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.

Australia's Nick Kyrgios has now won 15 of his past 16 matches after defeating compatriot Alex de Minaur 6-2 6-3 in the third round of the Canadian Open – with his only loss coming in the Wimbledon final against Novak Djokovic.

Fresh off his first singles title since 2019 when he won last week's Washington Open, Kyrgios collected his ninth consecutive victory in impressive fashion, showing no difficulty in navigating his first-ever matchup against his fellow countryman.

He won the first four games of the match, and snatched a break in the first game of the second set to book his quarter-final against Poland's Hubert Hurkacz.

Hurkacz, the eighth seed, had to come back from a set down to defeat Spain's Albert Ramos-Vinolas 6-7 (6-8) 6-2 7-6 (7-3). He struggled with his serve early, with four double faults in the opening frame, but cleaned it up as the match went on, double-faulting only once in the last two sets.

England's top hope Cameron Norrie suffered a disappointing 6-3 6-4 defeat at the hands of world number nine Felix Auger-Aliassime, but Daniel Evans and Jack Draper made it through to fly the flag.

Evans pulled off an upset win to beat 10th seed Taylor Fritz 7-6 (7-5) 1-6 7-5, and 20-year-old Draper was up a set when 17th seed Gael Monfils retired with an injury at 6-2 0-2.

American Tommy Paul claimed another scalp with his 6-4 6-2 victory against 13th seed Marin Cilic, giving him back-to-back wins against top-15 opponents after emerging triumphant against Carlos Alcaraz in the previous round.

In the final match of the day, Pablo Carreno-Busta beat his third top-30 opponent of the week with a 6-2 6-4 result against Italy's Jannik Sinner, following strong successes against Matteo Berrettini and Holger Rune.

Nick Kyrgios set up a mouth-watering second-round showdown against world number one Daniil Medvedev after defeating Argentina's Sebastian Baez 6-4 6-4 in his opening match of the Canadian Open on Tuesday.

The in-form Kyrgios is coming off his first ATP singles title since 2019 after winning the Washington Open this past week, where he also won the doubles partnered with Jack Sock. 

Against Baez, he served all six of the match's aces to make it through unscathed, and he will now play the top-ranked Russian – who Kyrgios has beaten twice – although he dropped their third meeting at the Australian Open this year.

Dating back to the start of his Wimbledon run, where Kyrgios made his first grand slam final, the Australian has now won 13 of his past 14 matches, with the only loss coming in the Wimbledon final to Novak Djokovic.

Earlier on, 11th seed Matteo Berrettini was the first upset of the day as he went down 6-3 6-2 against Spain's Pablo Carreno-Busta, while fellow Spaniard Pedro Martinez had less success, getting bounced by France's Gael Monfils 7-6 (7-4) 3-6 6-2.

America's Tommy Paul delivered a gut-punch to his neighbours in the Great White North by eliminating Canada's own Vasek Pospisil 6-4 6-4, and his Canadian compatriot Alexis Galarneau also struggled in his 6-4 7-5 loss to Bulgaria's Grigor Dimitrov.

Marin Cilic showed why he is the 13th seed with a strong 6-3 6-2 win in his all-Croatian battle against Borna Coric, and American Maxim Cressy had similar success against Russia's Aslan Karatsev 6-4 6-4.

In a battle of the French it was Adrian Mannarino prevailing 6-3 6-3 against Arthur Rinderknech, and a pair of Englishmen made their way through unscathed as Daniel Evans won a back-and-forth contest against Filip Krajinovic 6-2 1-6 6-0, while Jack Draper returned to his rain-interrupted fixture against Hugo Gaston to finish the job 6-2 6-3.

Alex de Minaur ensured it would be a grim day for the Canadian fans as he eliminated Denis Shapovalov 7-5 7-6 (7-4), before Holger Rune fought off the challenge of Fabio Fognini to emerge a 6-3 7-5 winner.

In the late session, Roberto Bautista-Agut defeated Marcos Giron 7-6 (7-5) 6-3, ninth seed Cameron Norrie needed just over an hour for his straight sets 6-4 6-4 win over Brandon Nakashima, and Andy Murray had no answer for Taylor Fritz as he went down 6-1 6-3.

Yoshihito Nishioka's strong form held up after his runner-up finish at the Washington Open, cruising past Benoit Paire 6-2 6-3, while 25-year-old Botic van de Zanschulp continued his rise up the rankings with a 6-1 7-5 victory over Miomir Kecmanovic.

12th seed Diego Schwartzman needed three sets to navigate the challenge of Alejandro Davidovich Fokina 1-6 6-3 6-4, and Albert Ramos-Vinolas got the better of Belgium's David Goffin 7-6 (7-2) 6-2.

In the final match of the night, world number 10 Hubert Hurkacz responded to adversity in the second set to pull out a 6-3 6-7 (4-7) 6-2 win against Finland's Emil Ruusuvuori.

Nick Kyrgios capped off a terrific week at the Washington Open by beating Yoshihito Nishioka 6-4 6-3 in the singles final, before combining with Jack Sock to also win the doubles 7-5 6-4 against the team of Ivan Dodig and Austin Krajicek.

In the singles, Kyrgios' serve was overpowering against his Japanese opponent, winning 76 per cent (38-of-50) of his points on serve, and saving the only break point opportunity he faced, which came early in the opening set.

His return game was also sharp, collecting breaks of serve in the first game of each set to snatch all the momentum and keep Nishioka on the back foot and chasing all day.

Kyrgios finished with 12 aces to Nishioka's three, and finished the match just like he started it with a break of serve.

It caps off a tournament where he dropped only one set in his six matches – against Frances Tiafoe in the quarter-final – to win his first singles title since this same event back in 2019.

Just a few hours later, Kyrgios was back on the court with Sock contesting the doubles final, with the pair saving both break points they faced. 

After an even start, Kyrgios and Sock broke late in the first set, and then struck again to break in the opening game of the second set, going on to serve things out comfortably, never allowing Dodig and Krajicek to even reach deuce against their serve.

In doing so, Kyrgios became the first player to ever sweep both the singles and doubles in Washington.

He only had one doubles title before this season – back at the Lyon Open in 2018, also partnered with Sock – but Kyrgios has now won three in the past eight months, emerging triumphant with fellow Australian Thanasi Kokkinakis at both the Australian Open and last month's Atlanta Open.

World number one Daniil Medvedev strolled to victory for his first title of the year at the Los Cabos Open with a 7-5 6-0 demolition of reigning champion Cameron Norrie on Saturday.

The Russian, returning to hard-court tennis in Mexico this week ahead of his US Open title defence, pulled away after an injury timeout late in the first set to comfortably triumph against the 12th-ranked Briton.

Medvedev won every game after the timeout, taken for treatment on a hand issue, after scores were locked at 5-5, with both players having broken serve in the first set.

The third-seeded defending champion had no answers in a lopsided second set which only lasted 26 minutes.

This year's Australian Open runner-up, playing in his fourth final of the season, sent down 5-0 aces and converted six of 10 break points for the match to secure his 14th career title. He was exceptional on serve, with a 67 per cent first-serve win percentage.

The triumph capped an excellent week for Medvedev, who did not drop a set across five wins.

"Every match was very good, but the final match is always special," Medvedev said on court after the match. "It's always a high-level match and I'm really happy I managed to show some good levels and play some good shots."

Wimbledon finalist Nick Kyrgios will take on unseeded Japanese Yoshihito Nishioka in the Washington Open final on Sunday after maintaining his unblemished record at this year's event with a 7-6 6-3 victory over Mikael Ymer on Saturday.

Kyrgios, who won in Washington DC in 2019, had played twice on Friday following rain delays on Thursday but found his passage through with 10 aces including one on match point to secure victory in one hour and 34 minutes.

"I didn’t play anywhere near my best tennis today," Kyrgios said. "I served pretty solid, but from the back of the court I didn’t play well at all. I'm just happy to be in the final once again."

Kyrgios is yet to drop serve throughout this year's tournament and has knocked off seeds Francis Tiafoe, Reilly Opelka and Tommy Paul along the way.

The Australian will take on Nishioka who stunned top seed Andrey Rublev 6-3 6-4 in one hour and 20 minutes to secure a spot in his third career final, beating a top 10 opponent for the third time in his career.

Rublev blasted 21-8 winners but also hit 31-14 unforced errors, with the Japanese's consistency proving enough for victory.

Nick Kyrgios started his Friday by finishing off his third-round win against Reilly Opelka, and his business was not finished until after 1am local time when he defeated Frances Tiafoe 6-7 (5-7) 7-6 (14-12) 6-2 in the quarter-final.

Due to length rain delays on Thursday, Kyrgios was one of five players forced to abandon their matches and return to finish them first thing on Friday, with Kyrgios and Russia's Andrey Rublev the only two to successfully navigate both.

Tiafoe defeated Botic van de Zandschulp 4-6 6-2 6-3 in the morning, but Kyrgios' ability to keep his service games short was a decisive factor, winning the ace count 35-14 and not conceding a single break all match.

Rublev had to deal with Maxime Cressy in the morning, winning 6-4 7-6 (10-8), setting up a quarter-final later at night against J.J. Wolf after the American defeated Holger Rune 7-5 4-6 6-3.

Rublev made his second match look far easier, cruising through 6-2 6-3 to earn a semi-final against Japan's Yoshihito Nishioka after he needed over three-and-a-half hours to beat Daniel Evans 7-6 (7-5) 4-6 7-5.

In an all-unseeded semi-final, Kyrgios will play Sweden's Mikael Ymer, who fought his way past Sebastian Korda 6-2 5-7 6-3 after the American beat Bulgaria's Grigor Dimitrov 4-6 6-1 6-2 earlier in the day.

Meanwhile, down in Mexico at the Los Cabos Open, Daniil Medvedev earned his spot in the final by defeating Serbia's Miomir Kecmanovic 7-6 (7-0) 6-1.

Medvedev will play England's Cameron Norrie for the title after he prevailed in arguably the match of the tournament against top-10 talent Felix Auger-Aliassime 6-4 3-6 6-3.

Daniil Medvedev showed on Thursday why he is the top overall seed at the Los Cabos Open, comfortably handling the challenge of Ricardas Berankis in a 6-2 6-2 win.

The world number one gave Berankis no avenues into the match, winning 48 per cent (27-of-56) of his total return points, while also converting 88 per cent (21-of-24) of his own successful first serves into points.

Medvedev will meet Serbia's Miomir Kecmanovic in the semi-final after he pulled off an impressive 6-2 6-4 victory against American Brandon Nakashima.

Kecmanovic's ability to serve his way out of trouble was the deciding factor, saving four of five break-point opportunities, while Nakashima could only save six out of 10.

Canada's Felix Auger-Aliassime booked his spot in the second semi-final after defeating America's Steve Johnson 6-4 7-6 (7-3).

The 22-year-old winner – who now sits ninth in the world rankings – served up 17 aces in the contest, while Johnson, who is usually known for his serve, could only muster four.

Cameron Norrie was a straights-sets winner over Radu Albot, although he needed a second-set tie-break to get the job done in a 6-3 7-6 (7-4) triumph.

Meanwhile, Norrie's British compatriot Daniel Evans won a war of attrition against American Taylor Fritz at the Washington Open, pulling ahead 3-6 7-6 (8-6) 4-1 before the heavy favourite retired due to the oppressive conditions.

With rising temperatures, combined with spots of rain, the humidity threatened to claim a number of scalps as multiple players in Thursday's action took extended medical timeouts, before a serious downpour halted the rest of play.

The only other matches to reach their conclusion were Yoshihito Nishioka's 7-6 (7-2) 7-6 (7-1) win against Karen Khachanov, and a 6-3 6-7 (3-7) 6-4 triumph for Sweden's Mikael Ymer against Finland's Emil Ruusuvuori.

When play resumes, Nick Kyrgios will look to finish off Reilly Opelka after reaching the rain with a 7-6 (7-1) 2-1 lead, and Grigor Dimitrov won his first set 6-4 against Sebastian Korda.

Botic van de Zandschulp was the beneficiary of the break against Frances Tiafoe, winning the first set 6-4 before slowing down in a big way to drop the second 6-2, but he will get a chance to recharge his batteries before the decider.

Second seed Hubert Hurkacz was a shock second-round casualty from the Citi Open on Wednesday after a straight-sets defeat to Emil Ruusuvuori.

World number 46 Ruusuvuori triumphed 6-4 7-6 (7-3) in one hour and 43 minutes to book a quarter-final spot.

Hurkacz, who is ranked 11th in the world and reached last year's Wimbledon semi-finals, fought hard but failed to capitalise on four break points throughout the match.

"He had an early break point, but then I was able to keep that service game and give myself a chance to break him and I was able to use it and then just try to keep my own serve," Ruusuvuori said.

"I just tried to hang in there and tried to stay as tough as [I] can."

Wimbledon runner-up Nick Kyrgios defeated 14th seed Tommy Paul 6-3 6-4 in one hour and 25 minutes.

The Australian hit 29-21 winners, with the majority coming from his serve and forehand, sending down 15 aces, winning 84 per cent on his first serve.

Kyrgios, who broke Paul in his opening service game, converted three of four break points for the match, while the American failed to capitalise on any of his four.

Sixth seed Denis Shapovalov was bundled out in the second round by American wildcard J.J. Wolf 6-2 6-7 (5-7) 6-3 in a major upset.

Third seed Taylor Fritz avoided an early exit with a 6-4 6-4 win over Australian Alexei Popyrin in one hour and 11 minutes, while fourth seed Reilly Opelka came from a set down to defeat Denis Kudla 6-7 (6-8) 6-4 6-4 in just over two hours. Opelka sent down 28 aces across the match.

Fifth seed Grigor Dimitrov got past Adrian Mannarino 6-1 3-6 7-5 and ninth seed Holger Rune brushed off Benoit Paire 6-3 6-2.

Francis Tiafoe defeated Christopher Eubanks 6-3 7-6 (7-2), while 13th seed Maxime Cressy fought back from an early deficit to get past Jack Sock 4-6 6-4 6-0 to set up a third-round clash with top seed Andrey Rublev.

There were defeats for 11th seed Alex de Minaur to Yoshihito Nishioka 3-6 7-6 (8-6) 6-2, 12th seed Sebastian Baez against Sebastian Korda 6-1 6-4 and 15th seed Aslan Karatsev against Andy Murray's first-round conqueror Mikael Ymer 6-4 3-6 6-4.

At the Los Cabos Open in Mexico, second seed Felix Auger-Aliassime had no troubles against local Juan Alejandro Hernandez Serrano, winning 6-3 7-5.

American sixth seed Brandon Nakashima also progressed into the quarter-finals with a 6-3 6-3 win over Max Purcell, while Miomir Kecmanovic beat Jordan Thompson 6-4 6-2.
