Jannik Sinner announced himself as a grand slam force in stunning fashion by becoming the first player in six years to defeat Novak Djokovic at the Australian Open.

The 22-year-old Italian was seen as the most likely rival to stop Djokovic claiming an 11th title in Melbourne ahead of the tournament after beating him twice in two weeks at the end of last season at the ATP Finals and Davis Cup.

But surely no one would have predicted the manner of the first two sets of this semi-final, with an error-strewn Djokovic winning just three games.

He saved a match point in the third-set tie-break to give himself hope but there was no dramatic comeback, with Sinner regrouping impressively and going on to clinch a 6-1 6-2 6-7 (6) 6-3 victory after three hours and 22 minutes.

The fourth seed moves through to a first grand slam final while Djokovic, who had not lost here since a fourth-round defeat by Hyeon Chung amid elbow problems in 2018, must lick his wounds, with a record 25th slam title proving beyond him for now.

The result was, of course, a shock given Djokovic’s incredible record here – this is the first time he has ever lost having made it beyond the quarter-finals – but it was the Serbian’s display that was the most surprising.

He committed 54 unforced errors and did not even make Sinner use his haymaker groundstrokes that often, the Italian instead able to maintain a very high but comfortable level and not facing a single break point.

Djokovic struggled with illness at the start of the fortnight and had a tougher passage through to the last four than usual, losing three sets along the way.

Sinner, the first Italian to make an Australian Open singles final, had not dropped a set all tournament, and he started as he meant to go on, breaking the Djokovic serve to lead 2-0 with a searing forehand followed by a drive volley winner.

By contrast, nothing was working for Djokovic, with routine shots landing in the net or out of court, while he was also struggling on serve.

Sinner broke again to lead 5-1 and wrapped up the first set with just over half an hour gone.

Djokovic is a master at pacing himself in best-of-five-sets tennis and he would certainly not have panicked having lost only two of the last 17 slam matches in which he dropped the first set.

But the pattern of the match continued in the same vein, with more Djokovic errors helping Sinner break for 2-1 in the second set.

Djokovic whipped up crowd support after saving a break point at 2-4 in fine style but Sinner broke anyway two points later and served out the set.

Two years ago at Wimbledon, Sinner led Djokovic by two sets to love only to lose in five, so he knew very well that the match was far from over.

Djokovic, who had barely showed any emotion, clenched his fist after saving a break point in the opening game of the third set, and he at least managed to serve better.

At 5-5 and deuce on the Serbian’s serve, a medical emergency in the crowd forced a delay for several minutes, but Djokovic held his nerve on the resumption.

The world number one knew it was now or never in the tie-break, and he opened up a 4-2 lead, but Sinner surged back, creating a match point at 6-5 but netting a forehand, and a backhand over the baseline two points later gave Djokovic a lifeline.

He was still hanging on, though, saving three break points in the second game of the fourth set only to then be broken from 40-0 two games later.

Djokovic forced Sinner to serve it out but the Italian did not waver, clinching the biggest win of his life with a forehand winner.

Defending champion Aryna Sabalenka will take on first-time grand slam finalist Zheng Qinwen for the Australian Open crown on Saturday.

Sabalenka reversed the result of the US Open final, beating Coco Gauff 7-6 (2) 6-4, while 12th seed Zheng ended the run of qualifier Dayana Yastremska with a 6-4 6-4 victory.

Britain’s Alfie Hewett is one win away from defending his wheelchair title and will again face Japanese teenager Tokito Oda for the trophy.

The men take centre stage on Friday, with Novak Djokovic putting his 33-match unbeaten run at Melbourne Park on the line in a semi-final clash against fourth seed Jannik Sinner.

In the night session, familiar foes Daniil Medvedev and Alexander Zverev will do battle for a place in the final.

Britain’s Neal Skupski goes for a fourth grand slam title alongside American Desirae Krawczyk in the mixed doubles final, with the pair taking on Hsieh Su-wei and Jan Zielinski.

Aryna Sabalenka has her sights on a second straight Australian Open title after a successful revenge mission against Coco Gauff.

Gauff denied Sabalenka a second grand slam title of the year with victory in the US Open final last summer but her winning run at the majors came to an end with a 7-6 (2) 6-4 defeat under the roof on Rod Laver Arena.

Sabalenka will now be a big favourite to successfully defend her title at Melbourne Park on Saturday when she takes on first-time slam finalist Zheng Qinwen, who defeated Dayana Yastremska 6-4 6-4.

Sabalenka has been in tremendous form this fortnight, not losing more than three games in any set prior to this semi-final meeting.

Gauff’s stellar powers of defence, which turned the tables in New York after she had lost the first set, ensured she got significantly closer than any of Sabalenka’s previous opponents, but it was still not enough.

“It was (an) incredible match,” said the second seed. “She’s a great player, always tough battles against her. I think the key was that I was able to stay focused no matter what. I just kept trying my best, kept fighting for it.

“Of course I’m super happy to be in another final of the grand slam. Hopefully I can do a little bit better than the last time.”

Gauff made a poor start, with five double faults in her first three service games helping Sabalenka open up a 5-2 lead.

But Gauff’s ability to get one more ball back in play better than anyone else in the women’s game had put Sabalenka into meltdown mode in New York and she threatened the same here.

Sabalenka failed to serve out the set at 5-3 and Gauff saved a set point in the next game before making it four games in a row, the crowd gasping as the Belarusian pushed a forehand wide with the whole court at her mercy.

Gauff was two points away from taking the set but Sabalenka refused to let history repeat itself and forced a tie-break, where she put on a display of awesome power that even the athletic American could find no answer to.

The second was nip and tuck but Sabalenka got the crucial break at 4-4 and served out the victory to become the first woman since Serena Williams in 2016 and 2017 to reach successive finals here.

Gauff looked emotional leaving the court but she rated her performance as better than in the US Open final, saying: “I felt like it wasn’t a great match for me. Yes, I won. I think I played better tonight.

“I wish I could have made more first serves. I think that was the difference. She had a higher first-serve percentage, and it’s tough to also go for the second when you double-faulted a couple times.

“I put myself in the position to serve out the set. At the end of the day, it came down to a couple of points. Same in the second.”

The 19-year-old immediately found perspective at the end of her final slam as a teenager, saying: “I watched these matches growing up, watching Serena (Williams) and (Maria) Sharapova lose these matches.

“When you’re in it, it feels like the end of the world. But then, when you look at history, they didn’t let one match define their career.

“I’m going to dwell on it tonight but, as (coach) Brad (Gilbert) told me as soon as the match was over, the sun is going to rise tomorrow and you have a new chance to live a good day. Tomorrow I’m going to try to go to the movies or something, be proud of myself.”

Twelfth seed Zheng has kept her head while the more fancied players in the top half of the draw have fallen around her.

Yastremska was trying to emulate Emma Raducanu by reaching a grand slam final as a qualifier but she came out second best in a big-hitting encounter.

Zheng, who has not yet faced a top-50 opponent, is the first Chinese player to make it to a slam decider since Li Na won the title here a decade ago.

The 21-year-old said: “It feels unbelievable. I’m super excited to have a such a great performance today and arrive in the final.”

Aryna Sabalenka took her revenge against Coco Gauff to make it back-to-back Australian Open finals.

Gauff denied Sabalenka a second grand slam title of the year with victory in the US Open final last summer but her winning run at the majors came to an end with a 7-6 (2) 6-4 defeat under the roof on Rod Laver Arena.

Sabalenka will now be a big favourite to win a second-straight title at Melbourne Park on Saturday.

The second seed has been in tremendous form this fortnight, not losing more than three games in any set prior to this semi-final meeting.

Gauff’s stellar powers of defence, which turned the tables in New York after she had lost the first set, ensured she got significantly closer than any of Sabalenka’s previous opponents, but it was still not enough.

Sabalenka came out firing, winning the first seven points and immediately breaking the Gauff serve.

Nerves were on show from both and Gauff hit back to level, but five double faults from the American in her opening three service games proved very costly and Sabalenka opened up a 5-2 lead.

Gauff’s ability to get one more ball back in play than anyone else in the women’s game had put Sabalenka into meltdown mode in New York and she threatened the same here.

Sabalenka failed to serve out the set at 5-3 and Gauff saved a set point in the next game before making it four games in a row, the crowd gasping as the Belarusian pushed a forehand wide with the whole court at her mercy.

Gauff was two points away from taking the set but Sabalenka refused to let history repeat itself, forcing a tie-break, where she put on a display of awesome power that even the athletic American could find no answer to.

Gauff kept her nose in front on serve in the second set and a real test of Sabalenka’s nerve arrived when she trailed 0-30 in the eighth game.

But the 25-year-old responded with four exceptional points, broke Gauff in the next game and served out the victory to become the first woman since Serena Williams in 2016 and 2017 to reach successive finals here.

Novak Djokovic puts his 33-match unbeaten Australian Open run to the test against Jannik Sinner on Rod Laver Arena on Friday.

The world number one has not been beaten at Melbourne Park since a fourth-round loss to Chung Hyeon back in 2018, with only two opponents in the intervening six years managing to push him to five sets.

Djokovic appears to have recovered from the illness that was troubling him at the start of the fortnight, but was tested in a four-set quarter-final win over Taylor Fritz and, if anyone is going to end his streak, Sinner appears a prime candidate.

The 22-year-old beat Djokovic twice in successive weeks at the end of last season at the ATP Finals and Davis Cup, where he led Italy to the title, and is the only player in the men’s draw yet to drop a set.

“This is what I practise for, to play against the best players in the world,” said Sinner. “Obviously he has an incredible record here, so for me it’s a pleasure to play against him, especially in the final stages of the tournament where things are a little bit more interesting.

“I’m looking forward to it. It’s going to be tough. This, I know. I will control the controllable, which is giving 100 per cent, having the right attitude, fighting for every ball. And then we see the outcome. More than this, I cannot do. It doesn’t really matter who my opponent is.”

Sinner reached his first slam semi-final at Wimbledon last summer but lost in straight sets to Djokovic, who is tantalisingly close to a record-breaking 25th major title.

This has not been one of his more straightforward paths through the draw in Melbourne, but his desire to continue racking up the biggest titles remains unquestionable.

“I’m aware of the streak that I’m on and the amount of matches that I have won in my career on the Rod Laver Arena,” said Djokovic.

“I don’t want to let that go. The longer the streak goes, the more that kind of confidence, also expectations, build, but also the willingness to really walk the extra mile.”

The second semi-final pits two very familiar opponents against each other in the shape of third seed Daniil Medvedev and sixth seed Alexander Zverev.

Medvedev is bidding to reach his third final at Melbourne Park in the last four years while Zverev crashed the top-four party by defeating Carlos Alcaraz on Wednesday for his best victory at a slam.

Medvedev and Zverev, who are certainly not the best of friends, have played each other 18 times previously but strangely never at a slam.

Russian Medvedev leads the head-to-head 11-7 having won five of the six matches they played last season, but Zverev took time to get back to his best after a serious ankle injury.

“A lot of matches were extremely close,” said the German, who lost his only grand slam final at the US Open in 2020.

“A lot of the times it came down to him being extremely confident last year, him playing some of the best tennis of his life, and me coming back from injury and not having the confidence in deciding moments and not being able to finish matches.

“He’s obviously extremely difficult to play. No question about it. He’s one of the best players in the world right now. But I’m happy in the position I am, and I’m going to do everything I can to win that match on Friday.”

Carlos Alcaraz insisted he was happy with his Australian Open efforts despite falling to a quarter-final loss against Alexander Zverev.

The Wimbledon champion had been in excellent form in Melbourne and threatened a comeback after a slow start but it was Zverev who moved through to the last four thanks to a 6-1 6-3 6-7 (2) 6-4 victory clinched at 1.19am.

In his seventh grand slam semi-final, Zverev will take on third seed Daniil Medvedev, who earlier battled past Hubert Hurkacz in five sets.

Alcaraz was heavily fancied to make it an all top-four semi-final line-up but he looked very tight at the start and Zverev took full advantage, barely missing a first serve and striking his groundstrokes with power and precision.

The German has faced a lot of off-court scrutiny regarding his forthcoming domestic abuse trial – he denies the allegations – but his ability as a tennis player is unquestionable.

Alcaraz briefly rallied in the second set but he was staring at defeat inside two hours when Zverev served for victory at 5-3 in the third.

The Spaniard was not done yet, finally breaking the Zverev serve and then playing a sublime tie-break, but ultimately there were too many errors from his racket.

This was Alcaraz’s best run in Melbourne, and he said: “It has been a good tournament for me, making quarter-finals, playing good tennis.

“I’m sad with my level today, because I have been playing good tennis, the round before this one with a lot of confidence. Serving pretty well.

“But in general I leave the tournament happy. Forgetting about today’s level. Obviously quarter-final of a grand slam is good. It’s not what I’m looking for, but it’s not bad.

“It’s a shame that I started the match like the way that I did and ending the way that I did. But it’s tennis.”

Alcaraz played down the impact of being without his coach Juan Carlos Ferrero, who is back in Spain recovering from knee surgery.

“It didn’t affect (me) at all,” said the 20-year-old. “As I said, I was playing great tennis without him. I had Samuel (Lopez), that is a pretty good coach as well. I trust him 100 per cent.”

Zverev, who lost his only grand slam final to Dominic Thiem at the US Open in 2020, received treatment for blisters on his foot at the end of the third set but rallied well, helped by a phenomenal serving display.

“When you’re up 6-1 6-3 5-2, you start thinking,” said the sixth seed, for whom this was a first win over a top-five opponent at a grand slam.

“It’s not always helpful but I’m happy I got there in the end. I fought back quite well in the fourth set.”

Earlier, Medvedev struggled in the heat of the day against ninth seed Hurkacz, who was looking to make the last four at a grand slam for only the second time.

The Pole twice fought back from a set down but Medvedev came out on top 7-6 (4) 2-6 6-3 5-7 6-4 after three hours and 59 minutes.

The Russian finished it off with a drop shot before blowing kisses towards his box.

Medvedev will now try to reach the final for the third time in four years, and he said: “I’m so destroyed right now. I was feeling very tired physically at the end of the second set already.

“In the fourth set, he played good, I wasn’t beating myself up. I had no more concentration, I thought, ‘I just have to try my best to do whatever I can. If I lose, I lose and I go home. It’s OK’.

“I’m happy that like this I managed to win and I really liked the match point.”

Carlos Alcaraz became the biggest casualty of the men’s draw so far at the Australian Open.

The second seed was beaten in four sets by Alexander Zverev, who will take on Daniil Medvedev in the semi-finals following his five-set victory over Hubert Hurkacz.

Qualifier Dayana Yastremska made it through to the last four in the women’s draw, where she will play another first-timer in 12th seed Zheng Qinwen.

Who’s up next?

It is women’s semi-finals day on Thursday, with both matches taking place in the night session.

First up is a rematch of the US Open final, with defending champion Aryna Sabalenka hoping to turn the tables on Coco Gauff, before Yastremska plays Zheng.

British wheelchair stars Alfie Hewett and Gordon Reid are in singles and doubles semi-final action, while Mingge Xu plays her girls’ singles quarter-final against Iva Ivanova.

Carlos Alcaraz’s hopes of a first Australian Open title ended in a quarter-final defeat by sixth seed Alexander Zverev.

The Wimbledon champion had been in excellent form in Melbourne and threatened a comeback after a slow start but it was Zverev moving through to the last four thanks to a 6-1 6-3 6-7 (2) 6-4 victory clinched at 1.19am.

In his seventh grand slam semi-final, Zverev will take on third seed Daniil Medvedev, who earlier battled past Hubert Hurkacz in five sets.

Alcaraz was heavily fancied to make it an all top-four semi-final line-up but he looked very tight at the start and Zverev took full advantage, barely missing a first serve and striking his groundstrokes with power and precision.

The German had faced a lot of off-court scrutiny regarding his forthcoming domestic abuse trial – he denies the allegations – but his ability as a tennis player was unquestionable.

Alcaraz improved at the start of the second set, finding some of the dynamic, all-court play that has made him such a fan favourite, but he could not take either of two break points in the sixth game.

He then found himself under more pressure in the following game and, after being given a time violation, he netted a forehand to drop serve again.

Alcaraz, who had comfortably beaten Zverev at the same stage of the US Open last summer, looked furious with himself but he could not conjure up any response as errors continued to flow from his racket.

The end seemed nigh when Zverev, who lost his only grand slam final to Dominic Thiem at the US Open in 2020, broke serve again to lead 3-1 in the third set.

But Alcaraz roused himself just in time to break the Zverev serve for the first time at 5-3 and then reeled off a string of seven absurd points to win the tie-break and take it to a fourth set.

The German received treatment for blisters on his foot and Alcaraz seemed to have the momentum but more errors helped Zverev break to lead 5-4 and this time he managed to serve it out, securing his first victory over a top-five opponent at a slam.

“When you’re up 6-1 6-3 5-2, you start thinking,” said Zverev. “It’s not always helpful but I’m happy I got there in the end. I fought back quite well in the fourth set.”

Earlier, Medvedev struggled in the heat of the day against ninth seed Hurkacz, who was looking to make the last four at a grand slam for only the second time.

The Pole twice fought back from a set down but Medvedev came out on top 7-6 (4) 2-6 6-3 5-7 6-4 after three hours and 59 minutes.

The Russian finished it off with a drop shot before blowing kisses towards his box.

Medvedev will now try to reach the final for the third time in four years, and he said: “I’m so destroyed right now. I was feeling very tired physically at the end of the second set already.

“In the fourth set, he played good, I wasn’t beating myself up. I had no more concentration, I thought, ‘I just have to try my best to do whatever I can. If I lose, I lose and I go home. It’s OK’. I’m happy that like this I managed to win and I really liked the match point.”

It was a back-and-forth contest throughout between the two big servers, who both move tremendously well for such tall men.

Medvedev edged the first set on a tie-break and looked to be in full control when, having dropped the second, he took the third and moved a break ahead in the fourth.

But Hurkacz, who had won his last two matches against the Russian and their only previous grand slam meeting at Wimbledon in 2021, did not allow his head to drop and levelled at 4-4.

It was now Medvedev under real pressure on serve, and Hurkacz clinched his opportunity to force a decider when his opponent sent a forehand long.

Medvedev had survived a five-setter in the second round, coming from two sets down to defeat Emil Ruusuvuori at nearly 4am.

And the third seed was not to be denied, a break in the seventh game proving the difference.

A drained Daniil Medvedev scrapped his way into a third Australian Open semi-final with a five-set victory over Hubert Hurkacz.

Ninth seed Hurkacz, who was looking to make the last four at a grand slam for only the second time, twice fought back from a set down but Medvedev came out on top 7-6 (4) 2-6 6-3 5-7 6-4 after three hours and 59 minutes.

The Russian finished it off with a drop shot before blowing kisses towards his box.

Medvedev will now try to reach the final for the third time in four years, and he said: “I’m so destroyed right now. I was feeling very tired physically at the end of the second set already.

“In the fourth set, he played good, I wasn’t beating myself up. I had no more concentration, I thought, ‘I just have to try my best to do whatever I can. If I lose, I lose and I go home. It’s OK’. I’m happy that like this I managed to win and I really liked the match point.”

Medvedev had survived a five-setter in the second round, coming from two sets down to defeat Emil Ruusuvuori at nearly 4am.

And the third seed was not to be denied, a break in the seventh game proving the difference.

Nick Kyrgios says the prospect of life after tennis now “excites” him as he takes to the commentator’s box for the Australian Open.

The Australian former world number 11 has taken time off from the professional circuit due to injury, filling in his time by working at the grand slam for Eurosport.

He wrote on Wednesday in Australian newspaper The Age that he is now seriously considering retirement.

“I’m at a crossroads in my career and have reached a point where life after tennis is a prospect that excites me,” he wrote.

His words come hours after he conducted his first on-court interview of the Australian Open on Tuesday night, speaking to 24-time grand slam winner Novak Djokovic.

But, despite enjoying his time in the commentator’s box, the 28-year-old says he still feels the urge to play.

“Over the past week being at Melbourne Park for the Australian Open, I’ve been happy,” he said.

“Of course, there’s a part of me watching on that would love nothing more than to be out there.

“I know I can be one of the best in the world and win major tournaments – if my body lets me.

“The fire still burns, but it’s not my everything.”

Kyrgios attempted a comeback in June. However, his return only lasted one match thanks to continuing knee and wrist injuries.

Kyrgios said a return to the professional circuit has not been totally ruled out, but he stressed he will not put his name forward to represent Australia at the Paris 2024 Olympics.

Dayana Yastremska is two wins away from emulating Emma Raducanu after beating Linda Noskova to reach the Australian Open semi-finals.

Raducanu is the only qualifier ever to win a grand slam title but Yastremska increased her tally of wins in Melbourne to eight with a 6-3 6-4 victory on Rod Laver Arena.

The stories are not exactly comparable, given Yastremska was ranked 21 in the world as a 19-year-old before serving a six-month provisional suspension for a failed doping test, for which she was later deemed to bear no fault.

But it is nevertheless a very impressive run from the Ukrainian, now 23, who is set to soar back into the top 30 from her current ranking of 93.

She is the second qualifier in the open era to reach the last four here in the women’s singles after Australian Christine Dorey in 1978.

Yastremska said: “I think it’s nice to make history because at that time I still wasn’t born. I’m super happy, and tired. I arrived here on January 3. On the days when I have a match, they do go very fast. When I have a day off, it feels like I’ve been here for six months already.”

This was a contest of first-strike tennis, with both women looking to seize the initiative in rallies as early as possible.

But it was the extra power of Yastremska that made the difference, with the Ukrainian hitting 19 winners compared to only six for 19-year-old Noskova.

“I don’t really feel like I’m playing really good,” said Yastremska, who has beaten Wimbledon champion Marketa Vondrousova and two-time winner Victoria Azarenka during her run.

“I just try to play like I can and take the maximum from myself. Everything I have left is just fighting.”

Novak Djokovic suffered in the heat at the Australian Open but made it past Taylor Fritz and into the semi-finals.

There he will face Jannik Sinner, who finished his straight-sets victory over Andrey Rublev at 1.22am after long matches in the day session.

There will be a rematch of the US Open final in the women’s semi-finals, where defending champion Aryna Sabalenka will face Coco Gauff.

Gauff was not too impressed with mum Candi’s moment in the spotlight, saying: “I saw the video of her celebrating. I was, like, ‘it wasn’t that hard of a ball to catch. You know, celebrate your little wins’.

Who’s up next?

The quarter-finals conclude on Wednesday, when Carlos Alcaraz’s battle with Alexander Zverev takes centre stage in the night session.

The winner will face either third seed Daniil Medvedev or ninth seed Hubert Hurkacz, while China’s Zheng Qinwen is the only seed left in the top half of the women’s draw and plays Anna Kalinskaya.

Czech teenager Linda Noskova, who beat Iga Swiatek in the third round, faces qualifier Dayana Yastremska in the opening match of the day.

Australian Open organisers faced criticism over scheduling after a long quarter-final between Novak Djokovic and Taylor Fritz delayed the night session by more than two hours.

Djokovic battled past his American opponent 7-6 (3) 4-6 6-2 6-3 after three hours and 45 minutes, with the match starting later than expected because of Coco Gauff’s lengthy clash with Marta Kostyuk in the opening match of the day on Rod Laver Arena.

Extending the tournament to 15 days this year and scheduling only two matches in each day session was meant to avoid the sort of early-morning finishes that have become increasingly common.

But there have only been two days out of 10 so far where play has finished by midnight, and Daniil Medvedev and Emil Ruusuvuori played until 3.39am in their second-round clash.

Tuesday’s delay meant women’s defending champion Aryna Sabalenka did not start her match, which had been due to begin at 7pm, until 9.10pm, and Jannik Sinner and Andrey Rublev were not hitting their first balls until after 10.40pm.

Discussions took place about potentially moving one of the night session matches to a different court, but that ultimately did not happen.

Fritz said: “It just screws up your whole clock. I pray for those guys. I get it, matches go long some days. Like, today in particular, my match was long, the match before us was really long.

“But there’s got to be something they can do where people aren’t playing until 2, 3am, because I don’t think people really fully understand how much time we actually have to spend doing stuff after we finish playing. If you finish at 2am, there is no chance I’m going to sleep until 5, 6am.”

Wimbledon is unique in having an 11pm curfew, but play at the other grand slams has no cut-off point, and, with the average length of matches increasing markedly in recent years, what was rare in now commonplace.

Djokovic said: “We’ve seen in the past some late finishes. And I know for the crowds and for the tournament in a way it’s kind of exciting to see a 4am finish, a 3am finish. I was part of some of those. But it’s definitely not fun for us.

“The good thing about the quarter-finalist on the men’s section is we have two days. So I think that’s plenty of time to get a good sleep and recover.”

Djokovic will also need time to recover after battling past Fritz and into the semi-finals in Melbourne for the 11th time.

The world number one has never lost here once he has made it beyond the last eight, and there is no doubt how much he wants a 25th grand slam title.

Djokovic had beaten American Fritz in all eight of their previous meetings but this was certainly not straightforward. The first game alone lasted 16 minutes and the first set 84 minutes as they toiled in the heat.

Fritz, looking to reach a slam semi-final for the first time at the third attempt, remarkably saved all 15 break points he faced in the opening two sets, and he impressively levelled the contest.

It was just the third set he had won against the Serbian, with the other two both coming in a third-round clash here in 2021, when Djokovic suffered an abdominal injury but still managed to win in five.

But Djokovic began to turn the screw in the third set as Fritz started to feel his left foot, and successive breaks in the fourth set him on the way to a record-extending 48th slam semi-final.

Speaking to Nick Kyrgios on court, Djokovic said: “I suffered a lot in the first couple of sets. Also due to his high quality tennis. He was really kind of suffocating me from the back of the court.

“It was really difficult to find the right timing, it was really hot while the sun was still out. We all know Taylor has got one of the best serves in the world. I knew the kind of a threat he poses when he serves on such a high quality.

“Conversion of the break points was really poor but I managed to break him when it mattered. I think I upped my game midway through the third set all the way through to the end.”

Fritz was left with mixed feelings, saying: “I played a really high level for the first two sets, and they were a physical, tough two sets. It was like two and a half hours by the time we finished the two sets. I need to get to the point where I can do that for five hours.”

Australian Open organisers faced criticism over scheduling after a long quarter-final between Novak Djokovic and Taylor Fritz delayed the night session by more than two hours.

Djokovic battled past his American opponent 7-6 (3) 4-6 6-2 6-3 after three hours and 45 minutes, with the match starting later than expected because of Coco Gauff’s lengthy clash with Marta Kostyuk in the opening match of the day on Rod Laver Arena.

Extending the tournament to 15 days this year and scheduling only two matches in each day session was meant to avoid the sort of early-morning finishes that have become increasingly common.

But there have only been two days out of 10 so far where play has finished by midnight, and Daniil Medvedev and Emil Ruusuvuori played until 3.39am in their second-round clash.

Tuesday’s delay meant women’s defending champion Aryna Sabalenka did not start her match, which had been due to begin at 7pm, until 9.10pm, and Jannik Sinner and Andrey Rublev were not hitting their first balls until after 10.40pm.

Discussions took place about potentially moving one of the night session matches to a different court, but that ultimately did not happen.

Fritz said: “It just screws up your whole clock. I pray for those guys. I get it, matches go long some days. Like, today in particular, my match was long, the match before us was really long.

“But there’s got to be something they can do where people aren’t playing until 2, 3am, because I don’t think people really fully understand how much time we actually have to spend doing stuff after we finish playing. If you finish at 2am, there is no chance I’m going to sleep until 5, 6am.”

Wimbledon is unique in having an 11pm curfew, but play at the other grand slams has no cut-off point, and, with the average length of matches increasing markedly in recent years, what was rare in now commonplace.

Djokovic said: “We’ve seen in the past some late finishes. And I know for the crowds and for the tournament in a way it’s kind of exciting to see a 4am finish, a 3am finish. I was part of some of those. But it’s definitely not fun for us.

“The good thing about the quarter-finalist on the men’s section is we have two days. So I think that’s plenty of time to get a good sleep and recover.”

Djokovic will also need time to recover after battling past Fritz and into the semi-finals in Melbourne for the 11th time.

The world number one has never lost here once he has made it beyond the last eight, and there is no doubt how much he wants a 25th grand slam title.

Djokovic had beaten American Fritz in all eight of their previous meetings but this was certainly not straightforward. The first game alone lasted 16 minutes and the first set 84 minutes as they toiled in the heat.

Fritz, looking to reach a slam semi-final for the first time at the third attempt, remarkably saved all 15 break points he faced in the opening two sets, and he impressively levelled the contest.

It was just the third set he had won against the Serbian, with the other two both coming in a third-round clash here in 2021, when Djokovic suffered an abdominal injury but still managed to win in five.

But Djokovic began to turn the screw in the third set as Fritz started to feel his left foot, and successive breaks in the fourth set him on the way to a record-extending 48th slam semi-final.

Speaking to Nick Kyrgios on court, Djokovic said: “I suffered a lot in the first couple of sets. Also due to his high quality tennis. He was really kind of suffocating me from the back of the court.

“It was really difficult to find the right timing, it was really hot while the sun was still out. We all know Taylor has got one of the best serves in the world. I knew the kind of a threat he poses when he serves on such a high quality.

“Conversion of the break points was really poor but I managed to break him when it mattered. I think I upped my game midway through the third set all the way through to the end.”

Fritz was left with mixed feelings, saying: “I played a really high level for the first two sets, and they were a physical, tough two sets. It was like two and a half hours by the time we finished the two sets. I need to get to the point where I can do that for five hours.”

Coco Gauff and Aryna Sabalenka will meet in a rematch of the US Open final on Thursday for a place in the Australian Open trophy decider.

While seeds have fallen around them, Gauff and Sabalenka have made it through to the last four for what feels like a de facto final.

Fourth seed Gauff survived her first test of the tournament, needing three hours and eight minutes to defeat unseeded Ukrainian Marta Kostyuk 7-6 (6) 6-7 (3) 6-2.

Defending champion Sabalenka, though, continued her record of not having dropped more than three games in a set with a swift 6-2 6-3 win against ninth seed Barbora Krejcikova.

The start of the night session was delayed by more than two hours because of long matches in the day, but that did not affect Sabalenka, who said: “I think it was really a great match today, I think I played really great tennis and I hope I can keep playing that way or even better.”

The Belarusian lifted her first slam trophy here last year and has been the most consistent female player on the big stage, reaching at least the semi-finals at every major since.

She was favourite to win another title in New York but Gauff turned the tables after losing the first set to claim a 2-6 6-3 6-2 triumph and lift her first slam trophy.

The 19-year-old American is through to the last four here for the first time, but it was a real struggle, with Gauff and Kostyuk committing 107 unforced errors between them.

Gauff trailed 5-1 in the opening set before fighting back to win it, saving two set points.

She served for the match at 5-3 in the second set but now it was Kostyuk’s turn to surge back, and it was not until the third set that Gauff took control of the match, opening up a 5-0 lead.

The teenager is the youngest American to reach the women’s semi-finals in Melbourne since Mary Joe Fernandez back in 1991, and she is two wins away from making it back-to-back slam titles.

“It was a fight,” said Gauff. “I think today was definitely a C game, so I didn’t play my best tennis, but I’m really proud that I was able to get through today’s match. Hopefully got the bad match out of the way and I can play even better.”

Kostyuk, 21, was immediately able to put the result into perspective, saying: “I think it’s just a tennis match. I’m here to grow, to learn, to be better.

“I’m very proud of myself. I won for myself today, and I think it’s the most important thing. It’s just the beginning of the season. I’m looking forward for what’s ahead.”

Kostyuk and countrywoman Dayana Yastremska both made the last eight – Yastremska may yet go further – while Elina Svitolina reached the fourth round, and all have used the opportunity to highlight the ongoing plight of Ukraine.

“I think the girls did really well,” said Kostyuk. “I hope we will be able to succeed in most of the tournaments, especially the big ones where there is a lot of media. I think people should be reminded.

“I was texting with some people from Kyiv. I said, ‘How is it? How are you guys?’ They said, ‘Well, we were looking between your score and where the missiles are flying’. So it’s still there. My parents are still there. My sister is still there.”
