Paula Badosa had to awkwardly inform a reporter she had lost her second-round match after a back injury ended her Wimbledon campaign.

The Spaniard was forced to retire when trailing 6-2 1-0 to Marta Kostyuk after her troublesome stress fracture flared up and she revealed she will not be able to play the mixed doubles with her boyfriend Stefanos Tsitsipas.

To add insult to injury, news of her fitness struggles on Court 18 had clearly not reached an international reporter, who opened her post-match press conference by congratulating her on her victory, prompting a toe-curling exchange.

Responding to the opening comment, Badosa simply replied: “I lost.”

The reporter did not acknowledge her answer and asked her to talk about her fitness and confidence level, to which she replied: “For your information, I just lost. I didn’t win. So, yeah.”

The moderator then again informed the journalist Badosa had lost, which was received by surprise.

Once the result had been established in the room, Badosa went on to say that she will be withdrawing from the mixed doubles due to the problem, robbing fans of a on-court love story.

Asked whether she would be able to compete: “No, no, I won’t be able. The injury is the same as I have been struggling the past weeks.

“It’s the stress fracture. I tried my best to try to play here, but yesterday when I woke up I already, after my first-round match, felt it again. It’s a little bit worse.

“So I will need a few days off and talk to my team and see what I do in the next days and the next weeks.

“The first match I was pretty happy because I felt OK. After the match I spoke with my team, and I was, like, it wasn’t very bad.

“But yesterday, as I said when I woke up, I was worse. Today was worse. I wanted to give it a try in the match, but I think the smartest thing was to stop.”

Kostyuk will play 25th seed Maddison Keys after the American beat Viktorija Golubic 7-5 6-3 while two-time champion Petra Kvitova beat Aliaksandra Sasnovich 6-2 6-2 to reach the third round.

Sixth seed Coco Gauff slumped to a third-round exit at the hands Paula Badosa at the Madrid Open on Saturday, while Mirra Andreeva celebrated her 16th birthday by setting up a meeting with Aryna Sabalenka.

Badosa – the highest-ranked Spanish player in the women's draw – needed just 71 minutes to wrap up a 6-3 6-0 win over last year's Roland Garros runner-up, thrilling a supportive home crowd at the Manolo Santana Stadium.

Badosa edged a competitive start on the clay, with each of the first five games featuring break points, before the 25-year-old forced a series of errors from Gauff to take the opener.

The second set was far more straightforward, the error-prone Gauff rounding out the match by losing eight consecutive games to miss out on a spot in the last 16.

Gauff was not the only seed to be humbled on Saturday, with Caroline Garcia falling to a 7-6 (7-2) 6-3 loss in her meeting with Egypt's Mayar Sherif.

Sabalenka – the highest-ranked player in action on Saturday – enjoyed a more productive outing, however. 

She saw off a spirited challenge from Colombia's Camila Osorio to clinch a 6-4 7-5 victory, teeing up a last-16 meeting with surprise package Andreeva. 

Playing on her 16th birthday, wildcard Andreeva celebrated in style with a 6-3 6-3 win over Poland's Magda Linette, continuing a dream run which has also seen the Russian eliminate Leylah Fernandez and Beatriz Haddad Maia.

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.

It was a day for comebacks at the Stuttgart Open, with number one seed Iga Swiatek recovering from a set down to beat Karolina Pliskova in the quarter-finals.

Swiatek made a disastrous start, going 4-0 down, and though she broke back once, was unable to find the second as Pliskova took the opening frame 6-4.

The determined Pole stepped up a level though to take the second 6-1, before breaking early in the third.

It was still an improvement for the Czech player, who lost 6-0 6-0 to Swiatek in their only previous meeting in Rome in 2021.

Pliskova kept her opponent honest on her own serve, but Swiatek had too much for the world number 17 as she clinched the decider 6-2.

Aryna Sabalenka also showcased her powers of recovery as she beat Paula Badosa despite going a set down.

The second seed won 4-6 6-4 6-4 in an even contest that saw nine breaks of serve, before the Belarusian eventually got over the line.

Sabalenka is now the player with the joint-most comeback wins over the last two seasons (13) level with Caroline Garcia, though the French star was actually the victim of a comeback herself on Friday.

Garcia won the first set against Anastasia Potapova, before the Russian came back to take it 4-6 6-3 6-3 to set up a semi against Sabalenka.

There was no need for such drama from Ons Jabeur, who eased to a 6-3 6-0 victory against Beatriz Haddad Maia in just 68 minutes to confirm a clash with Swiatek.

Iga Swiatek is through to the quarter-finals of the Stuttgart Open after easing to a 6-1 6-4 win over Zheng Qinwen on her return from a rib injury.

Swiatek had not played since sustaining the issue in the semi-finals of Indian Wells over a month ago, but advanced on Thursday despite stating that she felt "rusty".

The world number one won 84 per cent of points after landing her first serve in as she made up for lost time.

Swiatek also forced eight break points, winning four of them as she took just and hour and 26 minutes to set up a quarter-final with Karolina Pliskova, who bested Donna Vekic in a thriller.

Pliskova looked to be on her way to a routine win as she claimed the first set 6-2, only for the Croatian to take the second via a tie-break.

The decider also went the distance, with Pliskova able to finally put Vekic away 6-2 6-7 (5-7) 7-6 (7-5) to book her clash with Swiatek.

Coco Gauff perhaps paid the price for taking almost three hours to beat Veronika Kudermetova on Wednesday, as the fifth seed fell to a straight-sets loss to Anastasia Potapova on Thursday, going down 6-2 6-3.

Fourth seed Caroline Garcia will go up against Potapova next after she defeated Tatjana Maria 7-6 (7-5) 6-4, while Paula Badosa had few problems seeing off fellow Spaniard Cristina Bucsa 6-1 6-2 and will face second seed Aryna Sabalenka in the last eight.

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.

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.

World number five Ons Jabeur is through to the third round of the Charleston Open after making a winning start in a 6-3 6-3 triumph over Lesia Tsurenko on Tuesday.

Jabeur, a finalist at both Wimbledon and the US Open this past season, received a bye through to the second round thanks to her status as the second seed, and she had to save three break points in the opening game of the match against Tsurenko.

After repelling the early push, Jabeur rattled off the first five games to take a commanding lead, and she secured another break to begin the second frame.

Meanwhile, with half of the field still completing their first-round matchups, 12th seed Paula Badosa proved too strong for Egypt's Mayar Sherif in a comfortable 6-3 6-1 victory.

Spain's Badosa will play Canada's Leylah Fernandez in the second round after the promising 20-year-old took just 72 minutes to dispatch Russia's Evgeniya Rodina 6-3 6-2.

Rodina was the only loss from the four Russians in action on Tuesday, with Anna Kalinskaya defeating Alize Cornet 7-6 (7-4) 4-6 6-2, 19-year-old Diana Shnaider eliminating Alycia Parks 6-4 6-3, and Varvara Gracheva prevailing 7-6 (7-3) 6-2 against Anna-Lena Friedsam.

Bernarda Pera advanced past Clare Liu 6-4 6-7 (1-7) 6-3 in one of the all-American showdowns, while ninth seed Madison Keys beat Emma Navarro 6-4 6-3 and Shelby Rogers took out Danielle Collins 6-7 (2-7) 6-4 6-1 in the others.

Sofia Kenin, the 2020 Australian Open champion, handled the challenge of Aliaksandra Sasnovich 6-1 6-7 (5-7) 6-1, and two-time Australian Open champion Victoria Azarenka came back to defeat Sloane Stephens 3-6 6-3 6-2.

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.

Liudmila Samsonova progressed after a marathon battle at the Dubai Tennis Championships, while Petra Kvitova breezed through as the seeds escaped unscathed on Sunday.

Two-time Wimbledon champion Kvitova, the 12th favourite in the United Arab Emirates, eased past Italy's Martina Trevisan 6-2 6-1 to make a dominant start.

World number 15 Samsonova was made to work to beat Paula Badosa, winning 6-7 (3-7) 7-6 (7-5) 6-4 to tee up a clash with Qinwen Zheng, who overcame compatriot Zhang Shuai in straight sets.

Samsonova's triumph took three hours and 22 minutes, the longest match of the WTA Tour season thus far, in a thrilling first-round encounter between two top-20 players.

"Playing against Paula is always tough," 14th seed Samsonova said in her on-court interview. "She's doing unbelievable, so I'm really proud that I stayed on the court until the end.

"I think I'm growing match after match, day by day. I know it's a long journey, and I hope to continue like that."

Barbora Krejcikova, the 2021 French Open champion, cruised into the last 32 with a comfortable 6-4 6-2 victory over Irina-Camelia Begu as she aims to go one better than her runners-up finish two years ago in Dubai.

Another routine victory saw American Madison Keys ease past Jasmine Paolini 6-1 6-1, but there was no such luck for 2020 Australian Open champion Sofia Kenin.

She was dispatched 6-1 6-1 by world number 26 Marie Bouzkova, while Amanda Anisimova claimed a 6-3 6-2 win over veteran two-time grand slam finalist Vera Zvonareva.

Viktoriya Tomova had too much for Kaia Kanepi in a 6-3 6-1 success, with her reward a second-round clash against third seed Jessica Pegula.

World number four Pegula lost to the in-form Iga Swiatek in the Qatar Ladies Open final on Saturday, and Leylah Fernandez will face the Pole next after beating Julia Grabher 6-4 6-2.

Belinda Bencic will play Daria Kasatkina in the final of the Adelaide International 2, though neither of them had to play a semi-final.

Bencic was due to go up against Veronika Kudermetova in the second scheduled semi-final on Friday, only for the Russian to withdraw due to a hip injury.

It was a similar story for Kasatkina, who received a walkover after Paula Badosa pulled out of their match, citing a thigh problem.

While Bencic and Kasatkina will now get the chance to claim a trophy early in the season, the focus for Badosa and Kudermetova will be on regaining fitness in time for the Australian Open, which starts next week.

Badosa was confident she can recover for the upcoming major, where she has been drawn against American Caty McNally in the first round.

"I'm really disappointed that I had to withdraw because I was really looking forward to the match," Badosa told reporters.

"When I was playing [against Beatriz Haddad Maia], it was a very tough match, especially physical, so I felt a little bit in my abductor. I felt like I pulled it a little bit.

"I feel a little bit worse, so I have the Australian Open ahead, and I hope I can recover for that."

Badosa needed two hours and 35 minutes to get past the Brazilian on Thursday, having knocked off Anett Kontaveit and Kaia Kanepi in the earlier rounds.

"I played three really good matches," the Spaniard said. "I think that helps me, as well, on my confidence for the tournaments ahead. Now it's something that I cannot control, so it is what it is."

At the Hobart International, Elisabetta Cocciaretto set up a showdown with Lauren Davis.

Sofia Kenin, the 2019 champion, fell 7-5 4-6 6-1 to world number 67 Cocciaretto, who has reached her first Tour-level singles final.

"It’s unbelievable for me to be here in the final of such a great tournament, and I’m really happy about my performance," Cocciaretto said.

"[Kenin is] a very good player, I was a junior when she won the grand slam [2020 Australian Open], so for me it's an honour to play against her."

Davis, meanwhile, saw off Anna Blinkova in straight sets. She has not featured in a Tour-level final since clinching the trophy in Auckland in 2016.

Veronika Kudermetova saved five match points as she beat Danielle Collins to reach the Adelaide International 2 semi-finals before Belinda Bencic knocked Caroline Garcia out.

Sixth seed Kudermetova showed great defiance to defeat American Collins 4-6 7-6 (7-5) 6-1 on Thursday.

Kudermetova fended off five match points when serving to stay in the tournament at 6-5 down in the second set and duly forced a tie-break.

Collins, runner-up to Ash Barty in the Australian Open final last year, took a 3-0 lead in the breaker, but back came her Russian opponent to level the match.

The world number nine dominated the deciding set to seal a meeting with Bencic in the last four.

Eighth seed Bencic got the better of WTA Finals champion Garcia 6-2 3-6 6-4.

Garcia broke straight back after going 3-1 down in the final set, but Bencic broke for the fourth time in the match to go through.

Paula Badosa and Daria Kasatkina will contest the other semi-final after beating Beatriz Haddad Maia and Petra Kvitova respectively. 

Elisabetta Cocciaretto saved two match points as she came from a set down to beat Bernarda Pera 5-7 7-6 (10-8) 6-4 in the quarter-finals of the Hobart International. 

The 21-year-old Italian will now face 2020 Australian Open champion Sofia Kenin, who also stormed back to defeat Anhelina Kalinina 4-6 6-3 6-1.

Lauren Davis and Anna Blinkova will do battle in the other semi-final following wins over Wang Xinyu and Yulia Putintseva respectively.
