Rafael Nadal shot down Denis Shapovalov's suggestion that he receives special treatment from umpires after an epic Australian Open quarter-final tussle.

Shapovalov fell short of an incredible comeback against the record-chasing Nadal, who prevailed 6-3 6-4 4-6 3-6 6-3 after over four hours of action on Rod Laver Arena.

The match was full of tension, with Shapovalov furious that Nadal escaped a time violation for taking too long between the first and second sets. 

After umpire Carlos Bernardes refused to call time on Nadal's changeover, Shapovalov lost his temper, bursting out: "You guys are all corrupt."

The players subsequently met at the net for a discussion, but Shapovalov was frustrated again when, before the deciding set, Nadal left the court for a medical timeout having struggled with a stomach issue, but then also had a toilet break.

Asked in his post-match news conference if he felt Nadal received preferential treatment, Shapovalov said: "Of course. 100 per cent he does. 100 per cent."

Shapovalov's comments were put to Nadal in the Spaniard's own media conference.

"No. Not in that case, no, no," Nadal responded.

"I really believe that on the court you don't deserve better treatment than the others. I really don't want it and I don't feel I have it.

"Without a doubt, even as everybody knows, I have a huge respect for Carlos and I think he's a great umpire. Is it not the case that he was always hard with me on court, no?

"I really believe that it's always in the mind that the top players get bigger advantages. And on the court it's not true. That's my feeling. I never feel that I had advantages on the court, and I really believe that he's wrong in that case.

 

"I honestly feel sorry for him. I think he played a great match for a long time. Of course, it's tough to accept to lose a match like this, especially after I was feeling destroyed and probably he felt that, [but] then I was able to manage to win the match.

"I wish him all the very best. He's young, I think we all make mistakes on our careers. I made a lot of mistakes too when I was younger, and probably he will understand later on after he thinks the proper way that probably he was not right today."

Nadal also explained why he had to be given an extended amount of time in the changeover between the first and second sets.

"I took some extra time at the end of the first set because I had to change everything there on the chair, in the changeover," he said.

"I think in that case normally at the end of the sets the umpire gives you some extra time, especially under these very humid conditions to change the clothes, because that's obvious that you can't play with the clothes in the condition that I was [in].

"I think in that moment Denis got p***** because the umpire called time and I needed like 30 seconds extra to keep changing my clothes.

"I think it's fair that Carlos gave me this extra time at that moment. I think Carlos made a small mistake in calling time. Normally at the end of the set, the umpire looks around and waits a little bit to call time until the player is a little bit ready when he's changing, no?

"Denis was wrong in that case. I understand that he just lost the set and in some way he wanted to keep playing quick, but I think he understands that normally you have some time to change your clothes."

Nadal improved his record in grand slam quarter-finals to 36-9. He is now 7-7 in Australian Open quarter-finals after surviving the Shapovalov battle, far worse than his record at the French Open (14-1), Wimbledon (7-0) and US Open (8-1).

Denis Shapovalov regrets labelling umpire Carlos Bernardes as "corrupt" but refused to relent on his view that Rafael Nadal "100 per cent" gets preferential treatment from officials.

Canadian Shapovalov fell short in a valiant comeback bid against all-time great Nadal, who eventually won through 6-3 6-4 4-6 3-6 6-3 after over four hours on Rod Laver Arena.

The 14th seed was left fuming between the first and set second, though, when he felt a time violation should have been given after Nadal made him wait for play to resume.

"Started the clock so long ago, he's still not ready to play. You've got to call him," Shapovalov said to Bernardes.

After Bernardes opted against doing so, Shapovalov said: "You guys are all corrupt."

"I think I misspoke when I said he's corrupt or whatever I said. It's definitely emotional, but I do stand by my side. I think it's unfair how much Rafa is getting away with," Shapovalov told a news conference when asked about the incident.

"I mean, I'm completely ready to play and the clock is ticking three, two, one, clicking towards zero, and I'm looking at the ump, and obviously I'm going to speak up and say something. 

"I've been ready to play for a minute and a half, and he tells me he's not going to give him a code violation because I'm not ready to play. To me, it's a big joke if somebody says that."

Shapovalov was further frustrated ahead of the deciding set where Nadal left the court for a medical check up having struggled with a stomach issue and also had a toilet break.

The 22-year-old felt the extended break quelled his growing momentum and that the elite players have different boundaries.

"And then after the fourth set, the guy goes – and for the same thing last year I wasn't allowed to take a toilet break when I asked for a medical," he added.

"He had already taken two medicals. He was getting medically evaluated, that's what the ump said after the fourth set, getting medically evaluated, and after the evaluation the guy goes and takes a toilet break.

"It's like, where is the line? Where are you going to step on the players and again, I respect everything that Rafa has done and I think he's an unbelievable player. 

"But there's got to be some boundaries, some rules set. It's just so frustrating as a player. You feel like you're not just playing against the player; you're playing against the umpires, you're playing against so much more.

"It's difficult. I mean, it was a big break after the fourth set for this reason, and the momentum just goes away. It's much more difficult to play, I think.

"Again, not trying to say anything against Rafa; he's a great player, I really respect all he's done, but I just think it's super difficult and super frustrating as an athlete to go up against all of this."

Asked if he feels Nadal gets preferential treatment, he added: "Of course. 100 per cent he does. 100 per cent. Every other match that I have played, the pace has been so quick because the refs have been on the clock after every single point.

"This one, after the first two sets it was like an hour and a half just because he's dragged out so much after every single point. He's given so much time in between sets and all this. It's just dragged out.

"Like I said, for the same reason I wasn't allowed to go to the washroom last year at the Australian Open because I had called a medical. I'm not arguing the fact that he had a medical or whatever it is. But how can you get evaluated medically and have a toilet break at the same break and just causing so much delay in the game?

"I mean, it's just not balanced."

Shapovalov and Nadal had a discussion at the net, but the former explained that it was an amicable exchange.

"It was nothing against Rafa. Rafa was serving and I would expect the umpire to be looking at Rafa and the umpire was staring me down. It didn't make sense to me," he said.

"Rafa is getting ready to serve, there's a clock right there, as an umpire you should be looking at the server. The guy is staring me down so I just looked at him like, 'Why are you looking at me?'

"It was shortly after I had said – obviously, like I said, I misspoke, but he was staring me down, so I felt like there was some feud or something. I looked at him.

"I was just explaining that to Rafa that it had nothing to do with him."

Nick Kyrgios is hoping to inspire the next generation of tennis stars after taking centre stage at the Australian Open with his run to the men's doubles semi-finals.

The 26-year-old fan favourite and partner Thanasi Kokkinakis downed sixth seeds Tim Puetz and Michael Venus 7-5 3-6 6-3 in Tuesday's quarter-final clash.

The contest was watched by a lively crowd on Kia Arena and overshadowed Rafael Nadal's five-set win over Denis Shapovalov on Rod Laver Arena at the same time.

Kyrgios and Kokkinakis, who were given a wildcard into the draw after being knocked out of the singles early on, will now face Marcel Granollers and Horacio Zeballos.

"I'm not finished – I want to win this f****** thing," Kyrgios declared in his on-court interview. "We know what we do well and it's world-class. 

"That's what we'll do again. I just want to play and give the people of Australia a show and genuinely grow the sport of tennis."

Kyrgios showed his caring side early in the match when handing a racket to a fan in the crowd after accidentally hitting the youngster with one of Kokkinakis' faulted balls.

The Australian public have embraced the pair's deep run in the competition and Kyrgios, often a controversial character, is glad to see so many younger spectators watching on.

"There is no way around it; me and Thanasi are definitely role models to the youth in Australia. We obviously attract that crowd," he said at his post-match news conference.

"I know that over the years I haven't been the best role model, but I was just learning how to deal with everything. 

"I think now at 26 I have matured, and I've definitely realised that a lot of young kids and people, even people that are low on confidence, they do look towards us.

"We are not special people. We're normal humans that you might see walking in Australia, and we are now in the semi-finals of a grand slam.

"I feel like I think we are just relatable. I think that's what's the best thing about it. They go out and get behind their mates. Most of the guys in the crowd are our mates.

"You've got Roger Federer and these guys that are just once-a-generation athletes. I can't be like that. We're not like that. I feel it has to be people that are a bit more relatable."

The Aussie pair's next opponents Granollers and Zeballos have won six tour-level titles as a team, but have never gone all the way at a grand slam.

Kokkinakis is hoping to have similar backing from the expectant home fans on Thursday.

Asked about the support he and his doubles partner have received so far, Kokkinakis said: "The rowdier the better. Sink p*** and come here.

"The next guys are experienced veterans, but we're going to keep playing how we play, have fun and enjoy the crowd."

Ash Barty was in clinical form to swat aside Jessica Pegula 6-2 6-0 in just 63 minutes and book her spot in the Australian Open semi-finals.

The world number one is still to drop a set at her home slam in Melbourne and made easy work of her opponent as Barty continued her bid to become the first female Australian singles champion since Chris O'Neil in 1978.

Barty won nine games in a row from 3-2 up in the first set to take complete command and she can now prepare for a semi-final showdown with another American in the form of Madison Keys.

A nervy-looking Pegula was rushing her shots in the early exchanges and Barty broke in the first game when a forehand cross set up a break point chance that her opponent put into the net.

Barty had chalked up 12 unforced errors by game four, but it was her aggressive tactics that had Pegula completely on the ropes and when a thumping forehand set up another break point in game seven, it was little surprise when it was converted.

By this point Barty was in complete command and Pegula had no answer to the variety of shots her opponent rained down on her.

The second set raced by in just 28 minutes, with Barty putting the finishing touch on a mightily impressive performance when Pegula put a return long on the second match point.

"Jess is an incredible person and a brilliant girl. I love to test myself against her. She's had sensational couple of years, she's definitely a top-20 player, there's plenty more to come for sure," Barty said after the match.

On reaching the semis in Melbourne for the second time after doing so in 2020, she added: "I've grown as a person, as a player, I'm a more complete tennis player.

"Credit to my team, they do so much work behind the scenes to make me the best version of myself, I love playing out here. Hopefully I've got a little bit more left."

DATA SLAM: Barty serves up a treat again

Barty defeated both Pegula and Keys en route to winning her maiden slam title at the 2019 French Open and history could be repeating itself here with the world number one playing arguably the best tennis of her career.

Behind her dominance is phenomenal success on serve. Barty is still yet to drop a set in Melbourne, and went 63 games without being broken before Amanda Anisimova did so in the previous round. Here, she lost just five points on first serve (22 of 27, 81 per cent) and gave up just a solitary break-point opportunity in the match.

Rafael Nadal survived a huge scare to reach the Australian Open semi-finals with an enthralling five-set win over Denis Shapovalov on Tuesday.

Nadal is two wins away from a record-breaking 21st grand slam title after enduring a four-hour epic to beat Shapovalov 6-3 6-4 4-6 3-6 6-3 on Rod Laver Arena.

A year after losing from two-sets-to-love up at the same stage to Stefanos Tsitsipas, there was almost a repeat for Nadal.

But, seemingly battling a stomach issue, the Spaniard remained alive in his bid to set the outright record for most grand slams won by a man, following a thrilling battle that lasted four hours, eight minutes.

The success saw Nadal – who will face either Matteo Berrettini or Gael Monfils in the last four – reach his 36th career grand slam semi-final and seventh at Melbourne Park, where he claimed the title in 2009.

Nadal landed the first blow with a break to love in the fourth game.

A superb forehand winner down the line got Nadal going before three wild forehands in a row from Shapovalov saw him fall 3-1 behind.

Shapovalov was unable to make any inroads against the Nadal serve, winning just five return points in a 39-minute opening set.

The Canadian was angry with chair umpire Carlos Bernardes' decision not to give Nadal a time violation between sets and the players unusually met at the net before the second game of the second set.

Nadal needed a tough hold during a 12-point sixth game and he capitalised in the next, an overhead securing the break after Shapovalov had sent a forehand well long at 30-30 to end a point he had been in complete control of.

Nadal closed out the set, but found trouble in the sixth game of the third as he faced break points for the first time after a double fault.

After saving both and holding serve, Nadal was broken at the key time – when serving to stay in the set – as Shapovalov delivered a backhand cross-court winner to extend the contest.

The momentum had well and truly swung and a double fault from Nadal saw Shapovalov break for 3-1 in the fourth set.

Approaching the three-hour mark, Nadal required a medical timeout, seemingly suggesting an issue with his stomach.

Shapovalov found himself in some trouble trying to level the match, but recovered from 15-40 to force a fifth set.

Nadal – who had been beaten from two-sets-to-love up just twice previously in his grand slam career – had to save a break point in the opening game of the decider, a volley winner to hold drawing huge cheers from the Rod Laver Arena crowd.

Instead, Shapovalov played a loose game, two wayward forehands, a double fault and a framed backhand giving Nadal a break and 2-0 lead.

Nadal, looking far more energetic, saved two break points in the third game before becoming more comfortable on serve on his way to the last four, Shapovalov smashing his racquet after match point.

 

DATA SLAM: Nadal overcomes major Melbourne hurdle … just

Nadal improved his record in grand slam quarter-finals to 36-9, but the last eight has often been a problem in Melbourne during his incredible career.

He is now 7-7 in Australian Open quarter-finals after surviving the Shapovalov battle, far worse than his record at the French Open (14-1), Wimbledon (7-0) and US Open (8-1).

Denis Shapovalov hit out at chair umpire Carlos Bernardes in an extraordinary outburst during his Australian Open clash against Rafael Nadal.

Shapovalov was furious with Bernardes' decision not to call a time violation against Nadal after the Spaniard left him waiting between the first and second sets on Rod Laver Arena on Tuesday.

Nadal had taken the first set 6-3, but forced the Canadian 14th seed to wait before he could serve to start the second.

"Started the clock so long ago, he's still not ready to play. You've got to call him," Shapovalov said to Bernardes.

After Bernardes opted against doing so, Shapovalov said: "You guys are all corrupt."

Nadal and Shapovalov met at the net between the first and second games of the set in a brief discussion that eased the tension.

After Nadal led 6-3 6-4, Shapovalov hit back to take the third set 6-4 on a hot day in Melbourne.

Madison Keys is enjoying being the underdog after moving into the Australian Open semi-finals on Tuesday.

The American was too good for Czech fourth seed Barbora Krejcikova 6-3 6-2 in their quarter-final, played on a warm day in Melbourne.

Keys reached her fifth career grand slam semi-final, but first since the 2018 US Open.

Riding a 10-match winning streak after claiming just 11 victories in all of 2021, Keys is staying focused as her run continues in Australia.

"I honestly feel pretty neutral, to be completely honest with you. I have gone into every match thinking I can absolutely win any match that I'm out on the court," she said.

"I will say it's been kind of nice to be the underdog for the first time in a long time.

"It's really just not even in my head about winning and losing. It's really just going out, competing, trying to do what the game plan is.

"If that's not working going to Plan B. The rest is kind of not even getting into my brain."

The heat on Rod Laver Arena seemed to get to Krejcikova, the French Open champion taking a medical timeout late in the first set.

Krejcikova said she would learn a lot from her run after struggling with the heat on Tuesday.

"Today it was the heat with some physical conditions that started to bother me during after five games. I mean, from there on, you know, I just couldn't put it together," she said.

"Just still I didn't want to end it up. I wanted to finish match. I wanted to try to do my best. Yeah, I wasn't really able to do that. Still I think it's a really good experience and I can learn a lot from it."

Keys will play either Ash Barty or Jessica Pegula in the last four.

Madison Keys moved into her first grand slam semi-final since 2018 with a straight-sets win over Barbora Krejcikova at the Australian Open.

Keys overcame Czech fourth seed Krejcikova 6-3 6-2 in hot conditions on Rod Laver Arena on Tuesday.

After a hard-fought 50-minute first set, Keys handled the heat the better of the two, closing out a deserved victory.

The win booked Keys a first major semi-final since the 2018 US Open and fifth of her career, with either Ash Barty or Jessica Pegula awaiting her.

After claiming just 11 match victories in 2021, Keys is on a 10-match winning streak, although she was challenged by Krejcikova, particularly early on.

A pair of break points went begging for Keys in the second game before she dug herself out of a 15-40 hole to hold for 2-1.

Keys held after a gruelling 18-point fifth game, one which looked set to be hugely important, after saving four break points.

Another lengthy game followed as opportunities, this time for Keys, came and went before Krejcikova sent a forehand wide to hand the American a 4-2 lead.

Krejcikova took a medical timeout at 2-5, but there was no stopping Keys taking the first set in 50 minutes.

The unforced errors continued to come from Krejcikova and a tame backhand into the net handed Keys a break in the opening game of the second set.

Looking increasingly weary, Krejcikova was broken to love in the third game, although the French Open champion did get one of those breaks back immediately.

Krejcikova continued to fight, but Keys powered away, breaking for 5-2 on her way to the last four.

 

DATA SLAM: Keys lands top-five win

Keys, the 2017 US Open runner-up, held an 8-20 record against top-five ranked opponents, and 2-6 at grand slams, heading into her meeting with Krejcikova.

The American at least improved that record and deservedly so, getting the better of Krejcikova.

Kaia Kanepi surprised even herself by holding her nerve to eliminate second seed Aryna Sabalenka in a final-set tie-break and reach Australian Open quarter-finals for the first time.

The world number 115 edged a topsy-turvy battle 5-7 6-2 7-6 (10-7) on Margaret Court Arena to set up a meeting with Iga Swiatek in the final eight.

With Monday's impressive comeback win, Kanepi has now completed a clean sweep of reaching the quarter-finals of all four majors, making her the 15th active player to do so.

But after squandering four match points in the 10th game of the deciding set, Kanepi admits she struggled to keep her nerves in check when the match went the distance.

"I thought I was going to lose it after the match points I had on my serve," said the 36-year-old, who finished with 30 winners and 30 unforced errors.

"It was really difficult to come back. I don't know how I managed to do it.

"I was really tight. My hand was shaking when I started serving. I didn't make any first serves in, and that added to the pressure.
 
"It was quite crazy. I think I would be more happy if I won after two, three match points. It was really close that I lost the match. I feel a bit exhausted right now.

"The Australian Open was the only quarter-final grand slam I was missing. Given my age, I didn't actually believe I was going to do it. I'm really happy."

After sealing a 14th career victory over a top-10 opponent, with her second win in a row against Sabalenka, Kanepi is now relishing Wednesday's battle with Swiatek.

That will pit the youngest and oldest remaining players left in the draw against each other, with 20-year-old Swiatek having earlier defeated Sorana Cirstea in three sets.

"I haven't watched her, I never played her, and I don't know how her ball feels, so we'll see when I play her," Kanepi said of her next opponent. "What I expect is to play good."

Kanepi is one of six Australian Open quarter-final debutants remaining, with top seed Ash Barty and Madison Keys the only two to have previously reached this stage.

Daniil Medvedev's temper threatened to boil over during his match against Maxime Cressy, as the world number two reflected on a "crazy" final set.

Medvedev beat Cressy 6-2 7-6 (7-4) 6-7 (4-7) 7-5 on Monday to ensure his place in the quarter-finals of the Australian Open.

The second seed is the fifth Russian man in the Open Era to reach the quarter-finals in Melbourne on multiple occasions, joining Yevgeny Kafelnikov (five), Nikolay Davydenko (four), Aleksandar Metreveli and Marat Safin (both three).

Medvedev had it far from easy against the world number 70, who reached the final of the Melbourne Summer Set earlier this month, losing to Rafael Nadal, and the match lasted three hours and 30 minutes on Margaret Court Arena.

Indeed, Medvedev was extremely tense in the fourth and what proved to be final set, as he squandered eight chances to break before finally doing so to nudge himself into a 6-5 lead. 

His temper frayed at 2-2, however, with Medvedev shouting: "It's simply unbelievable how lucky he is. I've never seen anything like this in my life."

Medvedev eventually served out the win, taking the first match point on offer, but the US Open champion knew he had been in a battle.

"He really did [serve and volley] well," Medvedev said. "First set I had control, but the second set I didn't manage to break him but won the tie-break and just wanted to continue this way.

"When I lost the third [set] and when I had eight break points in the fourth set, I was like, come on. Some of them I could have won, but he played well, but on the last one I played well.

"It was not easy. If I didn't win the fourth [set] I'd have probably been in a difficult mental shape because I had so many breakpoints. Hell of a match. The fourth set was crazy."

Overall it was a deserved win for Medvedev, who made only 11 unforced errors in contrast to Cressy's 49, and even if he only took three out of 12 break points, the 25-year-old offered up just one to his opponent, which the French-born American failed to capitalise on.

Another annoyance for Medvedev was that he was again scheduled to play on Margaret Court Arena, rather than the crown jewel at Melbourne Park, Rod Laver Arena.

"I really don't know what I should do to play on centre court here," he told reporters.

Next up for Medvedev is a quarter-final tie against ninth seed Felix Auger-Aliassime.

Medvedev has defeated the 21-year-old Canadian in all three of their previous meetings on the ATP Tour, including in his successful run to US Open glory last year, and in the ATP Cup earlier this month.

An emotional Alize Cornet said "it is never too late to try again" after reaching her maiden grand slam quarter-final with victory over Simona Halep at the Australian Open.

Cornet, who celebrated her 32nd birthday on Saturday, battled to a 6-4 3-6 6-4 victory in stifling conditions on Rod Laver Arena to set up a last-eight showdown with Danielle Collins, who beat Elise Mertens in three sets.

The Frenchwoman has now defeated two in-form former number ones in Halep and Garbine Muguruza, having also recovered from a set and 1-4 down to overcome Tamara Zidansek.

She is through to her first quarter-final in what is her 63rd grand slam appearance and is the first Frenchwoman to reach this stage at Melbourne Park since Marion Bartoli in 2009.

Cornet is playing in her 60th straight major, and should she compete in the main draws at Roland Garros, Wimbledon and Flushing Meadows, will set a new record for consecutive appearances in grand slams.

"It feels amazing," Cornet said in her on-court interview with Jelena Dokic. "It was a battle with Simona today. In this heat after 30 minutes we were both dying on the court.

"We kept going for two and a half hours with all our heart. Congrats to Simona because I know she struggled a lot and I admire this player so much. 

"She's such a fighter and an example to me. To beat her today to go to my first quarter-final is a dream come true. I don't know what to say. It's just magic. It's never too late to try again.

"This is why I keep playing tennis, for this moment where I can share all these emotions on the court with you."

Cornet had reached the last 16 at majors on five occasions prior to her victory over Halep in a run dating back 13 years when narrowly missing out on the Australian Open quarter-finals.

She was pegged back from a set and break up against Halep, losing 16 straight points at one point, and was clearly struggling with the heat as the match dragged into a decider.

But Cornet, who recently suggested this might be her final season playing professional tennis, showed incredible resolve to break Halep in the seventh game and hold her own serve to break her quarter-final hoodoo.

Halep congratulated Cornet, posting to her official Instagram account: "You have been stronger today! All the respect for you, Alize. Enjoy. I'll keep working to get better for another three-hour match when we meet again."

In her post-match media duties, Halep said: "I have only nice words about her, because I like her on court, how she's fighting.

"She deserves what is happening to her now. She works hard all the time, and I wish her good luck. I really want her to make this dream coming true."

There was to be another emotional moment for Cornet at the end of her victory speech as she praised 2009 Australian Open quarter-finalist Dokic for her work off the court since retiring eight years ago.

"I want to thank my box, but also I want to tell you something... how you moved on in your life, I think we can all congratulate you. You were an amazing player and now an amazing commentator," Cornet said as the pair embraced on court.

Dokic, who last week called out social media trolls for body-shaming her, responded: "You just made me cry. I can’t believe I'm crying. Thank you. Alize Cornet."

Matteo Berrettini made Italian tennis history on Sunday as he blasted his way past Pablo Carreno Busta and into the Australian Open quarter-finals.

The seventh seed won 7-5 7-6 (7-4) 6-4 in a gruelling contest to set up a last-eight clash with Gael Monfils, who earlier beat Miomir Kecmanovic.

Berrettini is the first men's player from his country to reach the quarter-final stage of all four grand slams in the singles draw, and only the 10th active player to achieve the feat.

The 25-year-old only reached this stage of a major for the first time in 2019 and has since gone as far as the final in Wimbledon last year, where he lost to Novak Djokovic.

Having withdrawn from his round-of-16 match with Stefanos Tsitsipas in Melbourne in 2021 due to an abdominal injury, Berrettini was delighted to have progressed.

"It was really tough last year. I really wanted to play, but I couldn't with the tear in the ab," he said.

"But I believe there is a reason for everything that happens and I've been wishing to come back as soon as possible and the way I won today shows how much I care about this tournament."

Berrettini had luck on his side in the first set as two netcords on Carreno Busta's serve allowed him to break for a 6-5 lead.

Once ahead in the match, his serve and baseline power became too much for the Spaniard: Berrettini rained down 28 aces, winning 87 per cent of points behind his first serve, and hit 57 winners.

"I was really precise with my serving and he wasn't reading my serve, which is why I hit a lot of aces," he said.

Next up is a meeting with Monfils, who has now reached 10 slam quarter-finals in his career and a first in Australia in six years.

These two met at the same stage of the 2019 US Open, Berrettini prevailing in five sets after losing the first two. The winner could face Rafael Nadal in the semi-finals.

"It's been a long journey for me and I'm quite happy, but it's not finished," said Monfils. "I will try to play this quarter-final not like the last time. I will try to be better.

"It's an achievement but we're not quite finished yet."

World number one Ash Barty promised to carry on playing her own game after booking her spot in the last eight of the Australian Open.

Barty, the top seed, defeated Amanda Anisimova 6-4 6-3 on Sunday to progress to the quarter-finals in Melbourne for a fourth successive time.

Anisimova defeated last year's champion Naomi Osaka in the last round, but she proved no match for Barty, who sealed the win in 74 minutes.

Barty did see her run of holding serve ended, however, after 63 games without being broken, though it was a minor blip in another convincing win. 

Indeed, the 25-year-old has now won all four of her Australian Open ties without dropping a set.

Asked what was key to her dominant form, Barty said: "I think the most important thing is I just try to be me, continue to be me, that's all I can do.

"That's what I’m good at, that's who I and who I want to be."

Her comments were well received by the crowd at Rod Laver Arena, and Barty is delighted to be playing in front of spectators once again.

"The last two years have been extraordinarily tough for a lot of people around the world," she said.

"To have the crowd here, it brings a lot more to the tennis. It makes it a lot more enjoyable for me to play at home."

Barty struck seven aces and registered a first-serve percentage of 78, while also hitting 23 winners and making exactly half the amount of unforced errors as Anisimova (17 to 34).

"Amanda is an incredible athlete and incredible competitor. It's nice to see her back playing her best tennis," Barty continued.

"I enjoyed sharing the court with her and testing myself against her. It was nice to be able to hold firm tonight."

Asked in a post-match news conference about dropping serve for the first time in eight matches, Barty replied: "It didn't bother me too much.

"Honestly, I'm not counting how many games I hold in a row or not. The fact I was able to reset, break straight back, was really important, just to be able to reset myself, go again and continue to do the right things."

Next up for Barty, a two-time major winner who is yet to taste victory in her home grand slam, is another American in the form of Jessica Pegula, who upset fifth seed Maria Sakkari 7-6 (7-0) 6-3.

"It's going to be a challenge for me to try and push her off that baseline and make her uncomfortable and feel like she has to create," Barty told reporters.

"But I know that she's also going to be doing the exact same thing to me and trying to make me uncomfortable.

"That's the chess game that we play. You go out there and have fun with it, see who can execute better on the day, and that's about all there is to it."

Denis Shapovalov said it is a privilege to be facing Rafael Nadal in the Australian Open quarter-finals after his win over Alexander Zverev, who conceded "everything" went wrong.

Zverev had been looking sharp in Melbourne over the last week, with the world number three not dropping a single set en route to the last 16.

Yet the Olympic gold medallist was on the end of a straight-sets loss on Sunday as he went down 6-3 7-6 (7-5) 6-3 to Shapovalov.

Zverev made 32 unforced errors, five fewer than Shapovalov, and managed to convert only two of five break points, with the German winning 46/67 first-serve points.

Asked what went wrong, Zverev bluntly told reporters: "Everything.

"It's no one else's fault. It's not the coach's fault, it's not my team's fault, it's no one else's fault. It's purely me.

"As world number three, I have to take responsibility for the things I do and don't do.

"I give credit to Denis. It's incredible that he's in the quarters, I think he deserves it. He's done a lot of work, improved his game.

"But I've got to look at myself. Today was just, in my opinion, awful from my side."

Shapovalov had lost to Zverev in the ATP Cup earlier this month, but after Sunday's win the duo's head-to-head record stands at 4-3 in the latter's favour.

The 22-year-old Canadian will now face Nadal, with the 20-time grand slam winner having progressed to his 14th Australian Open final by defeating Adrian Mannarino.

Nadal holds a 3-1 head-to-head record against Shapovalov, though this will be the first time the pair have met in a major.

"It's always an honour to go up against a guy like Rafa," said Shapovalov after reaching his first Australian Open quarter-final.

"It's always going to be a battle against him. It's going to be a tough one and I'm definitely going to enjoy it."

Reflecting on just his second career win over a player in the top five, Shapovalov said: "I think off the ground I was playing really well, really feeling my shots off both wings.

"I played pretty smart, it felt like things were going my way early on. I lost a little bit of momentum midway in the second set but fought well to come back and just kind of rolled with it after."

It was also the first time in the tournament that Shapovalov had not had to go to at least four sets.

"It's probably the one I least expected to finish in three. I'm very happy with my performance, definitely happy with where my game is at," he added.

Ash Barty's dominant form at the Australian Open continued as the world number one saw off Amanda Anisimova to reach the quarter-finals.

Anisimova shocked 2021 champion Naomi Osaka in the last round but the in-form Barty proved a step too far on Sunday.

Barty had not dropped a set in any of her previous matches and the Australian continued that trend with a 6-4 6-3 triumph that took just 74 minutes.

The 25-year-old missed five chances to break before she finally nosed herself ahead in a tightly contested first set when Anisimova went long.

Anisimova made the same mistake in the next game, failing to grasp the opportunity for an immediate response, and Barty struck a forehand winner to claim the set.

World number 60 Anisimova responded by racing into a 40-0 lead at the start of the second set, only for some sloppy shots to allow Barty to haul herself level.

The American held her nerve though and looked to be right back into it when she broke Barty in the next game.

Yet two-time major winner Barty hit straight back, with a missed backhand from Anisimova gifting her a reprieve, and she did not look back, holding serve before breaking again to go 4-3 ahead.

Anisimova saved two match points in her win over Osaka, yet another overhit backhand sent Barty through to a tie against Jessica Pegula at the first time of asking.

DATA SLAM: BARTY'S HOLD STREAK OVER

There was one negative for Barty, who failed to hold serve for the first time in 63 games when she was broken in the second set. However, the Queenslander responded to that streak ending with a display of her title-winning quality to reach a fourth successive Australian Open quarter-final.
