Iga Swiatek survived a major scare as she came from a set and a break down to beat Jule Niemeier and set up a US Open quarter-final with Jessica Pegula.

The world number one looked to be in a real spot of bother against the German ranked 107 places below her, but Niemeier could not maintain her blistering start and Swiatek claimed a 2-6 6-4 6-0 victory.

Swiatek initially looked a shadow of the player who had not lost a set in the first week, with Niemeier's power and unpredictability causing the Pole no end of issues.

Niemeier was immediately a break up and had no problem consolidating before eventually getting another to lead 5-2.

So underwhelming was Swiatek that Niemeier could even afford three double-faults in the final game of the opener as the German impressively took a first-set lead.

After a bathroom break, Swiatek returned with greater purpose but was still lacking ruthlessness; she inexplicably missed a forehand on break point at 1-0 up in the second, and then she stuck a simple volley into the net a few minutes later to find herself a break down.

That was the first of seven breaks in a second set defined by poor serving, but Swiatek was just slightly better than her opponent, with successive breaks giving her the edge in a rollercoaster encounter.

From there, Niemeier barely registered as a threat due to her wastefulness, recording four double-faults and 14 unforced errors to Swiatek's zero and one respectively in the decider as the latter bageled her opponent.

Daniil Medvedev knows he has not performed to the best of his abilities at grand slams this season after his US Open title defence was ended by Nick Kyrgios.

Medvedev, who will also concede his spot at the top of the ATP's world rankings, has only won one of the four finals he has reached in 2022.

His record in the majors is a particular frustration for the 26-year-old. After losing to Rafael Nadal in the Australian Open final, Medvedev has reached the fourth round at Roland Garros and the same stage at Flushing Meadows, while The All England Club's ban on Russian and Belarusian athletes prevented him from competing at Wimbledon.

With Novak Djokovic unable to play in New York due to his COVID-19 vaccination status, Nadal, Carlos Alcaraz or Casper Ruud will become the world number one after the US Open's conclusion on Sunday.

"I mean, now that you say it, I remember it," Medvedev said in a press conference when asked how it felt to give up the number one spot.

"That's not nice because honestly after such a match, when you lose in a grand slam... I'm trying to look good here, but I'm disappointed.

"[I'm] not going to cry in the room, but I'm a little bit disappointed. For a few days I'm going to be just a little bit sad, looking at my phone, my laptop or watching some series.

"Yeah, it was not the first thing on my mind walking after the match, saying, 'Damn, I will not be the world number one anymore' – I actually don't know which place I will be. Probably three or four. I guess Carlos will pass me. I don't know actually.

"But that's motivation, try to do better. Obviously it was the last slam of the year. I didn't do well enough. Didn't win in Australia when I had the chance. Didn't get the chance to play at Wimbledon.

"Roland Garros, lost in the fourth round. Here, fourth round. Yeah, I should do better, should get more points if I want to be world number one again."

Medvedev went down 7-6 (13-11) 3-6 6-3 6-2 to Kyrgios, who has a 4-1 winning record against the Russian.

Asked if he thought it was Wimbledon finalist Kyrgios' best display against him, Medvedev suggested the Australian came close to replicating the form of greats Nadal and Djokovic.

"Yeah, it was a high-level match," he said. "[I] played Novak, Rafa. They all play amazing. Nick played kind of their level, in my opinion.

"He has a little bit different game because he's not a grinder in a way, [but] at the same time he can rally. He's tough to play.

"He has an amazing serve. He plays well, has every shot. It was a really high-level match from him.

"If he plays like this until the end of the tournament, he has all the chances to win it, but he's going to get tough opponents."

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.

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.

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."

Victoria Azarenka says vulnerable young female tennis players are "getting taken advantage of" as she called for improved safeguarding in the sport.

The Belarusian, who sits on an eight-person WTA players council, was speaking after Frenchwoman Fiona Ferro accused her former coach Pierre Bouteyre of rape and sexual assault.

Bouteyre strongly denied the allegations, with his lawyer telling AFP that he "recognises the relationship occurred but denies any coercion."

Speaking after her US Open victory over Petra Martic, Azarenka called for increased protection and says she would have a "very big concern" if she had a daughter who wanted to play professional tennis.

"It's a very sensitive subject because you won't hear those stories unless players come out and tell those stories," Azarenka said. "It happens right and left on the tour, which is unfortunate.

"Our job is to be better at safeguarding. As player council, it's almost like the number one subject to us. Because we see those vulnerable young ladies getting taken advantage of in different situations.

"It's really sad and really makes me emotional because I have a son [and] I don't see that happening so much on the men's tour.

"If I had a daughter, I would have to question would she want to play tennis, that would be a very big concern in that way for me.

"[The] recent story with Fiona Ferro that came out. I don't know how to put it in words sometimes. All you can do is check in on the person and kind of give your hand what I can do, what I can help with.

"I applaud her for being brave. I hope this situation she's gonna come out of it stronger and tennis is not ruined for her because of that. That's I think [a] very, very heavy topic.

"But it's the topic that has to come out more, and I think it's [journalists'] job also to not expose it. It sounds pretty weird when I say that, but do the research, help people to open up more.

"It's hopefully one by one [as we] try to eliminate that type of situation."

Zhang Shuai went winless in her first 14 appearances at major tournaments but has turned her fortunes around as she prepares for a US Open fourth-round clash with Coco Gauff.

The Chinese tennis player was said to be considering retirement in 2015 after 14 unsuccessful attempts at grand slams, though was convinced to keep fighting by friend and fellow competitor Sam Stosur.

Simona Halep at the 2016 Australian Open was the first scalp Zhang claimed at a major before she went on to reach the quarter-finals.

The 33-year-old, who has two grand slams titles in doubles with Stosur, has not looked back from that win over Halep and has made it to the second week at all four majors in 2022.

"This year, I already have three third rounds," Zhang said after her third-round win at the US Open. "Oh my god, I won six matches! Before I couldn't win one match in many, many years. How happy!

"That's why when we meet some players who want to stop or feels sad after the match, I always tell them next match, see how you are better.

"When I started the tour, how bad [were my] results? No one was worse than me. [These girls are] much better than me, right? You guys are still young. Keep trying."

Gauff awaits Zhang in the round-of-16 as the latter searches for a maiden major success and fourth singles title.

World number one Iga Swiatek says she reminds herself that it is impossible to continually play at the level she achieved during her 37-match winning run earlier this year.

Swiatek reached the second week at the US Open for only the second time after Saturday's 6-3 6-4 win over Lauren Davis and has moved into title favouritism, creating a level of perceived pressure.

That comes amid a run of form where the 2020 and 2022 French Open champion has been far from the levels achieved during her 37-match winning streak which ended in July at the hands of Alize Cornet at Wimbledon.

Since then, Swiatek has only won seven of 10 matches. Swiatek's victory over Davis marked the first time since the winning streak that she has managed three straight victories.

The Pole's hard-court form line has not been compelling either but the exit of Serena Williams along with top seeds Anett Kontaveit, Maria Sakkari, Paula Badosa and Simona Halep has thrust her into US Open favouritism.

But the 21-year-old is trying not to put any extra pressure on herself with that in mind, nor re-discovering the form she displayed earlier in the year.

"Honestly I didn't even focus on that cause I still remember how it is to lose," Swiatek told reporters. "After the tournament in Cincinnati [when she lost to Madison Keys in August], I knew like it's not the end of the world that I'm losing in third round.

"It's not like the whole universe changed so right now I'm always going to be in quarter-finals or finals or whatever, win tournaments. I tried just to remind myself that it's kind of normal, that it's impossible to play always on the same level.

"Here I just took it match by match. I wasn't expecting maybe too much because of the losses, so that's good. It's not like I lost confidence or something. I still know anything can happen on these tournaments."

Swiatek admitted she lacked rhythm against Davis, who had led 4-1 in the second set, before the Pole fought back to win the final five games.

The 21-year-old won 21 of the final 25 points of the match, securing her 53rd victory of the 2022 season, closing in on Ash Barty's 57 from 2019.

"It wasn't as smooth as in first and second round," Swiatek said. "I'm pretty happy I made it through and could close it in second set and come back. That was pretty important for me.

"For sure she played totally differently than most of the players, which threw me a little bit off the rhythm. But I'm happy I was fighting till the end."

Rafael Nadal says his third-round win over Richard Gasquet was his best of this year's US Open as he works his way back after the abdominal tear that ended his Wimbledon campaign.

Prior to the US Open, Nadal had only played once since withdrawing from the Wimbledon semi-final against Nick Kyrgios in early July, losing to Borna Coric in Cincinnati.

The second seed got past Rinky Hijikata and Fabio Fognini in four sets in the first two rounds at Flushing Meadows before Saturday's 6-0 6-1 7-5 win over French veteran Richard Gasquet in two hours and 17 minutes.

"My best match in the tournament," Nadal told reporters. "Easy to say that because the other day was tough.

"But important improvement. But I need to keep going. It's a good victory for me. Straight sets for the first time. Third set had been a challenge. He increased the level.

"I went through some difficult moments. That's something that is good that I went through that and saved that moments with a positive feelings. Happy to be in the fourth round, without a doubt."

The victory over Gasquet meant he has progressed to the second week at Flushing Meadows for the 12th time in his career, although he conceded he would need to lift his level to take out the title, starting with Monday's fourth-round match with 22nd seed Frances Tiafoe.

Nadal is gunning for his third major title this calendar year in New York, having triumphed at the Australian Open and French Open.

The 36-year-old's Australian Open success in February came after minimal preparation due to a foot injury, similar to his US Open lead-up due to the abdominal issue.

"I think I played better in Australia than here going to the second week," Nadal said. "But I have zero background in terms of victories and all this stuff.

"Here I played little bit worse than in Australia, without a doubt. But the story of the year and the results on the slams have been incredible, so that helps.

"I don't know the balance, what's better or worse. But all these victories help to be a little bit more confident. It's a moment to increase, to making a step forward."

"Second week against a great player like Frances, I need to be ready to play and to raise my level. I hope to be able to make that happen.

"I know is the right moment to make an improvement if I want to keep having chances to keep going on the tournament."

Top seed Iga Swiatek reached the US Open fourth round for the second time in her career after reeling off the final five games to beat Lauren Davis on Saturday.

The two-time French Open champion, who enjoyed a 37-match winning streak earlier this year, defeated Davis 6-3 6-4 in one hour and 57 minutes.

Swiatek had trailed 3-0 in the second lap but fought back emphatically to seal her passage into the last 16 where she will face either Jule Niemeier or Zheng Qinwen.

The attention in the women's singles has firmly turned to Swiatek, with Serena Williams eliminated along with the second, third and fourth seeds.

The Pole did not disappoint, hitting 25 winners and six aces, albeit with 38 unforced errors and an apparent lack of rhythm.

Swiatek wrapped up the first set in 59 minutes but world number 105 Davis offered a tougher test in the second after breaking in the second game.

The highly favoured Swiatek had to work out to avoid a 4-0 deficit, holding her serve in a 16-point game, but she showed she was back breaking Davis to love to make it 3-4.

Swiatek won 21 of the last 25 points of the match to book her spot in the second week in New York for the second straight year.

Data Slam: Swiatek finding her hard-court groove

The win improved Swiatek's 2022 tally to 53 matches but it also moved her a step closer to becoming the first player since Serena Williams in 2014 to win seven titles in a single year.

Swiatek has not quite reached the same dizzying levels lately since her 37-match winning streak, which was halted in the third round at Wimbledon, with this victory being only her fifth from eight during the hard-court season.

Second seed Rafael Nadal continued his staggering head-to-head domination of Richard Gasquet as he cruised into the fourth round at the US Open with a straight-sets victory on Saturday.

The 22-time major winner was irrepressible across the first two sets before Gasquet rallied in the third, but Nadal triumphed 6-0 6-1 7-5 in two hours and 17 minutes.

The victory means the 2022 Australian Open and French Open champion will face 22nd seed Frances Tiafoe in the fourth round and improves his head-to-head record against Gasquet to 18-0.

Nadal, who had been shaky early against Fabio Fognini last round, was ruthless when it mattered, hitting 35 winners for the match and winning 78 per cent on his first serve.

After dropping the opening sets in his previous two matches against Fognini and Rinky Hijikata, Nadal responded with a flawless first frame that included converting three of six break points.

Gasquet's belief seemed completely gone in the second set, managing no winners, with Nadal in control. The Frenchman ended Nadal's nine-game winning run to loud applause, raising his arms in celebration and probable relief.

Nadal broke early in the third but Gasquet responded to break back, pushing hard in the third set. But the Spaniard's quality shone highlighted by his finesse with a lob helping him claim the decisive break in the 11th game.

Data Slam: Rafa's longevity on show

Saturday's win was Nadal's 30th at night at Arthur Ashe Stadium and took his tally to 22-0 at majors this year, having only withdrawn from Wimbledon due to an abdominal injury. The triumph also saw him progress to the second week at Flushing Meadows for the 12th time in his decorated career, that includes four US Open titles.
