Another big-serving display from John Isner at Wimbledon means he now has the most ATP Tour aces on record.

Ivo Karlovic – one of only two tennis stars taller than the giant Isner – had set the benchmark with 13,728 across his career, the most since aces were first tracked in 1991.

But Isner has chipped away at that total over the course of this week at the All England Club.

The American's 54 aces in five sets against Enzo Couacaud in the first round made him the first player to pass 50 in a grand slam match since he had last done so versus Steven Johnson at the 2020 US Open.

And there were a further 36 in an epic second-round win over Andy Murray, leaving Isner just four short of matching Karlovic and five away from passing him.

Against Jannik Sinner, in Friday's third round, Isner raced past his target, tallying 12 aces in the first set alone.

It is a record Isner is likely to own for some time, with 43-year-old Karlovic absent from the ATP Tour this year and playing only six main-draw matches in 2021.

Roger Federer is third on the list, way back on 11,478.

Mohamed Salah landed a bumper new contract through to 2025 and vowed to repay Liverpool's belief in him by firing Jurgen Klopp's Reds to more trophies.

Uncertainty over the Egyptian forward's future had lingered for months, with no clear sign of a breakthrough in negotiations between the club and the player's representatives until a deal was announced on Friday.

With Sadio Mane being allowed to leave for Bayern Munich since the end of last season, the importance of securing Salah was ramped up, and now the 30-year-old has confirmed he will stay at Anfield.

He could have walked away at the end of the 2022-23 season on a free transfer, had he not agreed to new terms, but that worrying prospect has been quashed.

With at least three years more to come of his Anfield career, Salah is convinced he and Liverpool can enjoy huge success in that time.

They threatened a quadruple last term before just missing out to Manchester City in the Premier League title race and losing 1-0 to Real Madrid in the Champions League final, having already pouched the FA Cup and EFL Cup.

Salah said of his new deal: "It takes a little bit of time, I think, to renew, but now everything is done so we just need to focus on what’s next.

"I think you can see in the last five or six years the team was always going [upwards]. Last season we were close to winning four, but unfortunately in the last week of the season we lost two trophies.

"I think we are in a good position to fight for everything. We have new signings as well. We just need to keep working hard, have a good vision, be positive and go for everything again."

In an interview for Liverpool's official website, Salah spoke of the departure of Mane to the Bundesliga and the arrival of Uruguayan frontman Darwin Nunez from Benfica, as manager Jurgen Klopp shuffles his pack.

"I'm so excited, I want to play with him," Salah said of Nunez. "He had a good season last season and played well against us home and away [in the Champions League].

"Sadio's leaving, and I'm going to miss him, he had great seasons with the club, so I wish him all the best, and I wish Darwin also all the best to score many goals for us."

Salah had a stellar 2021-22 campaign, finishing level with Tottenham's Son Heung-min in the race to be the Premier League's top scorer, while also managing the most assists in the competition, racking up 13 to finish one ahead of team-mate Trent Alexander-Arnold.

It was the third time that Salah has won the Premier League's Golden Boot, having also been top scorer in the 2017-18 and 2018-19 campaigns.

He won the FWA Footballer of the Year and the PFA Players' Player of the Year awards, and taking all competitions into account finished the campaign with 31 goals and 15 assists in 51 appearances, creating 87 scoring chances.

Across his five-season Liverpool career to date, Salah has managed 118 Premier League goals, at an average of one every 126 minutes, a league-best for players who have played at least 100 games in that time.

Salah had been linked with the likes of Barcelona and Real Madrid, but Friday's announcement means the former Roma and Chelsea forward's stint with Liverpool is far from over, as he prepares for a sixth season with the Reds.

In a message to supporters, Salah said Liverpool would "try to win all the trophies" in the new campaign.

Hugo Ekitike may end up staying at Reims in this transfer window as he waits on a move to Real Madrid or Barcelona.

Newcastle United have long since agreed a deal with Reims for the forward, but the transfer has not progressed further.

Reports have suggested the demands of Ekitike's agent have put off Newcastle, while the 20-year-old has continued to be linked to other clubs.

And Oscar Garcia, the Reims coach, revealed on Friday the player is in no hurry to leave.

Wantaway Reims stars are said to have a July 10 deadline to secure moves, and with purported interest from Madrid subsequently dismissed, Ekitike's short-term future could still be in Ligue 1.

Garcia told a news conference: "He told me that he wanted to stay, but if Real Madrid or Barcelona arrive...

"I feel Hugo is calm. I spoke with him. He will have no problem staying at the club – and neither will I."

Ekitike scored 10 goals and assisted three more in the league last season, contributing a goal involvement every 98 minutes on average.

Attempting only 31 shots, his conversion rate of 32.3 per cent was the second-best among players with 20 or more attempts across Europe, far outperforming his expected goals total of 7.0.

As well as Newcastle and Madrid, Ekitike has been linked with Borussia Dortmund and Paris Saint-Germain.

The San Jose Sharks have fired head coach Bob Boughner after missing out on the playoffs for a third straight season.

Boughner was in the final year of a contract that would have paid him $1.5million in 2022-23.

He was relieved of his duties on Friday along with assistants John Madden, John MacLean and Dan Darrow in another organisational shake-up for the struggling franchise.

The Sharks are also looking for a new general manager after Doug Wilson stepped down in April for health reasons. Wilson, who had served as GM since 2003, had been on medical leave since November, with assistant GM Joe Will handling his duties.

Boughner compiled a 67-85-23 record after replacing Peter DeBoer in December 2019. The Sharks finished 11th in the Western Conference this past season with a 32-27-13 record, and their three straight seasons of missing the playoffs is the longest stretch in the franchise’s 30-year history.

The 51-year-old previously spent two seasons as the Florida Panthers’ head coach, amassing an 80-62-22 record with no playoff berths.

San Jose have reportedly narrowed down a list for Wilson’s successor. Former Sharks players Ray Whitney and Mike Grier, neither of whom have experience as a GM, are believed to be among the finalists, according to Sportsnet Canada.

The Sharks join the Winnipeg Jets as teams with head coaching vacancies.

Beaming Brit Heather Watson got her reward for years of persistence at Wimbledon by reaching round four of a singles grand slam for the first time.

Watson also earned herself a rare day off, after a hectic start to her campaign, by racking up a 7-6 (8-6) 6-2 victory over 21-year-old Slovenian Kaja Juvan.

In singles, Watson is a four-time WTA event winner and this was a 43rd grand slam main-draw appearance, yet she had only reached the third round in a major four times before this campaign.

Watson, who has lost in round one on all 10 of her US Open singles appearances, now has a last-16 match at Wimbledon inked into her diary, achieving at the age of 30 what many thought would come much earlier in her career. Germany's Jule Niemeier awaits Watson, with a quarter-final place on the line.

Guernsey star Watson's previous best Wimbledon singles runs came in 2012, 2015 and 2017, when she was halted by Agnieszka Radwanska, Serena Williams and Victoria Azarenka respectively.

In mixed doubles, she was a champion with Finland's Henri Kontinen in 2016 and a runner-up in 2017, but singles is where it matters most.

This week she has faced Tamara Korpatsch, Wang Qiang and world number 62 Juvan, a kind run compared to previous Wimbledons, and Watson has taken advantage. She has unusually had to play every day so far, however, with her first-round and second-round matches both spanning two days.

A former world number 38, Watson has drifted to 121st in the WTA rankings. She won just five games when well beaten by Juvan at last year's US Open, but this time it was Watson's day.

It was a match she would have fancied, given Juvan had already lost four times this season to players ranked outside the top 100.

Watson said in an on-court BBC interview: "Wow, what an atmosphere. I actually wasn't that nervous, but first time in the fourth round, I'm so happy. I'm not speechless because I'm blabbing on, but I don't know what to say. It means everything."

She has taken inspiration from seeing fellow Britons Katie Boulter, Cameron Norrie and Liam Broady battle through early matches.

"It really helps. I've watched all of their matches," Watson said. "It's really inspiring, and we're all egging each other on."

Mohamed Salah has ended speculation over his future by signing a new long-term contract with Liverpool.

Mohamed Salah has ended speculation over his future by signing a new long-term contract with Liverpool.

The Egypt forward only had a year remaining on his previous deal with the Reds and could have departed as a free agent after the 2022-23 season.

Liverpool on Friday revealed Salah has agreed to extend his successful stay at Anfield until 2025.

The 30-year-old helped the Reds win the FA Cup and EFL Cup last season, while they also reached the Champions League final and finished second in the Premier League.

He finished level with Son Heung-min as the Premier League's top scorer in the 2021-22 campaign, but his Liverpool future appeared to be in the balance as negotiations over a new deal dragged on.

Salah's decision to remain on Merseyside is a huge boost for Jurgen Klopp’s side after the departure of Sadio Mane to Bayern Munich.

He told Liverpool's official website: "I feel great and [I am] excited to win trophies with the club. It’s a happy day for everyone."

Salah scored 31 goals and provided 15 assists in 51 appearances for the Reds last season.

He scored 23 of those goals in the top flight as Liverpool pushed Manchester City all the way in the title race, only missing out on the final day when Pep Guardiola's team came from 2-0 down to beat Aston Villa and regain the trophy.

Salah had been linked with the likes of Barcelona and Real Madrid, but his stint with Liverpool is far from over, as he prepares for a sixth season with the Reds, having arrived from Roma in 2017.

Corentin Tolisso is hopeful that his move from Bayern Munich to Lyon will help secure him a return to the France fold ahead of the World Cup.

The 27-year-old's return to Lyon, with whom he started his career, was confirmed on Friday following the expiration of his Bayern contract. 

Tolisso spent five trophy-laden campaigns at the Allianz Arena, but he started just 12 matches in all competitions in an injury-plagued 2021-22 campaign.

He did not feature for France at all last season, with the most recent of his 28 senior caps coming at last year's rescheduled Euro 2020.

But after completing a move back to Lyon on a five-year deal, Tolisso is targeting a place in Didier Deschamps' squad in time for Qatar 2022.

"I didn't talk with [Deschamps about the decision. It was a personal one, though I talked a lot about it with my agents and my family," he said at a news conference.

"We said it was the best decision for me. The future will tell if I was right or wrong. Lyon is the right club for me to return to the French team and go to the World Cup.

"I am very proud and happy to be back in Lyon. The project seduced me. It's a good thing for me and my personal goal, which is to play in the World Cup."

Tolisso was a member of France's World Cup-winning squad four years ago and also won five Bundesliga titles and the Champions League during his time in Bavaria.

Injuries, including a cruciate ligament rupture that ruled the midfielder out for the majority of the 2018-19 season, restricted him to 118 games in five years with Bayern.

However, the Lyon youth product feels he learned a lot with the German giants and does not believe his injury issues are any longer a concern.

"I learned on both a human and professional level," he said. "I remember the trophies and how we won them. There are many things to remember. 

"I remember a lot of positive things. Of course, there were not only positive things, but that's also part of life, that's how it is. The negative experiences helped me to grow.

"I have gained more maturity and experience; I have learned a lot at Bayern Munich in these five years. I grew and learnt a new system, a new culture, a new mentality.

"As for the injuries, I passed the medical, which is already a good point. It's true that I had problems.

"I previously said that my worries were more psychological and mental than physical, for reasons I won't necessarily reveal today. 

"A lot of things have been going on in my head over the last year that have influenced the large number of injuries I've had. I did a lot of physical preparation. 

"Now I am ready. I passed some [physical] tests yesterday. It went extremely well so everyone can be reassured about my fitness. There will be no problem."

Zion Williamson is set to agree a five-year, $231million rookie max extension with the New Orleans Pelicans.

The imminent deal was reported by The Athletic's Shams Charania on Friday, the second day of NBA free agency.

A number of leading stars were given new deals on Thursday – including Nikola Jokic, Devin Booker and Ja Morant – and Williamson should now join them.

The Pelicans are building an exciting young team, making the playoffs in 2021-22 and taking the number one seed Phoenix Suns to six games despite Williamson's injury absence.

New Orleans could be forgiven for having some concerns about committing such a huge sum to Williamson, though.

The former first overall pick has played only 85 games in three seasons in the NBA – albeit he has averaged 25.7 points and 7.0 rebounds per game.

Williamson has spoken of his desire to commit to the Pelicans, but Charania added this deal was expected to include "protections".

Marseille have confirmed the exit of Jorge Sampaoli as coach, with the Argentine departing Stade Velodrome just under a year and a half after his arrival.

The 62-year-old succeeded Andre Villas-Boas at the helm of the Ligue 1 outfit last March, and guided them to a second-place finish behind champions Paris Saint-Germain in his only full season in charge.

Yet just weeks after earning Champions League qualification, the former Albiceleste boss is on his way after reportedly growing frustrated with a lack of transfer activity and ambition from the club.

"[We] would like to sincerely and warmly thank the work of Jorge Sampaoli," read an official club statement.

"We are satisfied with the progress made and the emotions experienced together, but following a long reflection, the two parties [...] have agreed to put an end to this stage [of their careers].

Club president Pablo Longoria will now begin a search for a successor to Sampaoli, who leaves with 36 wins from 67 games in charge, and with a season still to run on his contract.

DP World Tour chief executive Keith Pelley has hit back at LIV Golf rebels and says sanctions imposed on players were "proportionate and fair".

Lee Westwood and Ian Poulter were among 16 DP World Tour members who were last week fined £100,000 and banned from playing in three events – the first being the Scottish Open next week.

They were sanctioned by the DP World Tour for playing in the inaugural LIV Golf Invitational Series event at Centurion Club without permission last month.

In an open letter, which was addressed to Pelley, published by The Telegraph, the 16 players threatened to take legal action against the DP World Tour if the fines and suspensions were not rescinded.

They also claimed that the DP World Tour is playing "second fiddle" to the PGA Tour in an extended relationship between the two.

Pelley provided a strong response as he refused to back down on Friday.

He said in a statement: "There has been a leak to the media of a letter we received on behalf of a number of LIV Golf players which contains so many inaccuracies that it cannot remain unchallenged.

"Before joining LIV Golf, players knew there would be consequences if they chose money over competition. Many of them at the time understood and accepted that. Indeed, as one player named in the letter said in a media interview earlier this year; 'If they ban me, they ban me.' It is not credible that some are now surprised with the actions we have taken.

"The letter claims that these players 'care deeply' for the DP World Tour. An analysis of the past participation statistics on our Tour in recent years of several of the leading players named suggests otherwise

"One player in particular named in the note has only played six Rolex Series events in the past five years. Another one, only four. I wish many of them had been as keen to play on our Tour then as they seem to be now, based on the fact they have either resigned their membership of the PGA Tour or, if they are still in membership, have been suspended indefinitely.

"Furthermore, given how deeply these players say they care about the DP World Tour, perhaps some of them could have played in Ireland this week in support of our new title sponsor, in particular one player who gave us a signed commitment to play at Mount Juliet.

"With that player currently in action at Pumpkin Ridge, you can imagine the allegation in the letter that we are in the wrong, is hard to accept.

"We also take great exception to an allegation made near the end of the letter which states we are somehow playing 'second fiddle' to the PGA Tour. Nothing could be further from the truth.

"We held a player meeting in Ireland on Tuesday where we outlined in great detail all the many benefits of our expanded relationship with the PGA Tour.

"One of those is an unprecedented ten cards on offer to the PGA Tour, cards that many of the players named in this letter desperately wanted to attain in the early stages of their careers. Why now be critical of those trying to do the same?

"The letter also expresses supposed concern about the future of the DP World Tour. Rest assured no-one should have any worries on that score.

"The DP World Tour is a vibrant, independent and global Tour with increasing and guaranteed prize fund growth over the next five years. We have fantastic tournaments across the year including a host of wonderful national Opens, all played in front of huge crowds, illustrated perfectly by this week's Irish Open.

"Finally, it would not be appropriate for me to comment on any potential legal matters.

"I will simply reiterate that our Members' Regulations which have been in force for more than 30 years, have been accepted by all the players, are there to protect all of our members, and we will use them to take all necessary steps to protect their interests.

"The sanctions for those members who knowingly broke our rules by playing at the Centurion Club without a release are proportionate, fair and, I believe, considered necessary by the majority of our members."

Pat Cummins was delighted with Australia's "brave" approach after they thrashed Sri Lanka by 10 wickets on day three of the first Test.

The tourists took a first-innings lead of 109 at the Galle International Stadium on Friday before bowling Sri Lanka out for only 113.

Nathan Lyon took 4-31 after claiming a five-wicket haul in the first innings, and part-time spinner Travis Head, who had never taken a Test wicket, claimed stunning figures of 4-10 as Sri Lanka folded.

Mitchell Swepson took the other two wickets, and after being set only five runs to take a 1-0 lead in the two-match series, David Warner hit Ramesh Mendis for four and then six inside the first over to seal an emphatic victory.

Australia captain Cummins said: "A couple of new words we're using about our approach is about being proactive and being brave.

"We saw some really clear methods from all the batters. They might have been individually a bit different, but you saw everyone being really proactive and putting pressure back on the bowlers. It's something you'd normally talk about in one-day cricket or T20 cricket. But I think that's the style over here that's needed."

He added: "I think it's part of the environment that we are trying to create. Failure is absolutely okay, as long as you are failing in a way you are happy to be."

The paceman lavished praise on spinner Lyon, who moved into the top 10 on the list of all-time leading Test wicket-takers by taking his tally to 436.

"I wouldn't change Lyon for anyone," Cummins said. "He's gone into the top 10 wicket-takers of all time. You saw him out there. He's unplayable for left or right-handers.

"Sometimes out here, bounce for spinners is spoken about [as] something that's not desirable, but he showed here with that bounce he was unplayable. His stamina as well – you give him the ball from one end and say see you at the end of the day."

Wales coach Wayne Pivac is hoping for a first good night's sleep in almost four months when his side get their tour of South Africa underway this weekend.

The tourists kick off their three-match series against the world champions at Loftus Versfeld Stadium on Saturday in what will be the teams' second meeting since the Springboks won their 2019 Rugby World Cup semi-final encounter.

Armed with several players who partook in the British and Irish Lions' tour to the Southern Hemisphere last year, Pivac will have some experienced heads on hand as he hopes to spring a surprise.

But he admits his time spent masterminding his side's prospects after a dismal start to 2022 means he will only rest soundly when the first game is done and dusted.

"I’ll probably get my first decent night's sleep since the end of the Six Nations," he stated. "That's a fact.

"It just doesn't go away. The thing with coaches and players is you're not happy until you get your next win under your belt. It's been a long time between drinks, and of course there is that memory.

"If you finish on winning the Six Nations then it's quite a nice memory, but losing to Italy has been challenging in terms of the pressure you put on yourself as opposed to the pressure others put on you."

Wales have lost their past three matches and are winless in five away from home, sliding to ninth in the world rankings while South Africa retain top spot.

Pivac is aware his side will be the underdogs, adding: "It's understandable. You've got to look at where the two teams are coming from. They're the world champions, in their own backyard, at altitude.

"It's a tough place for anyone to go, and from the outside looking in, from our last performance, you would write us off.

"The main thing is that we haven't written ourselves off. Some of the players look at it, a lot of them are on social media all the time. It's a fact of the game. I don't mind it at all, because it is just people reporting on the facts.

"If you want to argue, play a bit better. That's where we've got to do our arguing and say that we are better than that, don't write us off and then bang."
