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.

Elena Rybakina saved two match points as she outlasted Yulia Putintseva to win a dramatic encounter 4-6 7-6 (7-4) 7-5 in the Madrid Open quarter-finals on Wednesday.

The world number four was on the brink of defeat at 5-2 down in the third set, with her fellow Kazakhstani Putintseva eyeing a third win in as many head-to-head meetings between the pair.

However, Rybakina came up with one of the shots of the tournament on Putintseva's first match point, capitalising on a drop shot clipping the net cord to produce a nonchalant winner.

The 2022 Wimbledon champion didn't look back from that moment on, producing back-to-back breaks before holding her nerve through a tense final service game, converting her fourth match point to wrap up a gruelling two-hour, 48-minute contest.

Rybakina has now won 16 successive matches on clay, and she will face either Aryna Sabalenka or Mirra Andreeva in the semi-finals on Thursday.

Data Debrief: Rybakina rampant 

Rybakina is the form player on the WTA circuit, with Wednesday's win her 30th of 2024, more than any other player.

She is just the second player to win 30 or more matches in tournaments starting within the first four months of a calendar year, after Iga Swiatek managed 32 victories during the same span in 2022. Swiatek, of course, went on to win the French Open and US Open titles that season.  

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.

Iga Swiatek has booked her place in the Madrid Open semi-finals after battling back from a set down to defeat Beatriz Haddad Maia.

The top seed, who made it to the final last year, dropped a set for the first time in this tournament before recovering to win 4-6 6-0 6-2 in a match that lasted just short of two-and-a-half hours.

These two players met in the French Open semi-finals last year and 11th seed Haddad Maia was eyeing an upset when she fought back from 4-1 down to claim the opener.

But Swiatek dropped serve just once in the next two sets as she assumed full control and swept to victory, powered by winning eight straight games from the start of the second set.

Data Debrief: Swiatek statistics up there with the best

Up next for Swiatek will be a last-four clash against either Ons Jabeur or Madison Keys, who play later on Tuesday. That will be her 15th WTA 1000 semi-final appearance since 2020, with no other player having made it to double figures (Aryna Sabalenka and Maria Sakkari are the next best on eight each).

Beating Haddad Maia also means Swiatek has equalled Serena Williams and Maria Sharapova as the fastest player to reach 25 WTA 1000 wins on clay, doing so in just 29 matches.

And Swiatek's emphatic second set saw her tie Coco Gauff for the most number of 6-0 sets won so far this year. They both have seven, just ahead of Sabalenka (five).

Defending champion Sabalenka plays Mirra Andreeva in the last eight on Wednesday after battling past Danielle Collins in three sets. All three of her wins so far have been in deciding sets.

The other last-eight clash is between Elena Rybakina and Yulia Putintseva.

Madison Keys is through to the quarter-final of the Madrid Open for the first time in her career after rallying to a 7-6 (7-4), 4-6, 6-4 win over Coco Gauff on Monday.

The 29-year-old trailed 5-2 in the first set and 4-2 in the third set but rallied in both to come from behind to beat the number three seed.

Despite winning the second set, Gauff struggled to find her rhythm, suffering from 13 double faults, including two in the final game.

Keys will face former Madrid Open champion Ons Jabeur for a spot in the semi-final after the number eight seed overcame Jelena Ostapenko in straight sets.

Data debrief: Keys reaches new milestone

Having lost in the first round in seven of her nine previous trips to the Spanish capital, Keys has now bettered her previous best finish in Madrid - a third-round showing in 2016.

Keys hadn't won three matches in a row since reaching the US Open semifinals last year.

Madison Keys is through to the quarter-final of the Madrid Open for the first time in her career after rallying to a 7-6 (7-4), 4-6, 6-4 win over Coco Gauff on Monday.

The 29-year-old trailed 5-2 in the first set and 4-2 in the third set but rallied in both to come from behind to beat the number three seed.

Despite winning the second set, Gauff struggled to find her rhythm, suffering from 13 double faults, including two in the final game.

Keys will face former Madrid Open champion Ons Jabeur for a spot in the semi-final after the number eight seed overcame Jelena Ostapenko in straight sets.

Data debrief: Keys reaches new milestone

Having lost in the first round in seven of her nine previous trips to the Spanish capital, Keys has now bettered her previous best finish in Madrid - a third-round showing in 2016.

Keys hadn't won three matches in a row since reaching the US Open semifinals last year.

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.

Iga Swiatek continued her march towards back-to-back Madrid Open finals by crushing home favourite Sara Sorribes Tormo in straight sets in the last 16 on Monday.

The world number one – who lost to Aryna Sabalenka in last year's final – made a poor start as Sorribes Tormo surprisingly broke her serve in the opening game, but that only spurred her into action as she dominated from there.

Swiatek broke back immediately and reeled off 12 straight games to advance 6-1 6-0, going one better than her 6-1 6-1 win over Sorana Cirstea in the last 32.

On clay, Swiatek has now won nine of her 55 WTA 1000-level sets by 6-0, with that remarkable rate of 16.4 per cent being the highest of any player to have played 10 or more sets in the format's history (completed matches only).

Swiatek will face Beatriz Haddad Maia in the last eight on Tuesday, with the Brazilian upsetting Maria Sakkari 6-4 6-4 to reach her first quarter-final at the event.

Data Debrief: Swiatek unstoppable on clay?

Swiatek's meeting with Haddad Maia will represent her 14th quarter-final in 18 WTA events played on clay, meaning she has reached that stage on 77.8 per cent of her appearances on the surface.

Since the turn of the century, only two players have a higher rate of quarter-finals reached on clay – Martina Hingis (85.7 per cent, 12/14) and Justine Henin (80.6 per cent, 25/31).

Ons Jabeur cruised into the Madrid Open quarter-finals on Monday, spending just over an hour on court in a statement 6-0 6-4 win over ninth seed Jelena Ostapenko. 

Jabeur, who won her first and so far only WTA 1000 title in Madrid in 2022 then missed last year's tournament through injury, made it nine wins in a row in the Spanish capital to book a last-eight meeting with either Coco Gauff or Madison Keys.

Eighth seed Jabeur only needed 68 minutes to see off the former French Open champion, not dropping a game in a 21-minute opener in which she won 88 per cent of first-serve points.

Ostapenko improved in the second set, breaking back immediately after losing serve in the opening game, but Jabeur got the crucial break to go 5-4 up before serving the contest out.

Data Debrief: Jabeur dominates on the clay

Jabeur's win sealed her third quarter-final appearance at a WTA 1000-level event on clay since 2020. Only world number one Iga Swiatek (four) has reached more during that span.

A dominant start did the trick for the Tunisian on Monday, as she became the first player to take an opening set 6-0 against a top-10 ranked player in Madrid since the 2021 final, when Aryna Sabalenka did so in her victory over Ashleigh Barty.
