US Open champions past and present Andy Roddick and Carlos Alcaraz led a swathe of social media tributes to Roger Federer after the 20-time grand slam winner announced his retirement.

Federer, who has not played competitively since exiting Wimbledon at the quarter-final stage last year, revealed on Thursday that next week's Laver Cup will be his farewell tournament.

Federer appeared at a parade of former champions at Wimbledon earlier this year and hinted at his desire to feature at the All England Club once more, but his upcoming outing in London will now represent the swansong to his stunning career.

The Swiss great will become the first of the ATP Tour's 'Big Three' to exit the sport, with Rafael Nadal and Novak Djokovic still active. 

While Nadal and Djokovic have each surpassed Federer's tally of 20 major titles this year, the 41-year-old overtook Pete Sampras' previous record of 14 grand slam titles by beating Roddick in the 2009 Wimbledon final.

Roddick was among the first to pay tribute to Federer's achievements on Thursday, writing on Twitter: "Cheers Roger. Thanks for the shared memories my friend. 

"It was an honour to share time/experiences on the most hallowed grounds in our sport. Don't be a stranger."

Alcaraz, who clinched his first grand slam title and became world number one with a US Open final win over Casper Ruud on Sunday, simply wrote: "Roger…", accompanied by a heartbroken emoji.

Milos Raonic has seen his efforts to win a major title foiled by the presence of the 'Big Four' – with Andy Murray beating him on his sole grand slam final appearance at Wimbledon in 2016 – but he also showed his appreciation for Federer's impact.

"Thank you for doing more for tennis than any single individual," Raonic wrote. "Thanks to you competitors and fans across the world get to experience and enjoy it all over the world. 

"Congratulations on your achievements and the people you continue to impact in and away from tennis."

Juan Martin del Potro, who prevented Federer from winning six consecutive US Open titles with a five-set success in the 2009 final, labelled the 41-year-old irreplaceable, declaring: "I LOVE YOU, Roger. 

"Thank you for everything you've done in tennis and with myself. [The] tennis world will never be the same without you."

Former player-turned presenter James Blake added: "Roger, there was and never will be anyone like you. You crushed me on the court, but were so nice and genuine that I couldn't hate you for it. 

"You made the game better on and off the court and you will be missed. Good luck, you have earned all the success and joy in the world."

Garbine Muguruza tweeted: "RF" followed by a heartbroken emoji.

Those who shared a court with Federer were not the only ones to pay tribute, however.

A tweet from Wimbledon's official account read: "Roger, where do we begin? It's been a privilege to witness your journey and see you become a champion in every sense of the word. We will so miss the sight of you gracing our courts, but all we can say for now is thank you, for the memories and joy you have given to so many."

Roland Garros' official account tweeted: "An inspiration on and off the court. Thank you, Roger."

The US Open's handle simply posted: "Thank you, Roger."

Roger Federer has announced his retirement from tennis, declaring next week's Laver Cup in London will be his farewell tournament.

The Swiss great, who has won 20 grand slams, becomes the first of the 'Big Three' on the men's tour to call it a day, with Rafael Nadal and Novak Djokovic still active.

Federer said he was making a "bittersweet decision", having battled knee injuries in the hope of returning to the tour.

Now 41 years old, Federer wrote in a statement on social media on Thursday: "As many of you know, the past three years have presented me with challenges in the form of injuries and surgeries.

"I've worked hard to return to full competitive form. But I also know my body's capacities and limits, and its message to me lately has been clear.

"I have played more than 1,500 matches over 24 years. Tennis has treated me more generously than I ever would have dreamt, and now I must recognise when it is time to end my competitive career.

"The Laver Cup next week in London will be my final ATP event. I will play more tennis in the future, of course, but just not in grand slams or on the tour."

The Swiss great, who won eight men's singles Wimbledon titles, said he would "miss everything the tour has given me".

He returned to Wimbledon this year for a parade of champions, and said at the time he hoped to play there again, but in a competitive sense that will not happen.

Federer said there was "so much to celebrate", adding: "I consider myself one of the most fortunate people on Earth. I was given a special talent to play tennis, and I did it at a level that I never imagined, for much longer than I ever thought possible."

A player whose skills could take the breath away, Federer might trail Nadal by two and Djokovic by one on the all-time list of men's grand slam winners, but to many he will be remembered as the greatest of the trio.

Federer was a virtuoso with racket in hand, going past the previous record of men's grand slam singles wins held by Pete Sampras when landing his 15th major after an epic victory over Andy Roddick in the 2009 Wimbledon final.

He thanked his family and his support team in his announcement on Thursday, and hailed the fans who have always had his back.

Last year, Federer won the ATP's Fans' Favourite award for a 19th successive season.

He said: "You will never know how much strength and belief you have given me. The inspiring feeling of walking into full stadiums and arenas has been one of the huge thrills in my life. Without you, those successes would have felt lonely, rather than filled with joy and energy."

Federer has a financial stake in the Laver Cup, and earmarked it earlier this year as one of two comeback events, along with his home Swiss Indoors event in Basel next month.

However, now the hopes of playing that Basel event look to have been dashed.

His retirement decision comes in the wake of Serena Williams announcing last month she would be "evolving away from tennis".

Although she has tenuously left the door open for a change of heart, Williams' announcement was also effectively one of retirement too, and she was given a rousing send-off at the US Open.

Federer, whose career ran in close tandem with that of Williams, described his own career as "an incredible adventure".

"While it sometimes feels like it went by in 24 hours, it has also been so deep and so magical that it seems as if I've already lived a full lifetime," he added.

"I have had the immense fortune to play in front of you in over 40 different countries. I have laughed and cried, felt joy and pain, and most of all I have felt incredibly alive."

He recalled being "a ball kid" in Basel in his youth, and seeing players of a past generation at close quarters.

"They were like giants to me and I began to dream," Federer wrote. "My dreams led me to work harder and I started to believe in myself."

Federer had a reputation early in his career as a racket-smasher, and it was not clear that he had the temperament to maximise his talent.

That soon emerged, though, and Federer explained: "Some success brought me confidence and I was on my way to the most amazing journey that led to this day.

"So, I want to thank you all from the bottom of my heart, to everyone around the world who has helped make the dream of a young Swiss ball kid come true."

He added: "Finally, to the game of tennis, I love you and will never leave you."

With a security detail to rival that of a president, Roger Federer strode along St Mary's Walk and into Court 14, crowds on the concourses urged to clear a path for a man rarely seen in such parts of the All England Club.

This was the king among his people, out in the boondocks by his standards. With a mighty swish of his racket, he might just be able to launch a tennis ball onto Centre Court's roof from down here.

It was day two of the 2015 Wimbledon championships, a warm Tuesday morning, and Federer needed a warm-up before his opening match against Bosnian Damir Dzumhur, a player that later in the day he would trounce for the loss of just seven games. That would of course be a Centre Court assignment. Invariably all of Federer's matches get centre stage.

The tiny Court 14 seats a couple of hundred spectators, maybe a handful more at a push, and whispers had spread to mean many were occupied for what was an unadvertised practice session, a Federer guerrilla gig. The media had been given a little advance notice, and a glimpse of Federer at close quarters is hard to turn down.

There was a hefty hint Federer would be arriving when Stefan Edberg - his coach and childhood idol - showed up several minutes ahead of his charge and began to limber up, while Rob Walker of Wimbledon TV stood patiently with a camera crew and a stack of notes, ready to tell the story of the day Federer played where only mere mortals usually tread.

Suddenly more news crews appeared, a stream of day-trippers strolling past the inconspicuous court became more like a scrum, and out came the camera phones, ball boys and ball girls craning for a view, making sure of a close-up shot. A woman working for IBM grinned ear to ear. And in walked Federer, dressed head to toe in white Nike gear, carrying a couple of Wilson tennis rackets and a cap bearing his RF insignia.

A G4S security man practically bit off his bottom lip while attempting to keep a straight face and simultaneously enforce crowd control as Federer passed by him. Thou shalt not smile.

Applause rang out, fans with cheap-rate ground passes cooed at the sight of the then seven-time champion. Federer acknowledged the swelling crowd.

And for the next half-hour or so he and Edberg gently put in a light session, rallying from the baseline, these great champions going through the motions that on another day might have taken place out of public sight. It amounted to little more than a balm to the ego before lunch.

And this was just another day in the life of Roger Federer, who has now announced his retirement. He has probably forgotten all about it. Some will remember it for the rest of their lives.

Edberg takes on a real relevance in the story of Federer's retirement because they spoke together about how to go through the process.

Swedish great Edberg announced his own decision to quit in December 1995, a month before his 30th birthday, and the 1996 season became his farewell tour, feted everywhere he went.

But Edberg struggled with his form in that year of goodbyes and glad-handing, reaching only one final, losing to Boris Becker in the Queen's Club title match, and he ultimately regretted the hoopla that followed him around.

Speaking to The Tennis Podcast in 2020, Edberg explained how he warded Federer off following his example.

"We actually talked a little bit about it and I would not recommend it to anybody actually, even if it's a nice thing to do, because it does put too much pressure on yourself and there would be too many things going on in your mind," Edberg said.

"So if you're going to announce it, I would do it just before my last tournament or have it in my mind, but not for anybody else to know. It's very tough to handle, but at the same time it was a very memorable year, but I would not recommend it."

Federer only worked in tight tandem with Edberg for two years, but he has so much respect and admiration for the man that such advice was sure to have registered.

And now the 20-time grand slam winner is retiring. Let that sink in.

It will take some getting used to, tennis without Federer. Without his ritual beastings of young upstarts on tour, without his perfect manners, quasi-aristocratic foibles, and those multilingual, exquisitely delivered, post-match news conferences. Without Anna Wintour gazing down adoringly from the Royal Box. Without Mirka.

"I wanted to be a tennis player or a soccer player from a very young age," Federer said at Wimbledon some years ago.

Was there a Wimbledon final that tilted him the way of tennis?

"I think the Becker-Edberg final. I don't remember which year because they played a few times. I was sitting at home in the living room, watching them play, thinking hopefully one day I can be like them, you know," Federer said.

Edberg and Becker met in consecutive Wimbledon finals from 1988 to 1990, the Swede winning the first and last of those matches. Theirs was a great rivalry.

"That's I guess where idols and inspirations are good. They push you forward," Federer said. "Then along the way you joke around and say it's coming closer. When you win a practice match, you just fake like you've just won Wimbledon. All of a sudden it's really happening."

It was "really happening" for Federer by the late 1990s, as he won the boys' singles at Wimbledon in 1998, beating Georgia's Irakli Labadze, and barely 12 months later he was a top 100 player on the men's tour.

But he was a firebrand too as a teenager, something he was compelled to explain at Wimbledon in 2001, when the 19-year-old Federer became the centre of attention for the first time after defeating Pete Sampras, champion for the previous four years, in the fourth round.

Federer had been a picture of composure in that match and was asked whether he modelled his approach on ice-cool Pistol Pete.

"Not at all actually. I was throwing around my racket like you probably don't imagine," Federer said. "I was getting kicked out of practice sessions non-stop when I was 16. Now since maybe I think this year, I started just to relax a little bit more on court.

"I'm not smashing as many rackets as before. I realised that the racket throwing didn't help my game because I was always getting very negative."

When Federer got his hands on a grand slam trophy for the first time, it was Wimbledon in 2003 and he was lobbed a prescient question by a reporter who asked whether he might one day emulate seven-time champion Sampras at Wimbledon.

"This is one of his seven, you know. I'm so far away," he said. "I'm just happy to be on the board. If I look at all the players who have won here, a lot have been idols to me. Just to be on the board with (Bjorn) Borg and these people, it's just nice to be a part of history at Wimbledon."

Nevertheless, that was the first of five consecutive Wimbledon triumphs for Federer, matching a Borg record. Around such feats are legends created; because of the vicarious pleasure he provided to so many, crowds will forever flock around Federer, whether on Centre Court, Court 14 or his local food court.

As Federer's slam stack grew, and he nudged nearer Sampras' hauls of seven Wimbledon titles and 14 majors, the American great made his Swiss successor a promise: he would be there when those records began to fall.

When Federer fended off Andy Roddick 16-14 in the fifth set of the 2009 Wimbledon final to go to 15 slams, Sampras indeed was there, albeit he arrived late.

"It was a bit special," Federer said. "When he walked in and I saw him for the first time, I did get more nervous actually. I said hello to him, too, which is unusual. But I thought, I don't want to be rude."

And in 2017, nudging 36, Federer triumphed at Wimbledon for an eighth and final time, beating an injury hampered Marin Cilic.

"Winning eight is not something you can ever aim for, in my opinion," he said afterwards. "If you do, you must have so much talent and parents and the coaches that push you from the age of three on, who think you're like a project," he said. "I was not that kid. I was just really a normal guy growing up in Basel, hoping to make a career on the tennis tour."

At the beginning of 2018, he added a sixth Australian Open title to reach 20 slam crowns, a figure beyond the wildest dream of anyone in men's tennis before the Big Three showed up.

The argument rages on about who has been the greatest men's tennis star of all-time, and whether it should be Federer, Novak Djokovic or Rafael Nadal from this era who is the prime contender for such a nebulous crown.

Federer has a losing head-to-head against both his younger rivals, there is no escaping that fact. He trails Nadal 24-16 and Djokovic 27-23. Both have been whittling away at his records, taking their fair share. Yet Federer still has the most Open Era match wins among men at Wimbledon (105) and the Australian Open (102), the most wins in slams overall by a man (369), and the most grass-court singles titles in ATP tour history (19).

He won 103 tournaments, second only to Jimmy Connors (109). He underwent knee surgery twice in 2020 and returned to seek more silverware, because he believed he could still win, even as his 40th birthday approached.

Federer is the man who recalibrated the levels that players can reach in men's tennis, the game-changing figurehead that Nadal and Djokovic have been chasing from the outset of their own magnificent careers.

Without Federer to aim for, perhaps Nadal and Djokovic would not have scaled such great heights.

Perhaps, perhaps, perhaps...

What is certain is that the Federer era is ending. And that's the thing about eras, they always end. Sometimes, you've just got to be grateful to have lived through them. Roger that?

Roger Federer has announced his retirement from tennis, declaring next week's Laver Cup in London will be his farewell tournament.

The Swiss great, who has won 20 grand slams, becomes the first of the 'Big Three' on the men's tour to call it a day, with Rafael Nadal and Novak Djokovic still active.

Federer said he was making a "bittersweet decision", having battled knee injuries in the hope of returning to the tour.

Now 41 years old, Federer wrote in a statement on social media on Thursday: "As many of you know, the past three years have presented me with challenges in the form of injuries and surgeries.

"I've worked hard to return to full competitive form. But I also know my body's capacities and limits, and its message to me lately has been clear.

"I have played more than 1,500 matches over 24 years. Tennis has treated me more generously than I ever would have dreamt, and now I must recognise when it is time to end my competitive career.

"The Laver Cup next week in London will be my final ATP event. I will play more tennis in the future, of course, but just not in grand slams or on the tour."

Serena Williams' long and illustrious tennis career looks to have drawn to a close after the American lost to Ajla Tomljanovic at the US Open on Friday. 

Following a long piece in Vogue last month, Williams wrote of her plan to "move in a different direction" after "these next few weeks", suggesting the tournament at Flushing Meadows would be her last outing.

Thanks to her success and brilliance on the court, Williams has become synonymous with tennis and is regarded by many as the greatest the women's sport has ever seen.

At the age of 40, Williams has persisted with tennis far longer than most do, and that is testament to her quality and enduring desire for success.

Though Williams left a glimmer of a chance that she may yet play again, joking that she "always did love Australia", she may well have taken to the court for the last time. Here, Stats Perform takes a look at the key facts, stats and figures of her career; in other words, Serena's remarkable legacy.

Twenty-three… and done?

Of course, the headline fact for Williams' career is her grand slam titles count.

She has won 23, which is more than anyone else in the Open era.

But she still had one target left: matching Margaret Court. The Australian's 24 grand slam successes include nine won before the Open era began in 1968, though her overall total has been the benchmark ever since she claimed her final crown at the US Open in 1975.

Clearly, victory for Williams at Flushing Meadows would have been the perfect farewell, but it was not to be. Will that near-miss encourage her to take one more shot in Court's homeland next year?

The finals hurdle

Had Williams managed to reach the championship match in Queens, she would have equalled another record.

She headed into the US Open having played in 33 grand slam finals, one more than Martina Navratilova.

But Chris Evert (34) sits out in front, and that record is now set to remain hers for many, many years.

Top of the pile

It's been a while now since Williams was last the highest-ranked player in the world, but in a way that only further highlights how remarkable her career has been.

She's spent 319 weeks ranked as world number one, which is behind only Steffi Graf (377) and Navratilova (332).

While many might have expected Williams to have been top of the pile for even longer, it's worth remembering how she's spent time out due to injuries and pregnancy, with her general involvement in top-level tennis decreasing after 2014 when she played 16 tournaments – in 2016 that halved to eight, and during no year since has she played in more.

Additionally, some will also be surprised to learn she actually only finished the year as the top-ranked female player five times. Nevertheless, that's still third to only Graf (eight) and Navratilova (seven).

Go hard or go home

Such has been Williams' quality, she was always considered a threat regardless of the surface – she's won each grand slam at least three times.

But there's no denying she was at her most lethal on hard courts.

She has won 48 WTA Tour-level titles on hard courts, which is 11 more than anyone else (Graf) in the Open era.

Those 48 come from a grand total of 73 across all surfaces, leaving her ranked fifth behind Navratilova (167), Evert (157), Graf (107) and Court (92).

Surface to say…

Williams' comfort on hard courts goes even further than that.

She's won 541 matches on the surface, making her one of just two female players to surpass 500 victories on one specific ground type.

Navratilova (600 on carpet) is the only other player to achieve the feat, with Serena's sister Venus (498 on hard) the closest to the 23-time grand slam champion.

The grass is greener

Despite that unrivalled excellence, hard courts may not be the surface many feel to be most synonymous with Williams, however.

Wimbledon is the tournament that would appear to be her favourite.

She's reached the final at SW19 11 times. Only Navratilova can better that record for the most finals at one tournament – though it's worth saying she contested the WTA Finals and Chicago 14 times each, Eastbourne 13 times and 12 at Wimbledon.

Jordan. Ali. Woods. Williams. That's it, that's the company.

Serena Williams is about to draw the curtain on one of the great sporting careers.

A brilliant black sports star excelling on a global stage, she has shifted and shaped opinions over the past 25 years.

Her life has been touched by tragedy as well as great joy, and she has just about lived to tell the tale.

As she prepares for her final US Open, Stats Perform looks back at the obstacles that have been put in front of the 23-time grand slam champion. 

Racism since her early days

After learning the game in Compton, Williams and sister Venus endured plenty of outrageous treatment before a notorious incident in 2001 at Indian Wells.

Russian Elena Dementieva reacted to a quarter-final defeat to Venus by saying the semi-final between the sisters would be determined by their father, Richard. That baseless allegation of manipulation was followed by an injured Venus withdrawing from the match against Serena shortly before its start time.

Serena met Kim Clijsters in the final, and there were grim jeers for Venus and Richard when both took their grandstand seats. They and Serena copped brutal treatment from spectators, with Richard stating he was racially abused.

Serena beat Clijsters but did not play at Indian Wells again until 2015, recalling her memories of 2001 in an article for Time, explaining it had "haunted" the family, particularly her father.

She wrote: "He dedicated his whole life to prepping us for this incredible journey, and there he had to sit and watch his daughter being taunted, sparking cold memories of his experiences growing up in the South."

Williams told Sirius XM in February 2021: "I had to make people realise that it's okay to be black and to play tennis."

Sexism never far away

Williams considered causing a scene at Wimbledon in 2011 after being sent out to the distant Court Two to play a second-round match.

It seemed a bizarre move – probably just ignorant – to put the defending women's champion anywhere but Centre or Court One, and while she was reluctant to fully vent her frustration, it was obvious enough.

Seemingly pointing a finger at those in power, Williams said: "They're not going to change."

An angry Williams accused chair umpire Carlos Ramos of sexism in a stormy 2018 US Open final, when she lost to Naomi Osaka.

Williams was warned for receiving coaching on court, which she denied, then penalised a point for racket abuse, before being docked a game after accusing Ramos of being "a thief".

"I'm here fighting for women's rights and for women's equality and for all kinds of stuff," Williams said afterwards. "For me to say 'thief' and for him to take a game, it made me feel like it was a sexist remark. He's never taken a game from a man because they said 'thief'."

Williams was fined $17,000 by tournament chiefs but backed by the WTA, which runs the women's tour outside the slams.

Perilous childbirth

In February 2018, Williams wrote an article for CNN that began with the line: "I almost died after giving birth to my daughter, Olympia."

She wrote of having had "a pretty easy pregnancy" and a routine C-section in August 2017, only for that to be followed by a pulmonary embolism and "a slew of health complications" she was "lucky to have survived", including a large hematoma in her abdomen. Her first six weeks as a mother were spent in bed.

Sister's death

It was September 2003, shortly after Williams underwent knee surgery that forced her out of the US Open, that her sister Yetunde Price was shot and killed in Compton.

Price was 31, with a local gangster sentenced to 15 years for voluntary manslaughter.

Williams addressed court after the April 2006 sentencing of Price's killer, saying she had "wanted to let you know that this was unfair to our family, and our family has always been positive and we always try to help people".

In 2018, Williams was trounced 6-1 6-0 by British player Johanna Konta at the Silicon Valley Classic. She came onto court moments after learning the man who shot her sister dead had been freed from prison, and later told Time: "I couldn't shake it out of my mind."

Walking on broken glass

It's an idiom, and an Annie Lennox song, but walking on broken glass was almost the moment that ended Williams' career.

It could have been a case of unlucky 13 for Williams in July 2010 when within days of winning her 13th grand slam title she suffered a foot injury, and later revealed it had been caused by stepping on glass while leaving a Munich restaurant.

She told USA Today: "I was standing, recovering, thinking I got a little cut and telling my nephew, who was with us, to be careful. Then my practice partner put a cellphone down to the floor so we could see, and there was a huge puddle of blood. I said, 'OMG, I don't think this is good'."

She needed both feet stitching up and underwent surgery to fix a drooping big toe, missing almost a full year on tour. Early in 2011 she underwent treatment for a pulmonary embolism and blood clot in her lungs, after checks were carried out during her recovery.

Chasing Court

Margaret Court has been the figure Williams has chased but looks destined to fall short of, with the Australian set to remain tantalisingly out of reach.

Four final losses for Williams since landing her 23rd major have been increasingly agonising, and it has been clear that her primary motivation for playing on all this time has been to surpass Court.

Court's controversial views on the LGBTQ community have upset many in tennis. Williams, however, just wanted to finish top of the pile, regardless of who was presently leading the way in the grand slam race.

Barring a sporting near-miracle over the US Open fortnight, she will remain second in that race, albeit the grand slam leader in the Open Era – winner of the most titles since the majors embraced professionalism in 1968.

Serena Williams' long and illustrious tennis career is drawing to a close after the American confirmed on Tuesday that the countdown has begun.

Following a long piece in Vogue, Williams wrote of her plan to "move in a different direction" after "these next few weeks", suggesting the US Open – which begins in late August – will be her last outing.

Thanks to her success and brilliance on the court, Williams has become synonymous with tennis and is regarded by many as the greatest the women's sport has ever seen.

Yet, her seemingly imminent retirement cannot be seen as a shock. At the age of 40, Williams has persisted with tennis far longer than most do, and that is testament to her quality and enduring desire for success.

With Williams now reaching the end, Stats Perform takes a look at the key facts, stats and figures of her career; in other words, Serena's remarkable legacy.

Twenty-three… and counting?

Of course, the headline fact for Williams' career is her grand slam titles count.

She has won 23, which is more than anyone else in the Open era.

But she's still got one target left: matching Margaret Court. The Australian's 24 grand slam successes include nine won before the Open era began in 1968, though her overall total has been the benchmark ever since she claimed her final crown at the US Open in 1975.

Clearly, victory for Williams at Flushing Meadows would be the perfect farewell.

The finals hurdle

Even if Williams only reaches the championship match next month, she'll still be equalling a different record.

Assuming she does compete in Queens, Williams heads into the US Open having played in 33 grand slam finals, one more than Martina Navratilova.

But Chris Evert (34) sits out in front, and that record will remain hers for many, many years if Williams cannot reach the finale at Flushing Meadows.

Top of the pile

It's been a while now since Williams was last the highest-ranked player in the world, but in a way that only further highlights how remarkable her career has been.

She's spent 319 weeks ranked as world number one, which is behind only Steffi Graf (377) and Navratilova (332).

While many might have expected Williams to have been top of the pile for even longer, it's worth remembering how she's spent time out due to injuries and pregnancy, with her general involvement in top-level tennis decreasing after 2014 when she played 16 tournaments – in 2016 that halved to eight, and during no year since has she played in more.

Additionally, some will also be surprised to learn she actually only finished the year as the top-ranked female player five times. Nevertheless, that's still third to only Graf (eight) and Navratilova (seven).

Go hard or go home

Such has been Williams' quality, she was always considered a threat regardless of the surface – she's won each grand slam at least three times.

But there's no denying she was at her most lethal on hard courts.

She has won 48 WTA Tour-level titles on hard courts, which is 11 more than anyone else (Graf) in the Open era.

Those 48 come from a grand total of 73 across all surfaces, leaving her ranked fifth behind Navratilova (167), Evert (157), Graf (107) and Court (92).

Surface to say…

Williams' comfort on hard courts goes even further than that.

She's won 539 matches on the surface, making her one of just two female players to surpass 500 victories on one specific ground type.

Navratilova (600 on carpet) is the only other player to achieve the feat, with Serena's sister Venus (498 on hard) the closest to the 23-time grand slam champion.

The grass is greener

Despite that unrivalled excellence, hard courts may not be the surface many feel to be most synonymous with Williams, however.

Wimbledon is the tournament that would appear to be her favourite.

She's reached the final at SW19 11 times. Only Navratilova can better that record for the most finals at one tournament – though it's worth saying she contested the WTA Finals and Chicago 14 times each, Eastbourne 13 times and 12 at Wimbledon.

Alize Cornet claims several players contracted COVID-19 at last month's French Open, but kept the outbreak quiet in order to avoid mass withdrawals from the tournament.

Wimbledon has already been rocked by two high-profile male players withdrawing after testing positive for the virus, with last year's runner-up Matteo Berrettini and 2014 US Open champion Marin Cilic both pulling out ahead of scheduled first-round matches on Tuesday.

Now Cornet, who equalled Ai Sugiyama's all-time record of 62 consecutive grand slam main-draw appearances in a win over Yulia Putintseva on day two, claims there were cases at Roland Garros that did not come to light.

"At Roland Garros, there was a Covid epidemic, no one talked about it. In the locker room, everyone got it and we said nothing," she told L'Equipe.

"When it comes out in the press, with big players, it will start to set fire to the lake everywhere and that worries me a little.

"[2021 French Open winner Barbora] Krejcikova withdrew saying she had Covid, and the whole locker room was sick. 

"At some point, we all might have had the flu. The thing is, we have the symptoms, itchy throat… we play and everything is fine, it's fine. 

"At Roland, I think there have been a few cases and it's a tacit agreement between us. We are not going to self-test to get into trouble! 

"Afterwards, I saw girls wearing masks, maybe because they knew and didn't want to pass it on. You also have to have a civic spirit."

Novak Djokovic would be delighted by the prospect of facing Rafael Nadal in the Wimbledon final, as he targets revenge for his French Open loss to the Spaniard.

Nadal remains on course for a calendar Grand Slam after following up January's Australian Open victory with his 14th French Open title earlier this month, having overcome Djokovic in a quarter-final classic on the clay in Paris.

The Spaniard's Roland Garros triumph moved him two clear of Djokovic's tally of 20 grand slam titles, while his last-eight win over the Serbian was his 29th in the pair's head-to-head rivalry (Djokovic has 30 wins).

With 59 career meetings, the duo have met one another more often than any other men's pairing in the Open Era, and they could be set for a final showdown at Wimbledon after landing on opposite sides of the draw.

Speaking to Sky Sports, defending Wimbledon champion Djokovic said he would relish such a contest and insisted Nadal, who has not triumphed on the grass in London since 2010, is among the favourites to take home the title.

"If we get to face each other it means we're both in the finals, which I think we both want," Djokovic said.

"It's a very long way [away], but of course you have to put him as one of the favourites, even though he hasn't played at Wimbledon for the last three years [including the cancelled 2020 edition], I think.

"But still, he's Nadal, he has achieved what he has achieved throughout his career and also this year, of course, which gives you a lot of confidence in his case.

"I'm sure there's going to be a lot of great matches ahead for both of us, and if we get to face [each other] in the final… I'd love to face him in the final and get revenge for Paris!"

Nadal has beaten Djokovic in 11 of the duo's 18 grand slam meetings, although the Serbian holds a 2-1 advantage over their three Wimbledon contests, triumphing in the 2011 final and the 2018 semi-finals.

Djokovic begins his Wimbledon campaign by facing Kwon Soon-woo on Centre Court on Monday, with Nadal taking on Argentina's Francisco Cerundolo the following day.

Rafael Nadal's latest grand slam triumph at the French Open is "unbelievable", says Roger Federer, who believes his rival "keeps raising the bar".

The Spaniard cruised through to both a record 14th success on clay at Roland Garros and a record-extending 22nd men's grand slam title with a straight sets demolition of Casper Ruud.

That made it two from two in 2022 for the 36-year-old, leaving him clear of both Federer and Novak Djokovic, who remain on 20 grand slam crowns each.

The former – who has enjoyed a strong sporting rivalry and friendship with Nadal throughout their intertwined careers – however has nothing but praise for his latest achievement.

"I didn't watch the final," Federer told Swiss newspaper Tages-Anzeiger. "I watched the quarter-final [against Djokovic] a bit before I went to sleep.

"In general, it's just unbelievable what Rafa has achieved. The record of Pete Sampras, which I beat, was 14 grand slam titles.

"Now Rafa won the French Open 14 times. That's unbelievable. I was happy for him that he did it again.

"Hats off to Rafa. After the 10th, 11th time, I already thought: 'This can't be.' He keeps raising the bar. It's gigantic."

Federer has been unable to add to his own haul of grand slams, having missed the tail-end of 2021 and start of 2022 through injury as he continues to recover from knee surgery.

The 40-year-old Swiss star acknowledged he has not yet plotted anything more than competing in the Laver Cup and Basel Open in October, stressing he will focus on achieving full fitness rather than setting a return date.

"After Basel, the season is over anyway," he added. "It's important for me to get fit again so that I can train fully. Once I've done that, I can choose how many tournaments I play and where.

"The Laver Cup is a good start, I don't have to play five matches in six days.

"I will have be able to do that in Basel. That's why I have to prepare for it in practice. I'm curious myself what's still to come.

"But I'm hopeful, I've come a long way. I'm not far away. The next three or four months will be extremely important."

On a return to top-class tennis in 2023, Federer said that such a move remained the aim, adding: "Yes, definitely. How and where, I don't know yet. But that would be the idea. Definitely."

Alexander Zverev is determined to "come back stronger than ever" after undergoing ankle surgery on Tuesday. 

Zverev tore all three lateral ligaments in his right ankle during the second set of his French Open semi-final against Rafael Nadal last week. 

The German is set to miss Wimbledon after his hopes of winning a first grand slam at Roland Garros came to a painful end. 

Zverev is ready to knuckle down with his rehabilitation after going under the knife in his homeland. 

Along with a picture of himself in his hospital bed giving the thumbs up, he posted on Instagram: "We all have our own journey in life. This is part of mine. 

"Next week I'll reach a career-high ranking of number two in the world, but this morning I had to undergo surgery. After further examination in Germany, we received confirmation that all three of the lateral ligaments in my right ankle were torn. 

"To return to competition as quickly as possible, to ensure all the ligaments heal properly, and to reclaim full stability in my ankle, surgery was the best choice. My rehab starts now and I'll do everything to come back stronger than ever! 

"I am continuing to receive so many messages and would like to thank everyone once again for supporting me during such a difficult time." 

Nadal went on to beat Casper Ruud in the final in Paris on Sunday to claim a record-extending 14th French Open title, taking his astonishing tally of grand slam triumphs to 22. 

Rafael Nadal says it is "crazy" for people to even consider him completing the calendar Grand Slam after triumphing at the Australian Open and French Open.

The Spaniard returned from his long battle with a foot injury to claim the first major of the year in Melbourne, moving clear of Roger Federer and Novak Djokovic for the most grand slam titles in men's history.

Nadal added a record-extending 22nd major to his collection as he lifted a 14th French Open title on Sunday with a straight-sets victory over Casper Ruud.

The 36-year-old was given a couple of injections before every match and will undergo radio frequency injections in a bid to ensure he can go in search of a third major title of the year at the All England Club.

Nadal remains unsure whether he would undergo a major operation to prolong his career, but hopes to be able to be in London when Wimbledon starts on June 27.

Success on the grass courts of Wimbledon would be a third major of the year before the US Open starts at the end of August, but Nadal insists he cannot look that far ahead on his quest for all four grand slams.

"It's crazy to think about completing the Grand Slam after Australia and Roland Garros," he told

"I don't even consider it. More than winning the Grand Slam, I would sign up just to be able to play all four tournaments.

"It's crazy. To win all four, it seems crazy to me because it is something that nobody has done since Rod Laver. 

"The one who came closest was Novak last year. It's crazy to think about it."

While Nadal remains in contention for the calendar Slam, he continues to battle through a foot injury that has plagued him throughout his career.

But the prospect of retirement does not concern Nadal, who is prepared for life after tennis given the amount of times he has thought injury would curtail his playing days.

"I imagine just as I have experienced it many times in my career that I have had to be out of competition for months due to injuries," he added. 

"I have always been happy outside of tennis. It is not something that makes me lose sleep or have any fear of my life after tennis. 

"I have and have always had many things that make me happy beyond tennis."

Rafael Nadal can make it three grand slam titles out of three if his body holds up sufficiently well for Wimbledon, says Tim Henman.

After adding the French Open title to the Australian Open that he won in January, Nadal is halfway to a possible calendar grand slam of all four majors.

That was last achieved in men's singles in 1969, when Australian great Rod Laver carried off the full set.

Nadal received injections before every match at Roland Garros to effectively send his troublesome left foot to sleep and curb pain, and he will have radiofrequency treatment in a bid to ensure he can go in search of a third major title of the year at the All England Club.

The 36-year-old Spaniard hopes to be able to be in London when Wimbledon starts on June 27, and having won there in 2008 and 2010, he will believe in his chances of a third slam on grass.

Former world number four Henman told Eurosport: "If Nadal is healthy, which is a big challenge now with this foot injury, can he win Wimbledon? Absolutely. So I think that's incredibly exciting."

Nadal now has 14 French Opens among his 22 grand slams, a men's record, and is two clear of Roger Federer and Novak Djokovic who share second place on the all-time majors list.

Federer might be finished as a force at the top level, although he appears ready to give it one more shot later in the year, while Djokovic will likely start as favourite for Wimbledon glory, regardless of Nadal's recent feats.

"In terms of who's going to end up with the most grand slams, a couple of years ago I would have said Djokovic, for sure," said Henman, a perennial British favourite at Wimbledon who reached four semi-finals there. He now sits on the board of the All England Club, the tournament hosts.

"Right now, with that little bit of distance, I think Nadal has got a great chance. It's going to be fascinating to see. You've got another opportunity in three weeks' time, so fingers crossed, I so hope Nadal can be there on grass."

Rafael Nadal says he will play at Wimbledon if his body allows him to after winning a record-extending 14th French Open title on Sunday.

The legendary Spaniard has now won two more majors than Roger Federer and Novak Djokovic after taking his astonishing haul to 22 with a 6-3 6-3 6-0 defeat of Casper Ruud at Roland Garros.

Nadal's latest triumph was achieved despite the 36-year-old having anaesthetic injections on his nerves that left his foot "asleep."

The Mallorca native revealed he was barely able to walk after beating Corentin Moutet in the second round of his favourite tournament in Paris.

Nadal says he was given a couple of injections before every match and will undergo radio frequency injections in a bid to ensure he can go in search of a third major title of the year at the All England Club.

The record-breaking Nadal is not sure if he would want to undergo a major operation to prolong his career, but hopes to be able to be in London when Wimbledon starts on June 27.

He said: "I'm going to be in Wimbledon if my body is ready to be in Wimbledon. That's it. Wimbledon is not a tournament that I want to miss.

"I think nobody wants to miss Wimbledon. I love Wimbledon. I had a lot of success there. I have lived amazing emotions there. So full credit and respect to the tournament.

"A player like me, I am always ready to play Wimbledon. So if you ask me if I will be in Wimbledon, I can't give you a clear answer. If I want to win Wimbledon, of course. Let's see how the treatment works.

"I don't know. I don't want to talk about how many injections I had, because as you can imagine, I had to take a lot of anti-inflammatories too. But before every single match I had to do a couple of injections."

Nadal has ruled out putting himself through the same treatment during Wimbledon that he underwent during his latest glorious run in Paris.

He added: "Wimbledon is a priority, always has been a priority. If I am able to play with anti-inflammatories, yes; to play with anaesthetic injections, no.

"I don't want to put myself in that position again. It can happen once, but it is not a philosophy of life that I want to follow. So let's see.

"I am always a positive guy, and I am always expect the things going the right way. So let's be confident, and let's be positive. Then let's see what's going on."
