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Carlos Alcaraz has withdrawn from next week's Italian Open due to the arm injury that troubled him at the Madrid Open, where Andrey Rublev and Felix Auger Aliassime will face off in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– who had won his previous 24 matches at Spanish clay-court events – looked tired throughout that match and has now withdrawn from next week's ATP 1000 Masters event in Rome.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.

Jiri Lehecka progressed to the first ATP Masters 1000 semi-final of his career as Daniil Medvedev retired hurt on Thursday at the Madrid Open.

Lehecka, who beat the great Rafael Nadal in the last 16, had just taken the first set 6-4 when Medvedev threw in the towel.

Medvedev had earlier received treatment from the physio, having seemingly struggled when moving to his right side.

"It's never easy in a match like this," Lehecka said. "If I were to choose the way how to win this match, it wouldn't be like that.

"So of course, it's never easy to see your opponent struggling, but at that moment, you just need to focus on yourself, trying to get the maximum level out of yourself."

Lehecka will face Felix Auger-Aliassime, who progressed thanks to a walkover following Jannik Sinner's withdrawal, for a place in the final.

Data Debrief: Czech mates

Lehecka is the third Czech player to reach the semi-finals in Madrid, following Jiri Vovak and Tomas Berdych.

Should Lehecka reach the final, he will move into the top 20 of the ATP rankings for the first time.

Jannik Sinner has withdrawn from the Madrid Open due to a hip injury ahead of his scheduled quarter-final clash with Felix Auger Aliassime.

The world number two was due to face Auger Aliassime for a place in the semi-finals after fighting back to overcome Karen Khachanov in three sets on Tuesday.

However, the Italian has been advised to withdraw to avoid aggravating an issue with his right hip, which he says has troubled him throughout the tournament. 

Sinner, who is 28-2 for the season and won his first grand slam title at the Australian Open earlier this year, wrote on X: "Very sad to have to withdraw from my next match here in Madrid. 

"My hip has been bothering me this week and has slowly been getting more painful. Taking the advice from the doctors, we decided it's best to not play further and make it worse."

Sinner's withdrawal means Auger Aliassime will advance to his first ATP Masters 1000 semi-final since 2022, with Daniil Medvedev or Jiri Lehecka – who eliminated Rafael Nadal on Tuesday – up next for the Canadian. 

On the other side of the draw, two-time defending champion Carlos Alcaraz suffered a surprise exit at the hands of Andrey Rublev on Wednesday, with the Russian set to face either Taylor Fritz or Francisco Cerundolo in the last four.

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.

Rafael Nadal paid tribute to supporters after his farewell appearance at the Madrid Open ended following defeat to Jiri Lehecka in the last 16.

The 22-time grand slam champion bowed out after going down in straight sets against his Czech opponent, who prevailed 7-5 6-4 to set up a quarter-final clash with Daniil Medvedev.

Nadal was honoured following the conclusion of the final match at his home ATP Masters event, where he triumphed in 2008, 2010, 2013, 2014 and 2017.

Five banners to represent each of his titles were unfurled, displaying the message 'Gracias Rafa', while he was also presented with a trophy by tournament CEO Gerard Tsobanian and director Feliciano Lopez. 

"It's been a very special week for me, very positive in many ways, both personally and for my tennis," he said during his on-court interview.

"I had the chance to play again on court. A few weeks ago, two days before Barcelona, I didn’t know if I would compete in an official match again, and I've now played two weeks. It's been unforgettable.

"This is one of those days that when it arrives, it's very tough, but life and my body have been sending me signals for a long time.

"The only thing I can say is thank you. It's been an incredible journey that started when I was little. I came to Madrid for the first time in 2003, when the tournament was played indoors.

"The first time I came here feeling competitive was in 2005. It was one of the most exciting wins of my career. Ever since, the support has been unconditional from everyone. I cannot thank you enough.

"Even though it's not over, this is the last time I'll be in Madrid. You have given me a gift for the last 21 years that's more significant than any Grand Slam I have won. The emotions of playing in Madrid, in front of the Spanish fans, is something that will stay with me forever."

Iga Swiatek admits that, like Pedro Cachin, she would also swap shirts with Rafael Nadal following his Madrid Open exit.

The 22-time grand slam champion's farewell appearance at the clay-court ATP Masters tournament, which he has won five times, was ended by a straight-sets defeat to Jiri Lehecka.

Nadal had beaten Cachin in the last 32, with the Argentine subsequently asking his idol for his shirt as a memento following their clash.

Although Swiatek has never been tempted to follow suit with an opponent, the world number one acknowledged she might make an exception for the Spaniard.

"If I would play against Rafa, for sure I would ask for a T-shirt," she laughed.

"For sure, he was a huge inspiration. When I was younger, he was basically the only player I looked up to, but not because of his game on clay - more because of the way he is off the court and how he never gives up, and also his mentality."

Swiatek is through to the semi-finals in the ladies' draw after recovering from losing the opening set to defeat Beatriz Haddad Maia 4-6 6-0 6-2.

The Pole, who will play former US Open runner-up Madison Keys in the last four, equalled Serena Williams and Maria Sharapova as the fastest player to reach 25 WTA 1000 wins on clay, doing so in just 29 matches.

Jiri Lehecka claimed a memorable win over one of tennis' greats as he downed Rafael Nadal at the Madrid Open.

Nadal's farewell appearance at the tournament he has won five times came to an end with a 7-5 6-4 defeat on Tuesday.

The 22-time grand slam champion had been hoping to tee up a quarter-final against Daniil Medvedev.

Ultimately, though, world number 31 Lehecka was the man who progressed.

Lehecka ruined the hopes of the Nadal fans packed into the stands in the Spanish capital, and took control when he reeled off 10 straight points to take the opening set.

Nadal won the Madrid Open in 2008, 2010, 2013, 2014 and 2017, and said farewell to the crowd in an on-court interview following his defeat.

Data Debrief: Nadal falls short of milestone

Nadal had been hoping to win his 60th match at the Madrid Open, while he would have reached his 100th ATP Masters 1000 quarter-final had he won. This was his first defeat to a player ranked lower than 20th in the world since he went down to Pablo Cuevas in 2016.

Lehecka, meanwhile, will make his second appearance in the last eight of a Masters 1000 event.

Casper Ruud's hopes of building on his victory at the Barcelona Open were ended as he lost to Felix Auger-Aliassime at the Madrid Open.

Auger-Aliassime will now face top seed Jannik Sinner in the quarter-finals, after claiming a 6-4 7-5 victory over the fifth seed Ruud on Tuesday.

Ruud, runner-up at last year's French Open and a force to be reckoned with on clay, won in Barcelona earlier in April, but came unstuck against the Canadian.

It was not the only shock exit, as Alexander Zverev, the world number five, succumbed in straight sets to Francisco Cerundolo.

Earlier, Daniil Medvedev claimed his place in the quarters, in which he could face Rafael Nadal, by beating Alexander Bublik 7-6 (7-3) 6-4.

Data Debrief: Medvedev's milestone

Five of the six quarter-finals Medvedev has reached on clay have come at either ATP Masters 1000 or grand slam level.

He has now reached at least the quarter-final stage at all nine Masters events, too.

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.

Jannik Sinner has booked his place in the Madrid Open quarter-final, going the distance to beat Karen Khachanov 5-7 6-3 6-3 on Tuesday.

The top seed dropped a set for the first time at the tournament as an in-form Khachanov, but he shook off the concerns of a lingering hip injury to make a comeback.

After winning the second set, he then saved both break points he faced in the decider, finishing off a contest that lasted over two hours.

Sinner has reached the quarter-final of the Madrid Open for the first time and will face either Casper Ruud or Felix Auger-Aliassime next. 

Data debrief: Sinner overcomes first big test

Not only has the 22-year-old become the only player to reach the quarter-final at all four Master 1000 events in 2024, but he is the first to achieve that feat since Milos Raonic in 2016.

Sinner has also become the first Italian player to make the quarter-finals of all three existing ATP Masters 1000 events on clay, since 2009 when the Madrid Open took the place of the Hamburg Masters.

Rafael Nadal battled to victory over three hours on the court against Pedro Cachin at the Madrid Open on Monday to seal a 6-1 6-7 (5-7) 6-3 win to reach the last 16.

The former world number one looked back to his best as he cruised through the opening set but was pushed hard in the second by Cachin.

Nadal came from behind to level at 5-5, but Cachin eventually sealed the set on his third set point.

The Spaniard then rallied in the third set, cutting down on his errors to regain control and advance to the fourth round at a tour-level event for the first time since 2022.

Nadal is one step away from booking his place in a 10th consecutive quarter-final in Madrid and will face Jiri Lehecka on Tuesday in the next round after the 30th seed overcame Brazilian qualifier Thiago Monteiro in two sets.

Daniil Medvedev overcame a stern test against Sebastian Korda at the Madrid Open on Monday, fighting back from the brink of defeat to seal a 5-7 7-6 (7-4) 6-3 win and reach the last 16.

The world number four was staring at an early elimination when Korda took the opening set and put himself within two points of victory on two occasions, at both 5-4 and 6-5 up in the second.

However, Medvedev twice held firm on his own serve to force a tie-break, and the pair exchanged mini breaks before the 2021 US Open champion seized control to take it 7-4.

Medvedev's performance was error-strewn in parts, but he found more consistency in the third set, claiming the all-important break eight games in after repeatedly testing Korda's forehand. 

Medvedev will now face Alexander Bublik for a place in the quarter-finals on Tuesday after the 17th seed overcame Ben Shelton in three sets.

Data Debrief: Medvedev overcomes awkward opponent 

Medvedev has not always had things all his own way against Korda, who eliminated him from the Australian Open and the Shanghai Masters in 2023.

Prior to Monday's match, he was 23-2 versus American players since the start of 2021, with both losses coming against Korda. However, having also beaten Korda en route to the Indian Wells Open final last month, he seems to have put that hoodoo behind him.

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.
