Lily Miyazaki’s US Open adventure was ended in the second round by Olympic champion Belinda Bencic.

The 27-year-old came through three matches to qualify at Flushing Meadows for the first time and then picked up a maiden grand slam win against Margarita Betova in round one.

But the world number 198 found 15th seed Bencic, of Switzerland, too tough a nut to crack as she bowed out 6-3 6-3.

Miyazaki still leaves New York with the consolation prize of having virtually doubled her earnings for the year with a £98,000 pay day for winning her first-round match.

A break early in the first set and two in the second set proved her undoing, although she did break the Bencic serve late on, prompting the 26-year-old to fling her racket to the ground.

But ultimately Bencic, a former semi-finalist, was too strong for the Tokyo-born debutant and broke again to seal the victory.

Miyazaki was supported once more by fellow Brit Jodie Burrage, who faces world number two Aryna Sabalenka in her second-round match on Thursday.

Burrage, who beat Anna Blinkova in straight sets on Tuesday night, said: “It’s a massive match. Probably one of the biggest ones I would have played in my career.

“But I’ll go out there and enjoy it like I always do. I’ll take the confidence from the matches I played this week and the last few weeks and months. Like everything, it’s lessons I’ve been learning from.”

Burrage feels her run here and to the second round at Wimbledon have earned her the respect of her peers in the locker room.

“I hope so. I hope that’s the reputation I’m getting,” she added.

“A few more of the girls, I start hitting with them, then you know them a little bit more. In the locker room, as well, it really is a place where you can chat to people and get to know people a little bit more.

“I’ve been speaking to Jessie Pegula a little bit because she’s in my bit of the locker room. Mostly we’re talking about the adidas outfit, what we’re wearing. Those little things start the conversations.

“But, yeah, hopefully they are building respect for me and finding who I am out as a player – hopefully not too soon because I think that surprise is helping me at the moment.”

British number one Katie Boulter has a big chance to move into the third round as she takes on Chinese world number 114 Wang Yafan.

World number five Ons Jabeur secured her first title of the season on Sunday with a 7-6 (8-6) 6-4 victory over Belinda Bencic in the Charleston Open final.

Jabeur, 28, enjoyed the best campaign of her career in 2022 as she reached the finals of Wimbledon and the US Open, but she was sidelined due to knee trouble following this year's Australian Open.

The Tunisian returned with early exits at both the Indian Wells Open and Miami Open, meaning she came into Charleston without consecutive wins since early January.

But she looked right back to her best at the WTA 500 event, not dropping a set the entire tournament.

After beating Lesia Tsurenko, Caroline Dolehide, Anna Kalinskaya and Daria Kasatkina to reach the final, Jabeur had to respond to early adversity against Bencic as the Swiss secured a break in the opening game of the first set.

Down 5-4 in the opener, Jabeur broke back at the last opportunity to keep the set alive, and after falling 6-4 behind in the tie-break she rattled off the next four points in a row to steal it.

The second set was all about making the most of her chances, as Jabeur only had three break-point chances compared to Bencic's five, but she was able to convert all three while Bencic could only snag two.

The final was a rematch from last year's Charleston Open title match, where Bencic prevailed over Jabeur in three sets, and it is Jabeur's first title since the German Open in June, where she again had to overcome Bencic in the final.

Jabeur now leads their head-to-head 3-2 in matches played at WTA Tour level.

Second seed Ons Jabeur secured a berth in a second successive Charleston Open final after triumphing 7-5 7-5 in a tight battle with third seed Daria Kasatkina.

Jabeur trailed a break in both sets but won in 109 minutes, aided by a three-hour rain delay at 5-3 down in the first frame allowing her to re-group.

The Tunisian had been a double break down at 4-1 in the first set, with Jabeur breaking Kasatkina when she served for the set at 5-2.

Jabeur's progress means she has reached her 11th WTA level final, this marking her first since the 2022 US Open which she lost to Iga Swiatek.

Jabeur lost last year's Charleston final to Belinda Bencic and the two may face off again in this year's decider, with the Swiss fourth seed leading top seed Jessica Pegula 7-5 6-6 (2-4) before rain forced their semi-final to be postponed until Sunday.

Bencic looked to have blown a 5-2 first-set lead, failing to serve out the opening frame before Pegula squared it up. But Bencic held serve, then broke Pegula to love to claim the lead.

There were breaks in the opening two games of the second set before it went to serve, until rain intervened with Pegula having a slight advantage in the tiebreaker.

Play will resume on Sunday not before 1:30pm local time, with the final scheduled for Sunday evening.

Second seed Tatjana Maria advanced to her second straight Copa Colsanitas final in Bogota, winning 6-3 6-4 over Briton Francesca Jones.

Maria will face either Peyton Stearns or Kamilla Rakhimova in Sunday's final.

The stage is set for a star-studded final weekend at the Charleston Open as top four seeds Jessica Pegula, Ons Jabeur, Daria Kasatkina and Belinda Bencic all advanced to the semi-finals on Friday.

It is the first time since the 2012 Stuttgart Open that all four top seeds reached the final four in a WTA 500 event.

Pegula, the top overall seed and the only remaining American, used her commanding serving game to overwhelm 12th seed Paula Badosa 6-3 7-6 (8-6).

She ended up winning 80 per cent of her accurate first serves – compared to 57 per cent for Badosa – and it resulted in the Spaniard producing just one break point opportunity in the match, which she could not take.

Pegula will meet fourth seed and Olympic gold medallist Belinda Bencic next after her relatively comfortable 6-3 6-3 triumph against Russia's Ekaterina Alexandrova.

Switzerland's Bencic needed just 80 minutes to get the job done, creating 12 break point chances compared to Alexandrova's two, while winning the first three games of each set.

After coming into the tournament without consecutive wins since early January, reigning Wimbledon and US Open finalist Ons Jabeur looked back to her best in a dominant 6-0 4-1 (retired) drubbing of Anna Kalinskaya.

Jabeur is yet to lose a set in Charleston, and she will try to keep that the case when she faces Daria Kasatkina in her semi-final.

Kasatkina earned her spot in the final four with Friday's only three-setter, emerging victorious 6-7 (5-7) 6-4 6-2 against Madison Keys in just over two and a half hours.

World number three Jessica Pegula was pushed all the way before emerging victorious 7-5 4-6 6-4 against Irina-Camelia Begu in Thursday's Charleston Open third round.

Pegula, the top-ranked American and the tournament's overall top seed, may have thought it was going to be smooth sailing after collecting a break-to-love in the match's opening game, but it was just the beginning of a two-hour-and-32-minute battle.

Begu played terrific tennis against a world-class opponent, winning 47 per cent of the match's total points, but she shot herself in the foot with eight double faults while Pegula had just one.

With the victory, Pegula booked her place in the quarter-final against Spain's Paula Badosa after her stylish 6-1 6-3 result over Russian 19-year-old Diana Shnaider.

Badosa now has a 4-2 record since the beginning of March, but both of those losses came to the in-form Elena Rybakina in eliminations from both the Indian Wells Open and the Miami Open.

Meanwhile, reigning Wimbledon and US Open finalist Ons Jabeur needed just 82 minutes to dispatch Caroline Dolehide 6-3 7-5, and combined with her opening victory against Lesia Tsurenko it is Jabeur's first consecutive wins since the Adelaide International in early January.

Jabeur will play Anna Kalinskaya in her quarter-final after the Russian upset two-time Australian Open champion Victoria Azarenka 6-4 7-6 (7-5).

It was a strong day for the Russians, as Ekaterina Alexandrova got the better of Julia Grabher 6-4 6-2, and world number eight Daria Kasatkina knocked out Bernarda Pera 6-3 7-6 (7-3).

Olympic gold medalist Belinda Bencic won the longest match of the day in a two-hour-and-45-minute war of attrition against Shelby Rogers 4-6 7-5 6-2, but the Americans had something to cheer for in the late window as Madison Keys advanced past Magda Linette 6-2 3-6 6-1.

Top seed Jessica Pegula cruised into the Charleston Open third round with a straight-sets victory over Anna Blinkova on Wednesday.

The American world number three triumphed 6-2 6-0 in 65 minutes, winning the second set to love in 27 minutes.

Blinkova, who is ranked 63rd in the world, was no match for Pegula, who won 71 per cent on first serve and 65 per cent on her second. Pegula also generated 10 break points, winning 71 per cent on the Russian's second serve.  

The American will take on Romanian 15th seed Irina-Camelia Begu in the round of 16, after she toppled resurgent 2020 Australian Open winner Sofia Kenin 6-1 6-4.

Defending champion and fourth seed Belinda Bencic triumphed in the evening session, breezing past Canada's Katherine Sebov 6-0 6-3 in 62 minutes.

Bencic will meet Shelby Rogers in the third round with the American edging countrywoman Caty McNally 6-7 (4-7) 7-5 6-1.

Ninth seed Madison Keys beat Hailey Baptiste 6-1 6-2, setting up a third-round clash with eighth seed Magda Linette who got past Varvara Gracheva 6-7 (3-7) 7-5 6-4.

Third seed Daria Kasatkina defeated Madison Brengle 6-2 6-1, progressing to face 38th ranked American Bernarda Para who beat Cristina Bucsa 6-3 6-4.

Spaniard Paula Badosa won 7-5 7-6 (8-6) over 2021 US Open runner-up Leylah Fernandez and will face Diana Shnaider who upset fifth seed Veronika Kudermetova 6-4 6-3.

Eugenie Bouchard's campaign at the Copa Colsanitas was halted in the second round with a 6-0 6-7 (7-9) 6-4 loss to fourth seed Kamilla Rakhimova.

Top 10 seeds Ons Jabeur, Caroline Garcia and Maria Sakkari were all eliminated in a day of upsets in the Miami Open second round on Friday.

Qualifier Varvara Gracheva earned her first career top-five win by beating 2022 Wimbledon and US Open finalist Jabeur 6-2 6-2 in only 67 minutes.

Fifth seed Caroline Garcia also crashed out, losing 6-2 6-3 to 74th-ranked Sorana Cirstea, having also recently beaten the Frenchwoman at Indian Wells.

Bianca Andreescu came from a set down to beat seventh seed Maria Sakkari 5-7 6-3 6-4 in a match that lasted over three hours.

Andreescu displayed some of the form that saw her lift the 2019 US Open title, fighting back from a set down and proving composed in the big moments.

The Canadian, who is ranked 31st, will take on 2020 Australian Open champion Sofia Kenin in the third round.

Second seed Aryna Sabalenka had few problems against Shelby Rogers, winning 6-4 6-3 in one hour and 17 minutes. Sabalenka will next face 31st seed Marie Bouzkova.

The 2023 Australian Open champion has won 65 main draw matches in WTA-1000 events, which equals Marion Bartoli and Ashleigh Barty at the 30th place since 2009 for the most wins at this level.

Indian Wells winner Elena Rybakina beat Anna Kalinskaya 7-5 4-6 6-3, and Petra Kvitova eased past compatriot Linda Noskova 6-3 6-0.

Ninth seed Belinda Bencic dropped just two games as she cruised past Leylah Fernandez 6-1 6-1, and will face Ekaterina Alexandrova next as the 18th seed needed three to get past Taylor Townsend.

Veronika Kudermetova was eliminated by Marketa Vondrousova 6-4 6-2, who goes up against Karolina Pliskova in round three after she eased past Wang Xinyu in straight sets.

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.

Iga Swiatek started the defence of her Qatar Open title by taking less than an hour to beat Danielle Collins on Wednesday.

Playing for the first time since she was knocked out of the Australian Open by Elena Rybakina in the fourth round last month, normal service was resumed by the domineering world number one in Doha.

The top seed brushed Collins aside in only 53 minutes, racing to a 6-0 6-1 victory to march into the third round.

Collins only won four points as she suffered the misery of a first-set bagel, an inspired Swiatek taking the opener in only 21 minutes.

Swiatek's run of games won was ended at nine when Collins got on the board at 3-1, but the Pole broke for a fifth time before serving it out for an emphatic victory.

The 21-year-old three-time grand slam champion, who made only six unforced errors, will do battle with Belinda Bencic for a place in the quarter-finals.

Bencic beat two-time champion Victoria Azarenka 1-6 7-6 (7-4) 6-4 to take her place in the last 16, storming back from 4-1 down in the second set when she appeared to be on her way out.

Second seed Jessica Pegula saved two match puts as she dug deep to beat Jelena Ostapenko 6-2 2-6 7-5 to set up a meeting with Beatriz Haddad Maia, who beat Daria Kasatkina in straight sets.

Fourth seed Coco Gauff got the better of Petra Kvitova 6-3 7-6 (8-6), while Veronika Kudermetova and Maria Sakkari also made it through.

Belinda Bencic continued her impressive run of form this season with a straight-sets win over Viktoriya Tomova in the opening round of the Qatar Open.

The seventh seed triumphed at the Abu Dhabi Open last week to add to her Adelaide International 2 success from January and is now seeking another title in Doha.

Bencic eased to a 6-0 6-1 win against Bulgarian qualifier Tomova and will face two-time tournament winner Victoria Azarenka for a place in the quarter-finals.

Maria Sakkari also advanced on Tuesday, overcoming Zheng Qinwen 6-2 3-6 6-3, as did fellow seeded player Daria Kasatkina with a 7-6 (7-5) 6-2 win against Rebecca Marino.

Zheng may have suffered an early exit, but last season's WTA Newcomer of the Year produced the shot of the tournament with a winning tweener en route to taking the second set.

Petra Kvitova, another two-time winner in Qatar, defeated Zhang Shuai 7-5 6-2, while Danielle Collins beat Elise Mertens 6-4 7-6 (8-6) and will now face top seed Iga Swiatek.

Second seed Jessica Pegula will take on Jelena Ostapenko, meanwhile, after the Latvian proved too strong for Madison Keys in a 7-5 6-2 victory.

Belinda Bencic claimed the inaugural Abu Dhabi Open title after saving three championship points in a gripping comeback win against Liudmila Samsonova.

Second seed Bencic did not drop a single set en route to Sunday's final, but she fell behind to Samsonova and was on the brink of defeat when 6-4 down in a second-set tie-break.

The Swiss dug deep to take the game to a decider, however, and she prevailed 1-6 7-6 (10-8) 6-4 in a time of two hours and 48 minutes to win the eighth WTA title of her career.

World number nine Bencic, who was also victorious at the Adelaide International 2 in January, made a slow start against an opponent she had failed to beat in three meetings.

Samsonova broke Bencic in the second and sixth games of the opening set in a dominant start as she looked to make it 5-0 in championship matches on the WTA Tour.

Bencic improved in the second set, although a break of serve apiece meant it went the distance.

Eighth seed Samsonova looked good value to wrap up a straight-sets win when 6-4 up, only for Bencic to save both championship points, and likewise at 8-7.

Three points in a row saw the 25-year-old take the tie and level up the contest, which she went on to win with a couple of breaks in the deciding set.

Belinda Bencic breezed through to the Abu Dhabi Open final after a commanding 6-2 6-3 victory over Beatriz Haddad Maia on Saturday.

The world number nine, who is yet to drop a set this week, is into her second WTA final of 2023, having triumphed in Adelaide last month.

Haddad Maia arrived in the clash fresh from winning each of her previous six encounters with top-10 opponents, including her quarter-final victory over Wimbledon champion and Australian Open finalist Elena Rybakina.

But the Brazilian had already spent almost eight hours on court in this event prior to this contest, in which Bencic dropped just five games on the way to wracking up her 11th win of the campaign – the joint-most on the WTA Tour alongside Melbourne winner Aryna Sabalenka.

She will play number eight seed Liudmila Samsonova in Sunday's final after the Russian defeated Zheng Qinwen 6-4 1-6 6-4.

After being edged out in the first set, Zheng responded to motor through the second and seemed to have the momentum going into the third, but Samsonova showed impressive resolve to see off three break points against her, before taking her first on match point.

At the Linz Open, top seed Maria Sakkari is out after going down 3-6 6-3 6-4 to sixth seed Petra Martic in a match that lasted over two and a half hours.

The Croatian will play Anastasia Potapova in the final after the number eight seed claimed yet another three-set victory this week to see off Marketa Vondrousova 6-1 6-7 (4-7) 6-3 and secure her fifth WTA final appearance.

Top seed Daria Kasatkina succumbed to a surprise quarter-final exit against Zheng Qinwen at the Abu Dhabi Open as Belinda Bencic marched into the final four.

Kasatkina was blown away in just 78 minutes by Zheng, who only dropped three games in her 6-1 6-2 upset of the world number eight.

Zheng, who defeated world number 12 Jelena Ostapenko on Wednesday, executed her serve-and-volley approach expertly throughout, with the 20-year-old claiming the third top-10 victory of her career to reach her third tour-level semi-final.

Another Russian player stands between Zheng and a place in the final after eighth seed Liudmila Samsonova dispatched compatriot Veronika Kudermetova 6-3 6-3.

Bencic found form after edging a tough first set against qualifier Shelby Rodgers, who saw her run ended by a 7-6 (7-5) 6-2 defeat.

Second seed Bencic will face Beatriz Haddad Maia in the semi-finals after the Brazilian railed to beat Elena Rybakina 3-6 6-3 6-2 less than 24 hours after beating Yulia Putintseva in a marathon three-hour encounter.

Meanwhile, top seed Maria Sakkari secured her progress to the last four at the Linz Open with a 6-3 7-6 (10-8) straight sets win over Donna Vekic.

The Greek will face off with Petra Martic next, while Anastasia Potapova faces the unseeded Marketa Vondrousova in the other semi-final.

Belinda Bencic stood firm to reach the quarter-finals of the Abu Dhabi Open while fellow favourites Anett Kontaveit and Jelena Ostapenko headed home.

Bencic clinched her second last-eight spot of the year with a 6-4 7-5 win over Marta Kostyuk, though the world number nine was pushed hard by the Ukrainian, who remains without a top-10 win in her career after failing to see through the second set from 5-3 up.

The second seed will next face Shelby Rogers, who advanced courtesy of a walkover following Kontaveit's retirement through injury after falling 4-1 behind in the pair's decisive third set. 

Kontaveit was not the only seed to fall, with Ostapenko slipping to a surprise 7-6 (12-10) 6-1 loss against China's Zheng Qinwen.

Fourth seed Veronika Kudermetova fared better, however, racing to a 6-1 7-5 win against Elise Mertens to keep her campaign alive. 

At the Linz Open, top seed Maria Sakkari cruised to a straight-sets success against Varvara Gracheva, while Anastasia Potapova battled to a 7-5 3-6 6-3 victory against Jule Niemeier.

Third seed Irina-Camelia Begu was the highest-ranked player to exit in the last 16 in Austria, suffering a 6-2 6-1 defeat against Danish 20-year-old Clara Tauson.

Aryna Sabalenka is hoping she can move to another level in a "new beginning" this year after beating Belinda Bencic to reach a first Australian Open quarter-final.

The fifth seed from Belarus saw off Bencic 7-5 6-2 on Rod Laver Arena on Monday and will face Donna Vekic in the last eight.

Sabalenka has not dropped a set in her four matches in the first grand slam of the year at Melbourne Park and has been installed as the favourite to take the title after Iga Swiatek's exit.

The 24-year-old played in a second successive US Open semi-final last year but has never made it is far as a championship match at a major.

Sabalenka won the Adelaide International 1 before heading to Melbourne and is optimistic she can kick on in 2023.

She said: "I want to believe that the way I'm working right now, the way I'm on the court right now, this is the new beginning, and this is the next step. So I really want to believe that it's going to really help me."

Sabalenka has endured struggles with her serve, but appears to have put that behind her after addressing the issue.

She added: "I worked a lot on my serve. I was keep trying, keep believing, keep changing. Then I worked on my, like, biomechanics.

"Basically that's it. But I was doing everything. I thought it's mentally, but it wasn't. We changed a lot of things on how we work on my serve. We tried to work more, less. We tried so many different things.

"In the end of the season when I start working with the biomechanics guy, he helped me a lot. I think from there, everything started to kind of get on that level."

Croatian Vekic ended 17-year-old Czech Linda Fruhvirtova's impressive run with a 6-2 1-6 6-3 victory.
