Andy Murray's management team have confirmed the Briton will partner Serena Williams in this year's mixed doubles at Wimbledon.

Maria Sharapova cited a recurrence of a tendon injury in her left forearm after withdrawing from her opening-round match at Wimbledon while trailing 5-0 to Pauline Parmentier in the third set.

Sharapova, who only recently returned from shoulder surgery, fought back from a set down against Parmentier on Tuesday but proved uncompetitive in the decider.

Explaining her withdrawal in a subsequent news conference, the 2004 Wimbledon champion said: "I've had a history of a tendon in my left forearm flaring up. It happened today in the second set.

"It's very rare that I withdraw from a match in the middle of the match. That certainly means that it's painful, yeah."

Sharapova added: "For me to withdraw ... I don't want to put anyone in that position. I'm here to play. I don't want to be in this pain.

"Next time I come here, I want to feel great. I want to do what I'm meant to be doing at the level I believe I can."

Asked when she plans to return to action, the Russian replied: "I don't know yet. It's kind of a tricky injury. I've had this before.

"I haven't really gotten a really good clarification from anyone that I've seen on what really causes it."

Ashleigh Barty insists she is feeling no added pressure at Wimbledon in her first tournament as the world number one.

The French Open champion succeeded Naomi Osaka as the WTA Tour's top-ranked player at the Birmingham Classic, with the Japanese having endured a miserable stint since her Australian Open success in January.

Osaka acknowledged ahead of Wimbledon the role of number one brought "way more stress and pressure than I could have imagined" and her poor form continued with a first-round defeat at the All England Club on Monday.

But Barty triumphed against Zheng Saisai in straight sets the following day and appears keen not to worry about her ranking.

"I think, for me, it's a little bit irrelevant," she said after the 6-4 6-2 win. "The only pressure I have is what I put on myself, making sure I'm doing all the right things, preparing in the right way.

"Ultimately, when we play our matches, we go out there and enjoy it. That's why we do all the work, all the practices, to go out there and enjoy competing."

She added: "The first round is always very tough. It took time to get used to the conditions and the beautiful court with the new roof.

"It feels incredible. It is a little bizarre [to be number one], but this sacred turf we get to play on, you have to enjoy every minute of it."

Barty will not look too far ahead, either, or allow herself to dream of a second consecutive grand slam title just yet.

"For me, it's a possibility," the Australian said. "But it's certainly not something we're thinking about.

"It's about going match by match, trying to do the best that I can in every single tennis match that we play here. If we can give ourselves the opportunity, that would be great."

Serena Williams began her 19th Wimbledon campaign with a straight-sets win, but understandably looked some way below her brilliant best as she beat Giulia Gatto-Monticone 6-2 7-5 on Centre Court.

A seven-time champion at the All England Club, Serena started her bid for another title 24 hours after her sister Venus had been condemned to a shock defeat at the hands of 15-year-old Cori Gauff.

There never appeared any danger of the younger Williams sibling suffering a similar fate against Gatto-Monticone, a 31-year-old Italian who has never won a grand slam match or even recorded a victory over a top-100 player, yet this was from a vintage Serena performance, which perhaps comes as no surprise given her lack of competitive action in recent months.

Williams, who spoke confidently about her fitness ahead of this event after enduring an injury-plagued 2019 to date, raced into a 5-0 lead with her unheralded opponent looking painfully out of her depth on the big stage.

To her credit, though, Gatto-Monticone - playing with heavy strapping on her left knee - avoided the indignity of being bagelled in the opening set before raising her level to remain on serve through six games of the second.

While the qualifier fully deserved the warm applause she received for prolonging the contest, it was clear Williams was not firing on all cylinders.

The 11th seed eventually opened up a 5-3 lead, but surprisingly failed to serve out the match in the next game and was duly pegged back to 5-5.

An increasingly expressive Williams let out an enormous roar after winning the first point of the next game and then broke to seal victory, wrapping things up by winning a prolonged exchange at the net to end arguably the most entertaining point of the match.

She will know much stiffer tests await as she looks to secure a record-equalling 24th slam singles crown, with 18-year-old Kaja Juvan awaiting in the second round.

Lindsay Davenport believes Naomi Osaka looks "lost and overwhelmed" after the two-time grand slam champion exited Wimbledon in the first round.

Osaka triumphed at both the US Open and the Australian Open but then saw her form desert her after becoming world number one in Melbourne.

She has not won a WTA Tour title since and followed up a third-round French Open defeat against Katerina Siniakova by losing to Yulia Putintseva in straight sets at the All England Club on Monday.

Osaka suggested before Wimbledon that she was glad to be out of the spotlight having lost her ranking to Roland Garros champion Ashleigh Barty, yet she again struggled in London.

And 1999 Wimbledon champion Davenport hopes Osaka can adjust and return to form soon.

"It's been hard to watch Osaka play from about mid-February of this year," she told Omnisport, speaking courtesy of HSBC, supporter of the Wimbledon Foundation's Official Ticket Resale Scheme.

"It was one of the most exciting stories to see her in New York last year, to see her in Melbourne this year, to see her get her second grand slam.

"She looks a little bit lost right now and, I think, a little bit overwhelmed from all the fame that came her way from being a two-time grand slam champion, a lot of endorsement deals, a lot of outside interest in her now.

"I think she's struggling to kind of understand her new world. And hopefully it translates to her improving on the tennis court. Everybody wants to see Osaka playing her best, happy, out on court, winning matches.

"But it just looks like right now it's one of those tough times. And everybody knows she's going to come back stronger. I just hope that it's sooner, rather than later."

Davenport believes Barty will be able to deal with the same pressure, though, backing her to win at Wimbledon.

"I think it's very possible Ash Barty wins her second grand slam here, and her second in a row," she said.

"Clay is her worst surface. She surprised everybody by being able to win the French. This is actually the time of year she wants to play her best.

"She thinks she's a great grass-court player, she likes to come to net, she's got a great game. I think it's very likely that she wins two in a row.

"That top portion of the draw, though, is very tough - with [Angelique] Kerber also in her section, Serena [Williams] as well. They were calling it, in the women's side, the 'group of death'.

"We'll see who's able to come through there, but I love Ashleigh's game, love how she's been able to handle it all.

"We've seen Osaka, seen all the pressure she's felt being the world number one and a grand slam champion. So far it hasn't hit Barty. That's a great sign, she's so relaxed about it."

Angelique Kerber solved the problem of the Tatjana Maria forehand slice as she began her Wimbledon title defence with a straight-sets win on Centre Court.

An all-German battle juxtaposed the conventional game of left-hander Kerber with the peculiar sight of Maria repeatedly swishing squash shots across the net, often drawing unusual spin and swerve.

Kerber broke serve seven times, but the 31-year-old was outfoxed on her own delivery four times while battling to a 6-4 6-3 first-round victory.

Although born just five months apart, compatriots Kerber and Maria have barely encountered each other on court.

Their one previous meeting came on clay in qualifying at Barcelona in 2009, and went Maria's way, yet that was hardly a gauge of how this match would run.

Kerber landed her third grand slam singles title last year at Wimbledon, surprising many with the way she soundly beat Serena Williams in the final.

She has not won a title since but a run to the Eastbourne final last week, despite losing out to Karolina Pliskova for the trophy, appeared to bode well for this fortnight.

The first set was wrapped up with a terrific lob on the run, and Kerber made sure of the win with a powerful two-handed backhand down the line that Maria could only jab wide.

In the closing stages an entertaining rally had seen Kerber play a gratuitous exhibition shot between her legs, only to be trumped by a stop volley from Maria.

It was that sort of match, unpredictable in all areas but for the outcome.

Ashleigh Barty enjoyed a winning start to life as the world number one, beating Zheng Saisai 6-4 6-2 in her Wimbledon opener on Tuesday.

Playing for the first time as the WTA Tour's top-ranked star, Barty came through a nervy first set to saunter through on Court No.1 at the All England Club.

The French Open champion showed no signs of the arm injury that kept her out of the Nature Valley International as she dictated play in the second.

With victory, Barty avoided following previous number one Naomi Osaka out of the competition and instead booked a second-round meeting with Alison van Uytvanck.

After the upsets of the opening day's play, with Venus Williams also beaten by 15-year-old Cori Gauff, Barty sought to swiftly ensure she would not similarly fall foul of a more modest opponent.

And the Australian led early when Zheng sent a forehand wide to the left.

But that advantage was cancelled out in a fifth game that saw Zheng create three break-point opportunities, finally converting when Barty followed up a meek drop shot at deuce with a wayward close-range effort.

Barty dug in brilliantly, though, and took the set with a straightforward break to love at the end of a testing stretch.

Then, as in the opener, the top seed turned up the heat on Zheng right away to lead following an extended second game and this time gave the Chinese no opportunity to respond.

A second Barty match point was then seized with a superb stretching return on Zheng's serve to complete victory in straight sets.

Cori Gauff was in dreamland after the 15-year-old sent shockwaves around Wimbledon by beating Venus Williams, while an emotional Naomi Osaka crashed out on day one.

Gauff became the youngest player to qualify for the grass-court grand slam in the Open Era last week and stunned her idol Williams 6-4 6-4 in her first main-draw match at a major on Monday.

Osaka was unable to join American prospect Gauff in round two, Yulia Putintseva beating the second seed 7-6 (7-4) 6-2 at the All England Club.

Magdalena Rybarikova will be teenager Gauff's next opponent after the Slovakian toppled 10th seed Aryna Sabalenka 6-2 6-4.

Simona Halep was troubled by her knee and Achilles, but the former world number one battled past Aliaksandra Sasnovich 6-4 7-5, while third seed Karolina Pliskova and eighth seed Elina Svitolina defeated Zhu Lin and Daria Gavrilova respectively.

Caroline Garcia, Marketa Vondrousova and Daria Kasatkina were the other seeds to fall on the opening day at SW19.

 

CLASSY GAUFF EXPRESSES VENUS GRATITUDE

Gauff produced an astonishing performance on the renovated No.1 Court and the world number 313 was reduced to tears after dumping out 39-year-old Williams.

Williams had won Wimbledon twice by the time Gauff was born, but it was the youngster who came out on top in the battle of the generations after making only eight unforced errors.

"This is the first time I ever cried after winning a match," Gauff told BBC Sport. "I never thought this would happen. I don't know how to explain it. I'm literally living my dream. Not many people get to say that.

"When we shook hands she told me congratulations and to keep going and good luck. I said, 'Thank you for everything you've done.' I wouldn't be here if it wasn't for her."

 

ALL TOO MUCH FOR OSAKA 

Osaka cut her press conference short after losing to an inspired Putintseva as the two-time major champion was "about to cry."

The Kazakh maintained her perfect record against the US Open and Australian Open champion with an inspired display, Osaka paying the price for 38 unforced errors.

The Japanese struggled on grass once again in a tournament where she has not been beyond the third round, losing to Putintseva for the third time last than two weeks after she got the better of her in Birmingham.

 

HALEP 'LUCKY' TO AVOID SERIOUS INJURY

Seventh seed Halep fell awkwardly during her encounter with Sasnovich on the same court where Gauff later stunned Williams.

The 2018 French Open champion needed treatment after overextending when she fell to the turf but was able to solider on with her left ankle strapped.

Romanian Halep said: "It's okay in this moment. But I need to do the treatment. I feel a little bit. I think it's a little bit stretched, the muscle behind the knee, and also the Achilles. Hopefully is nothing dangerous and I can recover until the next match [against compatriot Mihaela Buzarnescu]."

History-making 15-year-old Cori Gauff showed astonishing maturity to secure a sensational victory over her idol and five-time champion Venus Williams on day one at Wimbledon.

Gauff became the youngest qualifier at the All England Club in the Open Era last week and is through to the second round after stunning fellow American Williams 6-4 6-4 on Monday.

Williams had won the grass-court grand slam twice before her compatriot was born, but the 39-year-old was unable to live with the teenager, who became the youngest female to win a singles match at Wimbledon since 1991.

Gauff was totally unfazed in her first match in the main draw at a major, serving brilliantly, showing great athleticism, hitting 18 winners and making only eight unforced errors in a magnificent performance on the renovated No. 1 Court.

The 313-ranked teenager boldly stated she wants to be "the best of all time" ahead of the biggest match of her life and produced one of the most impressive grand slam debut displays.

Gauff, the junior French Open champion last year, claimed the only break of the first set after showing great defence before Williams drilled a backhand wide to go 3-2 down.

She served out the set in a manner befitting her veteran opponent and maintained her intensity in the second set, a double fault from Williams gifting her a 3-2 lead.

They were back on serve when Gauff double faulted to be pegged back at 4-4, but she broke again in the next game and kept her composure to send shockwaves around SW19 with a monumental victory after Williams saved three match points.

Gauff will face world number 139 Magdalena Rybarikova in round two.

Second seed Naomi Osaka was the first major casualty at Wimbledon on day one, losing in straight sets to an inspired Yulia Putintseva.

Putintseva has never been beyond the second round at the All England Club, but stunned a nervy Osaka with a 7-6 (7-4) 6-2 victory on Monday.

The 39-ranked Putintseva won her previous two encounters with Osaka - most recently in Birmingham last month - and sent the world number two packing on Centre Court.

US and Australian Open champion Osaka racked up 38 unforced errors, struggling badly on grass once again at a grand slam where she has not been past round three.

Kazakh Putintseva capitalised on an uncertain display from Osaka, making just seven unforced errors and breaking three times to move into the second round.

While there were 34 winners from Osaka, the 21-year-old from Japan bowed out in an hour and 35 minutes at the All England Club. 

Osaka led 3-1 in the opening set, but Putintseva won the next three games and also stormed back from 3-1 down in the tie-break.

Putintseva allowed Osaka just a solitary break-point opportunity in the second set and won five games in a row to claim the biggest victory of her career, Osaka heading for the exit after netting a backhand.

Angelique Kerber insists she is not concerned by the Wimbledon draw despite potential meetings with Serena Williams and Ashleigh Barty en route to the last four.

Defending champion Kerber could meet 23-time grand slam winner Williams in the fourth round, while world number one Barty, fresh from taking the French Open title, is a possible quarter-final opponent.

However, Kerber is not paying too much attention to her path to the latter stages of the tournament, determined to focus on each rival in turn.

"It's nothing new for me, to be honest," she said. "Right now, the first round is important.

"What's in the second round, third, fourth, whatever, it doesn't matter right now. The most important thing is to play the first round, then looking ahead day by day.

"Anything can happen, especially in grand slams. Of course there are always tough opponents. You have to beat everyone if you would like to win a grand slam.

"I know a little bit but not everyone - I just know Serena is there, I heard it everywhere. But the first round is the important one."

Naomi Osaka and Barty have both made breakthroughs at majors in the past 12 months, while there were two teenage semi-finalists at the French Open.

But Kerber still believes Williams - who she beat in last year's Wimbledon final - has to be considered among the chief threats in the coming weeks.

"Serena is one of the best players in the world. She is a champion," said the German.

"To see how she is still competing and trying to come back, trying to play her best tennis, she is one of the toughest opponents to beat. She has the experience.

"Of course, young players are coming, the next generation is coming, but this is just normal. She is still one of the best ones."

And Kerber suggests the experience she and Williams boast could be key at the All England Club.

"The draw is really open and there are a lot of young players coming," she said. "But mentally, the experience of playing a lot of matches on grass is completely different to the other surfaces.

"And here you feel a completely different energy. When you come here, you have pressure and the nerves are much higher than usual."

Petra Kvitova expects to be able to play at Wimbledon after testing an arm injury on the All England Club practice courts.

The 2011 and 2014 women's singles champion came to London with questions over her readiness to compete.

She has not played for six weeks, abandoning a match in Rome due to injury and then pulling out of the French Open.

A grade two tear in her left forearm - Kvitova is a left-hander - has been the problem, but she feels increasingly optimistic about taking part in Wimbledon.

The Czech is due to begin her campaign on Tuesday against Tunisian Ons Jabeur, who reached the Eastbourne semi-finals before an ankle blow caused her to pull out.

Kvitova told BBC Sport: "I had some doubts about whether I would play at Wimbledon but my arm is better, which is great.

"The tear in my forearm has been an unusual injury - nobody knows how it is going to be and how much time I will need to be ready again.

"I had a few MRI scans during the period when I couldn't hit and it didn't show that it's 100 per cent ready but sometimes in our life, nothing is really ready!"

She reported "no pain" after a practice on Saturday, but said: "Of course, if I do have pain in my arm I won't play. So far it's okay - there's a few more days so anything can happen."

Kvitova, 29, was attacked in her home by a knife-carrying intruder in late 2016 and suffered serious injuries to her left hand.

She would love to win a third Wimbledon title, even if she admits her preparation this year has been far from ideal.

She said: "My expectations here are not really high but maybe this can help me relax more on court."

Venus Williams will tackle record-breaking teenager Cori Gauff on Court One in an all-American battle of the generations at Wimbledon on Monday.

Five-time former SW19 champion Williams, 39, was drawn on Friday to face the youngest player to ever come through the women's singles qualifying rounds.

Gauff has cited Venus and sister Serena as inspirations behind her career, and the Florida-based 15-year-old has enjoyed success in junior grand slams.

The biggest test of her fledgling career is also rated by many as the most eagerly anticipated match of the opening day at the championships, however it misses out on Centre Court billing.

But a slot third on the second largest court means, with a likely late-afternoon start in London, it should attract a strong television audience both in the UK and the United States.


Novak Djokovic, as the defending men's champion, is handed the customary honour of getting action under way on Centre Court when he faces German veteran Philipp Kohlschreiber.

Japanese world number two Naomi Osaka plays Kazakhstan's Yulia Putintseva in the second match on the main show court, followed by British 30th seed Kyle Edmund's opener against Spaniard Jaume Munar.

Simona Halep and Alexander Zverev are handed Court One opportunities, with Stan Wawrinka, Eastbourne winner Karolina Pliskova, Stefanos Tsitsipas and Caroline Wozniacki on Court Two.

Play starts at 11:00 local time on all courts other than Centre and Court One, where action begins two hours later.

Last year's men's runner-up, Kevin Anderson of South Africa, starts out on Court Three when he plays France's Pierre-Hugues Herbert, the man who will partner Andy Murray in doubles later in the week.

Heather Watson, Britain's only other singles player in action on Monday, gets proceedings going on Court 12 when she plays 17-year-old American Caty McNally.

McNally has lost in each of the last three Wimbledon girls' doubles finals but won the 2018 US Open junior title in tandem with Gauff.

"I think it's better for me now to be lower-ranked," Naomi Osaka told reporters at the All England Club this weekend.

Two-time grand slam champion Osaka is set for a long career at the top, yet she did not appear to enjoy her first stint as world number one.

The Japanese was overshadowed even as she made her major breakthrough at the US Open last year, her achievement secondary to an extraordinary outburst from her final opponent and idol Serena Williams.

Osaka triumphed again at the Australian Open in January, though, to become the WTA Tour's top-ranked player with just her third senior title.

But eight tournaments and eight disappointing early exits later, the 21-year-old enters Wimbledon at number two and, seemingly, much happier for it.

"Mentally, it was way more stress and pressure than I could have imagined," she said. "I don't think there was anything that could have prepared me for that, especially since I'm kind of an overthinker."

Ashleigh Barty now has that pressure and Osaka prefers the position of challenger in London, even if she is determined to wrestle back the number one spot.

"If you win the tournament, you're automatically number one," she added. "That, for sure, is a really big goal of mine. I don't have to think about defending the ranking or anything."

Next time - perhaps in just two weeks - Osaka might be prepared to defend top spot. As we examine, the first attempt represented a steep learning curve.

 

DUBAI TENNIS CHAMPIONSHIPS (LOST R2 VS KRISTINA MLADENOVIC)

Osaka split with coach Sascha Bajin after her Australian Open success and then endured a miserable start to her reign as number one. "This was just one match," she said after losing to Mladenovic. "Even if I don't win any matches for the rest of the year, I wouldn't say I'm concerned."

INDIAN WELLS OPEN (LOST R4 V BELINDA BENCIC)

Returning to the scene of her first WTA title, Osaka recovered some form at Indian Wells with new coach Jermaine Jenkins but was then thrashed by Bencic. The top seed insisted: "I tried my best and I don't really have any regrets."

MIAMI OPEN (LOST R3 V HSIEH SU-WEI)

A rollercoaster third-round match between Osaka and Hsieh, who had faced off in Melbourne, this time went the way of the underdog on another tough day for the number one.

STUTTGART OPEN (WITHDREW SF)

An abdominal injury kept Osaka from playing her semi-final, but she offered a staunch defence of her form following a last-eight fightback against Donna Vekic. "I don't understand why people are saying I'm having a bad season if I won the Australian Open," she said. "I would be lying if I said it wasn't bothering me."

MADRID OPEN (LOST QF V BELINDA BENCIC)

A second defeat of the season at the hands of Bencic came despite the struggling Osaka taking the first set and serving for the match in the third.

INTERNAZIONALI D'ITALIA (WITHDREW QF)

The Japanese ensured she would be top seed at the French Open with a run to the last eight in Rome, but her preparations for the grand slam were then hampered as she withdrew with a hand injury.

FRENCH OPEN (LOST R3 V KATERINA SINIAKOVA)

Osaka's hopes of a third straight major triumph were ended in an error-strewn 6-4 6-2 reverse. "I just feel like there has been a weight on me," she said. "I think me losing is probably the best thing that could have happened."

BIRMINGHAM CLASSIC (LOST R2 V YULIA PUTINTSEVA)

Under pressure from Roland Garros champion Barty in her final tournament before Wimbledon, Osaka crashed out in straight sets to Putintseva and lost her top ranking.

Ashleigh Barty insists her arm is "feeling good" ahead of Wimbledon after pulling out of the Nature Valley International.

The new world number one tasted Grand Slam success for the first time at the French Open and followed that up with another tournament success at the Birmingham Classic.

Barty then withdrew from her final event before Wimbledon in Eastbourne as she managed a bone stress injury in her right arm, but has been back on the practice court since Thursday.

"Yeah, it [my arm] has been good," Barty, who faces China's Zheng Saisai in the first round, told reporters.

"It's been a really good couple of days. It was nice to stay off the court for a few days, started hitting again on Thursday.

"As far as we're going, everything has kind of worked out well with monitoring our loads, all those kind of things. So feeling good.

"It's a little bit bizarre coming into Wimbledon having only played one grass court tournament. 

"We feel like we've been striking the ball really well, we're comfortable with the grass under our feet. 

"Now it's about coming out this week and try to continue do all the little things right, so come my first-round match I can play as best as I can. Regardless of a win or a loss, it's about trying to go about it the right way beforehand and then enjoying the match."

Barty, 23, goes into Wimbledon as favourite but does not see herself that way as she adjusts to life at the top of the WTA rankings.

She said: "I don't know if I'm the favourite for Wimbledon. I think I need to try and get through this first round first and foremost. 

"Obviously the process, what we've been going through, has been working. There's no need for me to change that. I've enjoyed every single minute of that. There have been some really tough times and some incredible times.

"We celebrated after the French Open. We celebrated after Birmingham. Nothing really gets out of hand. But it's important to celebrate the accolades and the milestones you do reach."

On being number one in the world, Barty added: "It's new feeling for me. Something that I've never experienced before. 

"We're still trying to go about all of our business, all of our preparations the same way. We know what we've been doing has been working. For us, it's about trying to keep that normality as much as possible.

"There's more attention, there's more of that outside noise. But from what we're trying to do on the court, it hasn't really changed much."
