Novak Djokovic kept his bid of a record 25th grand slam title alive as he battled injury and fought from a set down to defeat young rival Carlos Alcaraz and win an epic Australian Open quarter-final 4-6 6-4 6-3 6-4.

Djokovic backed up his sensational victory over the 21-year-old Alcaraz in the Olympics final with a remarkable comeback in Melbourne, with the 37-year-old having struggled with his left leg in the early stages of the match.

He left the court for a medical timeout but returned to find an inspired level of attacking play, tormenting Alcaraz on the returns while withstanding the Spaniard on the defence in a stunning display of his remaining powers.

Djokovic’s bid to become the oldest grand slam champion of all time does not get any easier: he will face second seed Alexander Zverev in the semi-finals, with defending champion Jannik Sinner still on the other side of the draw as well.

And he admitted he was left “concerned” by his upper leg injury and said he does not know what condition he will be in ahead of Friday’s semi-final. “If I manage somehow to be physically good enough, I think mentally, emotionally I’m as motivated as I can be,” Djokovic said.

Meanwhile, Aryna Sabalenka also prevailed in a tough battle against Anastasia Pavlyuchenkova and the defending champion will face Paula Badosa in the semi-finals. Badosa ended Coco Gauff’s winning run to reach her first grand slam semi-final.

The moment Carlos Alcaraz let Novak Djokovic mount an epic, improbable Australian Open comeback

18:17 , Jamie Braidwood

When Carlos Alcaraz saw his great rival Novak Djokovic limp off the court towards the end of the first set of their blockbuster Australian Open quarter-final, the 21-year-old admitted to feeling a sense of relief. Alcaraz’s experience of the Olympics final at Roland Garros, where Djokovic raised his level to win his elusive gold medal last summer in a hugely emotional defeat for the young Spaniard, ensured he needed no reminder of how fearsome an opponent the 37-year-old remains when fully fit.

But as Djokovic struggled to move from side to side, let alone return his groundstrokes on the run or hit through his opponent from the back of the court, Alcaraz’s shoulders relaxed. Djokovic, head down, exited the Rod Laver Arena for a medical timeout, returning after several minutes with heavy strapping around his upper left leg. A few moments later, Alcaraz wrapped up the first set; having beaten Djokovic in consecutive Wimbledon finals over best-of-five, it looked a long way back for the 10-time Australian Open champion.

But Alcaraz will not forget what happened next.

Novak Djokovic hits back to beat Carlos Alcaraz in Australian Open thriller

17:45 , Jamie Braidwood

Novak Djokovic proved himself the Melbourne Park master once again with a brilliant late-night victory over young pretender Carlos Alcaraz.

The 10-time Australian Open champion is only two wins away from a record-breaking 25th grand slam title after a 4-6 6-4 6-3 6-4 success completed at 12.57am that will have put the whole locker room on notice.

A potential concern for Djokovic, who next plays second seed Alexander Zverev in what will be his 50th slam semi-final, is a left leg problem that required treatment during the opening set, but he seemed to improve physically as the match went on.

Novak Djokovic reveals meaning behind Andy Murray celebation

17:17 , Jamie Braidwood

Novak Djokovic reveals why he turned to celebrate with Andy Murray after winning match point against Carlos Alcaraz.

“I feel more and more connected with Andy every day. We face challenges every single day. People don’t see that obviously.

“We try to make the most out of every day and grow together. He’s been as committed to my career and this tournament as he can be.

“So it was kind of a gesture of appreciation, respect for him, and the fact that he’s out there, and he doesn’t need to be.

“He accepted to work with me. He’s giving all his support to me, to the whole team, and trying to make it work.

“This was a huge win for all of us, including Andy and myself, you know, for the relationship. Yeah, that’s why I went to him, because I just felt very grateful that he’s there.”

Novak Djokovic ‘concerned’ by injury ahead of Australian Open semi-finals

16:46 , Jamie Braidwood

Novak Djokovic admitted he is “concerned” by his left leg injury as attention now turns to Friday’s Australian Open semi-final against Alexander Zverev.

“I have to assess the situation tomorrow when I wake up. I will try to do as much as I possibly can with my recovery team, with my physio today, tomorrow, the next few days. Probably skip training tomorrow.

“I’ll see if I’m going to train in two days or not. I’ll take it day by day. Now it’s really about recovery.

“I’m concerned. I am, to be honest, physically. But if I manage somehow to be physically good enough, I think mentally, emotionally I’m as motivated as I can be.

“This match drains both players. Almost three and a half, four hours of incredible battle, of high intensity, of course it has its toll.

“At the same time I think it has more toll on the physical side rather than mental and emotional. Actually it feels like you’re feeding off this kind of win.

“That’s how I feel now. I hope to be able physically to be moving freely and to be able to be ready to play five sets.”

Novak Djokovic responds to Carlos Alcaraz comments: ‘I saw it’

16:16 , Jamie Braidwood

Novak Djokovic’s response when told Carlos Alcaraz admitted he lost focus when he saw his opponent was struggling with injury in the second set.

“I saw it. I try to use that to my advantage, in a sense, to take the initiative of the rallies and his hesitation. He was trying to play at some point quite a few dropshots and make me run.

“I’ve been in the situations, as well, where opponent’s struggling with injury, but kept going. The opponent is going for everything, and then he’s staying in the match. Then all of a sudden as the match progresses, the opponent feels better. You’re starting to panic a bit with your game.

“I understand the feeling. Look, I feel for him. I understand that it’s not comfortable to play someone that you don’t know if he’s going to retire or not. Is he moving? Is he running? What’s happening? I felt that he was looking at me more than he was looking at himself.”

Carlos Alcaraz to leave Australian Open with ‘head up'

16:02 , Jamie Braidwood

Carlos Alcaraz says he will leave the Australian Open with his “head up” after taking pride in his performance against Novak Djokovic.

“I’m playing great, great matches,” he said. “I mean, every time that we play against each other, I think it’s a guarantee.

“We push us to the limit, each other. I think we’ve played great points, great rallies. It was really tight the third, the fourth set. I mean, the whole match, I guess.

“I’m just lucky to live this experience. I’m 21 years old. From these matches, I’m getting so much experience about how to deal with everything. I’m not going to hide.

“I’ve done great things in tennis already, but playing against one of the best in history of our sport, these kind of matches help me a lot in the future to be better.

“I’m just happy to be able to live this experience. It’s great hearing those words from someone who played historic matches and achieved historic things.

“I’m leaving here Australia with the head up. I’m really happy about hearing those words from Novak.”

Carlos Alcaraz admits he thought Novak Djokovic match was going to get ‘easier’

15:45 , Jamie Braidwood

Carlos Alcaraz admits he thought his quarter-final with Novak Djokovic was going to get “easier” when he saw his opponent was struggling with injury.

“When you are seeing someone that is struggling physically a little bit, it’s kind of you not playing the same level,” Alcaraz said.

“It seems like, okay, it’s going to be easier. At the same time in your mind you’re thinking, like, Okay, I have not to make mistakes.

“Probably you’re not hitting the ball at the same way that you’re hitting before. I think that’s it.

“I think he did great, great hits, great shots. He started to play more aggressively, try not to move so much in the second set.

“He made few of them, which make him stay up in the set, break up, or stay up. After that, as I said, it was really difficult to overcome that, and I’m playing better than him.”

Australian Open: Carlos Alcaraz reacts to his defeat to Novak Djokovic

15:31 , Jamie Braidwood

In his press conference, Carlos Alcaraz admits he should have pushed Novak Djokovic harder in the second set while the 37-year-old was stuggling with injury.

“Honestly, I felt like I was controlling the match, and I let him get into the match again. I’m going to say that’s was the biggest mistake that I made today.

“In the second set I had to play a little bit better just to push him even more to the limit. He had issues just moving a little bit in the second set. I had to push him a little bit more just to the limit, and I didn’t.

“After that, I think he started to feel better and playing such a great level. That was my biggest mistake today.

“But obviously when Novak is at this level, it’s really difficult. I think I had my chances. It was a really close match.

“I think most of the crucial points went to his side. When Novak is playing at this level, it’s really difficult to find the way.”

Australian Open: Novak Djokovic’s record against Alexander Zverev

15:01 , Jamie Braidwood

Djokovic made a joke in his on-court interview that he has an agreement with Alexander Zverev that he always beats him at the grand slams.

And he’s not wrong: Djokovic has won their three previous matches over best-of-five sets, including in the Australian Open quarter-finals in 2021.

He leads the head-to-head 8-4, but their last meeting came in 2021 at the ATP Finals. Zverev’s biggest win over Djokovic came in the Olympic semi-finals that year, when they met five times.

Australian Open: Djokovic calls Alcaraz match ‘one of the best matches I have played’

14:45 , Jamie Braidwood

Novak Djokovic, speaking to Eurosport, about playing through injury to beat Carlos Alcaraz:

“You don’t want to be playing with an injury, but you have to adapt to the circumstances and whatever you are facing on the court. It’s not the first time for me, here in 2021 and 2023 I had similar things. I played some of my best tennis after that. I have an extra day off and hopefully that will help.

“Once the body cools down, I will know what the reality is. It has been one of the best battles and matches that I have played on any court. I had to do better than I have done the entire tournament. I don’t know how I got out of that trouble towards end of the fourth set and I’m just super pleased to get through.”

Australian Open: More history and records on the line for Djokovic

14:31 , Jamie Braidwood

Novak Djokovic is now through to his 50th grand slam semi-final, and his 12th Australian Open semi-final.

He’s only lost one Australian Open semi-final, and that was last year to Jannik Sinner. Usually when he reaches this stage, he wins the tournament.

A 25th grand slam title, which would give him the outright singles record, remains possible.

Australian Open: Novak Djokovic on how injury changed his approach

14:15 , Jamie Braidwood

Djokovic stops his interview when he sees his kids are still on court at 1am local time!

“In 2023 I had a similar injury and carried it from the start of the tournament, I had to go for my shots more and sometimes it helps. We are so nervous on the court, we are going through emotional turmoil. Any point can shift the momentum, especially against a champion like Carlos.

“It was unfortunate what happened to me. But comparing it to 2023, it does help mentally. You have to play a bit more aggressive, I guess that is going to be necessary for me ahead of playing Zverev in the semi-finals.

“The key is recovery for me now. The extra day has come at a perfect time for me at the tournament. Let’s see if it’s going to be good enough on Friday. We have an agreement, as long as I keep playing he is going to let me win grand slam matches.”

Australian Open: Novak Djokovic on his injury

14:10 , Jamie Braidwood

“Since I am still in the tournament, I don’t want to reveal too much. The medication started to kick in.

“They helped, no doubt. I had to take another dose. If I’d lost that second set, I don’t know if I’d have continued playing.

“I felt better and better and managed to play a great couple of games at the end of the second set.

“Then I saw that Carlos was hesitant a little bit at the back of the court and I took my chances, started to feel better and move better.

“It didn’t bother me or create any hindrance towards the end of the match. When the medication starts to release, I’ll see what the reality is tomorrow morning.

“Right now I am just trying to be in the moment and enjoy this victory.”

Australian Open: Novak Djokovic on beating Carlos Alcaraz

14:07 , Jamie Braidwood

How on earth did Novak Djokovic win that? How did he find his best level at the grand slams, in over a year, after taking a medical timeout and struggling with injury in the first set?

Let’s ask him. He’s talking to Jim Courier on court.

“With my two legs and two arms, I guess. Or one and a half legs.

“First, I want to say my utmost respect and admiration for Carlos and everything he stands for and has achieved so far in his career.

“What a terrific guy he is and an even better competitor, the youngest No 1 in the world in history, four grand slams.

“I’m sure we are going to see a lot of him. He’s going to be there for sure longer than me. I just wish that this match today was the final, honestly.

“I don’t know if Sacha Zverev is still awake and watching this. One of the most epic matches that I’ve played on any court.”

Djokovic looks uncomfortable hitting on the run, and has done all match. A backhand is pushed wide and Alcaraz has 40-15 on serve.

Australian Open: *Carlos Alcaraz 5-4 Novak Djokovic

11:13 , Jamie Braidwood

Djokovic is back on court, with heavy strapping on his left leg.. But this is a major worry for the 37-year-old, who needs to be at his absolute best, physically, mentally and tactically, to beat Alcaraz. Playing with an injury is hardly ideal.

11:08 , Jamie Braidwood

One thing to watch out for: it’s approaching 10pm in Melbourne and this is not the sort of match that is likely to be wrapped up in a couple of hours... it’s going to be a late one for the locals, as well as Djokovic and Alcaraz. Tennis will tennis.

Australian Open: *Carlos Alcaraz 2-3 Novak Djokovic

Australian Open: Carlos Alcaraz 0-0 Novak Djokovic*

10:18 , Jamie Braidwood

Here we go! Rod Laver Arena crackles with excitement as Novak Djokovic and Carlos Alcaraz step out onto court, in the latest chapter of their epic, generational rivalry.

Djokovic is the 10-time champion here, but his winning run in Melbourne was put to an end by Jannik Sinner in last season’s semi-finals.

Alcaraz has beaten Djokovic in their last two grand slam matches but the 37-year-old won the biggest match of last year in the Olympics final.

But this is their first meeting at a hard court grand slam, with Djokovic winning both matches they’ve played at the ATP Finals and Cincinatti.

So.... who wins? The Australian Open ‘win predictor’ gives it to Djokovic, by 56%. He will serve first to start this quarter-final.

What has Carlos Alcaraz said about Novak Djokovic?

10:11 , Jamie Braidwood

“If I think about everything he has done in tennis, I couldn't play. I mean, 24 grand slam titles, the most weeks at No. 1, everything. He almost broke every record in tennis. I'm trying not to think about that when I'm in the match.

“I'm just trying to beat him. I know my weapons. I know that I'm able to play a good tennis against him, I'm able to beat him. That's all I'm thinking when I'm facing him.

“I think what every player or the best players think when they face Novak, just playing and believing in their-selves.”

Coach Andy Murray faces biggest test against Carlos Alcaraz

10:10 , Jamie Braidwood

When Novak Djokovic announced that he would be appointing Andy Murray as his coach for the Australian Open, it was for matches like today’s quarter-final against Carlos Alcaraz in mind.

Djokovic was beaten in both matches against Alcaraz and Jannik Sinner in the grand slams last year, and the 37-year-old was looking for something new to help defeat his young rivals over best of five sets.

He identified Murray as the solution. The former World No 1 knew Djokovic’s game from back to front, and had experience of facing Alcaraz and Sinner in ihs final months on the tour.

“He knows the evolution of my game, the weaknesses and strengths of my game,” Djokovic said. “He also knows the game, the tennis game, of the biggest players in the world right now because he has just recently retired as a player.”

Against Alcaraz, we will see what impact coach Murray may have.

What has Novak Djokovic said about Carlos Alcaraz?

10:09 , Jamie Braidwood

“I'm expecting a big battle, as it's the case in most of our matches where we faced each. other. Maybe just couple times it was quite one-sided Wimbledon finals last year, he was the dominant force on the court. I had a really good match against him in the World Tour Finals in 2023.

“Other than that, we had some long battles, long exchanges kind of matches that I played against him. Remind me of my matchups versus Nadal in terms of the intensity and the energy on the court.

“He's very dynamic, explosive player. Incredibly talented. Charismatic player. Great to watch; not that great to play against.”

Novak Djokovic receives apology from Australian TV presenter over ‘offensive’ comments

10:06 , Jamie Braidwood

An Australian TV presenter has publicly apologised to Novak Djokovic and Serbian tennis fans after the 10-time Australian Open champion boycotted his post-match interview on Sunday.

Djokovic revealed afterwards that his decision not to answer on-court questions in the customary manner following his fourth-round victory over Jiri Lehecka was in protest at comments made on host broadcaster Channel 9 by Tony Jones.

Jones mocked a group of chanting Djokovic fans behind him ahead of the Serbian’s third-round match by singing: “Novak is overrated, Novak’s a has-been, Novak kick him out.”

Djokovic is satisfied with the apology issued by Jones.

“Novak acknowledges the apology has been given in public as requested," read a statement issued Monday by Tennis Australia, "and is now moving on and focusing on his next match.”

Novak Djokovic vs Carlos Alcaraz head to head

10:05 , Jamie Braidwood

This will be the eighth match between Djokovic and Alcaraz and their fourth over best of five sets. Djokovic currently leads the head to head with four wins to three, and won their last meeting in an epic victory at the Olympics final.

While Alcaraz’s previous two wins over Djokovic have come in the Wimbledon final, in 2023 and 2024, this will be their first grand slam match played on a hard court, following a French Open semi-final in 2023.

Australian Open: GAME, SET AND MATCH!

10:00 , Jamie Braidwood

Aryna Sabalenka 2-6 6-2 6-3 Anastasia Pavlyuchenkova

Pavlyuchenkova threatened the big upset, but Sabalenka slams the door in the third set! The defending champion survives a scare to win for the 19th match in a row at the Australian Open, and moves on to the semi-finals.

She will play her good friend, Spain’s Paula Badosa, in the final four. That was a tough test, and Sabalenka dropped her first set since the 2023 final. But she is so hard to beat and that was an impressive recovery. The three-peat is still on.

Sabalenka is relieved. “Guys, I was praying,” she tells Jelena Dokic on court. “It was very difficult. She plays amazing tennis, super aggressive, I’m super happy to somehow, magically, win this match. Now you guys can enjoy the battle between Djokovic and Alcaraz.”

Australian Open: *Aryna Sabalenka 2-6 6-2 5-3 Anastasia Pavlyuchenkova

09:57 , Jamie Braidwood

The pressure weighs on Pavlyuchenkova and Sabalenka breaks to have the chance to serve for the match! Pavlyuchenkova’s level has come down a touch, and she faced big pressure points on her serve after the hot-streak on the winners cooled down. Sabalenka takes advantage with champion’s timing.

Now can she serve it out?

Australian Open: Aryna Sabalenka 2-6 6-2 4-3 Anastasia Pavlyuchenkova*

09:49 , Jamie Braidwood

Sabalenka rattles off eight points in a row on serve to steady the ship, putting some pressure on Pavlyuchenkova as we enter the business end of this quarter-final.

Has the momentum turned again?

09:40 , Jamie Braidwood

Strange! Pavlyuchenkova cracked a hole in the Sabalenka aura with another break, before playing her worst service game of the match and being broken to love. A major dip from the 27th seed.

BREAKS! Aryna Sabalenka 2-6 6-2 1-1 Anastasia Pavlyuchenkova

09:34 , Jamie Braidwood

A trade of breaks at the start of the second set, with both players showing their frustration after losing serve early in the decider.

It was key for Sabalenka to break back, though, after Pavlyuchenkova looked to try and maintain her momentum into the third.

The World No 1 battled through a testing deuce game, finding the backhand winner down the line and then forcing Pavlyuchenkova into the miss at the net.

Djokovic and Alcaraz watch on in the gym behind the scenes.

SET! Anastasia Pavlyuchenkova levels against Aryna Sabalenka 2-6 6-2

09:18 , Jamie Braidwood

Wow! Who saw this coming? Anastasia Pavlyuchenkova strikes back against World No 1 Aryna Sabalenka with a set of the highest quality. The 27th seed strikes 10 winners to just four unforced errors, blitzing Sabalenka’s game from the back of the court with clean, aggressive hitting.

Sabalenka didn’t do too much wrong. But she now faces a deciding set for a place in the semi-finals. It’s the first set she has lost since the 2023 final against Elena Rybakina. She had won 24 in a row.

Novak Djokovic: 'I believe I can win against any opponent'

09:08 , Jamie Braidwood

Novak Djokovic on his improving form ahead of facing Carlos Alcaraz in the quarter-finals:

“I think the last two matches have been really high level. I played two Czech players that are in a really good form.

“[Jiri] Lehecka won a tournament in the first week of the season. He's been feeling the ball great. It was a great matchup for me prior to Alcaraz. Of course, I wasn't thinking about Alcaraz before winning this match, which again I didn't see myself as a clear favourite.

“I'm really glad to be able to beat both [Tomas] Machac and Lehecka in straight sets. That encourages me to believe I can win against any opponent really on a good day when I'm feeling my best. That's what I'm trying to focus on, my game, recovery, making sure that I'm ready for whatever awaits me on the court.”

Anastasia Pavlyuchenkova hits back against Aryna Sabalenka

09:03 , Jamie Braidwood

Quite the turnaround on Rod Laver Arena as Anastasia Pavlyuchenkova claims the double-break in double-quick time to lead Aryna Sabalenka 4-1 in the second set.

The Russian is hitting big and is landing her explosive strikes to rush Sabalenka around the court. It looks like we’re heading for a third.

Novak Djokovic's path to Australian Open quarter-finals

08:59 , Jamie Braidwood

Novak Djokovic has been much sharper in rounds three and four after dropping sets in both of his opening victories against inexperienced opponents in Melbourne.

After admitting he was outplayed at times by American wildcard Nishesh Basavareddy and Portuguese qualifier Jaime Faria, Djokovic knew he had to wake up.

And he returned to form to dismiss the challenge of Czech threats Tomas Machac and Jiri Lehecka, and in convincing fashion, too:

R1: vs Basavareddy (WC) 4-6 6-3 6-4 6-2

R2: vs Faria (Q) 6-1 6-7 6-3 6-2

R3: vs Machac (26) 6-1 6-4 6-4

R4: vs Lehecka (24) 6-3 6-4 7-6

QF: vs Alcaraz (3)

Time on court: 11 hours

Carlos Alcaraz's path to Australian Open quarter-final

08:51 , Jamie Braidwood

The Spaniard’s route to the quarter-finals has been as smooth as could be. Alcaraz has dropped just one set, to Nuno Borges, and advanced against Jack Draper when the British No 1 retired at the end of the second set.

You could make an argument that Alcaraz has not been required to find his highest level so far, with the 21-year-old also deciding to miss the warm-up events and arrive straight at the Australian Open. He’s played more than three hours less than Djokovic.

R1: vs Alexander Shevchenko 6-1 7-5 6-1

R2: vs Yoshihito Nishioka 6-0 6-1 6-4

R3: vs Nuno Borges 6-2 6-4 6-7 6-2

R4: vs Jack Draper (15) 7-5 6-1 ret.

Time on court: 7 hours 45 minutes

FIRST SET! Aryna Sabalenka leads Anastasia Pavlyuchenkova 6-2

08:38 , Jamie Braidwood

Sabalenka breaks Pavlyuchenkova to win the first set 6-2 and looks to be closing in on a 19th consecutive victory at the Australian Open.

It’s going to take something special to stop the World No 1. It doesn’t look like that will be Pavlyuchenkova. But could it be Paula Badosa?

Australian Open: Aryna Sabalenka leads Anastasia Pavlyuchenkova 5-2*

08:32 , Jamie Braidwood

Aryna Sabalenka has raced into a commanding first-set lead against Anastasia Pavlyuchenkova in the second women’s quarter-final.

The World No 1 is a break up and Pavlyuchenkova makes two double faults in a row as she tries to hold to stay in the set.

The winner of this will face Paula Badosa in the semi-finals.

Alexander Zverev through to Australian Open semi-finals

08:15 , Jamie Braidwood

Alexander Zverev is through to the Australian Open finals for the second year in a row after riding his luck to beat American Tommy Paul.

Paul served for the first and second sets but Zverev broke back and then played excellent tiebreaks, eventually winning 7-6 (1) 7-6 (0) 2-6 6-1.

“I should have been down two sets to love,” Zverev said. “He played better than me, I was not playing great and I thought he was.

“I won the first set somehow, won the second set somehow. The fourth set was definitely the best I’ve played and I’m obviously extremely happy to be back in the semi-finals.”

Zverev will play the winner of the other quarter-final between Carlos Alcaraz and Novak Djokovic.

Paula Badosa halts Coco Gauff's winning run in Australian Open quarter-finals

08:10 , Eleanor Crooks

Paula Badosa ended Coco Gauff’s winning run to reach her first grand slam semi-final at the Australian Open.

The American third seed arrived in Melbourne as the most in-form player on tour after winning the WTA Finals to end last season and then all five singles matches at the United Cup, including a clash against Iga Swiatek.

She went into the clash with 11th seed Badosa on a 13-match winning streak but it was the Spaniard who came out on top in a 7-5 6-4 victory.
