While seven of the top 12 players heading into Saturday’s third round at the U.S. Open made at least one double bogey in strong wind and cool temperatures, Rory McIlroy was not among them.

The 2011 U.S. Open champion and four-time major winner made just one birdie in his score of three-over 73 on moving day at Brookline, but his putter provided salvation late. 

He was able to keep himself within striking distance with a string of par saves, to sit three shots back from co-leaders Will Zalatoris and Matthew Fitzpatrick heading into the final round on Sunday at The Country Club.

"It was one of the toughest days on a golf course I’ve had in a long time,” McIlroy said afterwards.

"I just needed to grind it out, and I did on the back nine. To play that back nine at even par today was a really good effort, I thought. Just kept myself in the tournament. That's all I was trying to do. Just keep hanging around.

"I had some really good putts for pars coming in, 13, 15, great up-and-down on 16, good putt on 17. Then was really fortunate at the last to get that drop from the grandstand and be able to hit it on the green from there."

With only nine players under par for the tournament, blustery and overcast conditions provided palpable difficulty on Saturday.

"I know guys aren’t going to go out there and shoot the lights out," McIlroy said. "I mean, 67 from Will out there today is unbelievable. Such a good score. 68 from Fitz as well.

"I certainly thought I was going to be a few shots further back than I was at the end of the day, but Jon [Rahm] struggled there coming in.

"Even though it was such a tough day and feel like I battled well and whatever, to still only be three back going into tomorrow is a good thing for me."

Jon Rahm remains upbeat coming into the final round at U.S. Open, after a difficult Saturday saw him finish one stroke from tied leaders Will Zalatoris and Matthew Fitzpatrick.

The world number two held the outright lead approaching the 18th hole at Brookline, but a double bogey put him on one-over for the day and three-under after 54 holes.

Blustery and overcast conditions made moving day at The Country Club more about survival, and Rahm remains within contention despite his disappointing finish to the round.

"Good round of golf," he said afterwards. "It was obviously extremely difficult conditions, the wind being a little bit higher and stronger than the last few days, a different direction. Then the course being a little bit firmer, right, that's just a recipe for difficulty.

"Obviously, I think a lot of people are just thinking about 18. The truth is, 18, it was six good shots. Unfortunately, it added up to 6, but it was all good swings.

"If anything, it was maybe a choice or a decision on the fairway bunker, but swings were good, so execution was proper. So I'm happy about that in that sense."

The defending champion hit the bunker with his tee shot on the 18th and compounded that by hitting its lip and staying there, before finding another bunker with his next shot and two-putting for the double bogey.

It came after three birdies between 14 and 17 to put him on five-under, momentarily moving ahead of Zalatoris and Fitzpatrick as conditions dramatically cooled, placing further difficulty on shot and club selection.

"After I hit the shot, I realised the ball was a little bit deeper in the sand than I could really truly see," he said.

"But I think I got maybe -- tried to be a little too perfect with the shot. I had a 9-iron in hand. That's plenty to get over that lip.

"It is what it is. I think I got a little bit too cute with the shot."

Will Zalatoris and Matthew Fitzpatrick share the lead coming into the final round at the U.S. Open, finishing a tough Saturday on four-under par at Brookline.

Only nine players at this third major of the year have scores under par after 54 holes at the Country Club, and the tied lead between Zalatoris and Fitzpatrick only came after Jon Rahm's dreadful final hole in overcast and blustery conditions.

The world number two had the outright lead coming into his final hole on moving day, but three consecutive bunker shots and a two-putt led to a double-bogey on the par-four 18th and three-under after 54.

Zalatoris and Fitzpatrick have not won as professionals in the United States, with the former agonisingly finishing second at the 2021 Masters and this year's PGA Championship.

With Zalatoris finishing his round earlier in the day, Rahm finished as the conditions further cooled, placing particular difficulty on the approach to the green with club selection.

A visibly frustrated Rahm was able to compensate with some exceptional putting on the back nine, however, sinking a long birdie putt on the 14th to put him level with the two leaders. Three birdies between 14 and 17 were undone by the last hole, however.

Scottie Scheffler recovered from a double-bogey and three consecutive bogeys between 11 and 14 to finish Saturday on two-under, securing a birdie on the 17th before a massive par save on the last after hitting the bunker.

The usually stoic Scheffler did not hide his emotions with a triumphant fist-pump after the save, which left the world number one tied with Adam Hadwin and Keegan Bradley.

Joel Dahmen and Collin Morikawa fell down the leaderboard after opening Saturday with the lead on five-under. Morikawa's natural left-to-right game particularly suffered, shooting a seven-over 77.

Dahmen is joined on one-under by Sam Burns and Rory McIlroy, who only made seven greens in regulation but stayed in contention with a string of saves on the back nine.

Shot of the day

After two birdies and a bogey through his first seven holes, Scheffler really shone on the eighth.

His stunning eagle on the par-five hole saw him leap into a two-shot lead at the summit of the leaderboard.

Player of the day - Will Zalatoris

In a day characterised by survival in blustery conditions at Brookline, Will Zalatoris was one of the few on Saturday who thrived.

His ball-striking shone on an overcast day, scoring only one bogey as the rest of the field struggled to find the green.

Chipping in

Zalatoris: "Yeah, that was brutal. When I made a mistake, I made sure I was on the fat side of the green or having room where I could maybe at least chip one up there from eight to 10 feet."

Scheffler: "There's a lot of trees on this golf course, and it's gusty as well. So it's definitely unpredictable. I think that's what happens when you get these foresty golf courses, and then with the gusts, I mean, that little golf ball is just getting thrown around all over the place." 

A little birdie told me...

- Victory on Sunday would see Fitzpatrick emulate Jack Nicklaus, winning the U.S. Open at the same course he won the U.S. Amateur, after beating Oliver Goss at the Country Club in 2013.

The U.S. Open will allow players competing in the LIV Golf Invitational Series to feature this year, but that may not be the case in future.

That is the message from USGA chief executive Mike Whan, who has defended the decision to grant LIV Golf players the chance to compete at this year's U.S. Open.

Charl Schwartzel won the inaugural LIV Golf event in London last week, pocketing $4.75million, but the tournament was filled with controversy as the PGA Tour announced their punishment for the breakaway stars.

Tour commissioner Jay Monahan confirmed the 17 members who were playing in the first LIV Golf event would be banned, including Dustin Johnson, Phil Mickelson and Sergio Garcia.

Rory McIlroy and Jon Rahm have been vocal supporters of the Tour's decision, alongside Justin Thomas as the saga overshadows the U.S Open.

Bryson DeChambeau and Patrick Reed have also joined the controversial Saudi Arabia-backed breakaway, with the pair already aware of the consequences of their decision.

But the USGA announced those featuring in the LIV Golf tournament at the Centurion Club would still be able to play at The Country Club in Brookline for the third major of the season.

Whan was quick to explain the USGA's decision as the U.S. Open prepares to start on Thursday.

"We [the USGA] definitely feel responsibility to this game, and we feel a responsibility to the competitors that play it. We did sit down and have a long conversation about a week before the U.S. Open," he said.

"Did where somebody else played and what promoter they played it with disqualify them for this event? We decided no on that, with all the awareness that not everyone would agree with that decision.

"Whether we all like it or not, in February 30 guys played for the same promoter in Saudi Arabia with an acceptable release from the PGA Tour, and for years the DP World Tour has had an event there, same promoter.

"I'm sure there are players that both came through our qualifying and maybe teeing it up that are sponsored by those different – so we asked ourselves the question: one week before, if you play somewhere where you're not approved to play, would you be disqualified for the 2022 U.S. Open?

"We said no. And we also had to ask the question, if you're going to put that kind of clause in, who gets in? It becomes a pretty slippery slope to try to apply that across 9,300 people."

Pressed on whether the decision may change in future, Whan added: "Yeah, I could foresee a day. Do I know what that day looks like? No, I don't.

"To be honest with you, what we're talking about was different two years ago, and it was different two months ago than it is today.

"I think everybody else that we work with needs to take a long-term view of this and see where these things go.

"We're not going to show a knee-jerk reaction to kind of what we do. But the question was, could you envision a day where it would be harder for some folks doing different things to get into a US Open? I could. Will that be true? I don't know, but I can definitely foresee that day.

"I think it would be a lot of hypotheticals for me to get what LIV is going to be by the time we're talking about this next year, but as we would do any year, we're going to definitely re-evaluate field criteria.

"We would any year. We will take a look at what the landscape looks like."

Rory McIlroy has always seemed to possess an older head on young shoulders.

Indeed, when the Northern Irishman burst onto the scene in 2009, his success belied his inexperience.

His first major title came at the 2011 U.S. Open, as he finished eight strokes clear of Jason Day at Congressional Country Club in Maryland. Three more followed in the space of three years; two at the US PGA Championship and one at The Open.

It has been eight years since McIlroy claimed a major honour, but heading to The Country Club in Brookline, Massachusetts, the 33-year-old's form is as strong as it has been since he lifted his second US PGA title in 2014.

And in recent months, McIlroy has been seen as one of the voices of reason amid the emergence of the LIV Golf Invitational, which started in London last week.

Charl Schwartzel won the inaugural event of the Saudi Arabia-backed breakaway competition, which has drawn the likes of Phil Mickelson, Sergio Garcia, Dustin Johnson and Bryson DeChambeau.

"If it keeps going the way it's going, it's going to fracture the game – sorry, it's going to fracture the game more than it already is," McIlroy, desperate to focus on his own game this week, told Sky Sports on Tuesday.

"The professional world in golf has already been fractured, there's so many different tours, so many different things to follow, and I've always been an advocate of trying to make it more cohesive and try to get people to work together more. This is ripping that apart.

"It's certainly a burden I don't need. But I have pretty strong views on the subject and I don't think it would be right for me to have these strong opinions and not share them."

Perhaps what golf needs more than ever right now is a unifying force that both players and fans can get behind. McIlroy might present just that.

Rory reinvigorated

It has been a brilliant year so far for McIlroy. According to official PGA Tour statistics, he ranks first for scoring average (68.842), top for strokes gained: tee-to-green (1.888) and strokes gained total (2.282), while he also comes in third for driving distance (319.1 metres) and strokes gained off-the-tee (.913) so far this season.

That form has resulted in six top-10 finishes, including his second place at the Masters in April, which came courtesy of a bogey free 64 in the final round, and his victory at the Canadian Open last week.

Defending his Canadian Open crown will have given McIlroy a timely boost heading to Massachusetts, following on from his eighth place at the US PGA Championship last month. He is in fine fettle, but needs to overcome his major hoodoo...

Getting over the line

Four major titles in the space of four years seemed to have paved the way for McIlroy to go on and join the true greats of golf, but it has not quite been that way.

Since winning the U.S. Open in 2011, McIlroy has failed to make the cut on four occasions at this major, though has recorded top-10 finishes in each of the last three editions of the tournament.

His best result at any of the majors since 2014 came at Augusta earlier this year, but as we have seen in other tournaments on the circuit, McIlroy has been known to squander strong positions, and he might even prefer to be in the chasing pack come Sunday.

In January 2021, McIlroy held the 54-hole lead at the Abu Dhabi Championship, but a final-round 72 saw him finish third. He finished five shots back from the winner and it was a similar story at the DP World Tour Championship in December, when he missed the chance to become the first player to win the event for a third time, giving up a last-day lead to finish five behind Collin Morikawa. 

Composure will be key for McIlroy this time around, should he be in contention.

A date with fate?

It might just be a coincidence, but fate is a funny old thing, and Sunday will mark 11 years to the day since McIlroy won his first major, when he claimed the U.S. Open so convincingly.

Another iron in McIlroy's fire could be that his win at the Canadian Open moved him onto 21 PGA Tour titles, edging him ahead of LIV Golf chief executive Greg Norman. Going on to seal his second U.S. Open triumph, 11 years since he claimed his first, would be a fitting way for McIlroy to prove he is on the right side of this particular divide.

Now, he just has to go out and perform.

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

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

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

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

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

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

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

The US Open begins on August 29 in New York.

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."

You don't know what you've got until it's gone.

That is how tennis fans the world over will be feeling after women's world number one Ash Barty shockingly announced her retirement on Wednesday.

Barty noted that achieving a lifelong goal of winning Wimbledon last year and being "spent physically" were motivating factors behind her decision.

The 25-year-old bows out on top having lifted her home slam at the Australian Open back in January, and is a three-time singles major champion.

Following news of her retirement, Stats Perform has delved into some of Barty's best facts from a stellar career.

SECOND ONLY TO OSAKA IN SLAMS SINCE 2016

There have been 14 different singles grand slam champions in a stacked women's game since 2016.

In that time, Barty has women three major titles – the second most alongside Angelique Kerber. Indeed, the only player to have more in the women's game over that period is Naomi Osaka with four.

Barty retires on a 13-match winning streak (all on hard courts), a run that of course includes her triumph at the Australian Open.

It matches the best run of her career, with Barty proving 13 is not unlucky for all by racking up the same amount of wins on clay and grass between May and June 2019 – that stretch having seen her lift her first slam at the French Open.

KVITOVA A FAMILIAR FOE

Barty has mixed it with the best in the women's game but she has faced no player more than two-time Wimbledon champion Petra Kvitova.

She has faced the Czech on 10 occasions, with the two sharing five wins apiece. Barty has also beaten Sofia Kenin, Karolina Pliskova, Shelby Rogers and Kiki Bertens on five occasions.

Caroline Wozniacki (3) and Mona Barthel (2) are the only players Barty has faced more than once but never beaten in women's tennis.

Conversely, Barty has defeated each of Marketa Vondrousova, Camila Giorgi, and Saisai Zheng four times from as many attempts, her most matches against any players against whom she has maintained a 100 per cent win rate.

STILL GOING STRONG

Never has the saying "always leave them wanting more" been truer than in the case of Barty.

She has averaged seven aces per match in women's tennis in 2022, the joint-most of any player alongside China's Qinwen Zheng and Hailey Baptiste of the United States.

Barty has made 77 aces in total in 2022, the joint-sixth most of any player but 30 fewer than WTA leader Madison Keys (107).

Moreover, she has won 94 per cent of service games, the highest rate of any player and eight percentage points higher than second-ranked Elena Rybakina of Kazakhstan.

Barty won 71 per cent of her points when serving this calendar year, the highest rate of any player and four percentage points higher than second-most Rybakina.

Indeed, Barty did not lose a match in her shortened 2022 season, finishing 11-0 and winning 25 of her final 26 matches. 

114 WEEKS AND OUT

Barty is the second female player to step away from the game when ranked world number one, with Justin Henin having done so in 2008 after 61 consecutive weeks at the top.

Barty does so having racked up 114 straight weeks at the summit of the rankings, a run which represents the fourth longest in the history of the WTA Tour behind only Steffi Graf (186 weeks), Serena Williams (186) and Martina Navratilova (156).

Her accumulated total of 121 weeks represents the seventh highest of all time. Barty finishes her career with 15 singles titles in total and 12 in doubles, while she ends with a 305-102 win-loss singles record, and 200-64 in doubles.

Ash Barty stunned the sporting world on Wednesday by announcing her retirement from tennis, bowing out as the top-ranked player in the women's game.

The popular 25-year-old has not featured since winning her home grand slam at the Australian Open in January, becoming the first female Aussie singles champion of the tournament since Chris O'Neil in 1978.

Announcing the news on her Instagram page, Barty cited achieving a lifelong goal of winning Wimbledon last year as a primary factor behind her decision as well as being "spent physically".

But Barty is by no means the first sporting hero to retire at the top of their game. Below we take a look at some other examples of those who have exited as champions.

ALAIN PROST

The 1993 Formula One season was largely dominated by one man – Williams driver Alain Prost. The Frenchman had to battle hard with the iconic Ayrton Senna at the start of the campaign, with them each taking three wins from the first six races of the season. However, a run of four straight victories for Prost were followed by a string of retirements for Senna, ensuring a fourth world title that provided the ideal ending to a glittering career.

ALEX FERGUSON

One of the most successful managers in world football, Alex Ferguson began a 27-year stint at Manchester United after an excellent spell at Aberdeen. The Scot won 28 major trophies at Old Trafford, including 13 Premier League titles, five FA Cups and two Champions Leagues. His final trophy came with top-flight glory in 2012-13, and 17 days later he brought the curtain down.

PEYTON MANNING

Considered one of the greatest quarterbacks of all time, Peyton Manning won his first Super Bowl with the Indianapolis Colts in 2007 and, after an injury-blighted season that raised doubts about his ability aged 39, he added a second with the Denver Broncos in 2016, bowing out on the ultimate high.

RICHIE MCCAW, DAN CARTER

New Zealand became the first nation to successfully defend the Rugby World Cup trophy by beating Australia 34-17 in the final at Twickenham in 2015, adding to their success on home soil four years prior. It proved the end of the line for captain Richie McCaw, who was at the time the most capped player in rugby union with 148 appearances for the All Blacks, as well as mercurial fly-half Dan Carter. Ma'a Nonu, Conrad Smith and Kevin Mealamu were also among an influential contingent that opted to end their international careers.

PETE SAMPRAS

In defeating Andre Agassi in the final of the 2002 US Open, the same opponent he overcame to win his first grand slam 12 years prior, Pete Sampras secured his place among the greats in men's tennis. It was a then-record 14th major singles title for a male player for the American, a milestone that has since been surpassed by Roger Federer, Rafael Nadal and Novak Djokovic, but he did not compete again and announced his retirement almost one year later.

PHILIPP LAHM, MIROSLAV KLOSE

At 31 you still have a number of years ahead of you in football. However, after lifting the World Cup trophy with Germany in 2014, Philipp Lahm decided to call time on his international career and focus on club football with Bayern Munich. The versatile full-back made 113 appearances for his country and was joined by fellow centurions Per Mertesacker and Miroslav Klose – whose tally of 71 international strikes is a German record – in switching focus to domestic matters.

MARION BARTOLI

A first grand slam at Wimbledon in 2013 appeared to be the breakthrough moment for a 28-year-old Marion Bartoli, but reality proved very different. The Frenchwoman defeated Sabine Lisicki – who had overcome pre-tournament favourites Serena Williams and Agnieszka Radwanska – in the All England Club final, but announced her retirement during the Western and Southern Open just 40 days later due to persistent injuries. She attempted a comeback in 2018 but continued setbacks and injuries curtailed those plans.

NICO ROSBERG

Nico Rosberg had engaged in several intense battles with Lewis Hamilton before finally getting the better of his Mercedes team-mate to become Formula One world champion in the 2016 season. Still only 31, Rosberg had potentially several more years in F1 but the German instead opted to depart having reached the pinnacle of his sport.

The Grand Slam Board has announced that first-to-10 tie-breaks will conclude the final sets of all four majors with immediate effect.

Starting with May's French Open, the decision is being adopted on a trial basis with the aim of providing "greater consistency" to the rules when matches go the distance.

Prior to Wednesday's announcement, the French Open, Australian Open, US Open and Wimbledon each had their own rules when games went to a deciding tie-break.

The Australian Open is the only grand slam to already employ the first-to-10 rule at 6-6.

Wimbledon previously played first-to-seven at 12-12, while the US Open played a first-to-seven at 6-6.

There has not previously been a deciding tie-break at Roland-Garros, with all matches continuing until a player secured a two-game lead in the decider.

A statement released on behalf of Grand Slam Board members Jayne Hrdlicka, Gilles Moretton, Ian Hewitt and Mike McNulty confirmed the changes.

It read: "The Grand Slam Board's decision is based on a strong desire to create greater consistency in the rules of the game at the Grand Slams, and thus enhance the experience for the players and fans alike.

"This trial, which has been approved by the rules of the tennis committee governed by the ITF, will apply to all Grand Slams across qualifying, men's singles and doubles, women's singles and doubles, wheelchair and junior events in singles, and will commence at the 2022 edition of Roland-Garros."

The rule change will be reviewed after a full Grand Slam year and will remain in place should it be deemed a success.

The tweaks to the current format will ensure no repeat of John Isner's marathon battle with Nicolas Mahut at Wimbledon in 2010, which the American edged 70-68 in the final set of their first-round match.

The ATP, WTA, International Tennis Federation (ITF) and the four grand slam organisers have announced the Tennis Plays for Peace campaign.

Along with the campaign, which will include efforts on social media and at tournaments, each of the seven organisations has pledged to donate $100,000 to humanitarian relief efforts in Ukraine.

Russia invaded the country on February 24 and the conflict is still ongoing. Well over one million refugees are estimated to have fled to neighbouring countries in Europe.

A joint statement from tennis' governing bodies on Tuesday explained that the campaign is not just about donations.

"The seven bodies will also signal support via their social and digital platforms by prominently featuring the Ukraine ribbon icon, with everyone in the tennis ecosystem encouraged to use the hashtag #TennisPlaysforPeace," it read.

"In addition, physical ribbons will be distributed for ATP and WTA players to wear at the upcoming BNP Paribas Open tournament in Indian Wells."

Last week, the ITF banned Russian and Belarusian teams from competing at the Davis Cup or the Billie Jean King Cup. Russia are the holders of each title.

The ATP and WTA, meanwhile, allowed Russian and Belarusian athletes to carry on competing, but only under neutral banners.

That includes ATP world number one Daniil Medvedev and WTA world number three Aryna Sabalenka.

Roger Federer says he hopes to return to action by the end of the summer, with his recovery from knee surgery likely to rule the 20-time grand slam winner out of Wimbledon.

The 40-year-old underwent surgery on his right knee for the third time last August, and has missed five of the last seven grand slams.

Federer made the quarter-finals at Wimbledon last year, but coach Severin Luthi recently said that he "can't imagine" the eight-time Wimbledon winner featuring in London this summer.

Federer has now provided an update on his recovery to Swiss broadcaster SRF, saying that the end of summer or start of autumn is a realistic target for his return, which could mean he is back for the US Open that starts on August 29.

However, he feels "positive" about his return to the court whenever that comes.

"It will certainly be a while," Federer said. "The end of the summer, early autumn, [that's] where I'm aiming for a comeback.

"It's [the knee] fine. Much better. Obviously, I was on crutches for two months, so you have to start from the bottom.

"It [the surgery] was certainly the right thing to do, the knee wasn't right after Wimbledon [last year], so it couldn't go on.

"Currently I'm in three parts. First, the whole rehab, getting back on your feet at the beginning. Then afterwards, learning to walk and building up the whole thing.

"It's only now where I'm at the phase where I can start thinking about my comeback. I had a very good MRI a few weeks ago, which makes me feel very positive."

Federer's tally of 20 career Grand Slam titles was surpassed by Rafael Nadal in January's Australian Open, and the duo are set, fitness permitting, to team up to represent Europe in the Laver Cup, which takes place in September.

The timeline for Federer's recovery also means that he will miss the second slam of 2022, May's French Open at Rolland Garros.

Rafael Nadal would "welcome" seeing Novak Djokovic play at future grand slam tournaments if he is granted permission to do so unvaccinated against COVID-19.

World number one Djokovic has courted controversy for his views on being jabbed and was last month deported from Australia on the eve of the Australian Open.

Djokovic has confirmed he is willing to miss future slams after stating he was prioritising his right to choose what to put into his body above his sporting ambitions.

In Djokovic's absence, Nadal became Australian Open champion and now has 21 titles – the most for a male player.

Nadal believes that any further omissions from Djokovic would only be harmful to the Serbian's chances of history not the slams themselves, but he would have no issue with his rival playing in the sport's biggest tournaments.

Speaking ahead of his return to the ATP Tour in Acapulco, Nadal said: "It will affect Novak's [grand slam] history if he can't play.

"It will affect him, not the grand slams themselves. Whoever wins the most slams – it will be what it will be. Everyone takes their own decisions and must live with them.

"In that sense, hopefully the pandemic subsides and we stop having so many deaths around the world and this horror ends, and we can return to normality – not for Novak but for the world in general.

"There are many people that have suffered, but if Novak can play the grand slams unvaccinated, then he is welcome."

Nadal defeated Daniil Medvedev in an epic Melbourne showpiece to become the first man to 21 slams, but he says the achievement has not changed his life.

"Absolutely nothing has changed having 21 slams, I won't lie to you," he added.

"From 20 to 21 there is not a very large difference. Life goes on exactly the same. The only thing that has changed is that now I play tennis, which a few months ago I couldn't.

"I am very happy for everything that happened in Australia, it was very unexpected, especially before the tournament started. In my life, nothing has changed. No title is going to change what is important in my life, which are other things.

"Already, at 35 years old, I have a lot of experiences behind me, of successes and bad moments and these sensations already help me to live in a more calm and different way."

Novak Djokovic has said missing grand slams including the French Open and Wimbledon will be "the price I am willing to pay" for resisting the COVID-19 vaccine.

Last month, the world number one and 20-time grand slam winner was deported from Australia on the eve of the Australian Open after his entry visa to the country was cancelled.

That stemmed from Djokovic refusing to join the overwhelming majority of fellow tennis stars in being vaccinated against coronavirus, and amid controversy over how he handled getting the virus himself in December.

In a new interview with the BBC, Djokovic said he was prioritising his right to choose what to put into his body above his sporting ambitions.

The 34-year-old Serbian declared his stance is likely to keep him sidelined for "most of the tournaments" at present.

Djokovic is set to make his return to the court at the Dubai Duty Free Tennis Championships later this month, with vaccination not a requirement. He has been included on the entry list for next month's Indian Wells Open, but that is a tournament he may have to sit out.

He confirmed in the BBC interview that he has still yet to be vaccinated, though did not entirely rule out the prospect in the future.

"I have not," he said. "I understand and support fully the freedom to choose whether you want to get vaccinated or not."

Prior to entering Australia, where he was obliged to confirm his status, it was only widely assumed that Djokovic had not been inoculated.

Now he is keen to "speak up ... and justify certain things", adding: "So I was never against vaccination. I understand that globally everyone is trying to put a big effort into handling this virus and seeing hopefully an end soon to this virus.

"And vaccinations are probably the biggest effort that was made on behalf of the planet. I fully respect that, but I've always represented and always supported the freedom to choose what you put into your body. For me that is essential. It's really the principle of understanding what is right and what is wrong for you.

"And me, as an elite professional athlete, I've always carefully reviewed and assessed everything that comes in, from the supplements, food, the water that I drink or sports drinks. Anything really that comes into my body as a fuel.

"Based on all the information that I got, I decided not to take the vaccine as of today. I keep my mind open because we are all trying to find collectively a best possible solution to end COVID. Nobody really wants to be in this kind of situation that we've been in collectively for two years."

Djokovic is the reigning French Open and Wimbledon champion and, after Rafael Nadal's Australian Open triumph, he has been bumped down to joint second on the all-time men's grand slam list. Missing majors at this stage of his career could be a crushing blow to Djokovic's hopes of finishing top of that pile.

"I'm part of a very global sport that is played every single week in a different location, so I understand the consequences of my decision, and one of the consequences of my decision was not going to Australia, and I was prepared not to go," Djokovic said.

"I understand that not being vaccinated today I am unable to travel to most of the tournaments at the moment. That is the price I am willing to pay."

He looked to disassociate himself from the anti-vax community by saying he had "never said I am part of that movement" and declaring that was a "wrong conclusion" to draw.

At the same time, Djokovic concurred when asked if he was willing to sacrifice the chance to be seen as the greatest player of all time, and to travel to Roland Garros and the All England Club this year.

"Because the principles of decision-making on my body are more important than any title or anything else. I'm trying to be in tune with my body as much as I possibly can," Djokovic said.

"I say that everyone has a right to choose to act or say whatever they feel is appropriate for them."

Spanish tennis great Manolo Santana, a four-time grand slam winner, has died at the age of 83.

Santana won the US Open, Wimbledon and the French Open twice during the 1960s, during which time he spent a period as world number one.

He also won the men's singles tennis tournament at the 1968 Olympics, though it was not recognised as a medal event at the time, while also winning the French Open men's doubles in 1963 and the Davis Cup with Spain on three occasions.

Santana retired in 1977 and in more recent times was regularly seen watching countryman Nadal – the only Spaniard to have won more grand slam titles – from the stands.

Nadal led the tributes to Santana on Saturday with an emotional post on social media.

"I have just received the terrible news of the death of our great Manolo Santana," he wrote on his official Instagram account.

"As I have said many times in the past: thank you very much for what you did for our country and for leading the way for so many. 

"You have always been a reference, a friend and a person close to everyone.

"We will miss you Manolo; you will always be unique and special. Greetings to your family and a lot of strength at this time. We will never forget you."
