Number four seed Shuai Zhang made it through to the quarter-finals of the Nottingham Open after a straight-sets win over home hope Jodie Burrage.

Zhang was never in danger against her unseeded opponent, easing to a 6-2 7-6 (7-4) win to set up a last-eight clash with Tereza Martincova.

Martincova brushed aside number eight seed Magda Linette 6-2 7-6 (7-3) in their round-of-16 meeting on Wednesday.

Elsewhere, Viktorija Golubic beat Heather Watson 7-5 6-2, while the match between number three seed Camila Giorgi and Harriet Dart was suspended at the start of the third set after the Briton had made it one set each. 

Meanwhile, rain caused havoc at the Rosmalen Grass Court Championships, with top seed Aryna Sabalenka's match against Arianne Hartono the only one to partially take place.

The match was called off for the day after Sabalenka had claimed the first set 6-2.

Emma Raducanu has "no idea" if she will be fit for Wimbledon after retiring from her first-round match against Viktorija Golubic at the Nottingham Open on Tuesday. 

Second seed Raducanu conceded the match after 36 minutes having sustained an injury to her left side while down a break at 4-3 in the opening set. 

The 19-year-old is scheduled to appear at Birmingham next week before heading to Wimbledon, where she reached the fourth round last year. 

US Open champion Raducanu, who made her WTA Tour debut in Nottingham last year, is unsure if she will recover in time to feature at the All England Club. 

"I think I pulled something, I am not really sure what exactly happened," Raducanu said. 

"I have just come off court, an absolute freak injury. I don't know what I could have done more about it. That is it. 

"I have no idea [about Wimbledon]. It could have just seized up and gone into spasm and then it is really bad for a few days. I have no idea. I cannot diagnose myself. I will get it checked out." 

Raducanu was the only seed to exit the tournament, with top seed Maria Sakkari overcoming Camila Osorio 6-2 6-3 to advance to a second-round meeting with Rebecca Marino. 

Beatriz Haddad Maia came from a set down to beat Wang Qiang 5-7 6-4 6-3, while Ajla Tomljanovic and Camila Giorgi had comfortable victories against Wang Xinyu and Sonay Kartal respectively. 

Aryna Sabalenka cruised into the second round of the Rosmalen Grass Court Championships by defeating Kateryna Baindl 6-4 6-1. 

Fifth seed Liudmila Samsonova, meanwhile, succumbed to a 6-3 6-4 loss to Ann Li in an hour and 22 minutes. 

There would have been further casualties among the seeds had Tamara Zidansek, Ekaterina Alexandrova and Elise Mertens not fought from a set down to win their opening matches. 

Tereza Martincova got off to a winning start at the Nottingham Open, where there were three British winners on home soil on Monday.

World number 60 Martincova recorded a 7-6 (7-1) 7-5 triumph over France's Oceane Dodin to ease into the second round in Nottingham.

Heather Watson, ranked 102nd in the world, had no problems as she eased past Katie Volynets 6-4 6-2, and fellow Briton Hannah Dart followed suit by defeating Donna Vekic 6-4 6-3.

Jodie Burrage completed the first-round sweep for British women, downing Lin Zhu 7-6 (7-5) 6-4.

At the Rosmalen Grass Court Championship, top seed Aryna Sabalenka was due to face Kateryna Baindl but bad weather curtailed the day's play early.

Earlier on, Anna Kalinskaya edged out Suzan Lamens 7-6 (7-5) 6-3 in the first round, while Catherine McNally, Storm Sanders, Olivia Gadecki and Jamie Loeb were all triumphant in qualifying.

Novak Djokovic returns to the grand slam arena, Carlos Alcaraz is threatening to follow in the footsteps of Rafael Nadal, and Iga Swiatek is suddenly unstoppable.

The French Open is rich in promise as the Roland Garros clay courts are swept in anticipation of the greats of tennis stepping out to begin their campaigns.

It has been the women's draw that has looked the most wide open in recent seasons, yet this year it is hard to look beyond Swiatek; however, the men's title battle promises to provide a sensational battle.

Here, Stats Perform assesses the contenders for the two main trophies: the Coupe des Mousquetaires and the Coupe Suzanne Lenglen.

KID INTERRUPTS G.O.A.T. RACE

Nadal took full advantage of Djokovic and Roger Federer being absent from the Australian Open, carrying off his 21st grand slam title to go top of the men's all-time list, one ahead of those two great rivals.

Federer is again missing, rehabbing after knee surgery, and the likelihood is he has played his final major already, but Djokovic is emphatically back. His confidence is surging once more, having taken a knock amid the drama of his deportation from Australia in January and being frozen out of the Indian Wells and Miami events due to the United States' COVID-19 rules.

A semi-final run in Madrid, where he lost a three-set monster to Alcaraz, was followed by Djokovic carrying off the Rome title for a sixth time when he saw off Stefanos Tsitsipas in the final.

Djokovic turns 35 on Sunday, as main-draw action gets under way in Paris, but he is the defending champion and firmly believes he can succeed again.

Assessing his prospects for Paris, Djokovic said after his Rome triumph: "With rankings and the way I've been playing in the last few weeks, I would rate myself as one of the favourites. I don't obviously spend too much time thinking who's going to win it or who might have the best chance. I always think about myself.

"I go there with the highest ambitions. I really like my chances. Best-of-five, you play every second day. It's a grand slam. It's different. Really, the grand slams are played different. You have to approach it differently. But the way I've been feeling on the court and off the court in the last few weeks, I really think I can go far."

The chief threat to Djokovic could come not from 'King of Clay' Nadal, but from the 13-time champion's fellow Spaniard, 19-year-old Alcaraz.

Bidding to become the first teenage winner of the men's title since Nadal, also 19, triumphed for the first time in 2005, Alcaraz arrives in Paris with four titles already secured this year, including three on clay in Rio, Barcelona and Madrid. The other title came on hardcourt at the Masters 1000 event in Miami, and Alcaraz has rocketed from 32nd at the start of the year to number six in the world rankings.

Many expect his grand slam haul to reach double digits, just like the Big Three he has grown up watching and learning from. The first slam must come somewhere, and it might well come in Paris in a fortnight's time.

Don't discount Nadal, but his form has been a shade unconvincing since coming back from a rib injury, while Tsitsipas looks the next most likely after winning on clay in Monte Carlo and finishing runner-up to Djokovic in Rome. The Greek has unfinished business in Paris, after the heartache of losing last year's final from two sets up.

IGA TO PLEASE? POLE GOES FROM SHOCK WINNER TO FIRM FAVOURITE

The first thing to point out is that the French Open women's singles title has been won by eight different players in the last eight years.

Iga Swiatek was a surprise champion in 2020, at the tournament that was delayed until the Paris autumn due to the pandemic. She was ousted by Maria Sakkari in the quarter-finals last year but returns on a roll, having won an incredible five consecutive tournaments.

The 20-year-old has won 38 of the last 39 sets she has contested, the odd one out going against her on a tie-break, and her winning streak has reached 28 matches. Since Ash Barty retired, nobody has been able to lay much of a glove on Swiatek.

If she wins the French Open, that run will reach 35 matches, equalling the longest run in the 2000s, previously achieved by Venus Williams during a glory run that saw her win events including Wimbledon, the Olympic Games and US Open in the year 2000.

Tunisia's Ons Jabeur has been spoken of as a possible challenger to Swiatek, but she was swatted away 6-2 6-2 by the youngster in the Rome final last weekend.

So who challenges the favourite? Even those who have been there and done that struggle to look beyond Swiatek. According to Martina Navratilova: "You can’t be any hotter than she is right now."

Navratilova told the WTA website: "She looks pretty unbeatable on any surface, particularly the clay now."

The last player to beat Swiatek was Jelena Ostapenko, in Dubai. Ostapenko, a surprise 2017 French Open champion, had a sizzling spell of form in February but has gone off the boil since. It might take someone of her hard-hitting nature to knock Swiatek out of her stride, though, so if Ostapenko can navigate the early rounds she becomes a real contender. The Latvian's career record against Swiatek? An impressive 3-0.

Who else? Simona Halep's coaching tie-up with Patrick Mouratoglou – Serena Williams' former coach of long-standing – has raised eyebrows and now it might be time for it to raise her results level too. Halep has won in Paris before, in 2018, so don't count her out.

Aryna Sabalenka, Sakkari, Paula Badosa. Such players come into the mix if Swiatek slips up, but there has been scant sign of that happening.

Iga Swiatek continued her remarkable winning run to reach the Internazionali d'Italia final as she defeated Aryna Sabalenka 6-2 6-1.

Top seed Swiatek extended to 26 matches unbeaten, dating back to mid-February, with victory over Bianca Andreescu to set up the last-four meeting with Sabalenka, who battled past Amanda Anisimova.

The pair exchanged opening breaks in a tentative start to the clash in the Italian capital before Sabalenka again failed to hold her serve as Pole Swiatek took an early 3-1 lead.

World number eight Sabalenka, the third seed in the tournament, offered little response as the in-form Swiatek then claimed the first set with ease.

Sabalenka was again caught cold and had no answer as world number one Swiatek raced out the blocks in the second set, breaking twice via marathon rallies, to gain a 4-0 lead.

Swiatek swiftly wrapped victory up, despite a short medical time out for her opponent, and has now won all three of her WTA Tour encounters with Sabalenka in 2022, conceding just 12 games in the process.

Meanwhile, in the last 25 years only Serena Williams in 2013, Kim Clijsters in 2003 and Martina Hingis in 1998 have reached the final in Rome with fewer games dropped than Iga Swiatek this season (17).

The 20-year-old Swiatek continues on her quest for a fourth straight WTA 1000 crown and fifth consecutive title and in the final will face either Ons Jabeur or Daria Kasatkina, who face off later on Saturday.

Iga Swiatek's superb form continued as she overcame another grand slam champion in the form of Bianca Andreescu to reach the last four of the Internazionali d'Italia.

Swiatek, who will be aiming to regain the French Open title she won in 2020 when she heads to Roland Garros later this month, has won 26 matches on the bounce after a 7-6 (7-2) 6-0 triumph over Andreescu, the 2019 US Open champion.

The 20-year-old Pole has now won all nine of her matches since she became world number one following Ash Barty's retirement in March. 

That makes her part of an exclusive club, with only Justine Henin (in 2004) and Victoria Azarenka (in 2012) having achieved that feat in the 21st century.

Swiatek's winning streak also matches Azarenka's 2012 sequence as the fifth-longest this century. Henin and the two Williams sisters are the only players to have won more consecutive matches since the start of 2000.

"Being in that kind of group is like a dream come true for me," said Swiatek, who has won 38 of her past 39 sets since her fourth-round match at the Indian Wells Open.

"I wouldn't think of that when I was younger. I'm pretty happy that I could do that because consistency was the thing I really wanted to work on last year. This year I feel like it clicked."

The only player to have beaten Swiatek in a tour-level quarter-final to date is Maria Sakkari, at Roland Garros last year, but the Greek saw victory slip from her grasp against Ons Jabeur.

Sakkari led 6-1 5-2 against the Tunisian, yet Jabeur rallied remarkably to claim a first career win against a top-five opponent on clay, prevailing 1-6 7-5 6-1.

After winning the Madrid Open last week, Jabeur has now won 10 straight matches, while she has claimed 16 victories on clay in 2022, leading the way on the WTA Tour.

While Jabeur will face world number 23 Daria Kasatkina, whose opponent Jil Teichmann retired when 6-4 3-2 down, Swiatek will go up against third seed Aryna Sabalenka.

Amanda Anisimova had not lost to Sabalenka in four previous meetings over the past three years, but her luck ran out as she went down 4-6 6-3 6-2.

World number one Iga Swiatek beat Victoria Azarenka 6-4 6-1 to progress to the quarter-finals of the Internazionali d'Italia in Rome on Thursday. 

Swiatek, who became the first female player to win 25 consecutive matches since Serena Williams in 2015, will face Bianca Andreescu in the last eight after she eased past Petra Martic 6-4 6-4.

"I didn't start well, and everybody could see that," Swiatek told reporters. "I'm really happy with the way I reacted and how I improved in the first set.

"Also how different the second set looked to the first one because I could really reset and really change the way I played. That's the most positive thing for me."

There was a shock in the final game of the day, though, as Daria Kasatkina dumped out number two seed Paula Badosa 6-4 6-4. 

Third seed Aryna Sabalenka sealed a third straight win over Jessica Pegula, easing to a 6-1 6-4 victory, while fourth seed Maria Sakkari defeated Coco Gauff 6-4 7-5.

Seventh seed Danielle Collins was knocked out by unseeded compatriot Amanda Anisimova, the 20-year-old cruising past the Australian Open finalist 6-2 6-2.

There were also victories for Jil Teichmann, who overcame Elena Rybakina 6-7 (3-7) 6-3 7-5, and ninth seed Ons Jabeur, who beat Yulia Putintseva 6-3 6-2.

Iga Swiatek and Paula Badosa progressed to the third round of the Internazionali d'Italia with ease as the former continued her impressive winning run on Wednesday.

Top seed Switaek, seeking a fifth consecutive title, breezed past Elena-Gabriela Ruse 6-3 6-0 as she became the first female player to win 24 consecutive matches since Serena Williams in 2015.

Badosa followed suit by dispatching Aliaksandra Sasnovich 6-2 6-1 in just an hour and 17 minutes, teeing up a third-round clash with Daria Kasatkina, who beat Leylah Fernandez 4-6 6-3 7-6 (7-2).

Aryna Sabalenka, the third favourite in Italy, also made light work of Zhang Shuai to triumph 6-2 6-0, while fourth seed Maria Sakkari cruised past Madrid Open semi-finalist Ekaterina Alexandrova 6-3 6-2.

Sakkari will next face a Rome rematch with Coco Gauff, who defeated compatriot Madison Brengle 6-2 6-4. Teenager Gauff's sole win against Sakkari came at this tournament in the second round last year.

Yulia Putintseva came from behind to beat Garbine Muguruza 3-7 7-6 (7-4) 6-1, and will next meet Ons Jabeur, who made it eight successive main-draw wins by defeating Ajla Tomljanovic 7-5 6-2.

Seventh seed Danielle Collins also battled past former world number one Simona Halep 7-6 (7-1) 6-3.

There was no such joy for fifth seed Anett Kontaveit as she crashed out to Petra Martic in straight sets, while Jil Teichmann upset former Rome champion Karolina Pliskova in a three-set thriller.

Belinda Bencic, who was ranked as 12th seed, was another early casualty as she fell to a 7-6 (7-4) 6-1 defeat against American Amanda Anisimova.

Meanwhile, Jessica Pegula secured her third-round spot after Anhelina Kalinina withdrew due to injury, with Victoria Azarenka earning a straightforward 6-2 6-4 victory over Camila Osorio to get a shot at favourite Swiatek in the next round.

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.

World number one Iga Swiatek maintained her impressive form by seeing off Aryna Sabalenka in straight sets in Sunday's Stuttgart Open final to win a fourth straight WTA title.

Swiatek was made to work hard in Saturday's semi-final against Liudmila Samsonova as she dropped a rare set, but she was back to her imperious best against Sabalenka.

The 20-year-old prevailed 6-2 6-2 in 84 minutes to make it 23 victories in a row – only five other different players have enjoyed longer winning runs since 2000.

With her latest triumph in Germany, Swiatek has now won 30 WTA matches in 2022, compared to 36 in the whole of 2021.

She has won the Qatar Ladies Open, Indian Wells and Miami Open in straight succession, having also reached the semi-finals of the Australian Open in January.

Sabalenka, who eliminated Paula Badosa, Anett Kontaveit and Bianca Andreescu en route to the final, was the latest player to fall short in trying to stop the sublime Swiatek.

After saving a break point in the opening game, Swiatek held serve and broke her opponent in the next game before comfortably seeing out the first set.

The Pole never looked under serious threat in the second set as she took the last four games to down world number four Sabalenka, who lost to Ash Barty in this final last year.

At the Istanbul Cup, meanwhile, Anastasia Potapova beat Veronika Kudermetova 6-3 6-1 to clinch her maiden career title.

Qualifier Potapova recovered from a set down to beat Yulia Putintseva in Saturday's semi-final and was too strong for Kudermetova in what was her third career final.

Kudermetova broke Potapova early on and led 3-1 in the opening set, but the latter soon found her range and took advantage of some sloppy mistakes from her opponent.

After battling to victory in the first set, Potapova looked far more comfortable in the second as she produced a number of impressive shots en route to a breakthrough triumph.

Iga Swiatek had to come from a set down to book her place in the Stuttgart Open final with a hard-earned victory over Liudmila Samsonova.

The world number one produced a 22nd consecutive victory as she scraped a 6-7 (4-7) 6-4 7-5 win in a contest that lasted more than three hours.

The Pole will face third seed Aryna Sabalenka in Sunday's final on the German clay.

Swiatek broke early to race out to a 3-0 lead, but was pegged back by her Russian opponent, who fought hard to claim the first set on a tie-break.

The 20-year-old was looking to break the record of Serena Williams, equalling a feat of winning 28 sets in a row, but Samsonova prevented her from doing so.

It was the first time Swiatek had dropped a set since her Indian Wells Open last 16 match against Angelique Kerber in March, but she soon got back into her rhythm and clinched the second set 6-4.

She broke early again in the decider, but was once more broken back by a determined Samsonova, and Swiatek showed frustration with herself as she struggled to put away her opponent.

However, an unusually sloppy service game from Samsonova gave Swiatek another break in the 11th game of the set, which she closed out to seal her place in the final.

The other semi-final in Stuttgart saw Sabalenka overcome second seed Paula Badosa 7-6 (7-5) 6-4.

There were 14 double faults (seven each) in the match, but it was Sabalenka's big serve that ultimately led her to victory, hitting nine aces and winning 76.9 per cent of points on her first serve.

The Belarusian also saved six of eight break points faced as she ultimately eased past her Spanish opponent.

At the Istanbul Cup, third seed Veronika Kudermetova will play Anastasia Potapova in the final after seeing off second seed Sorana Cirstea in straight sets, 6-3 6-3.

Potapova had earlier come from a set down to beat Yulia Putintseva 2-6 6-2 6-2 in the other semi-final.

Iga Swiatek believes a hard-won victory over Emma Raducanu on Friday will steel her for challenges ahead after reaching the Stuttgart Open semi-finals.

World number one Swiatek landed a 21st consecutive victory as she edged out US Open winner Raducanu 6-4 6-4 in an hour and 45 minutes on the German clay.

There was plenty to admire from both players, but in the end it was another straight-sets success for Swiatek, who dropped only two games in her previous round against German Eva Lys.

It makes the 20-year-old Pole the first woman to win 28 consecutive sets on tour since Serena Williams, who did so from the 2012 US Open to the 2013 Australian Open.

Swiatek broke early in the first set to take charge, and with 19-year-old Raducanu battling a back problem the rankings leader soon got ahead in the second too.

This was Raducanu's first-ever match against a player ranked inside the WTA top 10, a peculiar statistic given she is already a grand slam champion.

Swiatek, like her opponent, knows how it feels to win a grand slam as a teenage surprise package, having triumphed as a 19-year-old at the 2020 French Open when ranked only 54th in the world.

At 4-3 in the second set of this contest, Swiatek saved two break points with clinical forehand winners out of the reach of Raducanu, shouting out in satisfaction moments later as she held serve to move a game away.

Raducanu had two more break chances in Swiatek's next service game but again could not convert as her opponent sealed victory.

Swiatek said: "I'm pretty happy that today's match was longer. Not for now, but for the future it's going to give me a lot of experience.

"Right now I want to play really aggressively, and I think this game style is going to fit the surface, and it fit the hardcourts as well."

She will face unseeded Liudmila Samsonova next after the Russian, playing as a neutral, beat Laura Siegemund 7-5 6-3.

The other semi-final in Stuttgart will see second seed Paula Badosa take on third seed Aryna Sabalenka.

Badosa was a 7-6 (11-9) 1-6 6-3 winner against Ons Jabeur, while Sabalenka fended off Anett Kontaveit 6-4 3-6 6-1.

At the Istanbul Cup, Friday saw quarter-final wins for Veronika Kudermetova and Anastasia Potapova, along with Sorana Cirstea and Yulia Putintseva.

Those results set up a semi-final on Saturday between second seed Cirstea and third seed Kudermetova, with Putintseva and Potapova also facing off.

Daniil Medvedev headlines the list of Russian and Belarusian players who will be banned from competing at Wimbledon this year.

In the wake of Russia's invasion of Ukraine, which was facilitated by Belarus, the four grand slams and the ATP and WTA Tours initially confirmed Russian and Belarusian players would be able to continue playing, albeit under neutral flags.

However, the All England Club has now decided athletes from the two nations will be unable to feature at the season's third grand slam.

That means reigning US Open champion Medvedev, ranked second in the world by the ATP behind Novak Djokovic, will not be involved.

With Medvedev a doubt for the French Open having undergone hernia surgery, he could miss two of this year's majors. He has never had much success at Wimbledon, with his best run ending in the fourth round in 2021.

WTA world number four Aryna Sabalenka, who hails from Belarus, is another big name to miss out, along with Russian ATP world number eight Andrey Rublev, who has won two titles so far in 2022.

Russian women's number one Anastasia Pavlyuchenkova, compatriot and 2018 Wimbledon quarter-finalist Daria Kasatkina and Belarusian two-time All England Club semi-finalist Victoria Azarenka will all also be absent.

"We share in the universal condemnation of Russia's illegal actions and have carefully considered the situation in the context of our duties to the players, to our community and to the broader UK public as a British sporting institution," a statement on the official Wimbledon website read.

"We have also taken into account guidance set out by the UK Government specifically in relation to sporting bodies and events.

"In the circumstances of such unjustified and unprecedented military aggression, it would be unacceptable for the Russian regime to derive any benefits from the involvement of Russian or Belarusian players with The Championships. It is therefore our intention, with deep regret, to decline entries from Russian and Belarusian players to The Championships 2022."

Chairman of the All England Club, Ian Hewitt, said: "We recognise that this is hard on the individuals affected, and it is with sadness that they will suffer for the actions of the leaders of the Russian regime.

"We have very carefully considered the alternative measures that might be taken within the UK Government guidance but, given the high profile environment of The Championships, the importance of not allowing sport to be used to promote the Russian regime and our broader concerns for public and player (including family) safety, we do not believe it is viable to proceed on any other basis at The Championships."

Wimbledon's statement confirmed that the ban would be "reconsidered" should circumstances change by June.

The move comes a month after UK sports minister Nigel Huddleston warned Medvedev and other Russian athletes they might be banned from Wimbledon unless they denounced president Vladimir Putin.

Medvedev and Rublev both called for peace in the immediate aftermath of Russia's attack on Ukraine.

World number five and the tournament's top seed, Aryna Sabalenka, was upset by American Amanda Anisimova 3-6 6-4 6-3 in the third round at the Charleston Open.

Sabalenka's serve was the key to her early success, connecting on 73 per cent of her first serves, and winning 15 of the 19 points in that situation (79 per cent).

When Sabalenka's first serve percentage fell to 48 in the second set, Anisimova found her footing, breaking twice in the frame, before pouncing on the Belarusian's lacklustre second serve in the deciding set, winning seven of nine opportunities to earn the break and the win.

Sixth seed Jessica Pegula was also bounced in surprising fashion, losing 6-4 3-6 6-4 to unseeded compatriot Coco Vandeweghe.

In a razor-close contest, it came down to who took their chances, as Vandeweghe saved seven of the 10 break points she faced, while Pegula could only save one of five.

World number 10 Ons Jabeur had no problem navigating the challenge of Emma Navarro, winning 6-3 6-2 as she broke her opponent's serve on six occasions.

Canadian seventh seed Leylah Hernandez also fell victim to an unseeded upset, going down 3-6 6-3 6-4 against Poland's Magda Linette.

In a meeting between two top-10 seeds, Belinda Bencic got the better of Madison Keys to edge it 6-4 6-4.

Second seed Paula Badosa had to come from a set down to eventually get the better of Claire Liu 3-6 7-6 (10-8) 6-1.

In the late session, French 12th seed Alize Cornet went down in a close tussle against Ukraine's Anhelina Kalinina 7-6 (7-5) 7-5, while Jabeur won her second match of the day, beating Irina Begu 6-3 6-2.

Meanwhile, in Bogota at the Copa Colsanitas, top seed Camila Osorio dispatched Turkish opponent Ipek Oz 6-3 7-6 (7-4) to move on to the quarter-final where she will meet Elina Avanesyan.

Top-seeded Aryna Sabalenka won for the first time since late February, defeating Alison Riske 7-6 (7-3) 6-4 at the Charleston Open on Wednesday.

Losing her opening matches at the sunshine double of Miami and Indian Wells, after only taking five games off Iga Swiatek at the quarter-final in Doha, the world number five improved her head-to-head record with Riske to 5-0.

Sabalenka by no means cruised to victory, though, failing to close the match out at 5-2 in the second set. Riske had four break points to level at 5-5, but the 23-year-old powered through when she needed to, eventually closing out after an hour and 49 minutes.

Second-seeded Paula Badosa of Spain and ninth-seeded American Madison Keys also advanced to the third round at Charleston, with respective wins over Anna Bondar and Ulrikke Eikeri.

Badosa, who made the semi-finals in Charleston last year, overcame a mid-match rain delay to eventually win in an hour and 35 minutes.

Jessica Pegula continued her positive run of form after making the semi-finals in Miami, accounting for Jasmine Paolini with a 6-2 6-1 victory.

Other seeded winners included Belinda Bencic and Alize Cornet, while Elina Rybakina, Ajla Tomljanovic and Shuai Zhang were among seeds who lost on Wednesday.

The weather in South Carolina continued to be a problem at the first WTA clay-court event this season, however, as the match between Ons Jabeur and Emma Navarro was suspended due to heavy rain.

Meanwhile at the Copa Colsanitas in Bogota, Rebecca Peterson was the only seeded player in action on Wednesday, and lost 6-1 6-4 to Germany's Tatjana Maria.
