Garbine Muguruza recorded a much-needed win to reach the last 16 at the Eastbourne International.

World number 10 Muguruza, who had only won two tour-level matches since the start of March, was tested in a gripping second-set tie-break by Magdalena Frech, eventually triumphing 6-1 7-6 (9-7).

After the victory, Muguruza said she was pleased to have overcome challenging weather conditions to reach the next stage, saying: "I feel like I fought hard against the wind, and I haven't played many matches on grass either.

"I could see today that if I didn't fight as hard as I can, I wasn't going to win."

A minor upset saw 17th seed Alison Riske slip to a 6-7 (3-7) 6-3 7-6 (7-4) loss to Magda Linette, while Yulia Putintseva surged to a 7-5 6-1 win over Sara Sorribes Tormo and seventh seed Barbora Krejcikova saw her contest with Marta Kostyuk halted by darkness at one set apiece.

Ajla Tomljanovic beat Aleksandra Krunic 6-0 4-6 6-3 and Heather Watson went down 7-6 (7-1) 6-4 to Canada's Rebecca Marino, as the Sussex crowds prepared for Serena Williams' eagerly anticipated doubles outing alongside Ons Jabeur on Tuesday.

There was frustration for Muguruza's fellow former Wimbledon champion Angelique Kerber at the Bad Homburg Open.

Kerber's match against Anastasia Gasanova got under way, but play was stopped due to fading light and a damp court after a rain-hit day. Third seed Kerber led 4-2 in the first set of a contest that will conclude on Tuesday.

The only other seed in action in Germany made routine progress, as France's Alize Cornet raced to a 6-2 6-4 win over Anna Kalinskaya.

Serena Williams will find it "super difficult" to challenge for an eighth Wimbledon singles title when she returns to SW19 next week, according to Karolina Pliskova.

Williams announced her participation at Wimbledon after receiving a wildcard last week, having been absent since a first-round retirement against Aliaksandra Sasnovich at The All England Club last year.

The American great will team up with Ons Jabeur to play doubles at Eastbourne over the coming days as the 40-year-old prepares for her Wimbledon return.

But Pliskova, who lost last year's Wimbledon final to Ashleigh Barty, says Williams could struggle to match her previous exploits after coming back from a long-term leg injury.

"I don't know how long it has been since she has played. Has it been a year? It is a long time, and she is not the youngest any more, so I suppose the body also takes some time to get back into shape," Pliskova said ahead of her own campaign at Eastbourne.

"Playing matches at tournaments is still very different to just practising and from what I understand, she is not playing [singles] here, she is just playing doubles.

"I think it will be difficult, super difficult for her, no matter what kind of player she is because this is a thing where you still need some time.

"But of course, she is an amazing player, she achieved so much and still a number of players will be super scared to play her. This is her advantage but let's see the level. I cannot really say."

Pliskova has won two of her three grand slam meetings with Williams, eliminating her at the quarter-final stage at the 2019 Australian Open and in the final four at the 2016 US Open.

While the world number seven may have cast doubt upon Williams' chances, Paula Badosa is not keen on the prospect of facing the 23-time major champion on the grass.

"I think it surprised everyone but it's very good to have her back. It really amazes me how she has all this hunger for the game," the world number four said.

"It is a great inspiration. It is nice to have her back and I hope she can be back for much more time because I think she does very good for tennis.

"But the other side, of course I don't want to play against her! I hope the draw goes for another player because no one wants to play against Serena and [even] less on grass. Let's pray for that!"

Ons Jabeur has announced she will not take part in the singles tournament at the Eastbourne International.

Jabeur will continue to play in the doubles, where she will pair with American legend Serena Williams, who has not played a competitive match since a first-round defeat at Wimbledon last year.

The news of the Tunisian's withdrawal from the singles tournament comes on the same day that she was elevated to world number three, after her victory at the Berlin Open on Sunday.

She beat Belinda Bencic in the final after her Swiss opponent retired with an ankle injury.

"I feel like I need to be smart about this decision," Jabeur told reporters about her choice not to play singles at Eastbourne.

Jabeur and Williams will face off against the unseeded duo Marie Bouzkova and Sara Sorribes Tormo in the first round on Tuesday.

Ons Jabeur hailed Serena Williams as a "legend" as she expressed her nervousness and excitement to pair with the American great at the Eastbourne International.

Williams has not played a competitive match since defeat to Aliaksandra Sasnovich in the first round of last year's Wimbledon and is now ranked at 1,204 in the world.

The 40-year-old, who is one grand slam title shy of matching Margaret Court's long-standing record of 24, will feature at the third grand slam of the year, which starts next Monday.

Eastbourne will serve as preparation for the upcoming grass-court major after Williams received a wild card in the doubles draw alongside Jabeur.

Jabeur has been in fine form in 2022, winning the Berlin Open and Madrid Open and rising to world number three, though she remains nervous to play with Williams at Eastbourne.

"I wanted to tell everyone, but obviously I couldn't," Jabeur told the WTA Tour in an interview. "I told my family, but even my close friends, I didn't tell anyone.

"Excited, really lucky that she picked me. I'm pretty glad that I can share the court with her. I always watched Serena playing and always supported her.

"She's such a legend and such an example for our sport. I'm really nervous to play. I hope the match will be great and we'll have great matches.

"I don't know why she picked me to be honest. Maybe she watched Madrid. I met her a few times outside the court and she was always nice.

"I remember exchanging pins with her in Rio. I respect her so much. I've been waiting for this moment for a long time. I had to take my time in Berlin, but now it's Eastbourne. I cannot wait for this moment."

Williams and Jabeur have been drawn against unseeded duo Marie Bouzkova and Sara Sorribes Tormo in the first round on Tuesday.

Former US Open champion Sloane Stephens suffered a shock first-round loss to world number 217 Katie Swan on day one of the Bad Homburg Open.

British player Swan, who will be competing on a wildcard at Wimbledon, scored a 2-6 6-4 6-2 victory over her American opponent.

Although Stephens has not been regularly hitting the heights of her 2017 Flushing Meadows triumph in recent seasons, the world number 48 would have fancied getting past Swan on Sunday.

The 23-year-old Swan needed a wildcard just to get into qualifying for this event in Germany, and she is due to play doubles alongside Stephens on Monday.

The match began well enough for Stephens, but Swan began to relish the matchup and levelled the contest before dominating the deciding set. Swan let three match points slip by, serving two double faults as the tension got to her, but the win was secured when Stephens drilled a forehand into the net.

Speaking in an on-court interview, Swan said: "It feels great. Sloane is an amazing player. She's a grand slam champion, and you can't get much better than that.

"We're actually playing doubles together tomorrow, so hopefully that'll be fun. I'm so happy to come through that one. It's my first tournament on grass not in England, so it's been fun so far, and it's probably my best result."

Other winners on Sunday in Bad Homburg included Caroline Garcia and Kamilla Rakhimova, who upset eighth seed Liudmila Samsonova.

At the Eastbourne International, where Serena Williams is due to make her tennis comeback by playing doubles in the coming days, first-round winners on Sunday included Marta Kostyuk, Kaia Kanepi and Sara Sorribes Tormo.

Poland's Magdalena Frech enjoyed a 6-3 6-0 stroll against Zheng Qinwen, the 19-year-old Chinese player who beat Simona Halep before causing Iga Swiatek plenty of problems at the recent French Open.

Beatriz Haddad Maia claimed back-to-back WTA Tour titles after Zhang Shuai retired hurt in the Birmingham Classic final on Sunday.

Haddad Maia enjoyed a fine day, beating second seed and two-time major champion Simona Halep 6-3 2-6 6-4 in a rearranged semi-final (postponed from Saturday due to rain).

Zhang followed that up by battling past Halep's Romanian compatriot Sorana Cirstea 4-6 6-1 7-6 (7-5), setting up a second career match with Haddad Maia.

The Brazilian struggled in the opening stages, with Zhang racing into the lead before squandering an opportunity to go 3-0 up.

Haddad Maia soon recovered to level at 3-3 before Zhang was forced to retire with an apparent neck injury, with the Chinese player 5-4 down in the first set.

That handed the world number 32 her second straight title after success at the Nottingham Open last week, with Ons Jabeur and Iga Swiatek the only others to record multiple WTA Tour triumphs this year.

Haddad Maia also became the first Brazilian lift the trophy in the tournament's 40-year history, surpassing the previous best result by a player from Brazil when Gisele Miro made the second round in 1989.

Ons Jabeur won the Berlin Open to seal her third career title following Belinda Bencic's retirement in the second set.

The win sees Jabeur rise to a career-high of number three in the world as the Tunisian – who was winning  6-3 2-1 when Bencic succumbed to an ankle injury – capitalised on her top seed position for the tournament.

With Jabeur on serve to clinch the first set, Bencic rolled her ankle and required treatment in a three-minute medical timeout – with Jabeur swiftly nosing herself ahead on the restart with an ace.

Olympic gold medallist Bencic pushed to continue but came to the net to retire when trailing 2-1 in the second set, taking Jabeur's tally of wins in 2022 to 30, a total that is only bettered by world number one Iga Swiatek.

Victory marked Jabeur's second title of 2022, with the 27-year-old having previously won the Madrid Open.

Jabeur had plenty of support from the crowd throughout the tournament, and said: "I cannot forget how amazing the crowd is, Tunisians are amazing, thank you for coming. I hope I can come back next year, it's been great to come back to Berlin."

Bencic paid tribute to her opponent following the game, saying: "You deserve this title, I really don't want to take this moment away from you because I think you played incredible tennis.

"This is the best tennis of your life, so I hope you continue. You gave me a really hard time, maybe it was one serve too much for me. This is your moment so I want you to enjoy it and focus on your title."

Jabeur continues her Wimbledon preparations at Eastbourne next week, competing in both the singles and doubles event – she will play alongside Serena Williams – while Bencic will be hoping to recover in time to feature in the season's third grand slam.

Ons Jabeur kept Coco Gauff waiting for a top 10 debut as the Tunisian battled past her teenage opponent to reach the Berlin Open final.

Gauff would have secured a career-high ranking on the WTA list if she had won Saturday's semi-final, but top seed Jabeur took it 7-6 (7-4) 6-2 to earn a shot at Belinda Bencic in the title match.

Only world number one Iga Swiatek has won more matches on the WTA Tour than fourth-ranked Jabeur this year, who collected a 29th win as she overcame a 3-1 career head-to-head deficit against Gauff to earn the victory.

Gauff, at 18 years and 98 days, would have become the youngest American to reach a grass-court singles final on tour since Andrea Jaeger was runner-up to Martina Navratilova at Wimbledon in 1983.

It was not to be her day though, Jabeur breaking serve for the fourth time in the match to seal victory, encouraged by a large and vocal Tunisian following.

Reflecting on the match, Jabeur said: "When you play Coco you have to have all the shots. She's a talented player; she's very tough to beat. You can see I've lost already three times against her.

"Sometimes she takes it, sometimes I take it, and it was a great match for both of us."

This is just the second WTA tournament where 27-year-old Jabeur has been a top seed.

"I've tried to act like a number one seed on and off the court, and it's a good pressure," she added. "I'm trying to handle it very well and with the support of our Tunisian people here it's great."

Olympic gold medallist Bencic had earlier claimed an impressive 6-7 (6-8) 6-4 6-4 win over Greek second seed Maria Sakkari in the first semi-final.

Jabeur was bettered by Bencic in a hard-fought Charleston final in April, but is determined to secure a different outcome this time.

"I'm definitely going for the final revenge because we played each other at Charleston, and it was a very, very tough match," Jabeur said. "I hope she's tired from today's match."

Rain meant there was no play at the Birmingham Classic on Saturday, with the semi-finals set back to Sunday.

Beatriz Haddad Maia will face 2019 Wimbledon champion Simona Halep, while Zhang Shuai tackles Sorana Cirstea.

Naomi Osaka pulled out of Wimbledon on Saturday as tournament officials said the former world number one was suffering with a leg injury.

The announcement came in the wake of Osaka revealing she was considering skipping the grand slam in any case, as she suspected it may feel "like an exhibition".

The All England Club's decision to ban Russian and Belarusian players from competing has resulted in the WTA and ATP stripping Wimbledon of all ranking points.

Osaka, who is a four-time grand slam champion, suggested after her first-round exit at the French Open that she was unsure about whether to commit to the grass-court major.

Confirmation of her absence from the event, which starts on June 27, came from Wimbledon as her name was added to a list of withdrawals.

The Japanese 24-year-old has only played Wimbledon's main draw three times in her career, twice reaching the third round. She has yet to go further but has won the Australian Open twice and the US Open on two occasions. Recently she complained of a "stubborn" Achilles problem.

Osaka was joined on the withdrawal list by Eugenie Bouchard, the 28-year-old Canadian who was runner-up to Petra Kvitova at the 2014 Wimbledon championships.

Wimbledon listed Bouchard as absent due to a shoulder problem; however, that told only part of the story.

She is battling her way back up the rankings after injury and disappointing results and said she could not risk using a special entry dispensation on a tournament that will carry no points.

Bouchard wrote on Instagram: "I have decided to withdraw from Wimbledon due to the WTA's decision to not award ranking points at this year's championships.

"Due to my shoulder surgery, I get a limited number of protected ranking [PR] entries. As much as I love Wimbledon and skipping it makes me sad, using a PR entry at a tournament with no ranking points doesn't make sense. I must choose wisely and use my PR at tournaments that will help me get back to where I want to be."

She said she would use her protected ranking grand slam entries for the next US Open and Australian Open.

Coco Gauff reached the first grass-court semi-final of her career by beating Karolina Pliskova at the Berlin Open, teeing up a clash with top seed Ons Jabeur.

Having already recorded her best tour-level run on grass by reaching the final eight, Gauff recorded a superb 7-5 6-4 win over two-time grand slam finalist Pliskova.

Gauff – who reached her first grand slam final at Roland Garros last month, saved four set points in the opener before roaring to victory in one hour and 37 minutes, and was delighted to have overcome a tough opponent in the world number seven.

"I'm super happy with how I played today," Gauff said on court after the win. "Playing her on grass, with her serve, how flat she hits the ball, it was really tough to be honest. 

"A first semi-final on grass is pretty cool, and also I feel like the opponents I've played this week haven’t been easy, especially today, so I'm proud of myself about that."

Gauff will face Jabeur for a spot in the final after the Tunisian fought back from one set down in a 6-7 (3-7) 6-2 6-2 win over Aliaksandra Sasnovich, who entered the contest having won 26 matches during an impressive year.

The other semi-final will see Maria Sakkari face Belinda Bencic, after the world number six cruised to a 6-0 6-3 win over Daria Kasatkina and Bencic beat Veronika Kudermetova 3-6 6-3 6-3.

In the Birmingham Classic, meanwhile, Simona Halep raced to a 6-4 6-1 win over Katie Boulter to reach the final four, but third seed Camila Giorgi fell to a 6-3 6-2 loss to Brazil's Beatriz Haddad Maia, who has now won eight consecutive games on grass.

While that pair will face off in one of Saturday's semi-finals, eighth seed Zhang Shuai will face Sorana Cirstea in the other. Zhang overcame Dayana Yastremska 7-5 6-4 and sixth seed Cirstea beat Donna Vekic 5-7 6-3 6-4.

Ons Jabeur held off qualifier Alycia Parks to reach the quarter-finals of the Berlin Open, saving set point before winning a competitive second-set tie-break to set up a last-eight clash with Aliaksandra Sasnovich.

Jabeur took one hour and 31 minutes to overcome her stubborn opponent in the German capital, with the world number four triumphing 6-2 7-6 (10-8) to reach her eighth quarter-final of 2022 – each of which have been at WTA 500 level or higher.

The Tunisian will face Sasnovich for a semi-final spot next time out, with the Belarusian having won 26 matches so far this year (including qualifying draws). Only Iga Swiatek (42) and Beatriz Haddad Maia (29) have more victories so far this season on the WTA Tour.

The other seeds in action in Berlin on Thursday also progressed, with Coco Gauff overcoming Wang Xinyu 6-0 6-4 to tee up a clash with Karolina Pliskova, and Belinda Bencic downing Anna Kalinskaya 6-4 1-6 6-1.

Defending champion Ludmilla Samsonova, however, suffered a 6-3 6-7 (5-7) 6-1 defeat to Veronika Kudermetova.

Meanwhile, the Birmingham Classic's top seed Jelena Ostapenko fell to a surprise 3-6 7-5 7-5 last-16 reverse against Ukraine's Dayana Yastremska, who reached her first ever grass-court quarter-final on the WTA tour.

The world number 79 will face Zhang Shuai for a spot in the final four after she fought her way to a 6-2 2-6 7-5 win over Elena-Gabriela Ruse.

Third seed Camila Giorgi will join them in the last eight after recovering from losing her first set against American Lauren Davis to secure a 3-6 7-5 6-2 win.

Rafael Nadal was stepping up preparation for Wimbledon by training on Mallorca's best grass courts on Thursday, an apparently positive sign that he intends to play in London.

The Australian Open and French Open champion said after his Roland Garros triumph at the start of June that he would only appear at Wimbledon if he could compete without needing anaesthetic injections in a troublesome foot.

The 36-year-old said he was given a couple of injections before every match and announced he would undergo radio frequency injections in a bid to feature at the third grand slam of the year.

Nadal is halfway towards a potential sweep of the four majors, defying the foot trouble by producing results that few saw coming. Rod Laver in 1969 was the last man to win all four singles majors in a calendar year.

Spaniard Nadal was pictured by organisers of the Mallorca Championships on Thursday, during a practice session on one of the tournament's plush courts.

Nadal, who hails from the island, is reluctant to undergo major surgery to prolong his career.

Wimbledon starts on June 27, and it is a tournament that Nadal has won twice, in 2008 and 2010.

He leads the all-time list of men's grand slam singles title winners, with 22 to his name now, two more than Roger Federer and Novak Djokovic have managed.

That is still one fewer than Serena Williams has managed during her stellar career, and the 40-year-old American rolled in to London on Thursday for another tilt at Wimbledon.

Due to injury, Williams has not competed on the WTA Tour since last year's championships at the All England Club.

She has received a wildcard into Wimbledon, where she has been a champion seven times, most recently in 2016.

Williams posted a video on Instagram of her arriving in London with daughter Olympia.

She intends to compete in doubles at Eastbourne, partnering Ons Jabeur, in the week leading up to Wimbledon.

Serena Williams' return to Wimbledon represents a "great example" to other players, according to Nick Kyrgios, who said tennis fans should not take her or other fellow greats Roger Federer, Rafael Nadal and Novak Djokovic, for granted.

Comparing the quartet to four-time NBA MVP LeBron James, Kyrgios says sports fans should enjoy the legends' "amazing" exploits while they still can.

It was confirmed on Tuesday that Williams – who has not played competitively since losing to Aliaksandra Sasnovich at Wimbledon last year – has been handed a singles wildcard to compete at the year's tournament, which begins later this month. 

Williams, now aged 40 and ranked 1,208th in the world, has won seven singles titles at Wimbledon, the last of which came in 2016, and 23 grand slams in total.

Simona Halep eased into the last eight of the Birmingham Classic with a straight-sets win over Harriet Dart.

Home hope Dart was looking for a second successive quarter-final, having beaten Donna Vekic and Camila Giorgi in Nottingham last week en route to a place in the last eight.

However, Halep illustrated the gulf in class between the two in her last-16 clash with Dart, surging to a 6-3 6-2 victory as she prepares to try to regain the Wimbledon title she won in 2019.

The second seed will next face another Briton, Katie Boulter, who beat Caroline Garcia in straight sets. Halep's Romanian compatriot Sorana Cirstea overcame Aleksandra Krunic, while there were also wins for Giorgi, Zhang Shuai and Vekic.

At the German Open, fourth seed Karolina Pliskova needed two hours and 11 minutes to see off former US Open champion Bianca Andreescu.

The Czech came through a marathon third set that went to a tie-break, Pliskova having been a break down at 3-1 in the third, prevailing 6-4 2-6 7-6 (9-7).

Pliskova broke Andreescu to level the decider at 5-5 and then saved two break points in her subsequent service game before converting her third match point in the tie-break.

It marked Pliskova's first complete win over Andreescu, her only previous success coming via retirement at the 2019 WTA Finals.

"Of course Bianca is a super-tough opponent, she can really give you anything," Pliskova said after the match. "Slices, she can play fast, she can serve really well, she can come to the net.

"So I think there was a little bit of everything in this match. I'm super proud that I was able to turn the match around, because I was losing in the third set. I thought she was a little bit better in the second and third sets, but I stayed in there and I fought and I got my chances in the end."

French Open runner-up Coco Gauff had an easier time of things in her opening match in Berlin, defeating Ann Li 6-2 7-6 (7-2).

Maria Sakkari got the better of Daria Saville 6-1 7-5, Daria Kasatkina came back from a set down to knock out Ekaterina Alexandrova 5-7 6-1 6-1 and Aliaksandra Sasnovich saw off Andrea Petkovic 6-4 6-4.

Berlin Open top seeds Ons Jabeur and Maria Sakkari progressed with relative ease from their first-round matches, but Aryna Sabalenka and Garbine Muguruza were not so fortunate.

World number four Jabeur, who will team up with Serena Williams at the Eastbourne International, suffered a shock first-round exit at the French Open, but the Tunisian showed no signs of that defeat having affected her in her first grass-court appearance of the season.

Top seed Jabeur required just 73 minutes to overcome Karolina Muchova 6-3 6-3 on Tuesday, with American qualifier Alycia Parks next up after she defeated Qinwen Zheng in straight sets.

Second seed Sakkari, meanwhile, had a similarly comfortable start to her campaign, beating Leolia Jeanjean 6-3 6-2.

Meanwhile, reigning champion Liudmila Samsonova took her place in round two with a 7-5 6-1 victory over Tamara Zidansek.

Samsonova beat Belinda Bencic to claim the title in 2021, and the pair will meet again the quarter-finals should they win respective second-round ties against Veronika Kudermetova and Anna Kalinskaya.

But Kudermetova goes into her clash with Samsonova on a high, having eliminated third seed Sabalenka in a 2-6 7-5 6-4 comeback victory.

WTA Finals champion Muguruza will not be in round two after the Spaniard fell foul of Germany's Andrea Petkovic, who prevailed 7-6 (10-8) 6-4.

"I really do believe that in these really close matches, the simple and little shift of energy can make the difference," Petkovic said.

"If you have the crowd on your side, and they are willing you to the win somehow, I think that can really make a difference."

At the Birmingham Classic, top seed Jelena Ostapenko booked a second-round meeting with Dayana Yastremska.

While Yastremska beat Magda Linette in straight sets, Ostapenko was made to work, with the Latvian requiring two hours to overcome Canada's Rebecca Marino 6-2 5-7 6-3.

Fourth seed Elise Mertens was ditched out by Caty McNally, while former world number two and two-time major champion Petra Kvitova lost to Beatriz Haddad Maia.

Camila Giorgi, the third seed, leads Tereza Martincova after claiming a close first set 9-7 in the tie-break before the match was suspended.
