Rafael Nadal says it has been "an honour and a privilege" competing with Roger Federer after the 20-time grand slam winner announced his retirement on Thursday.

In a statement posted on social media, Federer confirmed his "bittersweet decision" to call time on his top-level tennis career after next week's Laver Cup in London.

Federer won 20 grand slam titles across a legendary 24-year career, a trophy tally in majors that only Novak Djokovic (21) and Nadal (22) can better.

The 41-year-old has not competed since Wimbledon 2021, after which he underwent a third knee operation, but Nadal had hoped his fellow great would never retire.

"Dear Roger, my friend and rival. I wish this day would have never come. It's a sad day for me personally and for sports around the world," Nadal posted on his Twitter account.

"It's been a pleasure but also an honour and privilege to share all these years with you, living so many amazing moments on and off the court."

Nadal, who will team up with Federer and Djokovic as part of Team Europe's all-star cast at the Laver Cup, added: "We will have many more moments to share together.

"There are still lots of things to do together, we know that. For now, I truly wish you all the happiness with your wife, Mirka, your kids, your family and enjoy what's ahead of you."

Federer has spent 750 weeks in the top 10 of the men's singles rankings, an undefeated number for a male player since they were first published in 1973.

The Swiss has also won more men's singles main draw matches in grand slam tournaments than any other player in the Open Era (369).

As he brings down the curtain on his remarkable career, several other players paid their respects to one of the sport's all-time greats. 

"Some of Fed’s numbers are laughably impossible to top (23 straight slam semi-finals, for instance)," John Isner posted on Twitter. 

"But his impact on tennis far exceeds what he accomplished on court. Thanks for everything, RF."

Seven-time grand slam winner Petra Kvitova added: "Roger, you have always been such a huge inspiration to me. Your elegance, your grace, your beautiful game. 

"I have always held you in the highest regard and want to congratulate you for an amazing career. Tennis won’t be the same without you! Thank you."

Roger Federer's retirement from tennis marks the end of an era, as one of the sport's finest bows out next week at the Laver Cup.

A 20-time grand slam champion and six-time ATP Tour Finals victor – the latter still an undefeated record in the Open Era – the Swiss star has been one of the leading lights in the men's game.

Coming on the heels of Serena Williams' apparent finish at the summit of the sport at this month's US Open, it represents the latest major changing of the guard near the summit of tennis' upper echelons.

Throughout his career, the 41-year-old has stood either alone or alongside a rarefied group in the record group, and Stats Perform has rounded up some of his most impressive statistics.

750 - Federer has spent 750 weeks in the top 10 of the men's singles rankings, an undefeated number for a male player since they were first published in 1973.

369 - He has won more men's singles main draw matches in grand slam tournaments than any other player in the Open Era (369).

237 - With 237 consecutive weeks at number one, Federer holds the record for the longest such streak in men's singles history – a stretch of four-and-a-half years.

105 - Federer has played 105 matches at Wimbledon in the Open Era, more than any other male player.

103 - The number of ATP-level titles won by Federer in the Open Era is 103, a feat bettered only by Jimmy Connors (109).

36 - At the age of 36 years, five months and seven days, Federer won his last grand slam, at the 2018 Australian Open, becoming the oldest man to do so in the Open Era save for Ken Rosewall in 1972 (37 years, a month and 24 days, also in Melbourne).

224 - Federer has recorded 224 victories against top-10 opponents. Only Novak Djokovic (232) has more such wins in the Open Era.

15 - In his home tournament in Basel, Federer reached 15 finals, the highest tally for a player in a single ATP-level tournament since the majors turned professional in 1968.

1 - With 429 grand slam matches to his name in the Open Era, Federer is the only male player to have exceeded the 400+ mark.

10 - Federer is the only male player able to reach 10 consecutive Grand Slam finals in the Open Era (between Wimbledon 2005 and the US Open 2007).

0 - According to ATP Media info, Federer never retired from a match in his career (1,526 matches in singles, 223 in doubles).

Billie Jean King has described Roger Federer as a "champion's champion" after the Swiss maestro announced his retirement from tennis.

Having not played competitively since Wimbledon 2021, Federer revealed on Thursday he had taken the "bittersweet decision" to retire.

After being beset by injuries in recent years, Federer declared: "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."

Federer will make a farewell appearance at the Laver Cup in London next week, partnering with fellow greats Rafael Nadal and Novak Djokovic for Team Europe.

The 41-year-old will end his career with 20 grand slam singles titles, a tally only bettered by Nadal (22) and Djokovic (21) in the men's game, but King believes he was the most complete player of the modern era.

"Roger Federer is a champion's champion," King, herself the winner of eight Open-era major singles titles, wrote on Twitter.

"He has the most complete game of his generation and captured the hearts of sports fans around the world with an amazing quickness on the court and a powerful tennis mind. 

"He has had a historic career with memories that will live on and on.

"Congratulations @rogerfederer, we wish you the very best as your journey continues."

Lots of eras have ended in 2022.

Tennis has now seen two in a short period of time, as Serena Williams' decision to step away from the court after the US Open was followed by Roger Federer announcing on Thursday that he will do the same after next week's Laver Cup in London.

Federer has had one of the most decorated careers an athlete could hope for, winning 20 grand slams, including eight men's singles titles at Wimbledon.

No player has claimed more than his 369 match wins at grand slams, with Novak Djokovic second on 334.

Following the Swiss star's announcement, Stats Perform has taken a look at five key moments from a truly remarkable career.

Taking of the torch

It felt like a big moment at the time, but with hindsight it was more like something from a Hollywood movie.

Pete Sampras had dominated at Wimbledon from 1993 to 2000, winning the men's singles title seven times in eight years.

Then, in the fourth round at SW19 in 2001, a pony-tailed teenager from Switzerland rocked up and beat him.

Federer had won the boys' championship at Wimbledon in 1998, but here he became a man, beating Sampras in a five-set thriller, to the delight of the crowd.

It denied Sampras an eighth title, which would ironically be a feat achieved by Federer years later.

First grand slam win

It was, of course, Wimbledon where Federer lifted his first grand slam. Two years after his win against Sampras it was time for him to fulfil his potential, and he did just that in 2003.

Going into the tournament as number four seed, he defeated the likes of Mardy Fish, Feliciano Lopez, Sjeng Schalken and Andy Roddick to reach the final.

There, he met big-serving Australian, Mark Philippoussis, and won 7-6 (7-5) 6-2 7-6 (7-3).

People said it could be the first of many, which was somewhat of an understatement.

Five alive at Flushing Meadows

Having already mastered Wimbledon by winning it five years in a row between 2003 and 2007, Federer wanted to dominate other grand slams, which he certainly did in the United States.

After winning his first US Open title in 2004, he went on to win it again and again, culminating in repeating his Wimbledon trick by making it five consecutive in 2008.

Having earned passage to the championship match with a hard-fought four-set victory against Djokovic in the semis, Federer ended up easing to a win in the final against Andy Murray, beating the Scot 6-2 7-5 6-2 to secure number five on the hard courts of New York.

A clay clean sweep

Federer had more than proven himself on grass and hard court, but while he still won the vast majority of his matches on clay, he struggled to get over the line in the same way, particularly thanks to the presence of a certain talented Spaniard.

Rafael Nadal beat him in three consecutive French Open finals from 2006 to 2008, with Federer unable to even force a fifth set in any of those defeats.

However, in 2009 he did not have to face Nadal in the final. Instead, he came up against the man who had shocked Nadal in the fourth round, Robin Soderling.

Federer found the Swede an easier proposition in the final, beating him 6-1 7-6 (7-1) 6-4 to win his first title at Roland Garros, and complete his set of grand slams, having also won three times at the Australian Open by that point (2004, 2006 and 2007).

The final trophy lift

In what turned out to be his last grand slam success, Federer absolutely cruised through the field at the Australian Open in 2018, not dropping a set until the final.

While he had continued to go far in tournaments and wowed the crowds with his trademark rallies and forehand winners, Federer had only won three grand slams since 2010.

Federer had won the Australian Open and Wimbledon in 2017, and many thought that might have been his one last hurrah, but he arguably saved an even better showing for the first tournament of the following year.

He was made to earn it in the final, before ultimately overcoming Marin Cilic 6-2 6-7 (5-7) 6-3 3-6 6-1.

It brought his overall total of grand slam victories to 20, and though that has since been passed by Nadal (22) and Djokovic (21), Federer will go down as one of the all-time greats.

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."

Frances Tiafoe has replaced John Isner in the Team World line-up for next week's Laver Cup in London.

Isner has failed to recover from the wrist injury that forced him to withdraw from the US Open ahead of his second-round match against Holger Rune.

Fellow American Tiafoe knocked out Rafael Nadal en route to reaching the semi-finals at Flushing Meadows, where he was beaten by tournament winner Carlos Alcaraz.

The 24-year-old, now at a career high of 19th in the ATP rankings, will take Isner's place at the O2 Arena as Team World aim to end Team Europe's run of four triumphs in a row.

Tiafoe previously took part in the tournament in 2017 and 2018, but has missed the past two editions.

Team World captain John McEnroe said: "I am thrilled to have Frances on the team. 

"He's raised his game to a whole new level and has shown he can compete and win against the best players on Tour. He brings a positive energy that should help the entire team."

Tiafoe joins Felix Auger-Aliassime, Taylor Fritz, Diego Schwartzman, Alex de Minaur and Jack Sock on McEnroe's six-man team.

Team Europe, led by Bjorn Borg, is made up of Nadal, Novak Djokovic, Stefanos Tsitsipas, Casper Ruud, Roger Federer and Andy Murray.

The tournament is contested on an indoor hard court and runs for three days from September 23.

Victory at Flushing Meadows on Sunday night saw Carlos Alcaraz anointed both the US Open champion and the new world number one.

The victor of the New York final between Alcaraz and Casper Ruud would climb to the top of the ATP rankings, and a four-set success for the 19-year-old made him the youngest ever men's number one.

That record had previously belonged to a 20-year-old Lleyton Hewitt in November 2000.

Although Alcaraz's huge potential has long been public knowledge, the chances of him beating Hewitt's mark still seemed remote when he started 2022 ranked 32nd.

Even Juan Carlos Ferrero, the Spaniard's coach, did not anticipate a major breakthrough this soon, telling reporters after Sunday's win: "Of course, it comes very fast.

"It's a surprise for everybody except maybe to me, because I trained with him every day and I know [how] he's able to play on the court, [but] I was pretty sure that maybe it wasn't this year; it could be the next one."

By the time he took to Arthur Ashe Stadium against Ruud, however, Alcaraz's ascent to the top of the sport was a surprise to nobody.

Moving from number four to first place might have tied the biggest leap to number one in rankings history, but Alcaraz leads the ATP Tour in both match wins (51) and titles (five) in 2022.

There is little prospect of him slowing now, having become the first man in the Open Era to win the US Open title as early as in his second entry; the last to do so in any era was Pancho Gonzales back in 1948.

"Of course, I'm hungry for more," Alcaraz said afterwards. "I want to be in the top for many, many weeks. Hopefully many years.

"I'm going to work hard again after this week, this amazing two weeks. I'm going to fight to have more of this."

And Alcaraz will have to fight – Ferrero knows as much as that.

"The players now are going to play very motivated against him," the teenager's coach added. "Now he's number one. Before he was two or three.

"Even like this, it's like Real Madrid-Barcelona, there's a rivalry that gets you [to] increase your level. It's what is going to happen to him against his opponents. He has to be ready."

Since Roger Federer became the 23rd different men's number one in February 2004, the rankings have been dominated by the 'Big Three', with only Andy Murray and then, this year, Daniil Medvedev also leading the Tour in that time.

Now, as the 28th number one, Alcaraz – compared by Ruud to each of Federer, Rafael Nadal and Novak Djokovic – can set about securing his own long stay at the summit.

Carlos Alcaraz has a mixture of the qualities Rafael Nadal and Novak Djokovic possess, according to the man he defeated in the men's US Open final Casper Ruud.

Prodigious Spanish talent Alcaraz became a grand slam champion for the first time at the age of just 19 thanks to a 6-4 2-6 7-6 (7-1) 6-3 triumph at Arthur Ashe Stadium on Sunday.

It was a win that propelled him to the top of the world rankings for the first time, while Ruud has now lost two slam finals this year having been defeated by Nadal at the French Open.

Ruud was philosophical about losing to a player many believe will be the dominant force in the men's game, likening his movement on the court to legends Nadal and Djokovic.

"When someone asks about a player's biggest weapon you tend to think forehand, backhand, serve, whatever it is," Ruud said.

"But sort of his movement is one of his many weapons. It makes us other players feel like you need to paint the lines sort of to be able to hit a winner. Sometimes even that's not enough.

"He's very fast. He's very quick. He's a great mover. He can get to balls that we've probably never seen before.

"But you have other great movers, as well. I mean, this game has become so physically demanding, and all the players in the top of the world, they do the right things to improve always.

"Speed, agility of the players I think are just improving, improving. The physical aspect has been not changed but it has improved by everyone.

"I think Novak and Rafa and also [Roger] Federer, I think they kind of set the bar on how well you can move out there. 

"Rafa, when he was Carlos' age, he was also similar. He tracked down everything. Almost no one could hit a winner on him. Novak the same with his flexibility. He gets to certain shots that you think, 'how is that even possible?'

"Carlos has sort of a mixture of both. He's fast, flexible. He can slide around. It's impressive. He's a hard nut to crack."

Ruud can take consolation from the fact his second appearance at a slam final was a marked improvement on Roland Garros where Nadal breezed to a 6-3 6-3 6-0 triumph.

The Norwegian conceded he had more belief going up against Alcaraz in New York, though he – somewhat tongue-in-cheek – added he hopes not to play a Spaniard in any future slam finals.

"I think obviously if you reach a grand slam final, whoever you play will be a great player on the opposite side of the net," he added.

"At Roland Garros, it was hard for me to believe that I could beat Rafa. Today was not easier, but I believed it more. I think these two tournaments have sort of made my self-belief to win a grand slam grow.

"Hopefully these two experiences can help me. I guess I hope I don't play a Spanish player if I ever reach another slam final! They know what they're doing in the slam finals. Let's hope for another than a Spanish [player]."

Ruud added: "I still thought I was the underdog in a way because of Carlos, he's on paper higher ranking and all these things. 

"But it was more fun for me today. I didn't need to play the biggest idol of my life on the biggest match of my life. It was sort of easier for me to believe that I could win."

Carlos Alcaraz never thought his success would come as quickly as it has, with the 19-year-old becoming the youngest men's world number one in history by defeating Casper Ruud in the US Open final on Sunday.

It was Alcaraz's first grand slam final, and in the process he broke the record for the most cumulative court time at a single grand slam after grinding through three consecutive five-set matches in the lead-up to the four-set final.

This is the third big tournament the Spaniard has won this year. He became the first player born after the year 2000 to win an ATP 1000 Masters event when he beat Ruud at the Miami Open, and then followed it up with a straight-sets win over Alexander Zverev in the Madrid Open final.

Speaking to the media after his maiden major title, Alcaraz called it "crazy" and a "dream".

"Well, it's crazy for me," he said. "I never thought that I was going to achieve something like that at 19 years old – everything has come so fast.

"For me it's unbelievable. It's something I've dreamed since I was a kid, since I started playing tennis. Of course, lifting this trophy today is amazing for me.

"Right now I'm enjoying the moment – I'm enjoying having the trophy in my hands – but, of course, I'm hungry for more. 

"I want to be at the top for many, many weeks – hopefully many years. I'm going to work hard again after this… I'm going to fight for more of this."

With his rapid rise to the pinnacle of the sport, Alcaraz said his victory in Miami was when he realised the path he was on could include grand slam titles.

"Honestly, since I won Miami," he said. "Since I won Miami, I thought I was able to have a grand slam in my hands.

"But before Miami, I was thinking that I have to still grow up. I thought that I'm able to have good results in a grand slam, but not a champion.

"But I would say after Miami – I won great matches in a row – I would say after that I thought that I'm able to win a grand slam."

Casper Ruud was understandably disappointed to miss out on the US Open title and the world number one spot, but he vowed to continue his pursuit of a major breakthrough.

Ruud played his second grand slam final of the season at Flushing Meadows on Sunday, yet that match ended in the same manner as his French Open defeat to Rafael Nadal.

The Norwegian, who would have led the rankings had he taken the title, went down 6-4 2-6 7-6 (7-1) 6-3 to Carlos Alcaraz, who instead himself became the youngest ever number one.

It was the first major final played between two men looking to become number one for the first time.

Ruud was bidding to make the biggest leap to the top of the rankings, having previously been the world number seven.

It was not to be, but the 23-year-old's reward for his form in New York was number two – a fine consolation prize.

"It's tough to explain everything," Ruud said, reflecting on his season. "Things have been going so well. I'm so excited for it.

"Today was a special evening. Both Carlos and I knew what we were playing for, we knew what was at stake.

"It's fun that both finalists would be number two and number one tomorrow. I think it's fitting.

"I'm disappointed, of course, that I'm not number one, but number two is not too bad either. I will continue to chase for my first grand slam and the number one ranking."

Carlos Alcaraz was determined fatigue would not get the better of his US Open title tilt, but he accepted he was "a little bit" tired after defeating Casper Ruud in Sunday's final.

Alcaraz set a grand slam record for the most time spent on court at a single tournament, in large part due to playing five-set matches in the fourth round, quarter-finals and semi-finals.

Still, the 19-year-old had enough energy left to take down Ruud in four sets, with his 6-4 2-6 7-6 (7-1) 6-3 victory making him a first-time major champion and the new world number one.

Asked if he would now acknowledge the effects of this run on him, Alcaraz replied: "A little bit.

"I always say it's not time to be tired in the final round of a grand slam or any tournament; you have to give everything on court, everything you have inside. It's something I work really, really hard on."

Alcaraz is the youngest player to ever sit atop the men's rankings, and he added: "This is something I dreamt of since I was a kid, to be number one in the world, to be a champion of a grand slam.

"It's something I worked really, really hard for. It's tough to talk right now. There's a lot of emotions right now.

"This is something I tried to achieve. All the hard work I did with my team, my family... I'm just 19 years old, so all the tough decisions are with my parents, my team as well. This is something that is really, really special for me."

Carlos Alcaraz defeated Casper Ruud in four sets to win his first major at the US Open and make history in moving to the top of the ATP rankings.

Either Alcaraz or Ruud would have taken the world number one spot had they won at Flushing Meadows, and it was the 19-year-old who prevailed 6-4 2-6 7-6 (7-1) 6-3 on Sunday.

The teenager – the second-youngest New York champion of the Open Era after Pete Sampras – therefore became the youngest ever men's number one.

Alcaraz had come through five-set matches in each of the prior three rounds, and he was again worked hard by Ruud – the new number two.

Ultimately, though, the highly talented Spaniard had the staying power to win his first grand slam title, becoming the first teenager to do so since Rafael Nadal at the 2005 French Open.

Despite the draining efforts of previous nights, Alcaraz made a rapid start, quickly forging three break points in the third game of the match and taking the second of them.

Ruud did little else wrong in the first set but had to bide his time to respond, losing the opener and fending off an opportunity for a break in the second before immediately applying pressure going the other way.

The Norwegian reached an Alcaraz drop shot and lobbed his opponent before watching the backhand reply land long to lead, although three unforced errors in the next game almost let Alcaraz back in.

Instead, Ruud dug in and then profited when a sloppy Alcaraz service game allowed him to clinch the second set.

Alcaraz responded in sublime fashion, immediately piling on the pressure in the third frame and breaking down Ruud's defence with a pinpoint drop shot, yet the set was level again when he crashed into the net, with a sensational rally required to reach a tie-break.

A couple of wild Ruud strokes decided the 73-minute set in Alcaraz's favour, though, and the fifth seed went long in the fourth to set his opponent on course, with an emotional victory secured in ruthless style.

Data Slam: Marathon man Carlos crowned in New York

Only the third player to reach the US Open final after winning in five sets in each of the prior three rounds, Alcaraz avoided seeing another match going all the way – even if past results suggest that would have worked in his favour.

Regardless, Alcaraz set a new record for the most time spent on court at a major tournament. Since 1999, when this data was first available, Kevin Anderson's 2018 Wimbledon run had previously represented the benchmark.
