Amanda Anisimova celebrated her fifth career top-10 win by beating Aryna Sabalenka again at the Madrid Open.

The 20-year-old American would have headed into Thursday's match-up full of confidence having also defeated the world number four in Charleston earlier this month.

And again Anisimova came out on top, this time at a tournament where Sabalenka was the defending champion.

Sabalenka is now 0-4 against Anisimova, losing three times on clay, with this the underdog's first ever victory in Madrid.

A 6-2 3-6 6-4 triumph was sealed in an hour and 55 minutes, with Anisimova relishing the opportunity to take on one of the sport's foremost stars once more.

"It's always enjoyable to accept the challenge, even when it's a tough match, and push yourself and see how far you can go," Anisimova said.

"I enjoy these matches, even though they're very tough – especially when you get to win them."

While Anisimova can look forward to facing Petra Martic in round two, hers was not the only upset win, with Karolina Pliskova and Jelena Ostapenko also ousted.

Pliskova lost in straight sets to fellow Czech Marie Bouzkova, as Ostapenko went down in three to Ekaterina Alexandrova.

Simona Halep and next opponent Paula Badosa both came through unscathed, though, as did Belinda Bencic, Coco Gauff and Ons Jabeur.

Jabeur's 11-9 first-set tie-break success against Jasmine Paolini was the closest any of that quintet came to dropping a set on day one.

Emma Raducanu hailed Torben Beltz as "one of the nicest people I've met", despite deciding to split from the German coach.

The US Open champion parted company with Beltz on Tuesday after just five months together.

The duo began working together in November but have now split as the world number 11 plots the way forward ahead of the French Open and Wimbledon.

"Torben is a great guy. I really enjoyed my time with him on and off the court," Raducanu said while preparing for the Madrid Open on Wednesday. 

"He is one of the nicest people I've met, so obviously it was a tough one to split with someone like that.

"But I feel like right now I'm very comfortable with my current training. I'm feeling very confident in what I'm doing and how I'm working.

"I feel like over the last few weeks it's definitely become more apparent and especially as I've spent more time on the tour playing more matches against these top opponents, that I kind of understand what I feel like I need more of.

"I think Torben has been great for me because when I wanted someone with tour experience, I think for my first six months on the tour, it was very valuable."

The 19-year-old has recently enjoyed her best week of the season, winning back-to-back matches at the Stuttgart Open, before putting in a respectable performance in defeat to world number one Iga Swiatek.

Beltz is the third coach to move on from working with Raducanu in the last 12 months. She swapped Nigel Sears for Andrew Richardson, who worked with her at the US Open, before deciding to bring in Beltz, who previously worked with Angelique Kerber and Donna Vekic.

Raducanu is scheduled to face Czech player Tereza Martincova on Friday in Madrid and will be assisted by Iain Bates at the tournament, the long-serving head of women's tennis at the Lawn Tennis Association.

Naomi Osaka believes teen tennis star Carlos Alcaraz has rejuvenated excitement around the ATP Tour, while she labelled Rafael Nadal as an inspiration ahead of the Madrid Open.

Alcaraz needed just 67 minutes to defeat Spanish compatriot Pablo Carreno-Busta 6-3 6-2 at the Barcelona Open last Sunday, claiming his third title of the season after wins in Rio de Janeiro and Miami.

The 18-year-old has surged to a career-high ninth in the world rankings, Alcaraz becoming the youngest player to crack the top 10 since fellow Spaniard Nadal achieved that feat at the same age in 2005.

Coincidentally, Nadal also broke into the top 10 after success on the same day (April 25) at the Barcelona Open and the pair will next compete in Madrid in the ATP 1000 Masters event, which starts on Sunday.

Former women's world number one Osaka revealed she is keen to cast an eye over the duo in the Spanish capital, where she faces a qualifier in the first round, as she hailed the impact Alcaraz has had.

"I feel like he's genuinely made everyone excited about the ATP and I haven't seen that in a very long time," Madrid Open wildcard Osaka said of Alcaraz, who boasts an impressive 23-3 record in the 2022 season.

"I'm not even really thinking about his age, like every time someone brings up his age, I'm like, 'Oh wow, I forget, that's so cool'.

"I think just his game style, just how pumped he is, how I feel like I'm watching him learn with every tournament.

"I don't know what his ranking was last year here, but I've watched almost every tournament that he's played, the US Open when he played [Stefanos] Tsitsipas and just to see the growth I think is really exciting for everyone."

Osaka has won all four of her grand slam titles on hard courts, but the 24-year-old will now search for clay-court success in Madrid.

Japanese Osaka has spent time preparing in Majorca, where she has used 13-time French Open winner Nadal as an inspiration, given his expertise on clay courts.

"I think I stole one of the things that he did and I've been practising it recently," she said of Nadal, who holds the record for most men's grand slam titles with 21 major triumphs to his name.

"It'll either go really good or really bad. There's like no in between. But I think as I've been doing it, it's been going pretty well.

"Honestly I've been wanting to watch the really good clay-court players practice because I feel like I'm the type of person that learns really fast if I see it up close and honestly it's a bit of a waste to have all these really good professional tennis players and not watch them."

Osaka suffered a second-round exit at the Indian Wells Masters in March, impacted by abuse from a heckler in the crowd, but rebounded by making the final in Miami, where she lost to world number one Iga Swiatek.

However, Osaka is looking to use the experience at Indian Wells, where she was reduced to tears by a spectator reportedly shouting "Naomi, you suck", as a learning curve to develop.

"I feel like there are a lot of moments in my career that are like extremely sad for me at the time but I kind of later look back on it and I think to myself, 'Well that really made me grow as a person, and even though I really hated the experience, I'm glad it happened to me'," she added.

"For me, that's one of those moments. I wish it didn't happen, but also I'm glad that it did.

"I feel like it prepared me for a lot of things that may or may not happen, but it's kind of like one of those things you have in your back pocket as experience."

World number one Iga Swiatek will not play the Madrid Open after suffering a shoulder injury.

The Pole is in stunning form, having won four titles in a row after prevailing in the Stuttgart Open last time out.

Before that, the 20-year-old – whose winning streak stands at 23 matches – had lifted the trophy at the Qatar Ladies Open, Indian Wells and Miami Open.

"After intense last weeks and winning four titles in a row, it's time to take care of my arm that has been fatigued since the Miami Open and I haven't had a chance to handle it properly," Swiatek, the 2020 French Open champion, wrote in a statement posted to Twitter.

"I need a break from playing so intensively in order to treat my arm well and that's why, unfortunately, I have to withdraw from the Mutua Madrid Open. 

"My body needs rest. I'm going to take some time to prepare for Rome and Paris. See you soon there.

"Hopefully, I will play in Madrid many times in the future – I'm looking forward to it."

Swiatek was due to be top seed in the Spanish capital.

Rafael Nadal plans to make his return from injury in his homeland at the Madrid Open next week.

Nadal has been sidelined since suffering a cracked rib during the Indian Wells Masters last month.

The 21-time grand slam champion on Tuesday revealed he has decided to make his ATP Tour comeback at the Caja Magica.

He posted on social media: "Despite preparation being difficult, I really want to play at home since the opportunities are few.

"[I want] To try to do it in the best possible way. See you in Madrid."

Taylor Fritz consigned Nadal, a five-time champion at the Madrid Open, to his first defeat of the year in the final at Indian Wells.

The Australian Open champion was visibly struggling to breath during that match after sustaining the injury during a semi-final victory over fellow Spaniard and heir apparent Carlos Alcaraz. The 35-year-old's 2022 record so far stands at 20-1.

Nadal's return is set to make his comeback just three weeks before he will be hoping to start his bid to win a 14th French Open title at Roland Garros.

Matteo Berrettini could miss the French Open after the world number six was forced to withdraw from three tournaments as he continues to recover from minor hand surgery.

The Italian progressed to the Wimbledon final in 2021 and started the new season in encouraging fashion as he reached the Australian Open semi-finals, where he was well-beaten by eventual winner Rafael Nadal.

However, the 25-year-old has seemingly struggled from then on, with his next best performance coming in Rio – where he made the last eight – as he limped to a 9-6 record so far in 2022.

Further difficulties followed for Berrettini after he sustained an injury to his right hand late in March, forcing him to withdraw from the Miami Open before undergoing a "minor operation".

Berrettini provided another update on Instagram on Thursday, revealing he would not feature at the Monte-Carlo Masters, scheduled to start later this week, or the Madrid Open and Italian Open at the start of May.

The latter tournament in Rome begins just two weeks before the second grand slam of the year, leading to concerns that Berrettini may not feature at Roland Garros.

"UPDATE – following advice from the medical experts, my team and I have decided that it is crucial I do not put time pressure on my recovery process," he posted.

"We have therefore decided I should withdraw from the Monte-Carlo, Madrid and Rome tournaments to ensure I give myself the proper amount of time to return at my highest level.

"Withdrawing from these events, particularly Rome, was an extremely tough decision, however it is the right one to ensure many more years of competing at the highest level for the biggest trophies.

"Thanks very much for all the support. My recovery process is on track and I look forward to seeing you on-court soon."

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.

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.
