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.

Daniil Medvedev ended his wait for a first win over Roberto Bautista Agut at the Halle Open as his impressive start to the grass-court season continued.

The world number one, who reached the final at 's-Hertogenbosch last week only to suffer a shock defeat to Tim van Rijthoven, had not beaten Bautista Agut in three previous matches.

But his duck against the Spaniard is over following a 6-2 6-4 win, which set up a semi-final meeting with Oscar Otte after the German saw off Karen Khachanov in three sets.

"I remember all the matches we had… He was playing some [great] tennis and it was tough for me to win," Medvedev said of his previous meetings with Bautista Agut. 

"Today I had my plan, managed to keep it going. Definitely got more edge on the most important points, because he had more break points than me. It was not easy, and I'm happy to win."

Hubert Hurkacz, a Wimbledon semi-finalist last year, is also into the last four after edging Felix Auger-Aliassime in two tie-breaks and will face Nick Kyrgios, who beat Paulo Carreno Busta in straight sets.

Elsewhere, Matteo Berrettini was victorious at the Stuttgart Open and is on course to go back-to-back at the Queen's Club Championships after seeing off Tommy Paul 6-4 6-2 to progress to the semi-finals.

Botic van de Zandschlup is his next opponent, the Dutchman overcoming Alejandro Davidovich Fokina 6-2 6-4.

Meanwhile, Filip Krajinovic had to come from a set down to end Briton Ryan Peniston's run at the quarter-final stage, with his reward a meeting with former US Open champion Marin Cilic, a straight-sets victor over Emil Ruusuvori.

Rafael Nadal has confirmed he is planning to play at Wimbledon after proving his fitness during a week of training on grass in Mallorca.

The 22-time grand slam winner made his announcement in a news conference on Friday.

Nadal, 36, has won the Australian Open and French Open titles already this year and is halfway towards a possible sweep of the grand slams, a feat that was last achieved in men's singles by Australian Rod Laver in 1969.

Spaniard Nadal triumphed at Roland Garros despite needing pain-killing injections before every match, as he continues to battle a foot problem that has plagued him for much of his career.

Nadal said in Paris that he intended to undergo radiofrequency injections in a bid to ensure he could compete at the All England Club, and he has undergone two courses of such treatment.

Wimbledon starts on June 27, and it is a tournament that Nadal won in 2008 and 2010, although he has not played there since 2019, when he reached the semi-finals.

Speaking in Mallorca on Friday, Nadal said: "I have managed to reduce the pain. I am happy to have been a week without going lame.

"They have been somewhat different pains. We have to wait to see how it evolves in the next few weeks. My intention is to play Wimbledon.

"Two radiofrequency sessions have been done and the evolution has been satisfactory. I don't know what might happen in five days. For now, the treatment has allowed me to train and that has made me make the decision to fly to London."

Nadal has labelled the idea of a calendar grand slam sweep as "crazy", although Novak Djokovic came tantalisingly close last year, winning the Australian and French Opens and Wimbledon before losing to Daniil Medvedev in the US Open final.

He is optimistic the London courts could prove helpful to his prospects, if he can carry over his clay form to the grass.

"I don't think the grass hurts my foot more than other surfaces. From my point of view, the grass is softer than other surfaces," Nadal said.

"The only thing I can say is the week I have been practising here after my treatment has been positive, I have experienced some improvements, different feelings, in my foot and I take that as a positive thing.

"My goal or my intention is to travel to London next Monday, play two matches there before the tournament starts and follow my normal schedule to prepare the best possible way for Wimbledon.

"Today that's all I can say. What can happen in a couple of days, if the situation changes or becomes more negative, then that will be the moment to explain another thing. Today I am positive.

"I am excited to travel to Wimbledon to try to play Wimbledon after three years."

World number one Daniil Medvedev is through to the quarter-finals of the Halle Open after beating Ilya Ivashka in a routine straight-sets win.   Medvedev only played and defeated the Belarusian six days ago at the Rosmalen Grass Court Championships, and triumphed again as he came through in Germany 7-6 (7-4) 6-3.   After saving three set points to stay in the opening set, Medvedev sealed it on a tie-break, before easing through in the second.   "He is a great player," Medvedev said of Ivashka after the win. "He had a lot of bad luck with injuries at the beginning of the season. At the end of last season he was playing really great tennis.   "I've known him since I was very young, we actually played in Futures, Challengers, and on the ATP Tour. He beat me once in the Davis Cup, which is a really important tournament. So he knows how to play tennis, he knows how to play well on grass, so I'm really happy that two times in a row I managed to pass a tough test."   He will now play seventh seed Roberto Bautista Agut in the last eight after the Spaniard beat Tallon Griekspoor 6-7 (6-8) 6-4 6-2.   Eighth seed Karen Khachanov is also through after defeating Serbian Laslo Djere 7-6 (7-4) 6-4, and will face Oscar Otte after the German overcame Nikoloz Basilashvili 4-6 6-0 7-6 (7-3).

At the Queen's Club Championships, second seed Matteo Berrettini came from a set down to finally see off Denis Kudla, winning 3-6 7-6 (7-5) 6-4.

Defending champion Berrettini was troubled by the world number 82, and was just a tie-break away from suffering an upset, but the Italian came through as he belted down 22 aces in the match.

Berrettini faces Tommy Paul in the quarter-finals after the American beat Stanislas Wawrinka in straight sets, 6-4 6-1.

Ryan Peniston carried on from knocking out number one seed Casper Ruud by beating Francisco Cerundolo 6-0 4-6 6-4, setting up a last eight clash with Filip Krajinovic after he came from behind to defeat Sam Querrey 4-6 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.

A spirited fightback from Nick Kyrgios saw the Australian beat second seed Stefanos Tsitsipas in the Halle Open on Wednesday.

Kyrgios suffered a disappointing semi-final defeat to Andy Murray in Stuttgart last week, but looked greatly improved against Tsitsipas as he recovered from a set down to win 5-7 6-2 6-4.

It was the second serve of both men where Kyrgios shone, winning 76 per cent (28 of 37) of points on his second serve, and 58 per cent (23 of 40) on his opponent's.

"Stef is one of the best players in the world at the moment and he's going to have some amazing results and I'm sure many, many grand slams," Kyrgios said following his win.

"I don't know if I can say the same for me, but I'm happy to still be able to produce this level with the tournaments I play. It is a testament to how hard I do work when I'm not playing."

He will face Pablo Carreno Busta in the quarter-finals after the Spanish sixth seed beat Sebastian Korda 6-4 0-6 6-3.

Elsewhere, Hubert Hurkacz will face Felix Auger-Aliassime in the last eight after defeating Ugo Humbert 7-6 (7-5) 6-3, while the Canadian also won in straight sets against Mackenzie McDonald 7-6 (9-7) 6-1.

The one remaining first round match saw number one seed Daniil Medvedev beat David Goffin 6-3 6-2 to set up a second round clash with Ilya Ivashka.

At the Queen's Club Championships, sixth seed Denis Shapovalov was eliminated by Tommy Paul 6-4 2-6 6-4, with the American now scheduled to face Stanislas Wawrinka in the second round.

It means that six of the eight seeds in west London were knocked out in the first round, with Matteo Berrettini and Marin Cilic the only remaining seeds. The latter sealed his place in the quarter-finals on Wednesday with a 7-6 (8-6) 7-5 win over Alexander Bublik.

Cilic will play Finland's Emil Ruusuvuori in the last eight after he beat home favourite Jack Draper 6-2 7-6 (7-2).

The best contest of the day came between Alejandro Davidovich Fokina and Alex de Minaur, with the former coming from behind to win 4-6 6-4 7-5 to set up a quarter-final with Botic van de Zandschulp, who beat Grigor Dimitrov 7-6 (7-5) 6-3.

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.

Top seed Casper Ruud suffered a shock first-round exit at the Queen's Club Championships, going down in straight sets to British ATP Tour debutant Ryan Peniston in west London.

The French Open runner-up struggled to get going as he fell to a 7-6 (7-4) 7-6 (7-2) defeat to the world number 180, who was backed by a boisterous home crowd throughout.

Ruud struggled from the off as Peniston forced four break points in the Norwegian's first service game, and his miserable outing was rounded off when his opponent raced into a 5-1 lead before serving out a second-set tie-break.

After claiming the scalp of the world number five, Peniston told the BBC: "I can't really believe it. It feels like a dream. It doesn't feel real.

"I think I've been playing well. Casper is an unreal player and he did so well at the French Open, so I knew it was a tough ask. Four or five years ago I was sitting in the crowd just watching so to be here now is just unreal."

Ruud was not the only big name to fall at the first hurdle, with fifth seed Diego Schwartzman going down 6-1 6-4 against big-serving Sam Querrey to become the fourth of the top five seeds to fail to reach the round of 16.

Second seed and defending champion Matteo Berrettini is the exception after faring much better against another home favourite, cruising past Dan Evans 6-3 6-3, while Stan Wawrinka downed Francis Tiafoe 7-6 (7-2) 6-7 (6-8) 7-6 (7-5), and Denis Shapovalov's clash with Tommy Paul was suspended by darkness at one set apiece. 

Elsewhere, world number six Stefanos Tsitsipas progressed through his opening match at the Halle Open, beating Benjamin Bonzi 7-6 (7-1) 1-6 6-3 to set up an enticing last-16 clash with Nick Kyrgios, who bested Daniel Altmaier 6-3 7-5.

Fourth seed Felix Auger-Aliassime also progressed after being taken to three sets, beating Marcos Giron 6-3 5-7 6-3.

Meanwhile, defending champion Ugo Humbert will face a tough round-of-16 match against fifth seed Hubert Hurkacz after the Pole overcame Maxime Cressy 6-4 4-6 6-4. 

The US Open has announced players from Russia and Belarus will be allowed to compete in this year’s tournament despite the ongoing war in Ukraine.

The decision means world number one Daniil Medvedev can defend his title.

While the United States Tennis Association is allowing Russian and Belarusians to enter the tournament, the athletes must play under a neutral flag. The French Open, which concluded on June 5, allowed Russian and Belarusians to compete under the same conditions.

"Alongside the other grand slams, the ITF, the ATP and the WTA, the USTA, which owns and operates the US Open, has previously condemned, and continues to condemn, the unprovoked and unjust invasion of Ukraine by Russia," the USTA said in a statement.

"The USTA, standing with these other tennis entities, supported the banning of the Russian and Belarusian Tennis Federations from the ITF, and therefore all international team competitions, and the directive for players from those countries to play under a neutral flag when competing outside of international team competitions."

Since Russia launched its invasion of Ukraine in February, several organisations have banned Russian athletes from participating. Wimbledon, which starts on June 27, announced back in April that Russian and Belarusians would be barred from competing.

"We recognise that each organisation has had to deal with unique circumstances that affect their decisions," the USTA's statement read. "Based on our own circumstances, the USTA will allow all eligible players, regardless of nationality, to compete at the 2022 US Open."

The US Open begins on August 29 in New York.

Serena Williams has been handed a Wimbledon singles wild card after confirming her return from injury after a year out.

The 40-year-old has not played competitively since losing to Aliaksandra Sasnovich in the first round of last year's tournament at SW19 and is now ranked at 1,208 in the world.

Williams hinted at her imminent comeback in a social media post on Tuesday, however, and it has now been confirmed she will take part in the third grand slam of the year.

Twenty-three time major winner Williams will also compete in the upcoming grass-court event at Eastbourne after receiving a wild card in the doubles draw alongside Ons Jabeur.

That will act as preparation for Wimbledon, a competition she has won seven times, the most recent of those triumphs coming in 2016.

Williams is one major title shy of matching Margaret Court's long-standing record of 24, which has been the case since her most recent triumph at the 2017 Australian Open.

She missed last year's US Open on home soil, as well as this year's Australian Open and French Open.

In her earlier Instagram message, Williams posted an image of her trainers on grass and captioned it: "SW and SW19. It's a date. 2022, see you there."

American Williams joins 10 British players on the initial batch of wild cards for the Wimbledon singles, while three-time grand slam winner Stan Wawrinka will also take part.

Serena's sister Venus, a five-time singles winner at Wimbledon, was not named on the initial batch of wild cards but two spots remain up for grabs.

The tournament in London gets under way on June 27.

Serena Williams has appeared to confirm her intention to take part in this month's Wimbledon after a year out injured.

The 40-year-old has not played competitively since losing to Aliaksandra Sasnovich in the first round of last year's tournament at SW19 and is now ranked at 1,208 in the world.

Twenty-three time major winner Williams' future was called into question in April when long-time coach Patrick Mouratoglou announced he was working with Simona Halep.

However, she hinted around the same time that returning to action at Wimbledon was a possibility, and that news was all but confirmed on social media on Tuesday.

Williams posted an image of her trainers on grass and captioned it: "SW and SW19. It's a date. 2022, see you there."

She also tagged Eastbourne, where a WTA event takes place in the week before Wimbledon, which begins on June 27.

Williams has won seven Wimbledon titles, the most recent of those in 2016, having since lost in the 2018 and 2019 finals.

The American is one major title shy of matching Margaret Court's long-standing record of 24, which has been the case since her most recent triumph at the 2017 Australian Open.

She missed last year's US Open on home soil, as well as this year's Australian Open and French Open.
