Irina-Camelia Begu came from a set down to defeat Sara Sorribes Tormo 3-6 6-3 6-4 to set up a final against Lucia Bronzetti at the Palermo Ladies Open.

A contest that lasted three hours and 12 minutes, finishing just 20 minutes shy of 2am local time, began well for Sorribes Tormo, with the fourth seed taking the opening set.

The Romanian came storming back in the second though and was forcing her opponent all the way back to the advertising curtain with a series of deep shots, while also impressing on her own serve, getting 90 per cent of her first serves in across the set.

Begu ultimately served out to take it 6-3 as the local time went past midnight, but there was plenty more to come as a third set that moved at a glacial pace in the early hours of Sunday morning kept the more dedicated fans in the stands away from their beds.

An hour after the second set had concluded, the score in the third was just 3-2 to Begu after the sixth seed forced a break against Sorribes Tormo, who was warned with a time violation during the game.

That seemed to be a turning point as one break became two, before the Spaniard broke back to initially frustrate Begu, only for the Romanian to serve out victory at the second time of asking.

She will face Bronzetti in Sunday's final after the world number 78 also came from behind to win her semi-final with compatriot Jasmine Paolini.

It was a remarkable turnaround considering Paolini won the opening set 6-0, with Bronzetti only winning 33 per cent of points on her own first serve compared to Paolini's 79 per cent on hers.

However, Bronzetti found several more gears in the second set, winning 83 per cent on her first serve this time, and she carried that form into the third, recovering brilliantly to take the match 0-6 6-3 6-3.

Anett Kontaveit cruised into the quarter-finals of the Hamburg European Open with a straight-sets win over Rebecca Peterson, while third seed Zhang Shuai was forced out of the Palermo Ladies Open through injury.  

World number two Kontaveit recorded a 6-3 6-2 victory over Peterson on the clay in Germany, setting up a last-eight meeting with eighth seed Andrea Petkovic. 

The Estonian's win was her third over Peterson and maintained her 100 per cent career record against Swedish opponents, taking her to seven such successes. 

Kontaveit was joined in the quarter-finals by fellow seeds Aliaksandra Sasnovich, who beat Aleksandra Krunic 6-3 6-2, and Maryna Zanevska, who downed Alexandra Cadantu-Ignatik 6-4 6-1. 

They will face off for a semi-final spot on Thursday, while Anastasia Potapova will meet 2021 French Open champion Barbora Krejcikova after beating Maria Carle in straight sets. 

At the Palermo Ladies Open, meanwhile, third seed Zhang withdrew from her last-16 clash with home favourite Jasmine Paolini before taking to the court, citing an unspecified injury. 

Fellow seeds Sara Sorribes Tormo and Anna Bondar both reached the quarter-finals with straight-sets wins, however, with the pair set to face off for a semi-final berth on Friday.  

Barbora Krejcikova beat Suzan Lamens in the opening round of the Hamburg European Open for her first victory on clay in over a year.

The third seed, who claimed a second Wimbledon women's double title this month, saw off qualifier Lamens 6-2 6-4 to reach the last 16.

Her most recent victory on a clay-court surface prior to Monday came at last year's French Open, winning both the singles and women's doubles titles at Roland Garros in 2021.

Last year's runner-up Andrea Petkovic is also through thanks to a 6-3 6-3 victory over Tamara Korpatsch and will now face Misaki Doi, who defeated Oksana Selekhmeteva.

At the Palermo Ladies Open, meanwhile, fourth seed Sara Sorribes Tormo battled back from a set down to overcome Ana Bogdan 2-6 6-4 6-2.

Third seed Zhang Shuai also avoided an upset as she secured a 7-6 (7-3) 7-6 (9-7) victory over Rebeka Masarova, while Irina Begu required three sets to beat Marina Bassols.

Serena Williams made a thrilling return to the WTA Tour as she and Ons Jabeur teamed up to win a nail-biting doubles contest at the Eastbourne International.

Czech player Marie Bouzkova and Spaniard Sara Sorribes Tormo provided stiff competition but eventually succumbed 2-6 6-3 13-11 as Williams grew in belief.

This was the first competitive match for 40-year-old Williams since abandoning her Wimbledon first-round clash against Aliaksandra Sasnovich last June, due to an ankle injury.

It was also her first doubles main-draw match on grass since she and sister Venus won the 2016 Wimbledon title, so she was understandably rusty in the early stages, while world number three Jabeur's nervousness about playing with Williams, which she spoke of after the match, was also evident.

Williams will be on a wildcard at Wimbledon next week, due to her ranking plummeting, as she chases what would be a record-equalling 24th grand slam singles title.

Her game looked sketchy early on, with a smash into the net handing over the second game, before she then blazed a volley over the baseline to concede the early break.

Her own serve was broken as Sorribes Tormo and Bouzkova snatched a 4-1 double-break lead in the opener, which they soon wrapped up.

Williams lost her footing on the grass midway through the second set, slipping over, but she was soon back up, with the contest becoming increasingly competitive.

Jabeur and Williams forged a 4-3 lead in the second set and then broke to force the match tie-break.

All-out assault from Williams brought up a first match point, but the American then rattled a backhand long after Jabeur failed to put away a volley at the net early in the rally.

Another match point slipped away as Jabeur netted from another great chance, but a drop shot from the Tunisian brought up a third, and this time Sorribes Tormo volleyed wide to herald a scream of delight from Williams.

"Oh my god, it was so fun to play with Ons," said Williams. "Our opponents played amazing. They played so well in that first set, they were jamming.

"We were just trying to stay in there after the first set, it was good though.

"I caught some fire behind me, so that's good; I needed that."

Naomi Osaka joined several other big names in falling to a second-round exit at the Madrid Open, although Emma Raducanu cruised to a routine straight-sets win over Marta Kostyuk.

Four-time grand slam winner Osaka crashed to a resounding 6-3 6-1 loss to Spain's Sara Sorribes Tormo, exiting her first tournament on clay since the 2021 French Open, where she withdrew citing mental health issues.

Osaka, who had posted an underwhelming 20-15 record on the surface prior to this week, looked uncomfortable throughout and appeared to struggle with a leg injury during a disappointing second set display.

The 24-year-old was not the only high profile player to be on the receiving end of a shock during a day of drama in the Spanish capital, as several of the competition's seeds failed to secure places in the last 16.

Another home favourite, Garbine Muguruza, fell to a resounding loss of her own as Anhelina Kalinina raced to a 6-3 6-0 victory over the seventh seed, while sixth seed Danielle Collins was thrashed 6-1 6-1 by Canadian Bianca Andreescu.

Fourth seed Maria Sakkari was the highest-ranked player in action, and although the world number five won the first set of her clash with Daria Kasatkina, the Greek eventually fell to a 3-6 6-3 6-1 loss, while 2021 US Open runner-up Leylah Fernandez went down 6-4 6-4 to Jil Teichmann.

One big name who did make comfortable progress, however, was Fernandez's US Open conqueror Raducanu, who eased to a 6-2 6-1 win over Kostyuk to set up a last-16 encounter with another Ukrainian in Kalinina. 

The 19-year-old, who has been quoted as saying she believes clay could prove to be her best surface in the future, was delighted with her victory and enjoying the tournament after dropping just one game in the second set.

"I'm definitely happy with my performance," Raducanu said on court. "Marta's a great opponent - I knew it was going to be a really tough battle. I went out there trying to be really aggressive and it paid off.

"It's my first clay court season and I'm really enjoying it. Madrid is such a cool city and it's got such a great vibe about it. I definitely want to try and stay here for as long as possible."

Elina Svitolina saw her hopes of delivering an emotional title for Ukraine ended by Camila Osorio in a tough quarter-final loss at the Monterrey Open.

Top seed Svitolina wore the yellow and blue colours of her home country, which has come under attack from Russia's military in the past fortnight.

However, the former world number three could not capitalise on a fast start, or a big lead in the deciding set, as she slipped to a 1-6 7-5 7-6 (7-5) defeat in two hours and 33 minutes.

Svitolina held a 4-1 lead in the third set, but 20-year-old Colombian Osorio recovered the double break to edge out the 2020 champion, sealing the win in a deciding tie-break.

That was the third tight three-set battle of the day, with Brazil's Beatriz Haddad Maia earlier scoring a 4-6 6-4 7-6 (9-7) win over Marie Bouzkova, and Nuria Parrizas Diaz achieving a 6-3 1-6 6-4 victory in an all-Spanish clash with Sara Sorribes Tormo.

Parrizas Dias will face Osorio in Saturday's semi-finals, while Haddad Maia faces a tussle with US Open runner-up Leylah Fernandez, who was a late-night 7-6 (7-4) 6-4 winner against China's Wang Qiang.

Sloane Stephens fought back from a set down to reach her first hard court semi-finals since 2018 as she defeated Daria Saville at the WTA Abierto Zapopan on Friday.

The 2017 US Open champion triumphed in two hours and 29 minutes over the Australian, winning 4-6 6-3 6-2 in Guadalajara.

Stephens, who will play Russian Anna Kalinskaya in the last four, had not reached a hard court semi since the 2018 WTA Finals.

But the American was forced to do it the hard way after losing the first set, saving nine of 13 break points across the match, with her ability to win second serve points proving key.

Colombian fourth seed Camila Osorio was bundled out in 80 minutes by Kalinskaya 6-4 6-1.

There was also a straight-sets win for Marie Bouzkova after she defeated third seed Sara Sorribes Tormo 6-4 6-1.

She will face Wang Qiang in the last eight, who proved too good for Slovakian Anna Karolina Schmiedlova 6-2 6-3.

France's Billie Jean King Cup defence ended at the hands of the Russian Tennis Federation, who will meet the United States in the semi-finals after Wednesday's play in Prague. 

Clara Burel put France on course for the 3-0 victory they needed to advance from Group A with a three-set victory over Ekaterina Alexandrova, but Anastasia Pavlyuchenkova outlasted Alize Cornet in the second rubber to ensure a new champion will be crowned. 

Pavlyuchenkova saved six of 10 break points and racked up an impressive 34 winners en route to a crucial 5-7 6-4 6-2 success against Cornet. 

"I'm so, so happy and so proud of myself because I think it was an incredible match. It was very good tennis but more importantly I think it was an amazing fighting spirit from both of us," said Pavlyuchenkova. 

"We were like two tigers. Nobody wanted to give the other anything and I think that's what matters. That's the sport we're playing." 

Veronika Kudermetova and Liudmila Samsonova comfortably defeated Cornet and Burel in the doubles to consign the reigning champions to a 2-1 defeat. 

The RTF will go up against the USA in the first semi-final, with the Americans comfortably seeing off Spain in the singles rubbers. 

Sloane Stephens bested Nuria Parrizas-Diaz 6-4 6-4 before Danielle Collins swept Sara Sorribes Tormo aside 6-1 6-0 in under an hour. 

Collins won 83 per cent of points behind her first serve and forced Sorribes Tormo into 24 errors during a resounding victory. 

Spain avoided a 3-0 defeat, though, with Aliona Bolsova and Rebeka Masarova beating Caroline Dolehide and CoCo Vandeweghe 6-3 6-4 in the doubles rubber. 

Olympic gold medallist Belinda Bencic eased to a straight-sets win over Sara Sorribes Tormo to maintain her good form and book a place in the Ostrava Open quarter-finals.

Third seed Bencic needed just 88 minutes to see off her 36th-ranked opponent as she made it 15 victories from her past 18 matches.

Czech wildcard Tereza Martincova is also through to the last eight on home soil after battling past French Open finalist Anastasia Pavlyuchenkova 7-6 (7-5) 7-6 (8-6).

Martincova is into her fifth quarter-final of the season and will take on number four seed Maria Sakkari, who saw off Jelena Ostapenko 6-4 6-2 earlier on Thursday.

Also through to round three is Elena Rybakina following a hard-fought 6-3 2-6 6-1 win over qualifier Magda Linette, while Jil Teichmann – who shocked former world number one Angelique Kerber in the previous round – advanced in three sets against Alison Riske.

She will face Petra Kvitova for a place in the semi-finals. 

Emma Raducanu came within one point of a sensational double bagel against Sara Sorribes Tormo and could face Ash Barty next at the US Open.

The 18-year-old Briton came through qualifying to make her Flushing Meadows bow this week.

And now Raducanu is remarkably into week two without dropping a set.

She saved her best performance yet for round three, winning 6-0 6-1 after passing up a match point on Sorribes Tormo's serve that would have sealed a flawless result.

Her place in the fourth round was a fine consolation for Raducanu, who reached the same stage at Wimbledon in July, then appearing in a grand slam main draw for the first time.

A match against Ajla Tomljanovic proved a step too far at the All England Club, but Raducanu may now get an opportunity to advance against another Australian.

If Barty beats Shelby Rogers later on Saturday, the world number one will face Raducanu next week – presumably far away from the Court 17 the teenager was consigned to on this occasion.

Given Sorribes Tormo beat Barty in straight sets in the first round of this year's Olympic Games, Raducanu should have nothing to fear.

"It's been two weeks in New York now," she told Prime Video. "And into the third week – I never thought I'd be here, but I'm just so, so excited."

Raducanu said of her latest triumph: "I was playing very well. I know Sara is an extremely tough opponent – she doesn't make a mistake, so you have to be on your game every single point.

"I had to work so hard, and there were some really, really long deuce games that could have gone either way, so I'm just really happy that I managed to maintain and stay on it and win in the end."

It was a far more comprehensive success than Raducanu was willing to admit, though, with the world number 150 having 11 break point opportunities to her opponent's zero.

Raducanu's blistering forehand averaged 92 miles per hour on serve, while she played 23 winners.

"Honestly, for this one, the plan was I had to hit through her, I had to hit the corners," she added. "If you trade against her, you're probably going to come out second best.

"I just took the game to her and hit more winners than errors today."

Naomi Osaka was never preordained to win gold at the Tokyo Olympics but it had felt that way until she ran into Marketa Vondrousova.

The surprising 6-1 6-4 loss that a lacklustre Osaka suffered on Tuesday could be explained away by the fact the 23-year-old had not played any competitive tennis since pulling out of the French Open at the end of May.

All the same, it was a major upset as world number 42 Vondrousova took out the highest remaining seed in the draw – the Japanese star who lit the Olympic cauldron on Friday.

Osaka's exit, after previous shock defeats for top seed Ash Barty and number three Aryna Sabalenka, has raised the prospect of a shock champion, just as occurred five years ago at the Rio Games when Monica Puig of Puerto Rico caused a sensation.

Now at the quarter-final stage, there is one former grand slam champion left in the field and two finalists at that level, but it really looks like anyone's title.

VONDROUSOVA SENSES AN OPPORTUNITY

It was remarkably straightforward for Vondrousova at Ariake Tennis Park, as she cruised through the opening set and soon reeled in Osaka's early break in the second.

Osaka saved two match points when serving to stay in the contest, but not a third, planting a backhand wide.

Considering Vondrousova reached the French Open final two years ago, in front of packed grandstands rather than the empty seats in Tokyo, it was no surprise she hesitated when asked whether this win over Osaka was the biggest of her career. It probably doesn't have that cachet, good a win though it was.

"Of course it's one of the biggest," Vondrousova said.

"Naomi is a great player, she has so many grand slams, so I knew it would be a tough match. But I'm just very happy with my play. I played amazingly in the first set, and then the second set was really tough. I'm just happy to be through.

"I think she was struggling a bit with my serving. Also, I use drop-shots very well. I'm just very happy with my game today."

She faces Spain Paula Badosa next and said: "It's very open now. I think every girl is playing really well. Now it's the quarter-final, so we'll see."

HAS SVITOLINA'S TIME ARRIVED?

A fixture in the top 10 over recent seasons, Svitolina has been unable to transfer her regular tour form onto the major stage on a consistent basis.

Maybe the Olympics will be a platform towards success on that stage, with Svitolina now the highest seed remaining in the draw, at number four. The Ukrainian is also on a high on the personal front, having married French tennis star Gael Monfils shortly before heading to Tokyo.

Two semi-finals, at Wimbledon and the US Open in 2019, have been her deepest runs in the majors, and this season has been one of diminishing returns, with a fourth-round run in Australia followed by a third-round Roland Garros exit and a round-two loss at Wimbledon.

Svitolina beat Maria Sakkari of Greece 5-7 6-3 6-4 on Tuesday, setting up a quarter-final against Italian Camila Giorgi who won 6-4 6-2 against Wimbledon runner-up Karolina Pliskova.

"I don't think I'm a favourite because there are lots of good players here and everyone is quite equal," Svitolina said.

A MUG SHOT?

Should Spain's Garbine Muguruza be considered the favourite from this point? With French Open and Wimbledon titles in her trophy room, Muguruza has shown she has what it takes to triumph on a big stage, and a clinical 6-4 6-1 win over Belgian Alison Van Uytvanck on Tuesday was just the job.

She goes on to face Elena Rybakina of Kazakhstan, who edged past Croatian Donna Vekic.

Belinda Bencic of Switzerland caused a surprise by ousting the in-form reigning French Open champion Barbora Krejcikova, springing a 1-6 6-2 6-3 win that means there will be no repeat of the Roland Garros final in the quarter-finals.

That had been on the cards, but Bencic will be the player who takes on Anastasia Pavlyuchenkova for a place in the final four.

Pavlyuchenkova scored an impressive 6-1 6-3 victory over Sara Sorribes Tormo of Spain, the player who knocked out Barty in round one.

Russian Olympic Committee's Pavyluchenkova is looking to harness the form that took her to a maiden slam final, describing her Paris run as "a great experience to have".

"But every week is a new week and this is a new event," said the 30-year-old. "The Olympic Games is a very special event. It's different. It's nothing like the others."

Camila Giorgi extended her strong run at the Viking International in Eastbourne as she dumped out top seed Aryna Sabalenka on Thursday.

The Italian had already beaten defending champion Karolina Pliskova en route to the last eight and pulled off another upset as she claimed a 7-6 (7-5) 0-6 6-4 win over Sabalenka.

Giorgi's bid for the third WTA Tour title of her career will now continue with a semi-final against Anett Kontaveit on Friday.

The Estonian also needed three sets to book her place, bouncing back from losing the opener to beat Viktorija Golubic 2-6 7-6 (7-2) 7-5.

Daria Kasatkina was unable to build on her win over fourth seed Iga Swiatek in the last round as she missed out on a spot in the semi-finals.

The Russian took the first set against Jelena Ostapenko but failed to build on that success as the Latvian ran out a 1-6 7-5 6-2 winner.

In the final match of the day, Anastasija Sevastova was beaten by Elena Rybakina, who had earned her place in the quarters by beating second seed Elina Svitolina the day before.

World number 61 Sevastova, who eliminated Coco Gauff, won the first set 6-2, but Rybakina fought back to claim the next two 7-6 (9-7) 7-6 (7-5).

Rainy conditions ensured there was no play at this week's other WTA event held in Bad Homburg, Germany, though one player was able to secure passage to the semi-finals.

Sara Sorribes Tormo claimed her place in the next round after Victoria Azarenka, her scheduled opponent, pulled out due to injury.

Petra Kvitova came from a set down to beat Katarzyna Piter on her return from injury at the Bad Homburg Open, while no play was possible in Eastbourne on Monday due to rain.

Kvitova withdrew from the French Open after suffering a freak ankle injury during her post-match media duties at Roland Garros.

The two-time Wimbledon champion recovered to get her grass-court season under way in Germany and battled to a 4-6 6-1 6-4 over Polish outsider Piter.

A week before the third grand slam of the year gets started at the All England Club, top seed Kvitova trailed 2-0 in the final set as she struggled with her serve, but broke three times to book a second-round meeting with Ann Li.

Sloane Stephens withdrew ahead of her scheduled match with Laura Siegemund due to a foot injury. Riya Bhatia stepped in with Stephens absent, but Siegemund consigned her to a 2-6 7-6 (7-1) 6-1 defeat.

Angelique Kerber needed only 50 minutes to see the back of Ekaterina Yashina 6-1 6-1 on home soil, grasping all five break-point opportunities.

Kerber will do battle with Anna Blinkova in round two and Jessie Pegula's next assignment is an encounter with Katerina Siniakova following a 6-1 6-2 defeat of Amandine Hesse.

Blinkova beat Clara Tauson 7-6 (7-4) 4-6 6-2, while Sara Sorribes Tormo saw off Martina Trevisan 6-4 3-6 6-2

Miserable weather in Eastbourne prevented Karolina Pliskova, Madison Keys, Bianca Andreescu and Madison Keys from playing at the Viking International.

Seeds Petra Martic and Coco Gauff were victorious at the Emilia-Romagna Open on Wednesday, but injury cut short Sara Sorribes Tormo's run in the tournament.

Gauff recorded five breaks of serve as she overcame Italian Camila Giorgi in routine fashion, a 6-2 6-3 triumph securing the third seed a place in the quarter-finals.

The American did have a few issues on her own serve, leading to seven double faults, but ended up winning in one hour and 11 minutes.

Martic, the second seed at the event, was made to work in the first set of her match against Ludmilla Samsonova, both players saving a break point on serve as it went the distance.

There was little to split the pair in the tie-breaker too, Martic edging it 7-5 as she capitalised on her first opportunity to take the set.

The second was more straightforward for the Croatian, an early beak of serve putting her in front before she repeated the trick to wrap up victory in the ninth game.

There were wins in straight sets for fellow seeds Caroline Garcia and Wang Qiang too, as they defeated Anna-Lena Friedsam and Martina Di Giuseppe respectively.

For Garcia, the triumph means a first quarter-final appearance in the 2021 season.

Sorribes Tormo was the only seeded player to exit in the day’s action, the Spaniard forced to retire at 2-2 in the deciding set against Sara Errani due to a problem with her left thigh.

"I'm very sorry for Sara. It was a battle, I know every time we play together it is like this. I was mentally ready to fight, to suffer," Errani said in her on-court interview.

Top seed Serena Williams is already out, beaten in straight sets by Katerina Siniakova to deal the 23-time grand slam champion a further blow ahead of this year's French Open.

Serena Williams had no problems in her opening match at the Emilia-Romagna Open, but sister Venus was unable to join her in the last 16.

Top seed Serena eased to a 6-3 6-2 triumph over teenage qualifier Lisa Pigato in the highlight of Monday's action in the clay-court tournament, wrapping up the result in 68 minutes.

Pigato, 17, was making her debut in the main draw of a professional event having come through qualifying in Parma.

She enjoyed early success against the legendary Williams, too, claiming a break of serve in the opening game, but the 23-time grand slam champion soon got to grips with the task at hand.

"The first game, she played really good and I needed to adjust to get back," Serena said afterwards. "It was a bit of both, figuring out her game as well."

Next up for the American, who accepted a wildcard into the event after an early exit at the Internazionali BNL d'Italia in Rome last week, will be Katerina Siniakova, a 6-1 6-3 winner over Clara Tauson.

Venus, however, failed to make it beyond her opening outing, losing out to Anna Karolina Schmiedlova despite taking the opening set.

The Slovakian made it four wins in five meetings against the seven-time major champion, eventually prevailing 5-7 6-2 6-2 after two hours and 39 minutes on court.

Elsewhere, Sloane Stephens defeated fellow American Caty McNally in two sets, while seventh seed Sara Sorribes Tormo overcame Bernarda Pera 6-4 6-2.

There was also a win in straight sets for eighth seed Caroline Garcia, who got the better of Paula Ormaechea in a contest that saw both players serve impressively.
