Naomi Osaka secured a long-awaited victory over a top-10 opponent after dispatching Jelena Ostapenko at the US Open on Tuesday.

World number 88 Osaka scored a 6-3 6-2 victory against Ostapenko for her first top-10 win in four-and-a-half years.

Osaka has now won 23 of her 28 matches at the US Open, at an 82% win ratio, which only Bianca Andreescu (86%) can better among current players with 10 or more main-draw matches at the tournament.

The four-time major winner was reduced to tears after downing the 10th seed in New York.

"I was trying not to cry when I was walking out too," Osaka said in her on-court interview. "I remember last year I was watching Coco [Gauff] play and I so badly wanted to step on these courts again and I didn't know if I could.

"I didn't know athletically, physically if I was able to. Just to win this match and just to be in this atmosphere means so much to me, so thank you."

Osaka, who won 39 of her 50 service points and held her serve throughout, needed three match points to move into the second round.

"I mean it was stressful, she was hitting some really good shots and I just told myself like, keep going, keep fighting for every point and maybe you'll have an opportunity," she added. 

"Eventually I did but then I looked up and then I saw so many faces so I was like, woah."

The unseeded Karolina Muchova awaits on Thursday for the Japanese star after her first-round triumph.

Aryna Sabalenka is through to her second Italian Open semi-final after a straight-sets victory over Jelena Ostapenko on Wednesday.

The Belarusian, who recovered from a lower back injury sustained in her previous match against Elina Svitolina, breezed through 6-2, 6-4 after just 72 minutes on the court.

Sabalenka broke her serve in the third and fifth games, with Ostapenko opening the door with two double faults, while a single break in the seventh game settled the second set.

The second seed almost let it slip with her only double fault but came back with two big serves to close out the win.

Sabalenka will face Danielle Collins or Victoria Azarenka in the semi-final on Friday. 

Data Debrief: Top 10

Sabalenka (10) has become only the second player to reach 10 or more WTA-1000 semi-finals since the start of the 2020 season, along with Iga Swiatek (16).

With Sabalenka joining Swiatek and Coco Gauff, it is the first time the WTA’s top three players have reached the semi-final at the same WTA event since Roland Garros in 2013 – excluding the WTA Tour Finals.

Sabalenka has spent the most time out on the court in WTA clay events in 2024, with this match bringing her up to 25 hours and 34 minutes.

Defending champion Elena Rybakina has been forced to withdraw from the Italian Open due to illness.

Rybakina has enjoyed a fine start to 2024, boasting a 30-5 record and capturing three WTA titles to match Iga Swiatek for the most of any player on the tour.

The 2022 Wimbledon champion won her second WTA 1000 title in Rome last year, defeating Swiatek and Jelena Ostapenko en route to the final, which she won by virtue of a walkover after taking the opening set, due to an injury to Anhelina Kalinina.

The Kazakhstani was set to open her title defence against Irina-Camelia Begu on Friday, but lucky loser Oceane Dodin took her place after she felt too unwell to play.

The world number four said: "Unfortunately I do not feel well enough to compete. I have such good memories from last year and was looking forward to defending my title.

"Rome is so special to me, and I look forward to being back next year to reclaim my title and play in front of the Italian fans."

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.

Coco Gauff became the first American teenager since Serena Williams in 2001 to reach the semi-finals of the US Open.

The 19-year-old dropped just two games as she blitzed Jelena Ostapenko 6-0 6-2 inside Arthur Ashe Stadium.

Latvian Ostapenko, the 20th seed, had blown the women’s draw wide open when she knocked out defending champion and world number one Iga Swiatek in round four.

But she was unable to take advantage of her own handiwork as Gauff raced away with the first set in only 20 minutes.

Ostapenko made more of a contest of it in the second set, finally managing to hold serve at the fifth attempt.

But Gauff completed the job in an hour and eight minutes to reach the last four of her home grand slam for the first time.

“It feels great, I’m so happy,” she said. “Last year I lost in the quarter-finals and I wanted to do better. There’s a long way to go but I’m happy and ready to go back to work.

“Honestly, I didn’t feel comfortable the whole match, even on match point. I know the game she plays. It’s really tough against her – you can’t really be aggressive. She’s a top player and she’s had a great tournament.

“There’s a saying in basketball that ‘defence wins games’. It doesn’t always work in tennis but today that was the case.”

Gauff will face the winner of Tuesday night’s match between Sorana Cirstea and Karolina Muchova in the last four.

Iga Swiatek’s reign as US Open champion, and world number one, was ended by her nemesis Jelena Ostapenko.

The 22-year-old Pole had not dropped a set on her way to the fourth round, but she had never beaten Ostapenko in three previous career meetings.

Swiatek took the first set with relative ease but then Ostapenko’s sledgehammer of a forehand started finding its mark to level the match.

A one-sided final set saw former French Open champion Ostapenko triumph 3-6 6-3 6-1.

Swiatek’s defeat means that Aryna Sabalenka of Belarus will take over as world number one after the tournament.

Ostapenko will face Coco Gauff in the quarter-finals after the teenager ended the grand slam comeback of mother-of-two Caroline Wozniacki.

The 19-year-old came from a break down in the first and third sets to win both and complete a 6-3 3-6 6-1 victory.

Wozniacki’s return has been one of the stories of New York this year, having come out of retirement after more than three years and two children later.

The 33-year-old former world number one has looked as though she has never been away, but a fired-up Gauff proved just too strong in the deciding set.

Wozniacki got off to a dream start with a break in the first game and a 2-0 lead.

But Gauff quickly got back on the board, levelling at 3-3 before going on to clinch the first set without dropping another game.

Wozniacki cranked up the pressure in the second and Gauff started feeling it as her suspect forehand began to misfire and she was broken for 5-3 as the Dane levelled the match.

Gauff looked uncomfortable as she dropped serve again at the start of the decider, but after pointedly ignoring the advice of coach Brad Gilbert, the wound-up American began firing backhand winners as if they were going out of fashion.

She reeled off the next six games to clinch the victory and let out a loud scream of triumph after converting match point.

“Definitely getting it to 2-1 (in the third set) was the turning point,” said Gauff.

“I got broke and I showed I was still in the match. I started to go for my shots.

“Caroline, it’s like she’s never left, the level she played was amazing. It’s weird because I grew up watching Caroline and when she won the Australian Open, so to be on court with her today was an honour.

“She definitely gets to a lot of balls. I felt a bit like I was playing myself. I knew I had to play aggressive and go for my shots. In some moments I miss but I was happy I could get back and refocus.”

It will be the fifth grand slam quarter-final of Gauff’s still-fledgling career and her second at Flushing Meadows.

“I’ve been in this position before,” she added. “And I think I have confidence in myself that I can go even further.”

Jelena Ostapenko won her second title on grass with victory over Barbora Krejcikova in the final of the Rothesay Classic in Birmingham.

In a battle of the top two seeds, it was the second seed who came out on top, with Ostapenko triumphing 7-6 (8) 6-4.

It was the Latvian’s first title since Dubai last February and her first on grass since Eastbourne in 2021.

Ostapenko clinched a very tight first set on her fourth set point in the tie-break after saving one chance for Krejcikova and moved to the brink of victory at 5-1 in the second set.

Czech Krejcikova, who will return to the top 10 on Monday, threatened a comeback, winning three games in a row, but Ostapenko made it across the line.

“She’s a really great player and congrats to her and her team,” said the 26-year-old, who has survived several close battles this week.

“I was really close from 5-1 to 5-4 but then I managed somehow and I’m really, really happy about it. I was fighting every match. I played five great matches, this was the only match in two sets. It’s a great preparation for Wimbledon and there’s still a couple of things I can do better.”

Krejcikova, who was playing her first final on grass, did not drop a set until the final and felt losing the first-set tie-break was crucial to the outcome.

“She’s playing well,” said the top seed. “I’m disappointed but that’s tennis. (The tie-break) was maybe the key to the match because when you play the first set that long and you are up, down, up, down all the time – I was very unfortunate.

“I definitely had a great week. It was really nice to be here, I really enjoyed it. It’s special to play on a centre court and to enjoy the support. I’m definitely looking forward to coming back.”

Aryna Sabalenka is through to the round of 32 at the Madrid Open after beating Sorana Cirstea 6-4 6-3 on Thursday.

It was an ominous start for Cirstea, being broken to love in the opening game, but she stuck with second seed Sabalenka and broke back, before ultimately being pipped to the first set by the impressive Belarusian.

The key was on break points, with Sabalenka claiming all five that she won against the Cirstea serve, while saving six of eight on her own as she ultimately eased to victory.

Sabalenka now has 26 wins on clay in the WTA since 2021, with only Ons Jabeur (37), Iga Swiatek (34), Paula Badosa (31) and Coco Gauff (28) having more during this time.

Gauff also advanced after a routine 6-4 6-1 win over Irene Burillo Escorihuela, making the sixth seed in Madrid the first player to win 35 WTA-1000 main draw matches as a teenager since 2009.

Ninth seed Maria Sakkari defeated Arantxa Rus 6-4 6-4 and fifth seed Caroline Garcia also had few problems against Yulia Putintseva, winning 6-3 6-4.

However, it was not a good day for 10th seed Petra Kvitova, who was beaten 7-6 (11-9) 6-1 by Jule Niemeier, while 13th seed Beatriz Haddad Maia also lost, 7-6 (8-6) 6-3 to Mirra Andreeva and 20th seed Donna Vekic was eliminated in straight-sets by Rebeka Masarova.

Jelena Ostapenko took just 61 minutes to get past Linda Fruhvirtova 6-0 6-3, and will face 14th seed Liudmila Samsonova next, who did not take much longer to see off Maryna Zanevska 6-2 6-3.

There were also wins for Elise Mertens, Badosa, Camila Osorio, Shelby Rogers, Mayar Sherif, Magda Linette and Irina-Camelia Begu.

Ons Jabeur forged a comeback win over Jelena Ostapenko to get her Stuttgart Open campaign off to a flying start.

Jabeur endured an injury-hit start to 2023 but bounced back with a victory in Charleston and made it six wins on the bounce by overcoming Latvian Ostapenko 1-6 7-6 6-3 on Wednesday.

Next up for Jabeur is a potential quarter-final tie with Elena Rybakina – a rematch of last year's Wimbledon final.

Rybakina, who won the Indian Wells Open in March, came up trumps on that occasion, fighting back to win 3-6 6-2 6–2.

The Kazakh, seeded sixth, overcame German Jule Niemeier 7-5 6-3 in the round of 32 and will now face Beatriz Haddad Maia in the last 16.

World number two Aryna Sabalenka also booked her progression to the last eight, beating 2021 French Open champion Barbora Krejcikova 6-2 6-3.

Coco Gauff, meanwhile, claimed her first victory in Stuttgart as she overcame a tough test from Veronika Kudermetova.

Gauff, the world number five, was taken to a deciding tie-break but ultimately prevailed 6-2 4-6 7-6 (7-3). The American will face Anastasia Potapova in the next round.

Former world number one Karolina Pliskova defeated Maria Sakkari in straight sets in Wednesday's other encounter.

Paula Badosa believes she can break back into the world's top three after cruising past Daria Kasatkina at the Porsche Tennis Grand Prix, where Emma Raducanu crashed out on Tuesday.

Seventh seed Kasatkina had no answers in Stuttgart as she fell to a 6-1 6-1 defeat against Badosa, who recorded the ninth top-10 victory of her career and first in exactly 12 months.

Badosa has won 29 clay-court matches in the last three seasons – only Ons Jabeur (35) and Iga Swiatek (30) have won more – but the Spaniard had to enter this tournament as a wildcard.

The 25-year-old was as high as second in the world last year but has fallen to 31st, and she outlined her goal to reach the top once more after her first-round win set up an all-Spanish meeting with Cristina Bucsa.

When asked about her ambitions to return to the world's top three, Badosa said: "That's what I'm working on every day. That's one of my goals – I want to be back on the top.

"I like to play big matches, I like to be in the last rounds of the tournaments. I still know I have that level. I still know I was that player. I still believe in myself, and I hope I'm back there very soon."

Jelena Ostapenko eased into the second round with similar dominance after downing Raducanu 6-2 6-1 in just 58 minutes, teeing up a meeting with world number four Ons Jabeur on Wednesday.

Latvian Ostapenko powered 19 forehand winners and went unbroken, acknowledging in her on-court interview that familiar aggression was key to her success in the battle of two one-time grand slam winners.

"I knew against her the main thing was to step in the court," said former French Open winner Ostapenko. "I missed some balls, but I tried to be aggressive all the time when it was possible.

"Just try to take the ball early, don't give her many chances. And finally, I'm back on clay, my favourite surface."

Barbora Krejcikova was another straight-sets winner, scoring a 6-2 6-0 triumph over Liudmila Samsonova, with the reward for the 2021 Roland Garros champion being a tricky clash against second seed and Australian Open winner Aryna Sabalenka.

There was no such ease for Anastasia Potapova in a battling 6-3 3-6 7-6 (7-4) victory over Petra Martic, the Russian's ninth third-set win in 2023 – no WTA Tour player has managed more.

Tatjana Maria overcame Ylena In-Albon 6-2 4-6 7-6 (7-4) in another enticing clash, while Beatriz Haddad Maia advanced after Martina Trevisan was forced to retire when trailing 7-5 1-1 due to a right thigh injury.

Last week's Indian Wells Open champion Elena Rybakina has extended her winning streak to 10 matches after defeating Paula Badosa 3-6 7-5 6-3 in Saturday's Miami Open third round.

Kazakhstan's Rybakina, who is also the reigning Wimbledon Champion and Australian Open finalist, got the better of Badosa for the second time during her current run, also eliminating her from Indian Wells. 

The 23-year-old has to be considered one of the favourites to go all the way, having knocked off world number one Iga Swiatek and world number two Aryna Sabalenka to lift the trophy in California.

Rybakina will meet Belgium's Elise Mertens in the fourth round after she beat Croatia's Petra Martic 6-4 6-3.

Meanwhile, the biggest upset of the day was delivered by Russia's Anastasia Potapova, bouncing sixth seed Coco Gauff 6-7 (8-10) 7-5 6-2.

Potapova, who has never won a tournament above the WTA 250 level, will face China's Zheng Qinwen for a spot in the quarter-finals after her three-hour 5-7 7-6 (7-5) 6-3 triumph over Liudmila Samsonova.

Latvia's Jelena Ostapenko, the 24th seed, eliminated Brazilian 13th seed Beatriz Haddad Maia 6-2 4-6 6-3, while 20th seed Magda Linette of Poland knocked out Belarusian 14th seed Victoria Azarenka 7-6 (7-3) 2-6 6-4.

Unseeded American Clare Liu went down 4-6 7-5 6-4 against Italy's Martina Trevisan, but third seed Jessica Pegula will continue to fly the flag for the United States after advancing 6-1 7-6 (7-0) in her all-American showdown with Danielle Collins.

Jessica Pegula and Coco Gauff headlined a great day for the Americans at the Miami Open as they both advanced into the third round on Thursday.

Pegula, who is the second-highest seed remaining in the field after Iga Swiatek's withdrawal, had no issue dispatching Canada's Katherine Sebov 6-3 6-1 in just 66 minutes.

Gauff, the six seed, followed suit as she raced to a 6-4 6-3 win over Canadian Rebecca Marino in just 73 minutes.

Florida's own Danielle Collins thrilled her hometown crowd with a 7-6 (7-3) 6-2 triumph against Bulgaria's Viktoriya Tomova, and rising 22-year-old talent Clare Liu made it a perfect 4-0 sweep for the USA representatives by defeating Julia Grabher 6-4 6-3.

Last week's Indian Wells Open champion Elena Rybakina was made to work in her 7-5 4-6 6-3 win over Anna Kalinskaya, while an even more gruelling effort was required in Paula Badosa's two-hour-and-52-minute 7-6 (7-2) 4-6 6-2 result against Laura Siegemund.

The top seed to fall on Thursday was eighth seed Daria Kasatkina, as she won the first set before going down 4-6 6-2 6-2 against Elise Mertens.

Liudmila Samsonova, the 12th seed, made light work of Viktorija Golubic in a 6-1 6-1 drubbing, and 22nd seed Jelena Ostapenko prevailed 6-3 6-4 against Mirjam Bjorklund.

Ostapenko will next play 13th seed Beatriz Haddad Maia after she won a strange back-and-forth contest 7-6 (7-4) 0-6 6-0 over Tereza Martincova.

Third seed Jessica Pegula rallied back from a set down for the second straight match to advance into the final 16 with a 3-6 6-4 7-5 victory over 26th seed Anastasia Potapova.

Potapova won the first set in 39 minutes, claiming the only break of the frame in the sixth game, but Pegula responded by breaking immediately in the second.

Despite squaring the match up, the American trailed 3-1 in the third set, only to fight back again and triumph in two hours and 17 minutes.

Pegula will face 15th seed Petra Kvitova after she won a seesawing three-set contest over 24th seed Jelena Ostapenko, 0-6 6-0 6-4.

Ostapenko won the first six games, before Kvitova won the next 10, only for the Latvian to hit back and claim the next four, squaring up the deciding set at 4-4. But two-time Wimbledon champion Kvitova held her nerve and won the final two games for victory.

World number two Aryna Sabalenka progressed to the final 16 via walkover after her third-round opponent Lesia Tsurenko withdrew.

The 2023 Australian Open champion will take on 2021 French Open winner Barbora Krejcikova after she toppled Wang Xin 6-2 6-7 (1-7) 6-2.

Seventh seed Maria Sakkari secured victory in a two-and-a-half-hour third-round clash with Anhelina Kalinina, winning 3-6 6-2 6-4.

Two-time major runner-up Karolina Pliskova won 6-1 7-5 over Veronika Kudermetova, progressing into the last eight to face Sakkari.

Sixth seed Coco Gauff, who turns 19 on Monday, eased past 54th-ranked fellow teenager Linda Noskova 6-4 6-3 in one hour and 19 minutes.

Sweden's Rebecca Peterson continued her resurgent form with a 3-6 6-3 6-1 win over Jil Teichman, setting up a clash with Gauff.

Aryna Sabalenka showed exactly why she is ranked second in the world as she dominated her opening match of the Indian Wells Open on Friday against Evgeniya Rodina.

Belarus' Sabalenka needed just 66 minutes to defeat the Russian 6-2 6-0, taking advantage of her first-round bye to book her spot in the third round against Ukraine's Lesia Tsurenko.

Tsurenko had to come from behind against the in-form Donna Vekic, fresh off her Monterrey Open title last week, but that big effort may have had the Croatian with heavy legs as she ran out of steam 2-6 6-2 6-2.

It was a strong day for the Ukranians as 27th seed Anhelina Kalinina beat the Czech Republic's Linda Fruhvirtova 4-6 6-4 7-5, and she will next face Greece's Maria Sakkari.

Sakkari, the seventh seed, had to deal with adversity after a poor first set against Shelby Rogers, coming back to win 2-6 6-4 6-0.

Olympic gold medallist Belinda Bencic lost her Swiss showdown against Jil Teichmann 3-6 6-3 6-3, while Veronika Kudermetova got the better of her Russian compatriot Anna Blinkova 6-3 6-4.

The second-highest ranked American in the field, Coco Gauff, had no issues dispatching Spain's Cristina Bucsa 6-2 6-4. But it was tougher work for America's top hope Jessica Pegula as she was pushed all the way by recent Merida Open champion Camila Giorgi, before prevailing 3-6 6-1 6-2.

Iga Swiatek continued her ruthless form as she progressed with ease to the WTA Dubai Tennis Championships third round on Tuesday.

The world number one cruised to a 6-1 6-1 triumph over 2021 US Open finalist Leylah Fernandez, just three days after winning the Qatar Ladies Open in Doha.

That marked Swiatek's 41st main-draw victory in WTA 1000 events in just her 53rd outing, only Serena Williams and Maria Sharapova (52 each) have won more than 40 such matches in fewer attempts.

The 21-year-old has won her last 35 hard-court matches against opponents ranked outside the world's top 30, though Swiatek said she had to adapt against Canada's Fernandez.

"It wasn't that easy for sure. It was much tougher than the score said," said Swiatek, who will look to make the fourth round for the first time in Dubai when she faces Liudmila Samsonova.

"In the second set ... I needed to go a level up. I didn't have much time to get used to the conditions, but I'm just happy I could play solid tennis."

Jessica Pegula, the third favourite at the tournament, defeated Viktoriya Tomova 6-2 5-7 6-1 to set up a third-round battle with Ana Bogdan, who overcame Shelby Rogers 7-6 (7-3) 6-3.

Fifth seed Coco Gauff coasted past Aliaksandra Sasnovich with a 6-0 6-4 victory, teeing up a meeting with Elena Rybakina, who slammed six aces in a 7-5 6-2 defeat of Marie Bouzkova.

World number two Aryna Sabalenka, who defeated Rybakina at this year's Australian Open final, made light work of lucky loser Lauren Davis in a straight-sets rout as she claimed her 12th straight win in 2023.

Dubai's defending champion Jelena Ostapenko will be the next challenge for Sabalenka after defeating 17-year-old Linda Fruhvirtova for her seventh straight win at the event.

Barbora Krejcikova saved four match points en route to a 6-4 4-6 7-5 win over seventh seed Daria Kasatkina and will meet Karolina Pliskova next after she downed sixth favourite Maria Sakkari in straight sets.

Belinda Bencic and Marta Kostyuk played out the match of the day as the former claimed a 6-7 (7-9) 7-6 (7-5) 6-4 triumph, with that clash taking three hours and 27 minutes – the second-longest on the WTA Tour this year.
