Coco Gauff dispatched Zhang Shuai in straight sets to become the youngest US Open quarter-finalist in 13 years.

The 18-year-old American fan favourite won 7-5 7-5 on Sunday, sealing her place in the last eight.

Gauff's victory makes her the youngest player to have reached the quarters at Flushing Meadows since Melanie Oudin in 2009.

Oudin, another American, was 17 at the time, and lost her last-eight tie to eventual runner-up Caroline Wozniacki.

Caroline Garcia is next up for Gauff, who will face either Ons Jabeur or Ajla Tomljanovic should she overcome the US Open quarter-final debutant.

Australia's Tomljanovic followed up her defeat of Serena Williams with a 7-6 (10-8) 6-1 win over Liudmila Samsonova, snapping the Russian's 13-match winning streak and reaching her second career grand slam quarter-final in the process.

World number five Jabeur, meanwhile, made history by becoming the first North African woman to make the US Open quarter-finals in the Open Era.

She is the third woman from the African continent to do so, with South Africans Maryna Godwin (1968) and Amanda Coetzer (1994, 1996 and 1998) having previously achieved the feat. Jabeur defeated Veronika Kudermetova 7-6 (7-1) 6-4.

Los Angeles Rams quarterback Matthew Stafford says there are "no limitations" on his right elbow ahead of the NFL season opener against the Buffalo Bills on Thursday.

The 34-year-old played through the pain as he helped the Rams to victory at Super Bowl LVI against the Cincinnati Bengals earlier this year.

Stafford required a mid-term injection to continue and did not throw during workouts in the spring, with a specific throwing schedule during the Rams' training camp.

But he has revealed he is ready for the new campaign, and says there will be nothing to hold him back, stating: "I feel good. I'm ready to go, no limitations.

"I feel great. I'm ready to go play. [You] can always be better, can always try to feel like [you're] 21 again. But no, I feel really good. I feel like I can make every throw."

Rams coach Sean McVay echoed Stafford's comments, adding: "He's throwing the ball excellent. He feels good. Everyting that I'm seeing is reflective of everything he's saying to me."

Stafford will be looking for another strong regular season in his second year with the Rams, after throwing 41 touchdowns prior to last season's playoffs, the joint-best of his career to date (also 41 with the Detroit Lions in 2011).

Nick Kyrgios took the opportunity to discuss the low points of his career after his victory over Daniil Medvedev, admitting he never thought he would have the chance to return to his best form.

Kyrgios conceded just one set to Medvedev in the 7-6 (13-11) 3-6 6-3 6-2 triumph at the US Open on Sunday.

It appeared during the first set tiebreaker that he was on the verge of one of his famous meltdowns, with a couple of racket slams and plenty of abuse towards his own box, but he steadied and fought back after a poor second frame.

Speaking to the media after the match, Kyrgios admitted the tiebreaker was do-or-die, saying: "I feel like if he'd got that first set, it was going to be pretty much an impossible task for me to come back and win."

This year's Wimbledon runner-up was humble and respectful when discussing the talent of Medvedev, and despite his muted celebration, highlighted what a big deal it is for him to perform well under the bright lights in New York.

"I didn't over-celebrate. It's only the fourth round, I've got quarter-finals [next]," Kyrgios said. "But it was an amazing experience obviously taking down the number one player in the world on Arthur Ashe Stadium.

"I don't really like to celebrate too much after that because I know that if I played him nine more times, he's probably getting on top of me the majority of the time.

"I hadn't won a match on Ashe before this week, now I've won two against two quality opponents, and I feel like I've been able to showcase [my talent].

"There's a lot of celebrities here, a lot of important people here watching. I wanted to get on that court and show them I am able to put my head down and play and win these big matches.

"For the tennis world I think it's important as well. People were really starting to doubt my ability to pull out matches like this at majors. I'm really proud of myself honestly because it hasn't been easy dealing with all the criticism."

Kyrgios continued to discuss how he feels he is perceived by the public and the media, saying it was more a feeling of relief than ecstasy when he finished the job.

"I feel like I'm more just proud of the way that I've bounced back after everything, honestly," he said. "I've been in some really tough situations mentally, and in some really scary places.

"Obviously if you look at it on paper, I probably wasn't expected to win that match. Maybe take a set or two if I'm lucky, give the people a show.

"It's a great win, but I come off the court and I'm just almost relieved that it's over because there's just so much pressure every time I go out on court, so much expectation, so much unpredictability of what I can do.

"I just sit there in the locker room after and I'm just super proud of the performance, because there was really a time where I didn't think I was capable of producing and doing this any more.

"I guess I'm just more relieved, and I'm super proud."

Nick Kyrgios is through to the quarter-final after a terrific 7-6 (11-13) 3-6 6-3 6-2 win over world number one and reigning US Open champion Daniil Medvedev.

It was a match that had all of the usual Kyrgios antics as he seemed to lose his cool during the first set tiebreaker, slamming his racket multiple times while repeatedly yelling at members of his entourage.

But he was able to work his way through it, saving three set points, before sealing the opening frame in 64 minutes with his fourth set point. Kyrgios relied on his dominant serve and limiting his errors, with just one double fault and 11 unforced errors with 21 winners.

The momentum from winning the set kept Kyrgios from spiralling mentally, but he became sloppy in the second, committing four double faults with only three aces, and he had 12 unforced errors with seven winners. It was the only set he had more than one double fault and more unforced errors than winners.

Zverev's ability to return in the second set was the difference, lifting his return point success rate from 33 per cent in the opener to 48 per cent to break twice and even up the match.

It had all the makings of a Kyrgios meltdown, but where he would usually begin to unravel and force desperate power shots to shorten points, he instead settled into the battle and refocused on getting into the net.

After only going to the net five times in the second set, he tripled that in the third, winning nine-of-15 attempts while not allowing a single break point opportunity. Kyrgios only created one break point chance for himself, and he took it with both hands to go up two sets to one.

In the fourth, Kyrgios was able to break again with his first opportunity early on, and with his serve switched on and firing he would only allow one chance for Zverev to break back, but he snuffed it out before going on to secure a second break and the victory.

Of their five career meetings, Kyrgios has now won four, and he will now get the benefit of the number one seed's path through the tournament. Next up, he will face 27th seed Karen Khachanov in the quarter-final as he searches for his first career grand slam title.

Data Slam: Kyrgios accomplishes feat not seen since 1987

Kyrgios is the first player since 1987 to defeat the world number one twice in the same year, with Australian compatriot Pat Cash the last to do it.

It is also the first time an Australian has defeated a world number one in a grand slam since Kyrgios himself, back in 2014 as a 19-year-old against Rafael Nadal at Wimbledon.

Fan favourite Coco Gauff said the reception she has received in New York is different to anything she has experienced before after defeating Zhang Shuai 7-5 7-5 on Sunday.

In a closely contested battle, Gauff was just a little too good, winning 52 per cent (91-of-176) of the total points, while creating 11 break point opportunities compared to nine for Zhang.

It continues a terrific run of form for the 18-year-old, who will break into the top 10 of the world rankings for the first time when it updates this coming week.

Speaking to the media after advancing to the quarter-finals, Gauff compared the atmosphere inside Arthur Ashe Stadium – where she has played every match this tournament – to an NBA game.

"It's way different [to a normal tennis crowd]," she said. "On the 6-5 changeover, people were saying 'let's go, Coco' – I was literally trying not to smile. 

"I was, like, I've got to stay in the zone. Inside I was trying my hardest not to smile. This is a surreal moment for me – on Arthur Ashe Stadium and people are chanting my game. I feel like I'm at an NBA game.

"That's a special thing about tennis. When you go to a football game or an NBA game, people are chanting the team's name. That's great as a player. 

"For you to have the whole crowd chanting your name specifically is something I won't take for granted."

When asked if the incredible attention she has received this week has been a distraction, she said it only helps her in the heat of the contest.

"I think it depends on the player – for me though, I just feed off of it," she said. "I think it helps me more. 

"I mean, for some players, they prefer a more chill, relaxed environment. For me, if anyone has seen me play, I like to get pumped up. The New York crowd seems to like it too."

A meeting with the in-form Caroline Garcia is scheduled for the quarter-final, and she said it is no secret that she is one of the hottest players on tour right now.

"I think she's playing the best tennis she's played in a long time," she said. "It's going to be a challenge. 

"When you play these players that are hot, I think it's more of a mental challenge. You just gotta accept she's going to hit some great shots, because I know she will.

"I think my mentality has been great. I played I feel like two similar opponents, Maddie Keys, who can hit some unbelievable shots from the wings. Same with Shuai today. She was hitting some great shots. 

"I think I was doing a good job of accepting it, clapping my hands, moving on to the next point. I think I'm going to have to do that for the next match."

Gauff and Garcia have played twice before, with the American winning both matches against the Frenchwoman.

Another day, another Aaron Judge home run as the New York Yankees slugger wasted no time extending his league-lead in Sunday's 2-1 win away from home against the Tampa Bay Rays.

As the very first batter of the game, on the second pitch, Judge connected on a 450-foot bomb deep over the left-field wall. 

It was his 53rd home run of the season – and his fourth from his past six games – setting a new career-high after totalling 52 in 2017. He is now eight home runs away from Roger Maris' Yankees record of 61 – set 61 years ago, in 1961.

The AL MVP favourite is also now 17 home runs clear of second-placed Kyle Schwarber of the Philadelphia Phillies, who has 36.

Judge's shot would be the only score from the first six innings against the Rays as Yankees starting pitcher Frankie Montas continued to find some form following a rough start to his time in New York since being traded at the deadline from the Oakland Athletics.

Montas pitched five near-perfect innings, giving up one hit and no walks to go with seven strikeouts.

The Yankees were able to add an insurance run in the seventh frame thanks to a sacrifice-fly from Oswaldo Cabrera, and although closing pitcher Clay Holmes did give up a run, he was able to complete the save for his 18th of the season.

With the win, the Yankees now hold a five-game lead over the Rays for the AL East lead, and they are six games behind the Houston Astros in the race for the best record in the American League.

Gallen extends historic scoreless streak

Arizona Diamondbacks starting pitcher Zac Gallen is in the midst of the eighth-longest scoreless streak in MLB history as he pitched another seven shutout innings in a 5-1 win against the Milwaukee Brewers.

It has been 41-and-a-third innings since Gallen has allowed a run, and in the process he has become the fourth pitcher in the modern era to pitch six consecutive games with at least six scoreless innings – joining Don Drysdale (Dodgers, 1968), Orel Hershiser (Dodgers, 1988) and Zack Greinke (Dodgers, 2015). With one more scoreless inning, he will break the Diamondbacks' franchise record.

The 27-year-old now sports an 11-2 record this season with a 2.42 ERA and a 0.92 WHIP, establishing himself as one of the top arms in the league.

Giants walk-off after duelling home runs late

The San Francisco Giants treated their fans to one of the most enjoyable spectacles in sport as they ended their 5-3 win against the Philadelphia Phillies with a walk-off home run.

With the Giants leading 3-0 in the eighth inning – thanks in large part to a terrific 10-strikeout performance from ace Carlos Rodon – Phillies catcher J.T. Realmuto erased the deficit with one swing as he connected on a three-run home run.

Needing a run in the bottom of the ninth to win, after Bryce Johnson got on base, Wilmer Flores was the hero for the night as he launched the game-winner hard and flat over the left-field wall to send the fans home happy.

The New York Yankees will likely be without Andrew Benintendi for several weeks – and possibly the remainder of the season – after manager Aaron Boone revealed that the outfielder suffered a broken bone in his right wrist that will require surgery. 

Benintendi was hurt taking a swing Friday, but the extent of the injury wasn’t known until Boone reported that he broke the hook hamate bone following the Yankees’ 2-1 win over the Tampa Bay Rays on Sunday. 

An appointment with doctors on Monday will help the Yankees get a better idea of how long he’ll be sidelined and when he could possibly return. 

''It's all too early to say right now, obviously,'' Benintendi said. ''We're still trying to learn some more things. That's what it is right now. Just take it day by day at this point right now, I guess.'' 

Acquired from the Kansas City Royals just before the trade deadline, Benintendi got off to a slow start with the Yankees – going 1 for 20 in his first seven games – but is slashing .298/.337/.479 with 12 extra-base hits and 12 runs in 26 games since then. 

He was selected to his first All-Star Game in July and is batting .304 with 51 RBIs and 54 runs in 126 total games this season. 

With Sunday’s win, the first-place Yankees avoided a three-game sweep to the second-place Rays to move five games ahead of them atop the AL East.  

Red Bull are attempting to secure a Formula One licence for IndyCar driver Colton Herta, to allow him to succeed Pierre Gasly in their AlphaTauri team next year.

The Austrian motorsport giants, who boast Max Verstappen and Sergio Perez as the main drivers for their eponymous F1 lead team, face a battle to gain an exemption as the 22-year-old Herta does not have enough points to qualify under the FIA's system.

Gasly, who took AlphaTauri's first win at the 2020 Italian Grand Prix, is wanted by Alpine to succeed Aston Martin-bound Fernando Alonso.

Herta is the preferred replacement, though the task of convincing the FIA – motorsport's world governing body – to allow his move may be a tough challenge

Red Bull advisor Helmut Marko is hopeful of securing a licence, telling SpeedCity Broadcasting on SiriusXM he believes there should be an answer before the Italian Grand Prix next weekend.

"We looked at the regulations, we discussed it with the FIA," Marko said. "So it's nothing unreasonable. He won seven IndyCar races and that's comparable to a grand prix I think, so it would be a shame if he wouldn't get a super-licence."

Herta enjoyed a two-day testing session with McLaren in July, when he said: "It was different from anything I have ever driven before, but it felt pretty seamless."

Red Bull team principal Christian Horner said no departure for Gasly would be sanctioned unless AlphaTauri could secure Herta for next year.

"We just need clarity which will hopefully come sooner rather than later, because it holds a key role in the driver merry-go-round," Horner said, quoted by the BBC.

"If the option is not there, the other triggers will not come into play. He is an exciting talent, a young American guy who has been a stand-out talent in the US.

"It will be very interesting to see how he performs in F1. To have a successful US driver could be very interesting.

"Pierre is doing a good job in AlphaTauri. There would not be a desire to change if there was not an interesting option available."

Dustin Johnson sunk a long-range eagle putt on the first playoff hole in LIV Golf history to secure a victory in Boston on Sunday, defeating Anirban Lahiri and Joaquin Niemann on the extra hole.

Lahiri had the best third round of the playoff participants, posting a six-under 64 to work his way to 15 under, while Johnson shot 65 and Neimann a 66. Neimann came into the day one stroke off Talor Gooch's lead, while Johnson was alone in third place one further back.

In the playoff, which took place on the par-five 18th hole, Lahiri sailed over the back of the green, and Niemann found a fairway bunker, leaving Johnson as the only player to make the green in three and leave himself an eagle putt.

The two-time major winner made sure a second playoff hole was not necessary, bashing in the eagle, which would have sailed at least 10 feet past the hole if it did not hit it dead in the middle.

As well as the $4million prize for winning the event, Johnson and each of his 4 Aces GC teammates – Gooch (13 under), Pat Perez (seven under) and Patrick Reed (three under) –will also take home an extra $750,000 for topping the team standings for the third tournament in a row

It was a packed leaderboard down the home stretch, with Lee Westwood and LIV debutant Cameron Smith also holding a share of the lead with two holes remaining, before late bogeys took them out of the playoff and into a tie for fourth at 14 under.

Gooch, after entering the round in the outright lead, could only muster a one-under 69 as he watched the field race past him on a day with friendly scoring conditions.

Jason Kokrak finished seventh at 12 under, Mexico's Abraham Ancer was alone in eighth at 11 under, and rounding out the top-10 was a three-man tie for ninth at 10 under consisting of Kevin Na, Louis Oosthuizen and Sergio Garcia.

Phil Mickelson finished tied for 40th at two over, and the last-placed Sihwan Kim will take home $120,000 after finishing 16 over, posting rounds of 87, 63 and 76.

Margaret Court does not believe Serena Williams has ever "admired" her and claims the modern game is significantly easier than it was in her own era.

Williams, widely considered one of the greatest sportspeople of all time, stepped away from top-level tennis following defeat to Ajla Tomljanovic in the third round of the US Open.

Although her time on tour now looks to be over, the 40-year-old admitted "you never know" when asked about future appearances, but a U-turn is widely considered to be highly improbable.

Williams is bowing out with 23 grand slam singles wins – one fewer than record holder Court.

Court, 80, is a Pentecostal church pastor now and has been criticised in recent years for comments about race, homosexuality and the transgender community.

She was blunt when asked about her feelings on Williams, telling the Telegraph: "Serena, I've admired her as a player. But I don't think she has ever admired me."

Court won her grand slam singles titles between 1960 and 1973, and the Australian believes players in the modern era have it much easier than she did during her remarkable career.

"I would love to have played in this era; I think it's so much easier," she said. "How I would love to have taken family or friends along with me. But I couldn't, I had to go on my own or with the national team.

"People don't see all that. As amateurs, we had to play every week, because we didn't have any money. Now, they can take off whenever they want, fly back whenever they want.

"We would be away for 10 months. That's why I first retired in 1965, because I used to get homesick. You might be with the odd other person, but it's not like having your family there.

"We didn't have psychologists or coaches with us. It's a whole different world. That's what disappoints me; that players today don't honour the past of the game."

Caroline Garcia has dialled up the aggression and is reaping the rewards as the Frenchwoman emerges as a serious title contender at the US Open.

On Sunday, Garcia moved through to the quarter-finals by beating Alison Riske-Amritraj 6-4 6-1 on Louis Armstrong Stadium.

She has won four matches without dropping a set in the first week of the grand slam in Queens, New York, but that is just the continuation of a sensational hot streak.

Garcia, now 28, has won 30 of her last 34 matches, landing titles in Bad Homburg, Warsaw and Cincinnati along the way.

At the 2011 French Open, ATP superstar Andy Murray was so taken by the 17-year-old Garcia's performance against Maria Sharapova that he predicted: "The girl Sharapova is playing is going to be number one in the world one day."

Perhaps Murray will turn out to be right after all, with that forecast having long hung over Garcia, as well intended as it was at the time.

She reached a peak of number four in 2018 but was down at 79th on the WTA list in late May of this year.

Now she sits 17th and will keep climbing after reaching the last eight at the US Open for the first time.

On a 12-match winning streak at present, Garcia said after sinking the hopes of American Riske-Amritraj: "I'm so excited to be in the quarters of the US Open. It's been a great couple of weeks for me."

She came through qualifying to win the Western and Southern Open in Cincinnati, beating Petra Kvitova in that final after felling three seeds along the way.

Recent wins over Iga Swiatek in Poland and Emma Raducanu at Wimbledon, beating home favourites, have showed Garcia is suddenly fearless.

"I'm really trying to play aggressive, go for my shots, even when I'm tight or even when I don't feel it," she said.

"It's how I improved so much in the last couple of months and I really enjoy playing like that, moving forward, and I'm having fun."

Garcia was not at her most fluent in the first set of Sunday's fourth-round match but improved and finished the contest having hit 30 winners.

She has only played one grand slam quarter-final before, losing to Karolina Pliskova at that stage in the 2017 French Open.

Suddenly, though, she is playing top-five standard tennis again, and Garcia will take some stopping.

"I want to enjoy every single win I have," Garcia said in an on-court interview.

"When you don't have them, you miss them, so I want to enjoy this one and recover and get ready for the big match in the quarter.

"I'm really having fun here in the US. I got a lot of confidence from Cincinnati, really enjoy the good energy in New York."

Max Verstappen has paid credit to his Red Bull team while suggesting his victories should also be attributed to him being an "exceptional driver" after Lewis Hamilton's recent comments.

The Red Bull man claimed another home triumph at the Dutch Grand Prix to move closer to a second successive world drivers' championship after last year's victory over the Briton.

The Dutchman has been the dominant driver in F1 this season with a superb car, and Mercedes racer Hamilton previously paid tribute to the technical staff, led by Adrian Newey, at the rival team.

The latter's praise notably omitted credit for Verstappen, who edged him for the title in controversial circumstances last year, and whose partner's father, former driver Nelson Piquet, was involved in a racism storm over the seven-time world champion earlier this year.

Asked on Hamilton's comments after victory at Circuit Zandvoort, Verstappen acknowledged the efforts of his team to aid his quest, but also reinforced that he plays just as much of a crucial part in his own success.

"A lot of that is down to the team, of course, as it's also how Lewis won his championships," he stated. "That's how it goes in Formula 1.

"Your car is super important, but I think when you're an exceptional driver like Lewis is as well, you make a difference over your team-mate at the time, in very crucial races as well.

"You end up winning a race like that and that is, at the end of the day, what good drivers do. They do make the difference compared to other fast drivers.

"The car is very dominant in Formula 1 but of course between team-mates, only one can win, and that's where you have to make the difference."
