relishing his success.

"It seemed like there was such an affection for Carlos Alcaraz," Bartoli said.

"In terms of Carlos, I don't know if it's because he's won so many matches and he doesn't lose or maybe the crowd is naturally against Novak, but for me I think it's more of an admiration for Carlos.

"From what I'm seeing from the crowd it is more like when you have this new genius that comes around, everyone wants to be part of the journey. I very much feel that with him. 

"And it's around the world – the welcoming that he had at the US Open last year, look at the shouting from the crowd again in that incredible match against Jannik Sinner when he was really on the ropes and Sinner was leading all the way and just couldn't finish it out at the end. 

"I think it's more when you're recognising that there is someone that good, it's almost impossible not to be for him, unless he's playing a local player. 

"That will be interesting to see if he plays the Brits next year. What sort of Centre Court is it going to be then? But if it's against anyone else then for sure they are going to be on his side.

"But even then I feel Novak has been really getting some great support as well and I think very much the crowd wanted to have a five-set match or a long run. 

"They didn't want it [to end quickly] when Carlos lost the first set easily and when Carlos won the second set then they didn't want Carlos to run away with the match either. 

"They really wanted both players to go out for battle all out for four hours and 45 minutes just like they did, so I don't think it's going to be one-sided always for Carlos Alcaraz. 

"But everyone very much feels like he is really the new genius and everyone wants to see him." 

The loss for Djokovic was the first time he had been beaten in a five-set grand slam final since losing to Murray in the 2012 US Open.

Despite that, Djokovic overtook Chris Evert (34) as the player with the most appearances in major finals, among both men and women (35).

Wimbledon is over for another year.

The British grand slam brought with it plenty of twists and turns, not least in the men's singles final on Sunday, as Carlos Alcaraz overcame Novak Djokovic in a five-set thriller.

A day before Alcaraz sealed his second major title with that 1-6 7-6 (8-6) 6-1 3-6 6-4 success, Marketa Vondrousova won her first grand slam with a surprise 6-4 6-4 victory over Ons Jabeur.

Using Opta data, Stats Perform looks back at the best statistics from the last two weeks at the All England Club.

King Carlos

It looked like it might be a bad day at the office for Alcaraz when Djokovic cruised to a 6-1 win in the first set on Centre Court, but the Spaniard came back with a bang.

Alcaraz is an incredible talent that looks set to take up the mantle left by Rafael Nadal, and while Djokovic was at times at his dominant best, it still wasn't enough to down the world number one.

At 20, Alcaraz is the third-youngest player in the Open Era to win the men's singles title at Wimbledon, after Boris Becker and Bjorn Borg.

And he is now the youngest player in the Open Era to win the singles title at both the US Open and Wimbledon.

Nadal was the only previous Spaniard to win the coveted trophy, as Alcaraz became the first player not called Nadal, Djokovic, Roger Federer or Andy Murray to triumph at the All England Club since 2002 - before he was even born.

He became the first player to defeat three top-10 opponents en route to winning the Wimbledon title since Pete Sampras did so in 1994, while after claiming the title at Queen's, Alcaraz is the second-youngest player to win 12+ consecutive grass-court matches (Boris Becker was the youngest to achieve the feat, with 13 straight wins in 1985 between the Queen's Club and Wimbledon).

No Grand Slam for Novak

Djokovic became the second player in the Open Era to reach multiple men's singles grand slam finals in a single year after turning 36, after Ken Rosewall in 1974. He also overtook Chris Evert (34) as the player with the most appearances in major finals, among both men and women (35).

Only Federer, with 46, can match the Serbian's tally of grand slam semi-final appearances in the Open Era, meanwhile.

The 36-year-old also became just the third player in the Open Era, after Federer and Jimmy Connors, to play in 100 men's singles matches at Wimbledon.

Djokovic had not lost a five-set grand slam final since losing to Andy Murray in the 2012 US Open.

Indeed, Djokovic had not lost at Wimbledon since going down to Tomas Berdych in the 2017 quarter-finals and the final was his first loss on Centre Court for 10 years, since Murray beat him in the famous 2013 final.

Vondrousova victorious

Vondrousova is the first unseeded player to win the women's singles title at Wimbledon in the Open Era. It marked only her second career WTA Tour title, following her success at Biel in 2017.

She is the lowest-ranked player to win the singles title in Wimbledon since the WTA Rankings were introduced.

The Czech was playing in her second grand slam final, having previously lost to Ashleigh Barty at the 2019 French Open.

Vondrousova now holds a record of 3-2 head-to-head against Jabeur, with the latter winning their only previous meeting on grass, at Eastbourne in 2021. All the Tunisian's losses Vondrousova have come in 2023.

Vondrousova is the sixth unseeded player to win a grand slam title in the last decade, after Jelena Ostapenko, Sloane Stephens, Iga Swiatek, Barbora Krejcikova and Emma Raducanu.

The 24-year-old is the third Czech woman to win the singles title at Wimbledon, after Jana Novotna (1998) and Petra Kvitova (2011, 2014).

Meanwhile, Jabeur became the first player since Simona Halep to lose each of her first three singles finals at grand slams, while the 28-year-old is the third player in the 21st century to lose successive Wimbledon finals after Venus Williams (2002, 2003) and Serena Williams (2018, 2019).

Leading tennis players should speak out against "appalling" human rights abuses in Saudi Arabia as the Public Investment Fund (PIF) targets a partnership with the ATP Tour.

That is the view of Amnesty International's regional campaigner Reina Wehbi, who sees the prospective link as a way of distracting from the country's "crackdown" on basic rights. 

Earlier this week, ATP chairman Andrea Gaudenzi told The Financial Times that talks had been held over a partnership between the PIF and the men's tour. 

Saudi Arabia's numerous sports investments – including the PIF's majority ownership of Newcastle United and the controversial LIV Golf circuit – have been denounced by critics as efforts to improve the country's reputation through 'sportswashing'. 

Speaking exclusively to Stats Perform, Wehbi said tennis stars should not shy away from criticism of Saudi Arabia's record on human rights.

"Saudi Arabia is promoting its colossal investment in sporting events and entertainment as progress and reform. This is a far cry from its appalling human rights record," Wehbi said.

"Saudi Arabia's interest in the ATP fits into a wider pattern of sportswashing that the country has been using to divert attention from its escalated human rights violations.

"Authorities continue their crackdown on the rights to freedom of expression, association and assembly. Almost every single human rights defender has been unlawfully detained in Saudi Arabia. 

"Last year, Amnesty recorded the highest number of executions in 30 years in Saudi Arabia. Human rights should be a primary consideration when choosing where to host international sporting events and sporting bodies have the responsibility to undertake due diligence to identify and mitigate human rights violations directly linked to their events.

"Tennis players and all other celebrities should make sure to use their celebrity status and their popular platforms to speak up against abuses and be the voice of those put behind bars for exercising their rights.

"They should make sure not to offer Saudi Arabia uncritical praise and not to help it avoid scrutiny for its continued human rights violations behind the scenes. 

"All players should advocate for the respect and protection of human rights wherever they are."

Gilles Simon believes Andy Murray's inferior trophy haul means he cannot be grouped with tennis' 'Big Three' of Novak Djokovic, Rafael Nadal and Roger Federer.

Murray has enjoyed a long and stellar career, reaching 11 major finals and claiming three grand slam titles, as well as spending 41 weeks ranked as the world number one.

But with Djokovic, Nadal and Federer boasting 23, 22 and 20 grand slam successes respectively, Simon feels Murray is not quite on their level.

"He's not part of the Big Three," Simon told Stats Perform at the Roland-Garros eSeries by BNP Paribas. 

"You don't have to compare him with the Big Three, because he played at the very same time and we have the result.

"Andy was a fantastic player, just under these three guys in terms of level. In the end, the gap is huge in terms of titles: 23, 22 and 20, compared to three, so he's not part of the Big Four.

"He played at the same time as everyone and he has three and they have 20 or more. That's how I see it."

Simon – who won three of his 19 meetings with Murray before retiring in 2022 – feels the Scot was unfortunate to have competed with the 'Big Three' and would have been remembered as one of the game's greats in another era.

"He could have won 17 slams without the Big Three," Simon explained. "What is hard for Andy is to compare him to other players from other generations, when other players maybe have more slams than he has.

"If he had played at that time, he could maybe have had 15 and been one of the greatest. You cannot compare him with the Big Three, we saw it already, we saw the results.

"Where I feel sad for Andy is that if you play in a different era, you have 10 [grand slam titles] and then if we take the all-time rankings, we go to [Pete] Sampras with 14 and you say maybe he's here.

"This is where I feel it's a bit of an injustice for him compared to his level, because he would be closer to something like this than to someone who has three slams. He would be much higher in the all-time rankings."

Rafael Nadal will be contemplating the best way to call time on his stellar career after injury denied him the chance to defend his French Open title, believes Tommy Haas.

Nadal has not played since suffering a second-round exit at the Australian Open in January, having struggled with a hip injury during his straight-sets defeat to Mackenzie McDonald.

The 22-time grand slam champion last week admitted defeat in his bid to appear at Roland Garros, where he has triumphed 14 times – a record for any player at a single grand slam.

When announcing his withdrawal, Nadal said 2024 would "probably" be his final year on the ATP tour and outlined his intention of making farewell appearances at "important tournaments".

Nadal's long-time rival Roger Federer retired surrounded by several of his fellow greats at last year's Laver Cup, and Haas believes the Spaniard will be eyeing a similar send-off. 

"At some point, time catches up with all of us and that's the reality," Haas, a four-time grand slam semi-finalist, told Stats Perform.

"I think at this stage, I'm sure he's been contemplating the idea: 'When would I do it? How would I do it? How would it come together organically?' 

"We saw Roger Federer doing it last year and the way he was able to retire in London at the Laver Cup with all of his rivals and friends on the court. I happened to be there live, it was an amazing way to finish such an incredible career. 

"Look at Pete Sampras. He won his first slam at the US Open and he won his last match at the US Open, winning the slam there on home turf – there couldn't have been a better fairy tale. 

"I think you look at that and at the same time, you have to stay focused on what's happening today and you can't look too far ahead."

Though Nadal's total of 22 grand slam singles titles is a joint record in the men's game (alongside Novak Djokovic), the Spaniard's injury record has denied him several chances to add to that tally.

Nadal played all four grand slams for the first time since 2019 last year but was forced to withdraw from the Wimbledon semi-finals, and Haas says the Spaniard's fitness will dictate his future.   

"It always depends, obviously, on the injuries. 'How bad is it and can I recover from it?' I'm sure Rafa is constantly thinking about those situations," Haas added.

"He's been saying he still wants to play for another year or two, which would obviously be amazing for the sport. 

"On clay, I think he has a better chance of keeping the body in a better shape than on gruelling hardcourts. He obviously plays long matches, which is tough on the body."

The main draw of the French Open begins on Sunday, with Nadal's compatriot Carlos Alcaraz the top male seed as he bids for a second major title.

Defending champion Carlos Alcaraz made light work of Grigor Dimitrov to cruise into the last 16 of the Madrid Open with a straight-sets win on Sunday.

The Spaniard thrilled the home crowd at Caja Magica to reach the fourth round in style with a 6-2 7-5 victory.

Dimitrov lost his serve twice in a ruthless first-set rout and could not mount a comeback despite a spirited attempted recovery against the world number two.

Alcaraz's victory sets up a fascinating fourth-round clash with Alexander Zverev in a repeat of last year's final.

Zverev himself secured fast passage from the third round with a 6-1 6-0 win over Hugo Grenier.

Alcaraz and Zverev are joined in the last 16 by Andrey Rublev and Karen Khachanov after their respective victories against Yoshihito Nishioka and Roberto Bautista Agut.

There is no place for 12th seed Hubert Hurkacz, however, after he fell to a 7-6 (7-3) 6-3 loss against Borna Coric.

Carlos Alcaraz survived a major scare in the opening match of his Madrid Open title defence as he came from behind to beat Emil Ruusuvuori.

The defending champion, who defeated Alexander Zverev in last year's final, was twice broken in the opening set by Ruusuvuori but responded well to prevail 2-6 6-4 6-2.

Alcaraz hit 36 winners to his opponent's 23 to reach the last 32, where Grigor Dimitrov awaits after defeating Gregoire Barrere 7-6 (8-6) 7-6 (7-2). 

"It was really tough. I would say I was about to lose," Alcaraz said in his on-court interview. "It was really tough. Emil played unbelievably, but I am really happy to get through that."

There was a shock result elsewhere as third seed Casper Ruud lost 6-3 6-4 to Matteo Arnaldi, who had never previously claimed victory over a top-10 opponent.

Arnaldi previously eliminated Benoit Paire and will now take on Jaume Munar – the Spaniard advancing after Tallon Griekspoor retired when a set behind in their second-round tie.

Monte Carlo Masters winner Andrey Rublev continued his good form on the clay courts with a 7-5 6-4 win against Stan Wawrinka.

Dominic Thiem cruised through the first round of the Madrid Open in straight sets on Thursday, while former winner Andy Murray suffered an early exit.

Thiem, who has twice finished as runner-up at this event, made short work of Britain's Kyle Edmund in a 6-4 6-1 win to set up a second-round meeting with fourth seed Stefanos Tsitsipas.

The Austrian won 86 per cent of points on his first serve (24 of 28) and saved all four break points against him as Edmund just could not get himself into the contest.

Elsewhere, Murray, who claimed titles in Madrid in 2008 and 2015, could not embark on another such run, with the veteran dispatched by Andrea Vavassori in a 6-2 7-6 (9-7) defeat.

The Italian was particularly dominant at the net against Murray, winning 13 of 17 such points, while the 35-year-old managed just five of 14.

Qualifier Roman Safiullin saw off a fightback from Chile Open winner Nicolas Jarry to progress 6-2 3-6 6-3, setting up a clash with Tommy Paul in the second round, while Dusan Lajovic followed up his win at the Srpska Open by beating Jason Kubler 6-3 6-3. 

Stan Wawrinka recovered from a set behind to overcome Maxime Cressy and set up a second-round showdown with Andrey Rublev at the Madrid Open.

Three-time grand slam winner Wawrinka, who is the oldest player in the main draw, hit back in the Spanish capital to progress 6-7 (7-3) 6-3 7-6 (7-4).

The 38-year-old won 46 of 54 first-serve points and now has a couple of days to recover before facing fifth seed Rublev, who was handed a bye to the last 32.

Roberto Carballes Baena is also through after defeating David Goffin 6-4 6-4, with Alexander Zverev up next, while Alex Molcan saw off Wu Yibing 6-2 6-4.

There was a shock elsewhere on Wednesday as Diego Schwartzman was downed in straight sets by Hugo Grenier.
