Karen Khachanov reached a grand slam semi-final for the first time as he ended Nick Kyrgios' US Open run in a five-set three-and-a-half-hour epic on Tuesday evening.

The 27th-seeded Russian, who had fallen in the quarters at the 2019 French Open and 2021 Wimbledon Championships, prevailed 7-5 4-6 7-5 6-7 (3-7) 6-4 over the Australian 23rd seed to set up a semi-final date with fifth seed Casper Ruud.

The result ended the run of Kyrgios who had won the most matches on the ATP Tour since losing July's Wimbledon final to Novak Djokovic. Kyrgios had taken out reigning champion and top seed Daniil Medvedev in the fourth round.

The 26-year-old Russian broke Kyrgios' serve in the 12th game of the first set with an exquisite lob clinching the frame where the Australian's second serve let him down.

Kyrgios responded to win the second set, despite a medical timeout for treatment on his left leg after exclaiming "I can't walk", breaking the Russian early and hitting 12-5 winners.

Khachanov claimed the third set in similar circumstances to the first, with Kyrgios failing to hold his serve in the 12th game, this time producing unforced errors in the key moments.

The two players traded breaks early in the fourth set but Kyrgios would force a fifth set after a dominant tie-break where he converted his second set point.

The Russian got an early break in the fifth set, while Kyrgios failed to convert break points in Khachanov's next two service games and he would not recover.

Data Slam: Khachanov cool under pressure

Little split these two players in an extremely tight quarter-final, with 31-30 aces edged by Kyrgios, but many of Khachanov's came at crucial moments under pressure.

Kyrgios' flamboyance and shot-making ability was on show, but his inability to convert break points, along with 58 unforced errors, ultimately proved the difference, taking two of nine.

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."

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.

Nick Kyrgios believes no other player will be able to emulate the career Serena Williams has enjoyed, after the grand slam great confirmed her retirement.

Williams went down 7-5 6-7 (4-7) 6-1 to Ajla Tomljanovic – Kyrgios' former partner – on Friday in the third round of the US Open.

That brought an end to her playing career, though the 40-year-old suggested she would leave the door open for a potential return.

Kyrgios, who defeated J.J. Wolf to set up a contest with reigning men's champion Daniil Medvedev, is in awe of what Williams has achieved, as he ranked the 23-time grand slam champion alongside Rafael Nadal, Roger Federer and Novak Djokovic.

"She's had a career that I don’t think no one else will emulate," Kyrgios said.

"You've got a couple on the men’s side who are trying to catch her in grand slams, but Nadal, Serena, Federer, Novak, these are once in a generation athletes – I wouldn't even put myself in the same category, ever.

"It's a special moment for her, she played extremely well, she won two matches and nearly got on top [against Tomljanovic], it's a hell of a way to go out.

"I just appreciate what she's done and I'm sure everyone in this building does as well."

After beating Wu Yibing, world number one Medvedev said of Williams: "That was a crazy match, it was close to being three hours.

"It's definitely a pity that she lost. If it's the last match of her career, it was definitely an amazing match and she was really close to winning.

"Ajla played at a great level, it was not easy against the crowd and it was a high-level match."

Williams bows out with the most grand slam wins in the Open Era of any player, male or female.

Daniil Medvedev has described both himself and US Open fourth-round opponent Nick Kyrgios as "electric", but says the pair share more "respect" than friendship.

The world number one will continue his men's single title defence against the Australian in the last 16 at Flushing Meadows after a 6-4 6-2 6-2 Win over China's Wu Yibing.

The pair are set to meet for the fifth time on the ATP Tour, with Kyrgios holding an impressive 3-1 record over the Russian in their previous four encounters, including in the final of the 2019 Citi Open.

But Medvedev defeated the former on home turf at the Australian Open earlier this year, in arguably the biggest clash between the duo.

Speaking ahead of the pair's encounter, Medvedev stressed he does not see the pair as friends, but he has strong admiration for his opponent's game and is impressed at how he has revived his fortunes this year.

"I don't think we are friends," he added. "I feel like we respect each other a lot. We are both quite electric. You never know what's going to happen in the future

"Nick is a little bit different from other tennis players on the court. That's his choice. That's his life. I'm not the one to judge. I feel a lot of respect for him."

Asked if he is surprised at Kyrgios' improved form following a first grand slam final this year at Wimbledon, Medvedev added: "To be honest, yes.

"We all knew that he's capable of doing big things. We always knew on [his] day, he is capable of beating anyone.He [has] proved it many times, against the biggest players in the world."

Kyrgios, meanwhile, is relishing another battle on a big occasion, adding that his attempts to seize victory against the odds of public opinion allow him to "thrive".

"You want to be in those moments," he said. "I want to be playing on the biggest stadiums in the world in front of millions of people broadcasted globally. That's where I want to be. That is why I work hard.

"It makes it even sweeter. I know a lot of people don't want me to succeed. I know a lot of people hate my game, the way I do things, the way I go about it. I always thrive on it. I never want to forget all the things people say.

"I always carry this chip on my shoulder. Win or lose, I'm proud of how far I've come. I think that's where every tennis player wants to be, playing the best players in the world in the best stadiums in the world."

World number one Daniil Medvedev was levels above his third-round opponent Yibing Wu on Friday, defeating him 6-4 6-2 6-2 to set up a highly anticipated clash with Nick Kyrgios in his next match.

While Medvedev had the clear power advantage – finishing with 10 more winners and 11 more aces – he also allowed Wu to beat himself, with 18 unforced errors and three winners in the opening set.

Despite his early wastefulness, Wu still created six break point opportunities in the opening set, but could only capitalise on one. It would be his last break of the match as Medvedev tightened the screws down the stretch.

The Russian took the first four matches of the second set to take away any hope Wu had of fighting back into the contest, and in the third set Medvedev's serve really hit top gear.

He faced no break point opportunities in the final frame as he converted over 70 per cent of his points on both first serves (13-of-18) and second serves (eight-of-11), while Wu's errors returned, with 15 and just four winners.

Against Kyrgios next, Medvedev will be looking for his second win against the Australian in their fifth meeting. In their two matches this year – and their only two since 2019 – Medvedev won in four sets at the Australian Open, before Kyrgios got one back at the Canadian Open.

Nick Kyrgios was far too good J.J. Wolf in the third round of the US Open on Friday, not having his serve broken a single time in the 6-4 6-2 6-3 victory.

Kyrgios dominated the match with his serve, racking up 21 aces to Wolf's five, and of the seven break point opportunities the Australian allowed, he saved all seven.

His return game was sharp as well, creating 11 break points and converting five, and he used it to break away in the second set, rattling off five consecutive games to comfortably go up two sets to love.

The third set was more competitive as Kyrgios had a pair of double faults, and more unforced errors (17) than winners (16), but he ultimately had too much firepower for the 23-year-old American.

After coming back from a love-40 deficit, saving four break points in the game, Kyrgios put the finishing touches on the straight sets win with another break of serve to seal it.

With the win, he books his spot in the fourth round, where he will meet world number one Daniil Medvedev.

Kyrgios has won three of the four career meetings between the pair, including their most recent fixture at the Canadian Open.

Nick Kyrgios has complained of the smell of marijuana during his second-round US Open victory over Benjamin Bonzi on Wednesday.

The 2022 Wimbledon finalist made the claim to the chair umpire late in the second set of his hard-fought 7-6 (7-3) 6-4 4-6 6-4 win over the Frenchman at Louis Armstrong Stadium.

The chair umpire remarked that the smell could be coming from the kitchen which Kyrgios retorted with "it was f***ing marijuana".

"People don't know I'm a heavy asthmatic," Kyrgios told reporters after the match.

"When I'm running side to side, I'm struggling to breathe, probably not something I want to be breathing in in between points.

"Yeah, US Open, it's a very different vibe to everywhere else. I feel like Wimbledon was so proper. Australian Open, you kind of expect it there, being an Aussie.

"But here, it's just like noisy. Point in, point out, I can't barely hear. Half the time I can't even hear my team because it's so noisy all the time."

The latter half of Kyrgios' second-round match coincided with major drawcard Serena Williams playing on Arthur Ashe Stadium against second seed Anett Kontaveit.

"Ashe was unbelievably noisy," Kyrgios added. "I couldn't hear anything. Constant jitter. Things going off, sirens.

"In Armstrong today, hearing trains and people. For someone that's struggled to focus in my career, I'm really trying hard to put my head down and play point by point, try to dig myself out of some certain situations.

"It's hard because there's a lot of distractions. Obviously a lot of heckling going on as well. People are saying things. I got to be very careful with what I say these days."

Kyrgios' win means he will take on American J.J. Wolf in the third round on Friday and the 23rd-seed Australian, who won August's Citi Open in Washington DC, said he was feeling motivated and more professional than ever.

"This year's been amazing in so many different ways," he said. "For my tennis, I kind of wanted to almost reinvent myself, get back to the top of the game where I know I belong.

"The Wimbledon final was a turning point I think for me mentally. If I won that match, I don't know where my motivation would have been at. Losing it and being so close, it was really tough for me to kind of swallow that.

"Winning Washington, winning so many matches, I just feel like I thought the pressure would be off me after winning Wimbledon. He's a Wimbledon finalist, he's nearly-over-the-hump-type thing.

"I didn't think I'd be putting this amount of pressure on myself. Every day I come in, I watch what I eat, I try and get sleep. Like every practice session I try and have good intent. I almost don't know who I am anymore, to be honest, because that's not me.

"I feel like I'm really professional right now. I never thought that the Wimbledon final would make me that way. I thought it would be the other way, the reverse, almost a bit lax and a bit chilled with it."

Nick Kyrgios hopes he never has to face Thanasi Kokkinakis again after eliminating his close friend and doubles partner in the opening round of the US Open.

The Wimbledon runner-up began his latest quest for a maiden singles grand slam crown with a routine 6-4 6-4 7-6 (7-4) victory at Arthur Ashe Stadium on Monday.

It marked the first time the pair, who won the doubles event on home soil at the Australian Open in January, have met in a tour-level match.

Kyrgios will also partner Kokkinakis in the US Open doubles, and the 27-year-old did not enjoy facing his compatriot in singles competition.

"When we both saw the draw, it was a nightmare, honestly," Kyrgios said. "We never want to play each other. 

"I've just got so much respect for him. I can't wait to get out there and play doubles with him on the right side of the net.

"We just know each other's games like the back of our hand. We've played together since we were about nine years old. 

"He knows my game well. I know his game extremely well. I just played the bigger points well early on. We're going to play each other, hopefully, never again."

Kyrgios will now take on Benjamin Bonzi, who beat fellow Frenchman Ugo Humbert in five sets to advance at Flushing Meadows.

Nick Kyrgios declared he would welcome an early exit from the US Open ahead of his first-round match against Thanasi Kokkinakis, claiming he remains "exhausted" following his run to the Wimbledon final.

Kyrgios came close to clinching his first grand slam title when he met Novak Djokovic in the Wimbledon final in July, taking the opener but ultimately succumbing to defeat in four sets on Centre Court.

The enigmatic Australian, who has never gone beyond the third round of the US Open, will begin his final major campaign of the year against his compatriot and doubles partner Kokkinakis on Monday.

But the 27-year-old is not enamoured by the prospect of a deep run in New York, revealing he struggles with being away from his homeland while playing on the ATP Tour.

"A big part of me just wants the US Open to be over so I can go home," he said on Sunday.

"It's brutal not being able to have the normality of your own bed or your own family for so long and then you have to deal with all this.

"The media, the fans, the training, the matches, the pressure, especially on my spectrum as well – it's not normal. So it's hard. It's really hard.

"I'm definitely feeling very exhausted. Just after Wimbledon, I didn't even have time to enjoy it.

"Everyone gets to go home on the tour. They get to take a cheeky little flight back home to reset. There's just no other type of tennis player who really understands that [homesickness] apart from the Australians.

"Whether I win or lose, it's going to be the same for me. It's a win-win for me. If I win, it's more money and another great result. If I lose, I get to go home."

Asked what he had gained from his thrilling Wimbledon run, Kyrgios said: "The confidence in myself to be able to do it over two weeks. Staying in a single spot for two to three weeks can be exhausting. 

"To know that I can do that and go about things the right way and take every practice session, every recovery session, the right way, it's confidence in the back of my mind. 

"But also, I'm the type of player that if I had won Wimbledon, I probably wouldn't have played the US Open."

Meanwhile, the US Open is set to mark a final grand slam appearance for legendary 23-time major singles champion Serena Williams, and Kyrgios believes she deserves to be considered the greatest player in the sport's history.

"Obviously it's a very special moment for her. She's probably the greatest of all time," he added.

"Whether or not we see anyone live the career that she has? I don't think that's possible."

A spectator at the Wimbledon final who Nick Kyrgios accused of looking like she had consumed "about 700 drinks" is taking legal action against the Australian.

Polish lawyer Anna Palus was temporarily ejected from Centre Court last month after Kyrgios claimed she was drunk and putting him off during his defeat to Novak Djokovic.

He said to the chair umpire between points: "She's drunk out of her mind in the first row.

"The one who looks like she's had about 700 drinks talking to me in every single point."

Ms Palus has instructed her solicitors, Brett Wilson LLP, to start defamation proceedings against the 27-year-old and she is prepared to take the case to the High Court if there is no "prompt resolution" to the matter.

She said in a statement released by solicitors Brett Wilson LLP: "On Sunday 10 July 2022 I attended the final of the Wimbledon tennis championships with my mother.

"It was an event we had been looking forward to for some time. During the course of the final, Nick Kyrgios made a reckless and entirely baseless allegation against me. 

"Not only did this cause considerable harm on the day, resulting in my temporary removal from the arena, but Mr Kyrgios's false allegation was broadcast to, and read by, millions around the world, causing me and my family very substantial damage and distress.

"I am not litigious, but after much consideration, I have concluded that I have no alternative but to instruct my solicitors Brett Wilson LLP to bring defamation proceedings against Mr Kyrgios in order to clear my name.

"The need to obtain vindication, and to prevent a repetition of the allegation, are the only reasons for taking legal action. Any damages recovered will be donated to charity.

"Given the extant claim, I am unable to comment further on the events of the day in question. I hope that Mr Kyrgios will reflect on the harm he has caused me and my family and offer a prompt resolution to this matter. However, if he is unwilling to do this, I am committed to obtaining vindication in the High Court."

Nick Kyrgios' red-hot form has been halted after going down in three sets to eighth seed Hubert Hurkacz in the quarter-finals of the Canadian Open on Friday.

Hurkacz ran away with victory, triumphing 7-6 (7-4) 6-7 (5-7) 6-1 in one hour and 46 minutes in Montreal.

Wimbledon finalist Kyrgios had come into the encounter fresh from winning 15 of his past 16 matches, including lifting the title at last week's Washington Open. Kyrgios' run had fueled expectations around him at the upcoming US Open.

"Nick has been playing some incredible tennis throughout the past weeks, so it is a pleasure playing against him," Hurkacz said post-match in his on-court interview.

"I started really well. Nick was maybe a little bit injured, which might have hurt his serve. With both of us serving so well, that few per cent can make the difference."

Kyrgios was quick on serve but the 25-year-old Pole eventually ground him down, prevailing in the third set aided by an early break.

That break came after Kyrgios gave up two double faults, leading to the Australian to complain to the umpire about his opponent's mid-match break for a change of clothes.

The Australian was unable to break Hurkacz's serve throughout the match, with the Pole edging the aces count 20-19, while he was also superior on return. Kyrgios had more winners (55-47), but more unforced errors (24-13).

Hurkacz, who will face fourth seed Casper Ruud in the semi-finals, is the only former Masters 1000 champion left in the draw.

Ruud cruised into the last four with a 6-1 6-2 victory over hometown hero Felix Auger-Aliassime who was brushed aside in one hour and 14 minutes.

The Norwegian's win marks his third ATP Masters 1000 semi-final of the season, with the Canadian plagued by 21 unforced errors compared to Ruud's eight.

Unseeded Briton Daniel Evans fought back from a lopsided opening set to knock off Tommy Paul 1-6 6-3 6-4.

Evans will face Spaniard Pablo Carreno Busta after he defeated Jack Draper 7-6 (7-4) 6-1 in just under two hours.
