Elena Rybakina overcame a slow start to the defence of her Wimbledon title to beat Shelby Rogers in three sets.

Rybakina was playing on Centre Court for the first time since winning her maiden grand slam title 12 months ago and American Rogers threatened to produce some Independence Day fireworks as she took the opening set in style.

But, despite a recent illness which saw her pull out of the Eastbourne tournament last week, she found her feet and reminded everyone why she triumphed here last year by overrunning her opponent in the final two sets to claim a 4-6 6-1 6-2 victory.

She entered the court after eight-time men’s champion Roger Federer had been welcomed by the crowd and did not start well as Shelby broke her serve in the opening game of the match.

Rogers was able to save a break-back point at 2-1 and then produced some fine hitting that enabled her to take the advantage.

But that was as good as it got as Rybakina kicked into gear and raced away with the second set, breaking serve twice to take it in 29 minutes.

An early break in the decider proved key and Rybakina was able to move safely into the second round.

She said in her on-court interview: “It was really tough for me today, I was pretty nervous, I cannot even hide it. The double fault said it all in the first game of the match. I am really pleased to get to another round.

“I am feeling much better. Hopefully this win gives me more confidence for the next round.”

Her victory was the only women’s match able to be completed in the first four-and-a-half hours of play on Tuesday as heavy rain just after midday stopped all action on the outside courts.

Oisin Murphy will partner Chaldean as he heads to France this weekend for the Prix Jean Prat at Deauville.

The Andrew Balding-trained Frankel colt was last seen finishing second to Paddington in the St James’s Palace Stakes at Royal Ascot, prior to which he was an impressive winner of the 2000 Guineas at Newmarket in early May.

Paddington is now the Coral-Eclipse favourite and could step up to a mile and a quarter Sandown on Saturday, whereas Chaldean will return to a seven-furlong trip in the Deauville Group One on Sunday.

Frankie Dettori, who has been aboard for Chaldean’s last five starts, is unable to take to take the ride as he is serving a suspension for careless riding at the Royal meeting.

Murphy, who is Balding’s principal rider, will therefore take the reins at the weekend having ridden the Juddmonte-owned three-year-old several times before at home.

Barry Mahon, racing manager to Juddmonte, said: “Obviously Frankie is not around this weekend, which is unfortunate, but what can we do?

“It’s disappointing, but we’re in good shape and Andrew is happy with him.

“We’ll kick on and if he’s happy with him tomorrow morning after he does a little bit of work, he’ll be on track for Sunday.

“Oisin has ridden him at home plenty. He’ll sit on him again tomorrow. I know he’s never ridden him on the track, but he knows the horse well and he’s an integral part of Andrew’s team, so it is nice that he can get aboard on Sunday.

“He is a Dewhurst winner and not short of speed and Frankie’s first words when he got off him at Ascot were, ‘jeez, he has got lots of speed’, and we threw the July Cup out there for a while and we didn’t think that was the right thing to do.

“Seven furlongs looks a good spot for him and he is in good shape and hopefully it will work out.

“He’s versatile. His pedigree is all speed, his two-year-old form is all seven furlongs, so I think trip-wise he is fine, seven to a mile. I thought after the Guineas he’d stretch out a little bit, but I’m not so sure now. We’ll have to see how the year progresses.”

Also heading for Deauville for the same race is Kevin Ryan’s Hi Royal, second behind Chaldean in the Guineas and third behind Paddington and his stablemate Cairo in the Irish equivalent of the race at the Curragh.

His Newmarket run came at a huge price of 125-1, but he was an 11-2 chance in Ireland once his ability had been proven in a Classic.

Adam Ryan, the trainer’s son and his assistant, said: “Hi Royal will go to the Prix Jean Prat on Sunday. He is in great order. He was never in at Ascot, so he is nice and freshened up since his run in the Irish Guineas.

“Obviously that form has worked out extremely well, because Paddington has probably announced himself as the leading three-year-old. I think we would have been second to him, had he not received a bump.

“His form is rock solid and it will be nice to hope that he can have his day in the sun.

“I think he is pretty versatile ground-wise. He seems to act on anything and is a fine-moving horse. You probably don’t want extremes with him, but I don’t think he’d shy away from very much either.

“I believe James Doyle will be riding him. He has ridden Group One winners for us and Mr (Jaber) Abdullah (owner).”

Beyond Deauville, there will be some consideration as to which path Hi Royal takes throughout the rest of the season, with the horse a year younger than stablemate and fellow miler Triple Time.

“It is quite difficult to say what plans will be for Hi Royal, as he is in the same mile division as Triple Time and you get to that point where the three-year-olds have to take on the older horses,” Ryan said.

“Again, it is something you have to sit down and discuss with connections and make the best plan possible.

“It is hard enough to win these races, you don’t want to be taking each other on for the same yard as well. We’ll look forward to Sunday first and take things from there.”

World number one Carlos Alcaraz laid down a serious Wimbledon marker with a three-set defeat of Jeremy Chardy in the first round.

The 20-year-old Spaniard is seen as the most realistic challenger to Novak Djokovic’s bid for an eighth title this fortnight.

He proved his blossoming grass-court credentials by winning at Queen’s last weekend, and then produced an impressive all-round display, dismantling Chardy for two sets before digging in to take the third for a 6-0 6-2 7-5 win under the roof on Court One.

Chardy had announced he would retire after the Championships, with the London-based Frenchman calling time on his career 18 years after winning the Wimbledon boys’ title.

The 36-year-old, who reached a career high of 25 in the world, had said beforehand the match would “be a great end, no matter what”.

He may have revised that opinion after a first set which lasted just 22 minutes and in which he could not buy a first serve, throwing in seven double-faults to hand Alcaraz a bagel for lunch.

The match began at just after 1pm, but it was nearly quarter-to-two by the time Chardy finally got a game on the board.

Alcaraz had only ever played six matches on grass before Queen’s. But, all venomous serves, thunderous forehands, sliced backhands and the occasional beautifully disguised drop shot, he now looks ominously at home on the surface.

Chardy was two sets behind after less than an hour, yet, out of the blue and willed on by a crowd wanting to see at least something of a contest, he converted a break point at the fourth attempt to lead 4-2 in the third.

It was a fleeting show of defiance, however, with Alcaraz breaking straight back and going on to complete the victory in an hour and 53 minutes.

“I think I played really well at the beginning of the match but in the third set he showed his level,” said Alcaraz.

“I like to play rallies and battles, let’s say, and I’m really happy to have played at a great level and get through this first round.

“Without the roof and sun it’s better for me and everyone, but I have to be really focused. The sound of the ball with the roof is beautiful.”

Jack Kennedy registered his first victory since returning from a lengthy injury lay-off aboard I A Connect in the equuip – A Leg Up For Thoroughbred People Beginners Chase at Tipperary.

Kennedy broke his leg for a fifth time in a fall at Naas back in January, with the 24-year-old only returning to action at Cartmel on Sunday.

With Davy Russell’s retirement, Kennedy had not long assumed the role as clear number one for Gordon Elliott before sustaining the injury, which forced him to miss the Dublin Racing Festival in February as well as Cheltenham, Aintree, Fairyhouse and Punchestown in the spring.

Teaming up with the Elliott-trained I A Connect (4-1), Kennedy and his mount survived a bit of a sticky jump at the penultimate obstacle before eventually fending off Walnut Beach by a head in a thrilling finish.

Kennedy said: “That was brilliant and I’m delighted. He pecked a bit at the back of second-last, but he stays and probably wants further than that.

“I sent him on early as all he does is stay and to be fair to him he stuck his head out and battled.”

Kennedy admitted he had been unsure how he would feel on his second day back, but is now eagerly awaiting the Galway Festival at the end of the month.

He added: “I’m better today than I thought and had a good blowout at Cartmel on Sunday.

“I started back riding out six weeks ago, had three rides at Cartmel and have three today. Touch wood, the leg feels good.

“I didn’t put myself under any pressure to be back for the spring festivals, gave it more time then and I’m looking forward to Galway now.”

Triple Time looks set to bypass the Qipco Sussex Stakes and head to France for the Prix Jacques le Marois after his impressive success in the Queen Anne at Royal Ascot.

A son of Frankel, the Kevin Ryan-trained colt won two of his four starts as a juvenile but was limited to two outings last year, winning the Group Three Superior Stakes in September before finishing seventh in the Prix Daniel Wildenstein on Arc weekend.

Having been a late withdrawal from the Lockinge Stakes with a stomach cramp and having his first run since October, the 33-1 shot overcame a 262-day break to beat a strong field at Ascot, which included top-class winners Inspiral, Modern Games, Angel Bleu and Native Trail.

Under Neil Callan, the Sheikh Mohammed Obaid Al Maktoum-owned colt had a neck to spare over Inspiral, whose connections are similarly eyeing a trip to Deauville, where the filly could bid to win the race for a second year in succession.

Adam Ryan, son and assistant to the Hambleton trainer, said: “Triple Time has come out of the race absolutely fine and done very well.

“It was his first run of the year and so he’d be entitled to come on for that as well. It was impressive what he did.

“To do that after such a long time off, not only to do that against Group One horses, but horses who’d had a run under their belt, was great.”

Though Triple Time holds an entry in the Sussex Stakes and is currently the general third-favourite behind Paddington and Inspiral, connections are keen on the August 12 Group One contest over a mile at Deauville instead.

“I think we are probably leaning towards the France and the Prix Jacques le Marois,” said Ryan. “It’s nice timing between races and it will be more of a conventional track as well. He is obviously in the Sussex, as it was an early-closing race.

“It is tough because you have to make the entries, but at the same time it is never firmed up, because of ground etc. Horses map their own way out. Group One horses, we all know the races for them.”

The North Yorkshire yard is no stranger to heading abroad and Triple Time’s success earned him an expenses-paid berth to the Breeders’ Cup Mile at Santa Anita in November, courtesy of the Breeders’ Cup Challenge Series.

The Ryans finished second in the Juvenile Fillies Turf with East in 2018 and gained a first success at the meeting two years later when Glass Slippers struck in the Breeders’ Cup Turf Sprint.

Asked of the prospect of sending Triple Time Stateside at the end of the season, Ryan added: “Through all the years we’ve sent a few runners and obviously have had some success. The thing is with Triple Time, he’ll be a stallion for the future now and it is something you have to discuss with connections.

“You have races like the QEII around the same time and is it better to go there (Ascot) on a track you know, without all the travel. Those sort of decisions are for the people above my pay grade.

“It is nice to have those sort of options to talk about. The good thing is he has that Group One win under his belt and everything is a bonus.

“You want to see him as an absolute star, but we’ve got the most important hurdle out of the way now. He’s proved he’s up to that calibre.”

Ryan also confirmed last season’s Group One Sun Chariot winner Fonteyn has been retired.

The daughter of Farhh won the Listed Michael Seely Memorial at York and ended her career in style when beating Laurel at Newmarket in October.

Ryan said: “Fonteyn retired after her last run. Going into this year there were only a couple of fillies-only Group Ones for her here and she wasn’t the best of travellers, so that scuppers any chance of going to France or Ireland.

“We were very limited, so we discussed with Sheikh Obaid and the best option was to retire her and go out on a high.”

Connections of Stay Alert have lodged an appeal against the decision of the Curragh stewards not to reverse the placings in Saturday’s Group One Pretty Polly Stakes.

The Hughie Morrison-trained four-year-old was beaten two lengths by George Boughey’s Via Sistina in the 10-furlong contest, but the Jamie Spencer-ridden winner hampered a number of rivals in the closing stages.

The interference occurred as the field approached the final furlong when Via Sistina hung right into the path of eventual fourth Rosscarbery, with jockey Billy Lee forced to check his mount, while the Ronan Whelan-ridden Stay Alert was also tightened up by the winner.

While the Irish Horseracing Authority Regulatory Board confirmed Spencer has appealed the severity of the six-day ban for careless riding he received following the race, Morrison felt the incident had proved crucial to the result.

He said: “The connections have appealed. As he (Spencer) pulled that horse out, it was hanging right.

“He then continued to ride it for possibly a furlong and he didn’t make any correction until he’d seriously endangered two horses and two jockeys.

“If they can tell me they didn’t feel endangered, then end of story. It was hanging all the way and should have been corrected at least 100 metres before the incidents took place.

“When you get stopped in your run when you are quickening up and you have 100 yards to make up three lengths, you are lucky to make up one.

“Any other sport and you’d be thrown out, more so because the fourth horse (Rosscarbery) was prevented from coming third, which was quite significant when you are talking about a Group One.”

Stay Alert had won the Group Three Legacy Cup at Newbury in September and had dropped back in trip on her seasonal bow when fifth to Free Wind in the Middleton at York in May.

Equipped with a first-time tongue strap, she travelled well and showed marked improvement at the Curragh, and Morrison added: “It helped her, made her concentrate and did everything we expected it to do. I don’t think she has a wind issue, it just helped her concentrate on the job.

“She showed how good she is. She is in the Yorkshire Oaks and there are a couple of races in France. Those are in the middle of August – there is nothing else for her.

“She could go for a colts’ race somewhere, that might be tempting, but you never know what the ground will be like in Germany, and you’d like to win a big race before you go to France.

“This was the target for her all year, so it was frustrating. We got everything right, but hit the crossbar. We’d like to win a good one and we’d like a clean fight as well.”

Roger Federer showed he is still king of Centre Court after a special welcome marked his record-breaking achievements at Wimbledon.

The 41-year-old was back at the scene of his eight titles for the first time since he retired last September and was celebrated in the Royal Box ahead of the start of play on Tuesday.

Federer, who was fresh from appearing on stage with Coldplay in Zurich over the weekend, received a rapturous standing ovation and was visibly moved before taking his seat next to the Princess of Wales.

The celebration did threaten to upstage Elena Rybakina, the defending women’s champion who began her title defence against American Shelby Rogers.

It was the first of three scheduled matches on the main show court on day two of the Championships, with two-time winner Andy Murray taking on fellow Briton Ryan Peniston later.

Top men’s seed Carlos Alcaraz was in action under the roof on Court One but play elsewhere was suspended due to rain in SW19.

Highfield Princess will head for the King George Qatar Stakes at Goodwood after her two valiant efforts in defeat at Royal Ascot.

While the Goodwood race is only a Group Two, it is worth £170,000 to the winner and she will not have to carry a Group One penalty.

Quinn had considered the July Cup, but decided to keep her to five furlongs for the rest of the season, which means she will not be defending her Prix Maurice de Gheest title in Deauville which she won last season.

“We decided against the July Cup and she’s going to go to Goodwood,” said Quinn.

“That’s a slight change in plan, but we’re going down the sprinting five-furlong route, that’s our thinking.

“We thought, like last year, we’d give her a bit of a break now, a bit of a midsummer break and then head to Goodwood.

“She doesn’t have a Group One penalty which is handy.

“After Goodwood, we’ll then look at two of the races she won last year (Nunthorpe Stakes at York and Flying Five at the Curragh).”

Leigh have stolen the show in Betfred Super League this year by surging towards an improbable play-off place in their first season back in the top flight.

With the Leopards looking strong alongside Catalans Dragons, Wigan and St Helens, a furious battle is developing for the final two post-season slots – not to mention a potential twist at the bottom of the table.

With 10 weeks of the regular season remaining, the PA news agency runs the rule over the 12 teams ahead of a potentially pivotal weekend of action.

CATALANS DRAGONS (Pld 17/Pts 26)

Steve McNamara’s men head into Saturday’s home clash with Huddersfield on a high after seven straight wins.

Boosted by the exuberant form of winger Tom Johnstone and underpinned by the ever-evolving Arthur Mourgue, consistent Catalans look strong bets to land their second League Leaders’ Shield.

LEIGH (17/22)

Spectacularly bucking the trend of previous promoted teams, Adrian Lam’s side are riding high in second place as they prepare to head to struggling Castleford.

With yards from John Asiata, points from Josh Charnley and precision from Lachlan Lam, there is little sign of the Leopards losing their spots.

WIGAN (17/22)

Matt Peet’s men go to resurgent Wakefield on Friday on a high having rebounded well from last month’s mauling by St Helens with two straight wins.

With Jai Field back in his favoured full-back role and Bevan French busier in the halves, the Warriors look in good shape for another post-season assault.

WARRINGTON (17/22)

Four league defeats from five and the embarrassing exit of Josh McGuire have rendered Warrington’s eight-game unbeaten start to the campaign a distant memory.

Another loss to St Helens on Friday would pile more pressure on boss Daryl Powell, with his side facing the real possibility of sliding all the way out of the top six.

ST HELENS (16/20)

Some recent displays suggest Saints are once again coming good at the right time but last month’s surprise blip at Hull indicates Paul Wellens still has some work to do.

A win at Warrington would ease those fears and arguably confirm Saints’ status as favourites to reel off a fifth consecutive Grand Final triumph.

SALFORD (17/20)

Paul Rowley’s men face Leeds on Sunday in a match that could have a major say on which team goes on to seal a play-off slot.

Despite once again defying the odds for much of the campaign, back-to-back heavy losses – most recently at rock-bottom Wakefield – have raised questions over the Red Devils’ ability to stay the course.

HULL KR (17/18)

Injury-ravaged Rovers have shown signs of buckling in recent weeks and head into Sunday’s derby with scant hope of repeating their 40-0 humiliation of Hull at the MKM Stadium in April.

Jordan Abdull is their latest big loss, but despite a major battle to retain their top six slot, Rovers’ fighting spirit cannot be questioned.

LEEDS (17/16)

Unfathomable for much of the season, Rohan Smith’s men finally appear to have found their groove, thanks in no small part to the superb form of Blake Austin and the muscle of mysteriously departing prop Sam Walters.

Heading to Salford on Sunday, the Rhinos’ traditional late-season surge is under way.

HULL (17/14)

Even last week’s gutsy defeat by Catalans could not disguise the significant improvements made by Tony Smith’s side since a torrid start to the campaign.

With halves Jake Clifford and Jake Trueman outstanding, and homegrown Brad Fash typifying their fresh impetus up front, FC could end up running the top six close.

HUDDERSFIELD (16/10)

Huddersfield’s only solace in a season to forget is that there are two teams below them who have been much worse.

But with Wakefield stirring, under-pressure Giants boss Ian Watson needs to summon something from his tired side, unrecognisable from that basking in a Wembley Challenge Cup final just over 12 months ago.

CASTLEFORD (17/8)

Cas are capable of summoning good days – see their Magic Weekend win over Leeds and the recent success against Warrington – but remain ravaged by inconsistency and, despite the encouraging loan signing of Riley Dean, have every reason to be looking over their shoulders with increasing alarm.

WAKEFIELD (17/4)

The top flight’s great escape act are at it again, if last week’s thumping win over Salford is anything to go by.

Fully behind boss Mark Applegarth and galvanised by the recent arrival of Luke Gale, Wakefield would issue another major statement if they manage to get something from Wigan on Friday night.

Michael Dods is planning a return trip to Ireland with Commanche Falls following his comfortable win at the Curragh on Sunday.

The dual Stewards’ Cup winner notched his first victory at Listed level by a length and a half under Connor Beasley.

Perhaps unsurprisingly, sprint king Dods is eyeing another trip over the Irish Sea for the six-year-old, for the Rathasker Stud Phoenix Sprint back at the Curragh next month.

“He’s won the Stewards’ Cup twice and he’s in it again, but he’s now rated 112 so he’d have a lot of weight this year,” said Dods.

“He ran really well at York against proper Group One horses (third in Duke of York Stakes). He’s Dakota Gold’s half-brother, but they are totally different because with Commanche if he is travelling well at halfway they are going too slow.

“When we saw him off the bridle on Sunday we knew he’d finish strong and he did, he grinds it out rather than quickens. He also doesn’t mind faster ground, whereas Dakota needs a bit of cut.

“He might have an entry in the Hackwood (at Newbury), but there’s the Group Three Rathasker Stud race in early August at the Curragh I think he’ll end up going for. There’s also a race at Baden-Baden we could look at.”

Classic-winning jockey Eddie Ahern, whose 10-year ban for passing on inside information and failing to ride a horse on its merits came to an end in May, is exploring all options for the future as he begins riding out for William Haggas.

The 45-year-old rode work on Saturday morning for the first time and was in situ at Somerville Lodge on Monday morning, although a serious leg injury could put paid to any thoughts of a return to race-riding for the time being.

“Ten years is a long time and it has felt like forever,” said Ahern. “I think I’m a long way from a comeback, because I had such a bad leg injury in May last year.”

A badly-broken leg twice rejected a nail incision, causing severe infections, and Ahern required a lengthy stay in hospital, diminishing hope that he could return to race-riding.

“I was in a lot of pain. I’m not in any pain now and the bone has completely healed. I have a bit of a limp and I’m still not running yet.

“I put myself on a strict diet when I was in hospital, but I weighed myself the other day and I was 10 stone.

“The leg is good and strong, but I can’t go out and put the sweatsuit on and run three miles, all the time I’m limping.

“However, I am blessed with a physique which adapts easily to the weight demands of riding on the Flat so, with the right diet and routine, making the weight would be no problem to me.”

A former Irish champion apprentice, Ahern was found guilty by a British Horseracing Authority disciplinary panel of conspiring to commit a corrupt or fraudulent practice in relation to the laying of five horses between September 2010 and February 2011.

He was also found to have intentionally failed to ensure Judgethemoment was ridden on its merits at Lingfield in January 2011, and of passing information for reward.

Ahern, who won the Irish St Leger in 2011 for John Gosden when Duncan dead-heated with Jukebox Jury, was subsequently banned for 10 years in 2013.

“Obviously, I felt the punishment was harsh, but I have served my ban and I need to move on,” he said.

“I am allowed to ride out for trainers, and while I still haven’t fully recovered from a broken leg, I wanted to get my leg stronger, get myself fit and get back into riding racehorses.

“I have been riding showjumpers, it has really helped get me back riding and strong again, but I wanted to get back on the racehorse again. It is where my passion lies and I have really missed it. It is really nice to get on a nice three-year-old or four-year-old.”

Ahern and his partner, top showjumper Holly Smith, rent a yard in Leicestershire, where she is rebuilding her string. Ahern plans to break-in yearlings, pre-train and prepare breeze-up horses for trainers over the winter.

Though keen to build the business further, Ahern is not ruling out a return to the saddle, but admits it will be tough to do.

He said: “I am really thankful for the opportunity to ride out for Mr Haggas.

“I rode a lot of winners, including one at Royal Ascot, for him. I want to see if the bug still there, whether the fire is still in my stomach.

“I haven’t ridden racehorses in a while and when you are a work rider, it is all about educating the horses and getting the pace right, and feeding back as much information to the trainer as possible. I wanted to get back doing all that, especially with such high-class horses.

“William and (wife) Maureen know how much I admire them as people and as trainers.

“I love them, the lads in the yard, the yard itself and love the routine and the set-up. I missed seeing everyone’s faces. It is nice to see the riding-out boots and breeches.

“I know all the tracks and the gallops, I know how Mr Haggas wants his horses ridden and know how they should be ridden. I just want to get back doing all that again.

“I don’t know if I will make a comeback. What I do know is I want to get fit and get strong, and go down to ride work.

“I know the weight will fall off. I’m using all the old muscles I used to use before. My legs need to get stronger and my body to get stronger, but I’m 45. I’m under no illusions – I have a ‘Dad-bod’ at the moment!

“I feel I’m a lot older, I have other ideas in my head, breaking, pre-training, breeze-ups. Race-riding is a young man’s game. With one meeting a day and no saunas, it just makes life hard for jockeys, but I certainly wouldn’t rule it out.

“I’m happy to work hard for Mr Haggas and do as much as I can – and learn from him because, who knows, someday I might want to be a trainer.

“I’m just delighted to be given the opportunity to ride out and we’ll take things one step at a time.”

Warren Gatland has called up uncapped back-row forward Taine Plumtree to Wales’ World Cup training squad for a two-week camp in Switzerland.

Plumtree is part of a group that has travelled to Fiesch in the Swiss Alps, the Welsh Rugby Union said.

The 23-year-old was born in Swansea and is the son of former Ireland, Japan and New Zealand assistant coach John Plumtree.

A New Zealand Under-20 international, he has played Super Rugby for the Auckland-based Blues and will link up with the Scarlets next season.

Wales head coach Gatland has seen his back-row options hit by Justin Tipuric retiring from Test rugby and Josh Macleod suffering a shoulder injury.

And Plumtree now has a golden opportunity to showcase World Cup credentials ahead of Gatland announcing his final 33-strong squad next month.

Carlos Alcaraz emerging as a contender for Novak Djokovic's world number-one crown leaves tennis "in good hands" after Roger Federer and Rafael Nadal's impact lessened.

That was the message from two-time major finalist Mark Philippoussis, who believes Alcaraz has what it takes to hold off Djokovic in the battle for the men's top spot.

Alcaraz triumphed at The Queen's Club on Sunday to move back to the top of the ATP rankings, with the 20-year-old seeing himself as a favourite to win at Wimbledon.

Jeremy Chardy will be Alcaraz's first opponent at the grass-court major on Tuesday and former player-turned-coach Philippoussis believes the Spanish youngster has all the skills to down Djokovic.

Philippoussis told Stats Perform: "I think the sport is in good hands. He's somebody that has his mind on looking to take over but looking to do it right now and not just wait until Djokovic has gone.

"Djokovic got to number one, Alcaraz took it back just now by winning Queen's, and by him winning Queen's, it just shows where his mind is.

"He's another guy that has been a grand slam winner and number one in the world, he's always looking to improve.

"He's still looking to improve in every way, he's got a great team around him, and he's doing the right things on and off the court.

"He's continuing to try and improve his net game, along with moving to the net more and mixing up with serve and volley on the grass and it is shown by winning Queen's."

Alcaraz and Djokovic have faced off twice so far, with the latter winning at Roland Garros this year after falling foul of the boy wonder in Madrid last year.

Nadal and Federer were long the challengers as tennis' 'Big Three' alongside Djokovic, but with the injuries curtailing their careers Alcaraz's excellence has somewhat filled the void.

Spanish veteran Nadal has not played a singles match since January at the Australian Open, with his troublesome injury record ruling the 37-year-old out of the French Open and Wimbledon.

Nadal is expected to retire next year, and Philippoussis lauded the 22-time major winner for the legacy he will leave behind when that time comes.

"I mean, it speaks for itself. He is so well loved and respected, and then what he's done in tennis, he is one of the all-time greats," Philippoussis added. 

"It is as simple as that, and somebody that tennis will miss, one of those personalities that we will miss greatly but he's definitely paved the way for a lot of generations from behind him to look up to."
