Jannik Sinner has joined Carlos Alcaraz in withdrawing from the Italian Open due to injury.

Sinner, who pulled out of his quarter-final tie with Felix Auger-Aliassime at the Madrid Open this week, is suffering with a hip issue.

It means the world number two will not participate in what would have been a home tournament in Rome, in what is sure to be a disappointment to the Italian fans.

"It is not easy to write this message but after speaking again with the doctors and specialists about my hip problems I have to announce that unfortunately I will not be able to play in Rome," he wrote on X.

"Obviously I'm very sad that I didn't recover, it being one of my favourite tournaments ever. I couldn't wait to come back and play at home in front of the Italian crowd."

Sinner added he was focusing on recovering in time to play at the French Open, which starts towards the end of May.

On Friday, world number one Alcaraz withdrew from the Italian Open due to an arm problem.

Carlos Alcaraz has withdrawn from next week's Italian Open due to the arm injury that troubled him at the Madrid Open, where Andrey Rublev and Felix Auger Aliassime will face off in Sunday's final.

Alcaraz saw his bid for a third successive Madrid Open crown halted by Rublev in the quarter-finals on Wednesday, the Spaniard being pegged back after taking the opening set in a 4-6 6-3 6-2 loss.

The two-time grand slam champion – who had won his previous 24 matches at Spanish clay-court events – looked tired throughout that match and has now withdrawn from next week's ATP 1000 Masters event in Rome.

In a post to X, Alcaraz wrote: "I felt pain after playing in Madrid, discomfort in my arm. 

"Today I had some tests and I have muscle edema in the pronator teres, a consequence of my last injury. Unfortunately I won't be able to play in Rome. I need rest to recover and be able to play 100 per cent pain-free." 

Alcaraz only has limited time to recover if he is to feature at the year's second major, with the French Open due to begin on May 20.

Alcaraz's conqueror Rublev advanced to the final of the Madrid event on Friday, producing a commanding performance to beat American Taylor Fritz 6-4 6-3 in the last four.

Rublev entered the Madrid Open on a run of four straight losses, but he is now into his third ATP Masters 1000 final since the start of 2023 – a tally only bettered by Alcaraz and Daniil Medvedev (four apiece).

His opponent in Sunday's showpiece match will be Auger Aliassime, who progressed by virtue of a walkover on Friday after semi-final opponent Jiri Lehecka was forced to retire through injury.

Lehecka left the court for treatment on a back injury after just six games, with Auger Aliassime having held serve for 3-3. He only managed to play three further points on his return before calling the match to a halt in a disappointing ending to the night session.

Data Debrief: Lucky Auger Aliassime

Auger Aliassime would surely have preferred to win his semi-final the traditional way, but the Canadian should be fresh for Sunday's final after spending very limited time on court.

He has progressed through three rounds at this year's Madrid Open courtesy of a retirement or walkover, with Jakub Mensik and Jannik Sinner also stricken.

He is the first player since 1990 to progress through three rounds via retirement or walkover at a single ATP Masters event.

Carlos Alcaraz saw his hopes of a third straight Madrid Open crown dashed on Wednesday, as Andrey Rublev fought back to seal a statement quarter-final win over the defending champion.

Alcaraz had been pushed close in the last 16 by Jan-Lennard Struff on Tuesday, requiring two tie-breaks to see off the German in three sets, and those exertions seemed to take their toll as he produced a below-par display on Wednesday.

Seven unforced errors from Rublev helped the home favourite take the opener, but he appeared to tire from there as his seventh-seeded opponent fired in 27 winners in a 4-6 6-3 6-2 victory.

Rublev broke Alcaraz's serve in the first and fifth games of the decider, also serving impressively to deny the Spaniard a single break point after a nervous first hold. 

Alcaraz's exit ended home interest in the tournament, just one day after five-time champion Rafael Nadal was dumped out in the last 16 by Jiri Lehecka.

Speaking to Sky Sports Tennis, Rublev said: "I can't believe that I was able to stay calm throughout the match. I didn't say a word and even I'm impressed by that!

"I want to believe that I have been working on this because if not, then I'm stupid. I just thought to myself to keep trying, keep fighting, keep believing in yourself."

Data Debrief: Major scalp for Rublev

To say Rublev entered Wednesday's match as the underdog would be an understatement. Alcaraz was looking to become the first player to win three straight Madrid Open singles titles, and was 24-0 in Spanish clay-court events since the start of 2022.

Rublev, though, was not overawed by the occasion and punished a sluggish performance from the world number three. Wednesday's win was his first over a top-three opponent since 2022, and he will now face either Taylor Fritz or Francisco Cerundolo in the last four.

Jan-Lennard Struff made life difficult for Carlos Alcaraz, but the reigning Madrid Champion eventually made it through.

Alcaraz had won both of his opening games with the minimum of fuss, but he needed three sets to get beyond Struff, who won a second-set tie-break.

However, Alcaraz eventually prevailed in the decider, clinching a 6-3 6-7 (5-7) 7-6 (7-4) victory.

Alcaraz, who is in the hunt for a third straight title in Madrid, will now face seventh-seed Andrey Rublev for a place in the last four.

Data Debrief: Prodigal son matches the master

There have been plenty of comparisons between Alcaraz and his fellow Spaniard Rafael Nadal.

And with his win on Tuesday, Alcaraz matched Nadal's record for the longest winning run at the Madrid Open, at 14 matches, since the tournament began in 2002.

Carlos Alcaraz boosted his hopes of a third straight Madrid Open title as he comfortably beat Thiago Seyboth Wild to reach the fourth round on Sunday.

Back in his home country of Spain, Alcaraz eased to a 6-3 6-3 triumph to set up a fourth-round clash with Jan-Lennard Struff, whom he beat in last year's final.

The first six games of the opening set went to serve, but Alcaraz found a crucial break in the seventh and ninth games of the set to put him in pole position for victory, a lead he would not relinquish as he overcame being broken in the seventh game of the second set to seal his safe progression.

Holger Rune was a surprise casualty as the world number 12 was defeated 6-4 4-6 6-3 by Tallon Griekspoor, though world number eight Andrey Rublev eased through with a straight-sets win over Alejandro Davidovich Fokina.

Data Debrief

With his triumph over Seyboth Wild at the Madrid Open, Alcaraz has now won 93.3 per cent of his games at the tournament. That is the highest win percentage of any player with at least 10 games played in a single ATP-1000 event since the format was introduced in 1990.

Against Seyboth Wild, Alcaraz won 27 of his 31 first-serve points, also recording 19 winners to his opponent's 10 as he dominated the contest on his way to victory.

Carlos Alcaraz continued his fine record at the Madrid Open with an emphatic 6-2 6-1 victory over Alexander Shevchenko on Friday.

The two-time defending champion made it 12 straight wins at his home tournament to ensure he will face Brazilian Thiago Seyboth Wild in the last 32.

Alcaraz was playing his first match on the ATP Tour since March 28 after being unable to compete in the Monte-Carlo Masters and Barcelona Open due to an arm injury.

But he was still able to make a fine start to his clay-court season, breaking serve in the first game and racing to victory in only one hour and eight minutes.

Data Debrief

Sometimes the scoreline can be harsh on a beaten player, but on this occasion Alcaraz was clearly dominant, breaking the Kazakh seven times in the match and forcing 11 break-point opportunities while conceding only three for his opponent.

That allowed the Spaniard to claim a dominant victory despite being broken once in each set. He will now turn his attention to a clash with Seyboth Wild, who battled past Lorenzo Musetti with a 6-4 6-4 win.

Carlos Alcaraz considers "dangerous" Jannik Sinner as the world's best player and the man to beat at the Madrid Open.

Sinner has won three titles in 2024, including his maiden grand slam crown at the Australian Open, and is the top seed in the Spanish capital.

Novak Djokovic is absent from the Masters 1000 tournament but will remain the top men's player regardless of how far Sinner advances.

And while the Italian's only appearance on clay this year saw him lose to Stefanos Tsitsipas in the semi-finals of the Monte-Carlo Masters, Alcaraz knows full well what he is up against should the pair cross paths.

"He's dangerous. He's the best player in the world right now," Alcaraz said in his pre-tournament news conference.

"I think [some people] think his tennis doesn't suit well to the clay, but he has had results on clay as well.

"He can win every tournament he goes to, and obviously I'm fighting with him and with Novak to be world number one. I'm trying to stay there, but honestly it is going to be difficult."

World number three Alcaraz was unable to compete in Monte-Carlo, as well as the Barcelona Open, due to an arm injury.

However, the Spaniard is relishing the chance of returning to clay-court action on home soil when his pursuit of a 14th Tour-level title begins against either Arthur Rinderknech or Alexander Shevchenko on Saturday.

"For me, it's really important to be at 100 per cent here in this tournament," he said. "Playing here is so special.

"It's the tournament where a lot of family can come to watch my matches, a lot of friends as well, and for me it's really special to play in front of my home crowd as well.

"I would love to play at 100 per cent just to give them the opportunity to enjoy my tennis and give myself the chance to get a good result here."

Alcaraz is aiming to become the first player to win three successive Madrid Open crowns and is on a collision course to meet Sinner in the final.

The 20-year-old ended Sinner's winning streak with victory in their BNP Paribas Open final showdown last month, with that a rare blemish for the latter.

While Sinner has been the best male player this year, boasting a record of 25 wins to two losses, he believes there is still room for improvement.

"I don't want to put pressure on myself," he told reporters ahead of the tournament. "I'm living a very positive moment, winning a lot of matches.

"I just try to keep going like this. In my mind, I know that I can and have to improve if I want to win more.

"I am searching for new opportunities and I feel like that every tournament I play, there can be a good opportunity trying to show that my level has raised. 

"Showing what I have improved and that's for sure something that I would like to do here. This is a new opportunity, new tournament and we'll see how it goes."

Gregor Dimitrov beat top seed Carlos Alcaraz in straight sets to book a place in the Miami Open semi-final.

The Bulgarian, seeded 11th, won 6-2 6-4 to book a last-four meeting with Germany’s world number five Alexander Zverev.

Dimitrov made a fast start as he opened a 3-0 lead and Alcaraz, chasing back-to-back titles after winning in Indian Wells, was never able to get back on terms.

He fought back from 4-1 down in the second set, but Dimitrov broke again to seal his second successive win over the Spaniard.

“I think overall, to win against him, you have to play at your best; that’s just how it is,” said Dimitrov. “I came into the match very focused and extremely clear what I had to do.

“Sometimes simplicity is genius. It’s very, very hard to do it, especially when you play against an opponent like that, but I was really able to dictate the game, read the game a little bit better than last time.

“Overall, I think a very great match on my end and I’m just happy I finished in straight sets.”

Zverev ended unseeded Fabian Marozsan’s run with a 6-3 7-5 success.

The Hungarian had beaten top 10 pair Holger Rune and Alex de Minaur to reach the last eight, but could only muster two break points as Zverev won 80 per cent of points on his first serve.

“I’m happy to be back in these late stages of these tournaments, playing the best players in the world, I think there are only those left,” said Zverev, who reached the final in Miami in 2018.

Defending champion Daniil Medvedev will meet Jannik Sinner in the other semi-final in a rematch of the Australian Open final.

Carlos Alcaraz defeated Russia’s Daniil Medvedev 7-6 (5) 6-1 on Sunday to win his second-straight BNP Paribas Open title at Indian Wells.

The world number two took only one hour and 42 minutes to claim victory, marking Alcaraz’s first title since his triumph at Wimbledon last year.

The 20-year-old Spaniard began the Indian Wells tournament with a 6-3 record on the season and an injured ankle, which he sustained during his latest outing in Rio de Janeiro.

Medvedev started strong in the match’s opening rounds, establishing a 3-0 lead as Alcaraz’s errors began to pile up.

It did not take long for Alcaraz to find his feet though, breaking back before matching the world number four to force a tie-break.

He almost let an early lead in the tie-break slip by, but recovered again to take the first set in just over an hour.

Once he had broken out in front, the world number two was barely troubled in the second set en route to retaining his Indian Wells title.

He told reporters on-court after the match that the win had bolstered his confidence following his Rio injury scare.

“Winning this tournament means a lot to me because the week before it began, I had a lot of doubts about my ankle,” Alcaraz said.

“I remember my first practice here was just 30 minutes with no movement, and probably the first practice with really good tennis players was really tough for me because I thought I was not going to play my best.”

He added: “I was not feeling well with my ankle, so a lot of doubts for me. But once I stepped on the court, the first round, I started to feel better.”

Carlos Alcaraz ended Jannik Sinner’s winning run as he claimed a place in the BNP Paribas Open final 1-6 6-3 6-2.

Australian Open champion Sinner had won 16 straight matches to begin the year – and 19 in all stretching back to last season – but the number three seed had no answer to the Spaniard after winning the first set.

Defending Indian Wells champion Alcaraz was broken twice after a three-hour rain delay as Sinner raced to a 6-1 first set victory.

But having faced deuce on his opening service game of the second set, the Spaniard grabbed the initiative with an early break.

He saved break points in successive games and served out to level the match.

Alcaraz, who would have surrendered the world number two spot to Sinner with a defeat, again broke early in the deciding set.

He dropped just three points on his serve, rattling off five straight games to lead 5-1, clinching victory on his third match point in just over two hours.

“I stayed strong mentally,” said Alcaraz. “I think that’s a really important part in this game. You have to be strong mentally if you want to overcome these kind of matches, a set down against someone that’s playing an unbelievable game.

“I changed my style a little bit, I changed my game a little bit and I think it worked very well. I’m really happy to beat Jannik and be in the final again.”

World number two Carlos Alcaraz raced into the quarter-finals of the BNP Paribas Open with a straight-sets win over Fabian Marozsan in Indian Wells.

The Spaniard, bidding to become the first player to defend the title since Novak Djokovic in 2016, won 6-3 6-3 in an hour and a quarter.

Hungarian Marozsan, 24, came into the match with a rare winning head-to-head record against Alcaraz, having beaten him on the Rome clay last year in their only previous meeting, one of the shock results of the season.

The Wimbledon champion quickly went about taking his revenge, winning four games in a row from 3-2 down to take the first set.

A solitary break for 4-2 in the second proved enough to wrap up the match and book a last-eight meeting with Alexander Zverev.

“Honestly I was nervous before the match, playing against someone who beat you, let’s say easily, it was difficult for me to approach the game,” Alcaraz said in his on-court interview.

“But I’m happy with the win. Today I knew better what I needed to do than in Rome.”

Zverev took down Australian Alex de Minaur after he lost the first set before coming back to win 5-7 6-2 6-3.

Australian Open champion Jannik Sinner continued his stellar start to the year, recording his 18th straight win in a victory over American Ben Shelton 7-6 (4) 6-1.

Stefanos Tsitsipas, the 11th seed from Greece, was on the end of an upset as he slipped to a 6-2 6-4 defeat to Czech youngster Jiri Lehecka.

Carlos Alcaraz must ignore the comparisons to fellow Spanish tennis great Rafael Nadal otherwise it will "hinder his career".

That was the message from former Dutch player Richard Krajicek, who won the Wimbledon men's singles title back in 1996.

Alcaraz triumphed at Wimbledon last year as well, his second major title after winning the US Open in 2022.

Though veteran Nadal has some 22 grand slam titles to his name, two behind the ever-reliant and ruthless Novak Djokovic, comparisons continue to be drawn between the two Spaniards.

"If he starts to think about it or live up to it or try to beat it, then it will hinder his career," Krajicek said of the similarities between Nadal and Alcaraz.

"His name is Carlos Alcaraz, he said it himself and he's not the new Nadal. Nadal is a legend and he's going to do what he has to do.

"I think by winning two grand slams, being number one, I don't think he feels any pressure or like, 'I have to do this or this'. He's improved already so much.

"I don't think he has too much to prove and he's just playing for the love of the game and he's going to win many more Grand Slams and he will be number one for many weeks also."

An athletic, bustling right-hander Alcaraz has the pure power, mixed with delicate control, to trouble major-title contenders for the next decade or so.

However, Krajicek says it is Alcaraz's passion for the sport that is most impressive.

"I like everything about this game. I mean, he's physically good, he's fast, I love his mentality on the court. Also like Rafa, very humble person, and he can do it all," he added.

"He can play, he plays from the base, and he's got a big forehand, he's got a very good touch on the drop shot. He can volley. Yeah, and he really loves the game.

"When he played the US Open and it was a really important point, and they were playing for number one in the world. It was one set all, Alcaraz loses the point, but the point was unbelievable, and Alcaraz smiled to his box 'Wow, I just played a great point and I love this game'.

"So for me, then I became a fan. I'm like, 'Wow, you really love this game'. So that's so great to see."

Richard Krajicek believes it will hurt Carlos Alcaraz's career if he compares himself too much to Rafael Nadal.

Alcaraz is being hailed as Spanish tennis' next big hope with Nadal nearing the end of a hugely decorated career, one that has seen him win 22 grand slam titles, two behind Novak Djokovic at the top of the all-time list.

Alcaraz himself has claimed two grand slams at the age of 20, winning the US Open in 2022 before following it up by claiming Wimbledon glory the following year.

Despite the comparisons, Krajicek hopes Alcaraz doesn't think too much about comparing himself with his countryman Nadal.

"If he starts to think about it or live up to it or try to beat it, then it will hinder his career, I think, a little bit," said Krajicek, speaking to Stats Perform at the Rotterdam Open. "But no, his name is Carlos Alcaraz. He said it himself. And he's not a new Nadal.

"Nadal is a legend. And he's going to do what he has to do. And I think by winning two grand slams, being number one, I don't think he [Alcaraz] feels any pressure or like, I have to do this or this.

"He's proved so much already. I don't think he has too much to prove. And he's just playing for the love of the game. He's going to win many more grand slams and be number one for many weeks also."

Krajicek thinks Alcaraz's all-round game has the potential to take him to the top, if he hasn't reached it already.

"I like everything about his game," Krajicek added. "I mean he's physically good, he's fast, I love his mentality on the court."

"Also like Rafa, [he is] a very humble person and he can do it all. He can play serve and volley, he plays from the base, he's got a big forehand, he's got a very good touch on the drop shot, he can volley."

Krajicek pointed to Alcaraz's affection for the sport of tennis as a particularly infectious part of his game.

"He really loves the game," Krajicek continued. 

"I think when he played the US Open, there was a huge point in the final and it was a really important point. And they were playing for number one in the world.

"It was one set all, and Alcaraz loses the point, but the point was unbelievable. And Alcaraz smiles to his box like, 'Wow, I just played a great point, and I love this game'.

"So for me, then I became a fan. I'm like, 'Wow, you really love this game'. That's so great to see."

It is only a "matter of time" until Carlos Alcaraz is the number one tennis player in the world, according to Richard Krajicek.

At the age of 20, Alcaraz has already won Wimbledon and the US Open, becoming world number one in September 2022.

He was defeated in the quarter-finals of the Australian Open to kick off this year's grand slams, though, failing to win any of the three tournaments in which he has played in 2024.

However, former world number four Krajicek believes Alcaraz is on his way to becoming the best, despite dropping to number two in the world rankings.

"His potential is very high," Krajicek told Stats Perform. "I think he's the future number one.

"I'm not saying anything special because he's beaten everybody. He beat Djokovic three times out of the last four times they played. He beat Medvedev from being two sets to love down, which shows how mentally and physically strong he is.

"So for me, it's a matter of time until he becomes number one. I think he can play on all surfaces, maybe clay is his worst surface but all the other surfaces you would say he's a title contender."

With the 'Big Three' of Roger Federer, Rafael Nadal and Novak Djokovic already retired or nearing the end of their storied careers, there's been much discussion over who will fill their boots.

Alcaraz has already proved his abilities, while 22-year-old Italian Jannik Sinner claimed Australian Open glory to kick off this year having reached the semi-finals of Wimbledon in 2023.

Krajicek feels those two will lead the way for the next era of men's tennis, saying: "It's difficult to say who the next generation will be, but I think Alcaraz and Sinner will have a good rivalry. They already have played unbelievable matches.

"Of course, Alcaraz has already been number one, won two Grand Slams. Sinner is now slowly coming also to that level. He is number four, maybe number three after this week."

However, Krajicek has reservations over whether the likes of Alcaraz and Sinner can reach the legendary status of the 'Big Three'.

"To really have the same kind of rivalry, I don't know if that's possible," Krajicek added. "I mean, together, Federer, Nadal and Djokovic won 66 Grand Slams. That's incredible. In every Grand Slam, they were in the final or winning. It's just amazing.

"I don't know if it's possible to have two players or three players that basically win every Grand Slam they play. But I believe those two are going to be the two biggest names for the next couple years."
