Naomi Osaka's short-term future appears away from the tennis court after the tearful former world number one said she plans to "take a break from playing for a while" following her shock US Open elimination.

Osaka's US Open title defence came to a remarkable end after imploding in Friday's surprise 5-7 7-6 (7-2) 6-4 loss to teenage sensation Leylah Fernandez.

Up a set and serving for the match at 6-5 on Arthur Ashe Stadium, Osaka lost her cool and composure after throwing her racquet three times in an unsuccessful second-set tie-break.

Amid boos in New York, Osaka was also warned after hitting a ball into the crowd and while the four-time major champion tried to dig herself out of a hole, she crashed out in incredible fashion.

It comes following a difficult couple of months due to mental health concerns as a result of "long bouts of depression" since winning the 2018 US Open.

Osaka withdrew from May's French Open having won her first-round match, after she was fined and threatened with further punishment – and possible expulsion from the grand slam – for skipping obligatory media duties.

The Japanese star subsequently pulled out of Wimbledon before returning for the Olympic Games, though she suffered a surprise loss on home soil in Tokyo and was reduced to tears during a news conference in Cincinnati.

During an emotional post-match news conference, Osaka told reporters: "I'm going to say what we said, I think, like, in the hallway. How do I go around saying this?

"I feel like for me recently, like, when I win I don't feel happy. I feel more like a relief. And then when I lose, I feel very sad. I don't think that's normal. I didn't really want to cry.

"I feel like… this is very hard to articulate. I feel like I'm kind of at this point where I'm trying to figure out what I want to do, and I honestly don't know when I'm going to play my next tennis match [tearing up]. Sorry."

Osaka – who was bidding to become the first woman to defend the US Open since Serena Williams in 2014 – added: "I think I'm going to take a break from playing for a while."

Typically reserved and quiet, Osaka was uncharacteristically frustrated on court – the 23-year-old immediately left the court and emerged with a towel over her head before the start of the final set.

On her outburst, Osaka said: "I'm really sorry about that. I'm really sorry about that. I'm not really sure why.

"I was telling myself to be calm, but I feel like maybe there was a boiling point. Like normally I feel like I like challenges. But recently I feel very anxious when things don't go my way, and I feel like you can feel that. I'm not really sure why it happens the way it happens now.

"It's basically why. You could kind of see that. I was kind of like a little kid."

Carlos Alcaraz was lost for words after making history in the Spanish teenager's shock five-set upset of world number three Stefanos Tsitsipas at the US Open.

Alcaraz – rated by many as Spain's best young male player since 20-time grand slam champion Rafael Nadal first emerged – sent Tsitsipas packing 6-3 4-6 7-6 (7-2) 0-6 7-6 (7-5) in the third round on Friday.

The 18-year-old Alcaraz became the youngest player to reach the last 16 of the US Open since Americans Michael Chang and Pete Sampras in 1989.

Alcaraz also became the youngest man to beat a top-three opponent at the tournament since the ATP introduced its world ranking system in 1973.

After more than four hours on Arthur Ashe Stadium, Alcaraz told reporters: "I have not words to explain how I feeling right now.

"I just don't know what happened out there in the court. I can't believe that I beat Stefanos Tsitsipas in an epic match.

"For me it's a dream come true."

Amid comparisons with countryman Nadal, Alcaraz added: "Honestly I don't copy any style of a players. I just play my game.

"But if I have to say one player that is similar my game, I think it's [Roger] Federer. I think similar as mine game, trying to be aggressive all the time. I think it's a good similar for me."

After his US Open campaign came to a surprise end, third seed Tsitsipas tipped Alcaraz for future success.

"A hundred percent," Tsitsipas replied when asked if he had a sense of Alcaraz's potential. "I said he can be a contender for Grand Slam titles. He has the game to be there."

"I've never seen someone hit the ball so hard," French Open runner-up Tsitsipas added. "Took time to adjust. Took time to kind of develop my game around his game style.

"It's one of these matches and one of these feelings where, you know, you pick up at some point of the match, you feel like you're in control, and it doesn't really go your way at the end.

"It's kind of bitter, I would say, especially after such an incredible first set by my side, dominating, being just so aggressive, not dwelling on the past. It was a great first set.

"I don't know. I felt like he played the fifth one completely -- the way he played the first set basically, careless, going for every single shot. I have never seen someone play such a good fifth set, honestly."

Naomi Osaka's quest for back-to-back US Open crowns came to a shock end, the defending champion imploding in a remarkable 5-7 7-6 (7-2) 6-4 loss to teenage sensation Leylah Fernandez.

Up a set and 6-5, Osaka had the chance to close out the third-round contest before the four-time major champion suffered an epic meltdown on Arthur Ashe Stadium, where fans booed the titleholder.

Osaka – typically reserved and quiet but in the spotlight amid her mental health concerns after withdrawing from the French Open, having skipped Wimbledon – threw her racquet three times in the unsuccessful second-set tie-break on Friday.

The Japanese star received a warning after hitting a ball into the crowd in the final set and while she tried to dig herself out of a hole, 18-year-old Canadian Fernandez completed a stunning upset in New York.

Fernandez showed no fear in her first career meeting with Osaka, going toe-to-toe against the former world number one.

There were no breaks of serve through nine games – Osaka serving to stay in the set at 5-4 and she did so easily before flicking the switch.

Osaka broke to love in the very next game, reeling off nine successive points to take the opening set.

In the third round of the US Open for the first time and with a 1-2 record against top-10 players, Fernandez was not overawed on the big stage.

Behind her big first serve and powerful baseline hitting, Fernandez ensured the second set followed a similar pattern as Osaka was prevented from racing away with the match.

It appeared as though the second set would go down the same path as the first after Osaka broke for a 6-5 lead.

But Osaka imploded on centre court – after failing to serve out the match, she lost her composure in the tie-break, throwing her racquet on numerous occasions as Fernandez forced a deciding set with ease.

Osaka immediately left the court and emerged with a towel over her head before the start of the final set, however, she still looked off her game, broken in the opener.

Continuing to struggle, Osaka was then given a warning for hitting the ball into the crowd, though she boosted her confidence by holding serve and avoiding falling 3-0 behind.

But Fernandez's sole break point was all she needed, sending the defending champion home, much to the delight of the crowd.

Data slam: Fernandez steps up

Her only top-10 victory came against Belinda Benic at the 2020 Billie Jean Cup, having lost to Elina Svitolina and Sofia Kenin last year. But Fernandez claimed the unlikely scalp of Osaka on Friday. The result also ended Osaka's bid to come the first woman to defending the US Open since Serena Williams in 2014.

Carlos Alcaraz put his name up in lights in New York as the 18-year-old stunned third seed Stefanos Tsitsipas in a massive US Open third-round upset.

Spanish teenager Alcaraz scored an astounding 6-3 4-6 7-6 (7-2) 0-6 7-6 (7-5) victory in a battle lasting four hours, seven minutes inside Arthur Ashe Stadium on Friday.

French Open runner-up Tsitsipas became the biggest casualty of the men's tournament so far as hot prospect Alcaraz showed his mettle on the grand slam stage at Flushing Meadows.

It means Alcaraz, rated by many as Spain's best young male player since Rafael Nadal first emerged, has reached the fourth round of a major for the first time in his career.

He becomes the youngest player to reach the last 16 of the US Open since Americans Michael Chang and Pete Sampras in 1989.

The US Open said the win made Alcaraz the youngest man to beat a top-three opponent at the tournament since the ATP introduced its world ranking system in 1973.

Alcaraz put a dire fourth set behind him and looked to have won the match with a lob at 6-4 in the deciding tie-break, but his ball landed a whisker long.

That meant the players were back on serve, but Alcaraz was unbowed and sealed victory with a scorching forehand winner, announcing himself as a likely superstar of the near future. He struck 61 winners in all.

He will face German qualifier Peter Gojowczyk in the fourth round, with a quarter-final place at stake.

Speaking on court after his win, Alcaraz hailed the supportive New York spectators who were firmly in his corner.

"I think without this crowd I haven't the possibility to win this match," he said. "Thank you to you the crowd for pushing me up in the fifth set

"It has been an incredible feeling for me. This victory means a lot to me. It's the best match of my career, the best win.

"For me to beat Stefanos Tsitsipas is a dream come true for me and to do it here is more special."

LaMarcus Aldridge will make a dramatic comeback to the NBA after doctors cleared him to rejoin the Brooklyn Nets, it was revealed on Friday.

Seven-time All-Star Aldridge announced his immediate retirement in April after experiencing a major health scare.

Aldridge revealed that he played against the Los Angeles Lakers while dealing with an irregular heartbeat – an issue that became worse following the 126-101 defeat for the Nets.

Now he is reported to have agreed a one-year deal worth $2.6million, with the 36-year-old eager to get back into action.

In a statement to ESPN, Aldridge said: "I retired in April based on what I believed was the wisest precautionary decision for my personal health at the time, but further testing and evaluation by several top physicians has convinced the doctors, myself and the Nets that I'm fully cleared and able to return to the rigours of the NBA.

"I loved my brief time with Brooklyn and am excited to rejoin the team in pursuit of a championship."

There was no immediate comment from the Nets, who earlier in the day requested waivers on forward Alize Johnson.

The about-turn in Aldridge's plans was not quite as surprising as his initial announcement that his career was over, with recent reports having suggested it was in the offing.

Aldridge only joined the Nets at the end of March as a free agent, averaging 12.8 points in five games after agreeing a contract buyout with the San Antonio Spurs.

He said at the time of his retirement that, despite doctors dealing effectively with his immediate health concern, the aftermath of the Lakers game "was still one of the scariest things I've experienced".

He added, back in April: "For 15 years, I've put basketball first, and now it is time to put my health and family first."

Aldridge, drafted second in the 2006 draft by the Chicago Bulls, was swiftly traded to the Portland Trail Blazers and had nine seasons in Oregon before moving on to San Antonio.

He has career per-game averages of 19.4 points and 8.2 rebounds, with a game high of 56 points, hitting 352 double-doubles.

He stands 49 points short of reaching 20,000, an early target for when he gets back on the court.

Ian Foster has challenged Jordie Barrett to bring a "calmness" to New Zealand at full-back when they attempt to complete a Bledisloe Cup clean sweep of Australia on Sunday.

The All Blacks racked up a record score against the Wallabies to win the Bledisloe Cup for a 19th successive year at Eden Park last month, winning 57-22.

Head coach Foster has made five changes to his side for the rearranged clash at Optus Stadium, with expectant fathers Sam Whitelock, Aaron Smith and Richie Mo'unga absent.

Barrett has got the nod over Damian McKenzie, while Brad Weber gets his second start at scrum-half and Ardie Savea has been named captain for the rest of the Rugby Championship, with Sam Cane injured.

Foster said: "We've been pretty happy with Damian at the back in terms of his influence in the first-receiver role and some of his decision-making from behind. Jordie we know is a quality player. We get asked a lot of questions decision-making-wise on attack and defence at 15, and that's probably his biggest work-on.

"We know he's a great individual athlete who can do some pretty special things, it's just about bringing that calmness to the back and making sure we have real clarity. There is a nice little battle going there at full-back."

Samu Kerevi returns at inside centre for Australia, while Izack Rodda will make his return from the bench and Folau Fainga'a makes his first start of the year.

AUSTRALIA V NEW ZEALAND

Form

New Zealand showed no mercy as they put Australia to the sword in Auckland last time out.

The Wallabies have fond memories of facing their trans-Tasman rivals at Optus Stadium, having scored their highest points total against the All Blacks two years ago in a 47-26 triumph.

New Zealand have lost only one of their past seven Tests against Australia (W5, D1), that 24-22 loss coming at Suncorp Stadium last November.

Foster's men have scored 50 points or more in four of their five Tests this year. The last time the All Blacks brought up a half-century of points more times in a calendar year was when they did so on five occasions in 2007.

Ones to watch

Kerevi has not played for his country since a heavy defeat to England at the 2019 Rugby World Cup in Japan.

The centre's international career looked to be over when he moved to Japan but he is back on the Test stage as he replaces Matt Toomua.

Explosive powerhouse Kerevi, who will partner Len Ikitau, will be expected to make a big impact in the midfield battle.

Foster's pre-match words will be ringing in the ears of Jordie Barrett as he prepares to start in the 15 shirt.

Barrett has scored 106 points in 27 Tests, including 15 tries, and is capable of tormenting Australia.

NHL stars are set to return to Olympic ice hockey at Beijing next February after being forced to miss the 2018 Winter Games, it was revealed on Friday.

An agreement was struck after months of discussions between the NHL, the International Olympic Committee (IOC) and the International Ice Hockey Federation (IIHF).

At the time of players being barred from competing at PyeongChang three years ago, it was reported the main sticking points were the cost of insuring and transporting players while on Olympic duty.

The International Olympic Committee said, in announcing the return of elite stars from the NHL, that it was "travel costs, television timings in North America, and league scheduling" that had prevented their participation last time out.

Full details of the new deal that will allow NHL stars to travel to China have yet to be disclosed, and players could yet be prevented from travelling if COVID-19 circumstances concern the league.

NHL deputy commissioner Bill Daly said: "We understand how passionately NHL players feel about representing and competing for their countries.

"We are very pleased that we were able to conclude arrangements that will allow them to resume best on best competition on the Olympic stage."

IIHF president Rene Fasel hailed the commitment, saying: "I know that I can speak for hockey fans around the world when I say that we absolutely welcome the decision to bring back best-on-best ice hockey to the Olympics.

"We had many constructive discussions, and a lot of hard work was put into making this happen within the time we set for ourselves, and I want to thank all parties involved for their support and commitment."

Players from the NHL had previously featured at each Games from Nagano 1998 through to Sochi 2014, before their absence was keenly felt in South Korea. The Winter Olympics ice hockey programme in 2022 is due to run from February 3-20, with the NHL having cleared a block in its season to allow for stars to compete.

The NHL and NHL Players' Association (NHLPA) indicated in a statement that any COVID-19 doubts could mean there is a change to their stance further down the line.

The statement read: "The agreement allows for the possibility of a later decision to withdraw in the event evolving COVID conditions are deemed by the NHL/NHLPA to render participation by NHL players to be impractical or unsafe."

With Canada and the United States hamstrung by having to field weakened teams in PyeongChang, it was the Olympic Athletes from Russia team who took gold in the men's final, beating Germany after overtime. Canada won bronze, with the United States exiting in the quarter-finals.

The 2021-22 NHL regular season is due to run from October 12 to April 29.

Primoz Roglic heads into the final weekend of the Vuelta a Espana with a third successive title within touching distance, while Magnus Cort won stage 19 on Friday.

Danish rider Cort, who also triumphed on stages six and 12, was the quickest man in a breakaway, holding off Rui Oliveira and Quinn Simmons to clinch victory in Monforte de Lemos.

EF Education-Nippo team-mate Lawson Craddock powered out to lead the final sprint and though Simmons attacked with 200 metres to go, it was Cort who caught the slipstream to claim a dramatic win by a bike length at the culmination of a 191.2-kilometre stage.

Cort, who won two stages in the 2016 Vuelta and one in 2020, said: "It's amazing, it's a dream now, I really hope I don't wake up. It was not before the last five or six kilometres that I started believing.

"They always kept us close and it was a really hard day. We didn't always work perfect together in the front, we had a few attacks that reduced the size of the group.

"I think everybody had tired legs and it was hard to work together in this hilly terrain but somehow we managed to hang onto it."

Roglic kept his general classification competitors at arm's length as he retained his grasp on La Roja heading into the last two stages, finishing 18 seconds behind the leaders.

Saturday's mountain stage could still cause problems, while Roglic has been hurt by time trials in grand tours before – the 2020 Tour de France was settled in Tadej Pogacar's favour in such a manner – but the Slovenian looks well placed to make it three Vuelta wins in a row.

Roglic's family were on hand to witness him receive the 50th overall leader jersey of his career, and the Olympic gold medallist knows he is on the verge of a remarkable achievement.

"It’s beautiful to have my family here. They are my life and I'm very happy," he said.

"It was a hard day from the start to the finish. A super strong break went away. For us, it was fine, and we could take it easy. But La Vuelta is coming to an end so there aren’t much opportunities left.

"The sprinters' teams pulled with a super hard tempo. It's crazy [that this is my 50th Grand Tour leader’s jersey]. Hopefully I can keep it."

What's next?

Saturday's route is a monster. A 202.2km stage from Sanxenxo to Mos. Castro de Herville takes in five short but difficult climbs after a relatively flat start.

Lewis Hamilton knows Mercedes are "on the back foot" after he broke down in practice at the Dutch Grand Prix on Friday.

Hamilton set the pace in the first session at Zandvoort, but lost power after completing just three laps of an FP2 that was halted by a red flag due to Nikita Mazepin going into the Turn 11 gravel.

The seven-time Formula One world champion, who leads Max Verstappen by only three points in the battle for the title, was not overly concerned by the setback as Mercedes investigated the issue.

Asked if he knew what the cause of the problem was, the Brit replied: “Not yet. I was just in there [the garage], I just lost power, so they just told me to stop, but it’s not the end of the world.

"It's been a beautiful day in terms of weather, it's amazing to see the crowd – there's so many people here – it's good to see people hyped and the first time we’ve see the full, full energy.

"Not full yet, but we’ll probably see it in the next few days – all the energy the Dutch fans bring.

"It's more annoying that we only got like 20 minutes of running with that red flag. It naturally puts us on the back foot, but Valtteri [Bottas] looked like he had a good session so probably tomorrow we can try and fill in, make up for some of the time, hopefully.”

Charles Leclerc was fastest in the second session, but Verstappen believes he could have been top of the timesheets in his homeland if the red flag had not been waved.

Red Bull driver Verstappen, who was fifth-fastest, said: "I don’t think it looks very representative from our side in the short run. My lap was on a used set, and the lap I had to abort I think would have been good enough for first.

"Already after one lap, the tyres do drop off a bit. Nevertheless, we will work on a few things where we were not entirely happy in the short runs. But long run looks competitive, so that is always very important."

David Patten, a three-time Super Bowl champion with the New England Patriots, has died at the age of 47, his agent has confirmed.

Patten played for the Patriots between 2001 and 2004 and won three Championship rings with the franchise.

He had previously played for the Cleveland Browns and the New York Giants and went on to have spells in Washington and New Orleans before returning to Ohio and then New England to round off his career as an offseason and practice squad member.

The former wide receiver, who had been the assistant coach of the Western Carolina Catamounts since 2013, cemented his place in Pats history when he caught Tom Brady's first postseason touchdown pass to put New England 14-3 ahead against the St. Louis Rams in 2002. 

New England went on to win 20-17, with the catch the only one Patten made in the game. It was Brady's first Super Bowl success, and the quarterback went on to become an all-time great, winning the Championship game on seven occasions, most recently with the Tampa Bay Buccaneers earlier this year.

Patten tallied up 4,715 regular-season receiving yards over a 12-year career in the NFL, and 106 for rushing.

On Friday, news of his passing was confirmed by Sam Gordon, who runs the G2 Management agency of which Patten was a client.

"Today, I woke up to the worst news you could hear," Gordon posted on Instagram, alongside a photo of himself and Patten.

"My close friend and childhood hero David Patten passed away suddenly last night.

"Very rarely do people get to call their childhood heroes/favorite players their friends. Or even have them take a chance on you. You blessed with me with that. You blessed me with your belief in me when I was getting my company off of the ground.

"But most important of all, you were there to talk when the stress was too great and I was unsure of myself in my field. Mr Patten. My friend, my hero, the first one to believe in me as a manager/agent. I will miss you every day.

"Thank you David Patten. Thank you so much for your friendship, your inspiration, believing in me and trusting me to be your manager."

Richard Seymour, who was Patten's team-mate during his stint with the Patriots, tweeted: "heartbroken... great man of God… lost for words – David Patten..."

Christian Horner has revealed that Williams and Alfa Romeo have expressed an interest in signing Alex Albon for the 2022 Formula One season.

Albon lost his Red Bull seat to Sergio Perez at the end of last season and was relegated to the role of reserve driver.

With Kimi Raikkonen retiring and George Russell strongly fancied to replace Valtteri Bottas at Mercedes, Albon could be back on the grid next year.

Red Bull boss Horner hopes Albon gets another chance and will help the 25-year-old kickstart his career.

Horner said: "I think Alex, he deserves a seat in Formula One next year and I think there's quite a bit of interest in him for next year and we'll do whatever we can to try and enable that.

"I hope that nothing prevents him from realising one of those opportunities. He's a talented driver; it's subject to George moving. Kimi's retiring – that does open up opportunities – so I am sure it will get resolved over the next week or so.

"We're looking at external teams. Williams and Alfa have both expressed interest and yes, we're keen to see him back racing in Formula One, and hopefully that can get resolved over the next few days."

Horner added: "We’ll be supportive of [Albon] racing elsewhere. I hope that Mercedes don't prevent that from happening. He deserves that chance. So, we're doing our best to help him and we’ll see what happens."

Mercedes team principal Toto Wolff insisted he would not stand in Albon's way of a place on the grid despite their backing of Nyck de Vries, the 2019 Formula Two champion who is vying to make the step up.

"I would never block someone like Alex Albon," said Wolff. "He's a fantastic guy, personality is great, I was personally sad to see him going [in 2020], and if he has a chance in a Formula One car I think that's the right thing to do.

"But equally, maybe Nyck has. So we'll have to look at the open spaces at Alfa and at Williams and try to find a solution."

Richard Cockerill and Anthony Seibold have joined Eddie Jones' England coaching set-up.

Former Leicester Tigers and Edinburgh head coach Cockerill has been appointed as forwards coach and will work alongside Matt Proudfoot.

Australian Seibold takes over as defence coach following John Mitchell's departure for Premiership club Wasps.

Seibold switches codes, with his most recent role being as head coach of NRL side Brisbane Broncos.

England head coach Jones said: "We're two years from the World Cup so we wanted to freshen up our coaching team and get the right people in place for where we want to go – which is to win the World Cup.

"We've added Richard to the team to work with Matt to create a dominant forward pack. He's a former England player, has great coaching experience and comes in as a well-rounded, mature, driven English coach."

Jones said of his compatriot Seibold:  "Anthony is a coach that I have had a relationship with since 2019 and have followed his career closely.

"He is a good coach and thinks deeply about the game. John Mitchell did a great job improving us in defence and Anthony will add further nuances to the good system that he has put into place.

"It's an exciting time for rugby with the new season starting, supporters back in the stadium and the return of the grassroots game this weekend – with the rugby community celebrating being back together at Pitch Up for Rugby events around the country. We're looking forward to getting the squad back together and growing this England team."
