Alexander Zverev ended a three-year wait for an ATP Masters 1000 title as he rallied to beat Matteo Berrettini in the Madrid Open final on Sunday.

The German had to do it the hard way at La Caja Magica over the past week, having previously seen off five-time winner Rafael Nadal and Dominic Thiem en route to the showpiece.

He was in a spot of bother against his Italian opponent at the end of a gripping first set that Berrettini took in a tie-break, Zverev's efforts in coming back from 5-0 down and earning a set point ultimately for nothing.

Berrettini eventually sealed the lead with his fourth set point but Zverev played with renewed focus at the start of the second, taking full advantage of a succession of mistakes with the score at 4-4 to force a decider.

Zverev's greater endurance in rallies then paid dividends early in the third as he broke to go 3-2 up, and Berrettini only won one more game as the German triumphed 6-7 (10-8) 6-4 6-3 to win the tournament for a second time.

Speaking afterwards, he said: "It is great [to win this title], especially after losing my last three finals I played at Masters 1000 events. This is definitely special and I just want to enjoy this one.

"[Berrettini's] game style showed it all. I didn't play anybody this week that can serve 235[km/h] on clay and serve 230km/h kick serves.

"It definitely was a different match and I am extremely happy right now."

On competing at the Internazionali d'Italia next, he added: "Rome is also an event I like and enjoy, so I hope I can perform [in] the same way as I did here and we will see how it goes there. I feel awesome."

This was the first time Zverev has beaten three or more top-10 players in a single competition since his ATP Finals victory in 2018.

Matteo Berrettini will take on Alexander Zverev in the Madrid Open final on Sunday after overcoming Casper Ruud 6-4 6-4 in the last four. 

Eighth seed Berrettini has enjoyed a superb debut tournament in the Spanish capital, the 25-year-old dropping just one set on his way to becoming the first Italian to make the Madrid Open final. 

Berrettini, who won the Serbia Open last month, is just the third Italian ATP Masters 1000 finalist since the series was established in 1990, after Fabio Fognini and Jannik Sinner. 

"It's a great, unbelievable feeling, especially coming from Monte Carlo where I wasn't feeling that good," Berrettini said in quotes reported by the ATP website. 

"I won in Belgrade and now I'm in the final, so I'm really looking forward to playing against Sascha [Zverev]. I hope I enjoy it tomorrow the way I enjoyed tonight.

"I saw him [Zverev], he's playing really good. He's solid. He moves well. For his height, he's really good. He serves well. I mean, he's in the final. He beat Rafa [Nadal] and Dominic [Thiem], probably the best players on clay.

"It's going to be a challenging match, but I'm in the finals. I guess the best two guys are going to play each other."

Berrettini returned supremely throughout Saturday's match, nullifying Ruud's usually potent serve, and believes his aggressive approach was key to victory.

"My serve is my weapon, but today I think I returned a lot and I put pressure on him," Berrettini said. "I was just playing more aggressive. He's kind of like me, he likes to run around the forehand and play with spin. But I guess today I was playing better than him.

"The other time he beat me, so it's always a great fight against him. He reached three semi-finals in a row so he was feeling confident. I guess that's why I'm maybe even more happy with my win today."

In the earlier semi-final, Zverev followed up his famous win over home favourite and 20-time grand slam champion Rafael Nadal in the previous round by defeating Dominic Thiem.

Austrian Thiem had won the last four meetings between the two, including in last year's Australian Open semi-final and the US Open decider, where he came from two sets down to win in an incredible fifth-set tie-break.

However, Zverev was not to be denied this time, a 6-3 6-4 result keeping him on course for a repeat of his 2018 triumph at the event in the Spanish capital.

Aryna Sabalenka won the Madrid Open after a 6-0 3-6 6-4 victory over world number one Ashleigh Barty on Saturday.

Sabalenka wrapped up the first set to love in just 25 minutes as an unusually sluggish Barty struggled to find any kind of rhythm to her game.

Barty, who had won 16 consecutive matches on red clay, rallied in the second set to get herself back on level terms.

At 4-4 in the deciding set Sabalenka broke Barty and then held her nerve on serve to secure her 10th WTA Tour career title which will see her climb up to fourth from seventh in the world rankings on Monday.

Barty was on a streak of nine consecutive WTA Tour titles and had not lost to an opponent in the top 10 since the WTA Finals in 2019.

But in-form Sabalenka had not dropped a single set in Madrid in the lead-up to the final and began in imperious fashion.

The 23-year-old from Belarus produced a clinical first set, dropping just four points, as Barty failed to win a single game in the set to record a bagel for the first time in four years.

The pair exchanged breaks in the second set before Australian Barty, 25, finally discovered some momentum to break her opponent again to seal the set.

Sabalenka squandered a one-set lead to lose to Barty in the Stuttgart Open final two weeks ago.

And Barty, also playing in the final of the tournament for the first time, had threatened to break her opponent at 4-3 in the decider.

But this time Sabalenka took her chance when Barty fluffed a drop shot and then double faulted to give her three break points, converting at the first time of asking with a powerful backhand.

Sabalenka then clinically sealed victory with a flawless service game to love, clinching victory when Barty smashed a forehand into the net.

"To be honest, after the final in Stuttgart I was injured, I couldn't move and wanted to withdraw," Sabalenka said in an on-court interview after the win.

"But the recovery was good, in four days I feel better and now I'm the champion. It's been an amazing week."

Alexander Zverev can see his rivalry with Dominic Thiem continuing for many years after he came out on top in their latest duel at the Madrid Open.

The German followed up his famous win over home favourite Rafael Nadal by defeating Austria's Thiem 6-3 6-4 in the semi-final on Saturday.

Zverev, who won this event in 2018, will meet either Casper Ruud or Matteo Berrettini in the final.

Thiem had won the last four meetings between the two, including in last year's Australian Open semi-final and the US Open final, where he came from two sets down to win in an incredible fifth-set tie-break.

Zverev said after his victory over Nadal that he would be thinking about that crushing loss in New York prior to his meeting with Thiem.

And he was able to gain a small measure of revenge for those recent grand slam defeats in the Spanish capital.

"We have had some fantastic matches," said Zverev. "We have played the biggest matches in the world. We have played Masters 1000 finals, we have played grand slam finals and [the rivalry] is still developing.

"It is still going to go on for a few more years. Hopefully we will play a few more amazing matches. It feels very [sweet to win], it is a rivalry where he kicks my a** most of the time!

"It is going to mean a lot to me [if I can win the final].

"I am definitely looking forward to playing another big final and I hope I can turn it my way this time."

A solitary break of serve was enough for Zverev to claim the opening set.

He recorded two breaks in the second to go 4-1 up and although Thiem got one strike back, two more holds gave Zverev - who forced 11 break points to his opponent's two - a big victory.

The world number six is yet to drop a set this week but has lost his last three Masters 1000 finals going into his latest attempt on Sunday.

Thiem, meanwhile, has reached the Madrid Open semi-finals in four straight years but it still waiting for his first triumph at the tournament.

Rafael Nadal said his shock quarter-final defeat to Alexander Zverev at the Madrid Open was "very difficult to understand". 

Nadal, a five-time champion at the event, was a break up in the first set of his 15th quarter-final at Caja Magica but lost 6-4 6-4 in an hour and 44 minutes.

The win was the biggest of Zverev's career on clay and confirmed his rise to second in the ATP Rankings. 

While Nadal said he was largely pleased with his displays in the Spanish capital, he was at a loss to explain the manner of his defeat on Friday. 

"I'm leaving Madrid with an overall positive feeling, but at the same time with the ugly feeling of having played a match like this today against a great player," Nadal told a media conference. 

"I think for most of the first set, I was playing better than him. And this is the negative part; while playing better than him in the first set, I still lost 6-4.

"This is very difficult to understand, especially for me. When this happens to me, it's usually in the opposite way. I find a way to win sets even though I'm not playing my best or as good as the opponent.

"I felt like I was playing better for much of the first set, but after a couple of errors – unjustifiable errors at the worst times – I found myself down a set.

"The outlook of the match changed there, both for me and for him. I knew then that a lot of suffering was waiting for me [in the second set], and for him, the knowledge that he just took a huge step forward during the match."

Zverev will face Dominic Thiem in the last four after the Austrian overcame John Isner 3-6 6-3 6-4 in an hour and 55 minutes. 

Thiem, who has now made it to the past four Madrid Open semi-finals, said: "I think we all know that he is one of the best servers in history and the altitude here in Madrid makes it even tougher to return his serve.

"I was a little bit surprised by his return games. I think he actually attacked both of my serves, the first and the second, and it took me a while to get used to it."

Casper Ruud will meet Matteo Berrettini in the other semi-final. 

Norwegian Ruud eased past Alexander Bublik 7-5 6-1 to make it three consecutive clay ATP Masters 1000 semis, while Berrettini beat Cristian Garin 5-7 6-3 6-0. 

Alexander Zverev recorded the biggest win on clay of his career as he stunned Rafael Nadal in the quarter-finals of the Madrid Open.

Nadal, a five-time champion at this event, was a break up in the first set of his 15th quarter-final at Caja Magica but lost 6-4 6-4 in an hour and 44 minutes.

Zverev had won the previous two meetings with Nadal, both on indoor hard courts, after losing five consecutive matches against the 20-time major champion including a 6-1 6-1 rout in Monte Carlo in their first clay contest four years ago.

The world number six has five clay-court titles to his name, including this event in 2018, but defeating 13-time French Open champion Nadal on his favourite surface in front of a home crowd ranks among Zverev's finest achievements.

It looked as though Nadal was assuming control when he broke to love to lead 4-2 in the first set, but Zverev responded with a break back at the first time of asking.

The German had spoken of the Madrid courts playing faster than other clay events and the conditions certainly seemed to suit his fearless approach as Nadal struggled to deal with his crosscourt backhand.

He won the next three games to clinch a first set in which he lost just four of 16 points behind his first serve.

While Zverev looked increasingly confident, mixing up his shot depth and frequently coming to the net, Nadal cut an unusually frustrated figure even as he showed customary battling qualities to ward off a break point at 1-1.

However, more powerful hitting from Zverev saw him break to lead 4-2, and although he missed two chances for a double break, he closed out the match with minimal fuss.

"Definitely one of the biggest wins of my career," Zverev, who will face Dominic Thiem in the semi-finals, told Amazon Prime Sport. "Beating Rafa on clay is one of the toughest things to do in our sport."

Rafael Nadal saw off Alexei Popyrin to reach the Madrid Open quarter-finals on a day that saw Daniil Medvedev and Stefanos Tsitsipas suffer surprise defeats.

World number two Nadal, chasing a record-extending sixth title on home soil, advanced 6-3 6-3 in a time of one hour and two minutes on Thursday.

Popyrin, playing in his first last-16 match at a Masters 1000 event, broke Nadal in the sixth game of the opening set but the Spaniard otherwise looked comfortable.

Nadal converted four of his six break points to advance through to the last eight for a 15th time, where Alexander Zverev awaits.

"It was difficult," Nadal said in his on-court interview. "The court today was slippery, it was very fast, very dry conditions. The ball was flying a lot. The beginning was super tough. 

"He was hitting every ball and hitting the spots. I'm happy with the victory. It was an important victory, he came here playing well. Every match is tough."

Zverev, who won the competition in 2018, beat British number one Dan Evans 6-3 7-6 (7-3) to set up a meeting with Nadal

However, second and fourth seeds Medvedev and Tsitsipas saw their participation come to an end at the hands of Cristian Garin and Casper Ruud respectively.

Medvedev, who is still yet to reach the quarters in Madrid, lost the only break of serve in the third game of the opening set but recovered by taking the second set in a tie-break.

Garin dominated the deciding set, the world number 25 breaking Medvedev twice and, after a short delay to fix a broken net, advanced 6-4 6-7 (7-2) 6-1.

Tsitsipas, who held championship point against Nadal in the Barcelona Open final, failed to break Ruud on a single occasion as he fell 7-6 (7-4) 6-4.

Alexander Bublik is next up for Ruud after beating Aslan Karatsev 6-4 6-3, while Matteo Berrettini - 7-6 (7-4) 6-4 winner against Federico Delbonis - will meet Garin.

Also vying for a place in the semi-finals are John Isner and Dominic Thiem, who are set to face off after beating sixth seed Andrey Rublev and Alex de Minaur respectively.

Ashleigh Barty will face the only woman on the WTA Tour to have beaten her since February after the world number one set up a Madrid Open semi-final with Paula Badosa.

Barty took her winning streak on the red clay to 15, overcoming ninth seed Petra Kvitova 6-1 3-6 6-3 to reach the last four in Madrid for the first time.

Among active players, the Australian's red-clay run is bettered only by Serena Williams (32 matches in 2013-14) and Sara Errani (16 in 2012).

The 2019 French Open champion is 24-3 for the season and has now won her last 10 matches against top-20 opponents and five of the last six with Kvitova.

Kvitova's hopes of claiming a rare win over Barty were boosted when she sent the match to a decider, but Barty took her formidable record in three-setters this year to 11-1.

"It's just always staying in the fight," Barty said of her performance in deciders this season. "Always staying in the hunt and never letting it slide away.

"That certainly doesn't guarantee results, doesn't guarantee success. It guarantees you give yourself the best chance to do what you do and to figure it out and to find your way."

Finding her way on the WTA Tour is 23-year-old Badosa, who moved up to a career-high ranking of 62 after a run to the semi-finals in Charleston last month.

She defeated Barty in straight sets en route to the last four having beaten Belinda Bencic earlier in the tournament.

Badosa got the better of Bencic again on home soil on Wednesday, prevailing 6-4 7-5, the Swiss paying the price for a string of unforced errors at the end of each set.

"I expect a completely different match," Badosa said of the reunion with Barty.

"She's the number one in the world. Now she knows me. Number one in the world, they don't like to make mistakes two times in a row, so for sure I expect a tough match and completely different to Charleston."

Aryna Sabalenka is through to the semi-finals after Elise Mertens retired from their clash with a thigh injury. Sabalenka had held a commanding 6-1 4-0 lead.

She will face Anastasia Pavlyuchenkova, who is into her first WTA 1000 semi in over a decade after recording her fourth top-25 win of the week by defeating Karolina Muchova in straight sets.

At L'Open 35 de Saint-Malo, sixth seed Arantxa Rus and seventh seed Jasmine Paolini each lost in the round of 16 but fifth seed Viktorija Golubic fought back to defeat Greet Minnen in three sets.

Rafael Nadal cruised to victory over birthday boy Carlos Alcaraz to start his Madrid Open campaign in impressive fashion.

The world number two moved into the last 16 with a 6-1 6-2 victory on Wednesday.

After being knocked out of the Monte Carlo Masters by Andrey Rublev in the last eight, Nadal bounced back to win the Barcelona Open last month and continued his momentum in this round-of-32 clash.

As wildcard Alcaraz turned 18, the spectators sang happy birthday to him but he could not mark the occasion with a famous result against his idol, with Nadal broken just once on his way to a 78-minute victory.

Five-time tournament winner Nadal converted five of his seven break points in a ruthless showing, with Real Madrid greats Iker Casillas and Raul in the crowd to watch him.

Nadal will play Alexei Popyrin, a straight-sets winner against rising star Jannik Sinner, in the next round.

Elsewhere, second seed Daniil Medvedev came from behind to defeat home hope Alejandro Davidovich Fokina 4-6 6-4 6-2. It was his first win in seven ATP Tour matches on clay.

"I am happy with the win," said the Russian.

"The first set wasn't easy and I thought it was going to be where I had another 25 break points and I wouldn't win. 

"I finally played quite well and did well in the third set. Madrid is a little faster than other clay tournaments, so it is better for my game."

The win means Medvedev has an 18-3 record this season and faces Chile's Cristian Garin next.

Medvedev's compatriot Aslan Karatsev beat Diego Schwartzman 2-6 6-4 6-1, having also defeated the French Open semi-finalist at the Australian Open this year.

In-form Karatsev will face Alexander Bublik next after his fourth top-10 win of the year.

Fifth seed Alexander Zverev said he was "clinical" in dispatching Kei Nishikori 6-3 6-2 in just 74 minutes, while fourth seed Stefanos Tsitsipas will play Benoit Paire later on Wednesday.

Elise Mertens twice came back from the brink to beat Simona Halep and reach a Madrid Open quarter-final against former doubles partner Aryna Sabalenka.

Third seed Halep was the highest-ranked player in action on Wednesday but came unstuck against Mertens despite taking the opener and leading by a break in each of the subsequent sets.

Mertens emerged a 4-6 7-5 7-5 winner after two hours and 34 minutes, defeating Halep for the first time on clay and only the second time on any surface.

There were opportunities for both players throughout and Halep struck first, losing her break lead in the first but recovering on this occasion.

The Romanian, a two-time winner who has also twice lost in the final in Madrid, twice cancelled out a deficit in the second but could not then capitalise on a lead of her own.

Mertens battled back and broke to love to level the match, then maintained her composure to see out a back-and-forth decider once Halep had again forged ahead.

"She played really well, and she definitely deserved to win because she was stronger in the end," Halep said.

"I cannot say I played bad, but I did some mistakes, important mistakes. Sometimes it's just a little bit and the match is going away."

Sabalenka is up next for Mertens, although she had a much more straightforward path through the third round.

Jessica Pegula held her up for only 52 minutes in a dominant 6-1 6-2 success.

In the same half of the draw, Anastasia Pavlyuchenkova upset another seed, following up her straight-sets victory over Karolina Pliskova by beating Jennifer Brady in three. She plays Karolina Muchova next.

At L'Open 35 de Saint-Melo, second seed Rebecca Peterson came from behind to see off Xiyu Wang, while Tamara Zidansek and Arantxa Rus also produced comebacks.

Nina Stojanovic survived three sets, but Christina McHale crashed out to Viktoriya Tomova.

Dominic Thiem surged to an emphatic victory on his return to the ATP Tour at the Madrid Open.

US Open champion and two-time Madrid Open runner-up Thiem was playing his first match in nearly two months on Tuesday, having taken a break to recharge.

But it did not take him long to get back into the groove, the third seed easing through his second-round match with American qualifier Marcos Giron 6-1 6-3 at the ATP 1000 event.

"I was uncertain how things will be going. The game worked out very well in the past days of practice, but I was always practising on the outside courts which are faster, which are smaller, so I was just not sure how it was going to be in the match," Thiem said.

"But there were some things which I think made [the match] a little bit easier after such a long time, especially the conditions in Madrid, which are great for me.

"Then [I have] amazing memories on this court, where I already played probably some of the best matches of my career. I think that's why things worked out quite well tonight."

Next for Thiem in the last 16 is Alex de Minaur, who was leading 6-2 3-0 when Lloyd Harris retired from their match.

It was a largely strong day for the seeded players in the Spanish capital, home hope and ninth seed Roberto Bautista Agut beating Marco Cecchinato 6-2 6-7 (3-7) 7-5 in a first-round clash.

Andrey Rublev – the sixth seed – came from a set down to beat Tommy Paul 6-7 (5-7) 6-3 6-4 and eighth-seeded Italian Matteo Berrettini joins him in the last 16 after defeating compatriot Fabio Fognini 6-3 6-4.

Jannik Sinner, who is seeded 14th, won in the first round after Guido Pella retired in the second set. However, four seeds did tumble out of the draw.

Felix Auger-Aliassime was thrashed 6-1 6-4 by Casper Ruud in the first round and his Canadian compatriot Denis Shapovalov was beaten 6-4 5-7 6-4 by Alexander Bublik in their second-round encounter.

Miami champion Hubert Hurkacz suffered a second successive second-round exit, the 12th seed defeated 5-7 7-6 (9-7) 6-3 by John Millman in a match that went the distance having lost at the same stage in Monte Carlo.

Carlos Alcaraz, a 17-year-old wildcard, will face Rafael Nadal in the second round of the Madrid Open, with the top seeds set to get their campaigns underway on Tuesday and Wednesday.

Alcaraz, featuring in an ATP Masters 1000 event for just the second time, was in impressive form as he saw off France's Adrian Mannarino 6-4 6-0.

The teenager, who will face Nadal on his 18th birthday on Wednesday, fired 19 winners as he took the initiative against his more experienced opponent and his reward is significant.

He became the tournament's youngest ever match winner, beating the record set by Nadal.

"For me, [to] play against Rafa is a dream come true," Alcaraz said as he readies himself to go up against the 20-time grand slam winner.

"Since I was a kid, I wished to play a match against Rafa and now I will be able to here [on] the Centre Court of La Caja Magica in Madrid. It is a really special match against Rafa."

He told Tennis Channel: "It's the best present for my birthday."

The biggest casualty of the day was 13th seed Grigor Dimitrov, who lost 3-6 6-3 7-6 (7-5) to Lloyd Harris early on, the South African now 4-0 against top-20 opponents this year.

Two qualifiers in Pablo Andujar and Marcos Giron played out a remarkable encounter that lasted three hours and 21 minutes.

The first set alone clocked in at just over an hour and a half, but eventually Giron came through the gruelling clash 6-7 (8-10) 7-6 (7-4) 7-5 to set up a meeting with third seed Dominic Thiem.

Fabio Fognini defeated Carlos Taberner 7-6 (7-4) 2-6 6-3 for the right to face eighth seed and Italian countryman Matteo Berrettini.

Diego Schwartzman, the seventh seed, awaits Aslan Karatsev after he beat Ugo Humbert in straight sets in what was the Russian's debut appearance at the tournament.

Dan Evans and John Isner were among the other players to secure progress on Monday.

Denis Shapovalov relished feeling much better on court as he impressively bounced back from two consecutive defeats to win at the Madrid Open.

The number 11 seed brushed aside the challenge of Dusan Lajovic on Sunday, winning 6-1 6-3 in the first round.

Shapovalov had suffered disappointment on Thursday when he was knocked out in the second round of the Estoril Open, an event where he was the number one seed.

He has not reached the quarter-finals in his previous two ATP Tour events but won 90 per cent of his first-serve points against Lajovic, hitting 21 winners to his opponent's five.

"Just definitely felt a lot better - I felt very good on the court," Shapovalov said after a 63-minute win in which he did not lose serve. 

"I'm just happy to get the first win.

"Not much can change in the span of a couple of days, but Madrid is a place where I have had a lot of success, from back in juniors to making semis here in the Masters [1000 event] and finals of Davis Cup.

"It's just a place where it kind of feels like home to me and I just feel so comfortable." 

Shapovalov will face Alexander Bublik – who saw off Marton Fucsovics in straight sets – in round two.

Tommy Paul, meanwhile, will play Andrey Rublev after defeating Pedro Martinez.

In the only match of the day to go the distance, Australian Alex de Minaur battled back to triumph 4-6 7-5 6-1 against Jaume Munar.

He will play either Lloyd Harris or Grigor Dimitrov, who are scheduled to do battle on Monday.

Naomi Osaka suffered a shock second-round exit to Karolina Muchova at the Madrid Open, but there was no such trouble for Simona Halep as she held off Zheng Saisai.

Second seed Osaka was playing just her second match on clay since the 2019 French Open due to injury issues and became the latest big name to fall at the hands of Muchova.

The world number 20, who had already defeated two top-five players this season, prevailed 6-4 3-6 6-1 in a time of one hour and 49 minutes in the Spanish capital.

Osaka has now lost two of her last three matches, having been eliminated from the Miami Open quarter-finals by Maria Sakkari at the end of March.

"I think today for me it was quite different from the last time I lost in Miami, and I actually think I played much better here, so I'm very happy about that," Osaka said.

"I think what I can take away from this is that I tried my best throughout the entire match. I think tennis-wise, I felt I was too defensive in the first set.

"I wouldn't say I’m happy that I lost, but I think I learned a lot. So that's all I can hope for."

Two-time champion Halep has yet to drop a set in this year's tournament after seeing off unseeded opponent Zheng 6-0 6-4.

Halep took nine games in a row at the start of the match but, like in her opening-round win over Sara Sorribes Tormo, she had to hold off a late surge from her opponent to advance.

Next up for Halep is a last-16 showdown with Elise Mertens, who beat Elena Rybakina 7-6 (7-4) 7-5 in the last of Sunday's matches.

Fifth seed Aryna Sabalenka safely advanced earlier in the day thanks to a 6-3 6-3 win against Daria Kasatkina, while Sakkari beat Anett Kontaveit 6-3 6-1.

Sabalenka was on course to face Victoria Azarenka for a place in the quarter-finals, but the Belarussian withdrew from her match with Jessica Pegula because of a back injury.

Elsewhere, Jennifer Brady, who knocked out fellow American Venus Williams in the first round, eased past Jelena Ostapenko 6-2 6-1.

Brady faces a tricky test in the next round with Anastasia Pavlyuchenkova, who defeated sixth seed Karolina Pliskova 6-0 7-5, seeking another scalp.

Ash Barty overcame Tamara Zidansek and her own disjointed performance to reach the third round of the Madrid Open on Saturday.

The Australian triumphed 6-4 1-6 6-3 after nearly two hours on court to extend her winning streak on clay to 13 matches.

Barty will face reigning French Open champion Iga Swiatek in the next round, the 19-year-old having eased past Laura Siegemund 6-3 6-3 in a contest where she failed to take 10 match points before getting over the line.

Barty endured a more troubled contest with Zidansek, landing just 51 per cent of her first serves.

Zidansek lost the opener after a wayward forehand at 4-4 but was authoritative in the second as she won a set against a top-10 player for the first time.

However, a series of errors early in the decider allowed world number one Barty to open up a lead she did not relinquish. Barty was champion at Roland Garros in 2019 but skipped last year's Paris grand slam, so the clash with Swiatek will pit together the two most recent French Open winners.

"[It was] a really tough match," Barty said after edging out Zidansek. "I felt my margins were a little bit off. I made a lot of errors. I think I was missing in the right way, but still just a foot or two here or there makes a big difference. I felt like there were probably too many loose ones for me today.

"I don't think there was a lot in it by any means. We had a lot of close games in the first set, early in the second set. In the third, as well, there were a lot of close games. I think the response early in the third was good. I was a bit more aggressive, was able to bring the match back on my terms."

Petra Kvitova set up a meeting with Veronika Kudermetova – who knocked out defending champion Kiki Bertens – after overcoming long-time rival Angelique Kerber 6-4 7-5.

Kerber got the opening break in each set, only to drop serve in the next game, with Kvitova ultimately rewarded for powerful hitting as she ended the contest with 33 winners to her opponent's 14.

"I served very well, especially in the important points," said Kvitova, who leads the head-to-head record 8-6. "I think we really played very well. She even served very well, as well. It was tough to attack her serve."

Fifteenth seed Johanna Konta suffered a straight-sets loss to Anastasija Sevastova, while Ons Jabeur fought back to beat Sloane Stephens.
