Andy Murray does not believe night matches dragging on into the early hours is beneficial to anybody.

Murray came back in stunning fashion at the Australian Open in a second-round match that started late on Thursday but dragged well into Friday in Melbourne.

The former world number one reached the third round with a marathon 4-6 6-7 (4-7) 7-6 (7-5) 6-3 7-5 victory over Thanasi Kokkinakis.

At five hours and 45 minutes, the five-set thriller was the longest match of Murray's career and the second-longest in Australian Open history, as the Briton claimed victory shortly after 04:00 local time.

Murray, though, sees no benefit of playing so deep into the night.

"I don't know who it is beneficial for," he said in a press conference. "We come here after the match, and that's what discussion is [about], rather than it being [on an] epic match.

"It ends in a bit of a farce. Amazingly, people stayed until the end. I really appreciate people doing that, creating an atmosphere for us.

"Some people need to work the following day. If my child was a ball kid for a tournament [and] they are coming home at five in the morning, I'm snapping at that.

"It's not beneficial for them, it's not beneficial for the umpires, the officials. It's not good for the players. We talk about it all the time. When you start the night matches, these things are going to happen."

Murray's career appeared to reach a potential end at this very tournament four years ago due to his longstanding hip issues, and it is a testament to his determination that he remains capable of going the distance in matches.

But he acknowledged there could be a health risk from long encounters such as this one, adding: "Potentially. It's strange because the courts are fast.

"When we started tonight, it felt like there was no pressure in the ball. It's just difficult to hit winners. There was a 70-shot rally yesterday, which is not normal. [We] probably need to look at that."

Kokkinakis was blunter in his assessment, posting on Twitter: "This f****** sport, man."

Murray, a five-time finalist in Melbourne, will face Roberto Bautista Agut in the third round, having progressed to that stage of the Australian Open for the first time since 2017.

Andy Murray made a record-breaking fightback in the longest match of his career to beat Thanasi Kokkinakis in an Australian Open thriller in the early hours of Friday morning.

After finding himself two sets down, Murray drew on the fighting spirit he has produced so many times over the years to secure an incredible 4-6 6-7 (4-7) 7-6( 7-5) 6-3 7-5 win on Margaret Court Arena.

The battling Brit came off the ropes to become he first player in Open era history to win 10 grand slam matches from two sets down.

With the clock having ticked past 4am local time, the 35-year-old finally triumphed in what was the second-longest match (five hours and 45 minutes) in Australian Open history, only beaten by the 2012 final between Novak Djokovic and Rafael Nadal (five hours and 53 minutes). 

Here, Stats Perform takes a closer look at some of the numbers from Murray's incredible win.

Murray's unbeaten grand slam streak against Australian players continues

Murray's success over Kokkinakis ensured his unbeaten record against Australian opponents at majors remained intact, making it 12 out of 12.

The former world number one has lost all five of his finals at the Australian Open, but he is now into the third round at the tournament for the first time since 2017.

His victory over Kokkinakis made him just the fifth male player in the Open era to win more than 50 main-draw matches at the Australian Open, joining illustrious company in Roger Federer, Djokovic, Nadal and Stefan Edberg.

Murray's greater experience shows against big-serving opponent

Kokkinakis seized control of the match by taking the first two sets, but as Murray dragged the contest into the later stages, the Brit's experience in big matches showed.

The 37 aces fired down by Kokkinakis was his highest career tally in an ATP-level main-draw match and 27 more than Murray served up. Kokkinakis racked up an astonishing 102 winners to Murray's impressive 69.

Three-time grand slam champion Murray became just the seventh male player to feature in 250 grand slam main draw matches, roaring back to surpass Todd Martin and Federer for the most major victories from two sets down. It was his first such triumph at the Australian Open.

Murray has now won both meetings with Kokkinakis, after also defeating him in the 2015 Davis Cup, and sets up a third-round clash with Roberto Bautista Agut, with whom he holds a 3-3 head-to-head record.

Andy Murray could scarcely believe he managed to fight from two sets down to topple home favourite Thanasi Kokkinakis in five sets at the Australian Open.

In an epic match that began on Thursday but ticked well into the early hours of Friday in Melbourne, Murray prevailed 4-6 6-7 (4-7) 7-6 (7-5) 6-3 7-5 in the second-longest match in Australian Open history.

With the clock having ticked past 04:00am local time, the five-time finalist finally triumphed to become the first player in Open era history to win 10 grand slam matches having lost the opening two sets.

"I don't know. Unbelievable that I managed to turn that round," said Murray, who has reached the third round of the Australian Open for the first time since 2017.

"Thanasi was serving unbelievable. I don't know how I managed to get through it. Yeah, I have a big heart.

"I'm aware I don't look particularly happy when playing but I'm at my happiest on the inside.

"I've always loved competing and always showed my emotions when I've played. I've been criticised a lot for it over the years but that's who I am."

Finally, in a message to the fans that stuck around at Melbourne Park, Murray said: "Thanks so much to everyone for staying. It's ridiculously late. You didn't need to do that but it really helps me and Thanasi when we have all of you creating an amazing atmosphere. I think we should all get off to bed now."

Kokkinakis was in cruise control when he doubled his lead with a tie-break victory in the second set.

But he then appeared to start feeling the pressure in the third set, smashing his racquet following an angry dispute with the umpire after receiving a time violation.

Taking advantage of his opponent's loss of composure, Murray battled back from 5-2 down to force another tie-break, where Kokkinakis lost four points on his serve as the match was pushed to a fourth set.

Having been one game from defeat, the tide was turning in Murray's favour, as he teed up a decider that had looked so unlikely.

Murray spurned his first seven break points but brilliantly won his eighth attempt with the set tied at five games apiece, putting the former world number one on the verge of a stunning success.

He made no mistake as he clinched victory with a forehand winner, ending the match after five hours and 45 minutes.

Only the 2012 final between Novak Djokovic and Rafael Nadal (five hours and 53 minutes) beating it in terms of longevity in the tournament's history.

Novak Djokovic described his hamstring injury as "not good at all" after the muscle caused him fresh concern during a second-round win at the Australian Open.

The nine-time Melbourne Park champion needed off-court treatment in set two of his match against French qualifier Enzo Couacaud.

He lost that set, but Djokovic was able to step it up to complete a 6-1 6-7 (5-7) 6-2 6-0 victory over the world number 191.

Speaking afterwards, Djokovic was asked about the left hamstring and painted a bleak picture.

He told Eurosport: "It's not good at all, to be honest with you. I take it day to day. It was better last match, the feeling, than tonight.

"It's really up to God to help me, and the physio and everyone. I hope I'll be able to recover and be ready for a tough match-up next match."

Grigor Dimitrov awaits Djokovic in round three, with the Bulgarian a tricky customer, albeit one who trails 9-1 in the rivalry between the pair.

Djokovic's latest win, his 23rd match victory in succession at the Australian Open, was nothing if not eventful, with Couacaud turning his ankle early on and looking in danger of having to abandon the biggest match of his career.

Later on, Djokovic demanded the umpire take action after claiming rowdy fans were distracting him by shouting out.

"There was a lot happening in tonight's match," Djokovic said in an on-court interview.

"Enzo deserves credit for the fight. He played some great tennis, especially in the second set. I managed to respond well in the third and especially in the fourth. Let's keep it going."

Novak Djokovic avoided becoming the latest Australian Open seed to fall as he survived an injury scare to see off French qualifier Enzo Couacaud.

After Casper Ruud, Alexander Zverev and Taylor Fritz were all sent packing earlier on Thursday, the question was whether Djokovic would become the ultimate casualty on a day of shocks.

The nine-time champion was troubled by his left hamstring problem during the second set, which went the way of world number 191 Couacaud, but Djokovic reasserted himself to secure a 6-1 6-7 (5-7) 6-2 6-0 victory on Rod Laver Arena.

The Serbian became increasingly incensed by shouting from the crowd during the match, pinpointing one fan as a chief culprit and telling the umpire during the fourth set: "The guy is drunk out of his mind. I'm asking you what you're you going to do about it. You heard it at least 10 times; I heard it 50 times."

Djokovic appeared to be pointing towards a group in 'Where's Wally?' fancy dress, who were reacting as though they were enjoying the moment before being spoken to by tournament officials.

It was a surprise the match reached a fourth set.

Mauritius-born Couacaud turned his ankle in the fourth game of the contest and retreated to his chair, seemingly in tears as he looked to cover his face with his towel.

The 27-year-old received medical treatment, getting the ankle strapped up, and he gamely battled on, albeit struggling initially.

It was then Djokovic who needed an injury timeout in the second set, going off court when trailing 5-4 and feeling some discomfort in the hamstring that has been troubling him during the last fortnight.

Couacaud took advantage and won the set, but from that point on it became all Djokovic, as he moved through to round three.

Data Slam: Djokovic sets up Dimitrov clash

Next for Djokovic will be a battle with the 27th seed, Grigor Dimitrov. He described the Bulgarian as a good friend and said they were "Balkan brothers". The rivalry on the court has been emphatically one-sided between Djokovic and Dimitrov, though, with nine of their past 10 meetings having gone the way of the Serbian.

Dimitrov's lone win came on clay in Madrid in 2013, while it will be a third grand slam match between the pair, with Djokovic having notched up previous victories at the French Open and Wimbledon.

Casper Ruud followed Rafael Nadal out of the Australian Open and admitted his decision to play through much of December rather than have an off-season may have been a mistake.

The Norwegian second seed, who reached finals at the French Open and US Open last year, had been hoping for another deep run this fortnight, only to run into an in-form Jenson Brooksby.

After a 6-3 7-5 6-7 (4-7) 6-2 defeat in three hours and 55 minutes on Rod Laver Arena, Ruud was asked about his decision to head to Latin America for a lucrative exhibition jaunt with Nadal at the end of the 2022 campaign.

He planned to take a break in February instead, but can now begin that early after going out in round two in Melbourne.

The same goes for top seed Nadal, who was already heading for defeat to Mackenzie MacDonald on Wednesday before an injury compounded his misery.

Ruud's initial reaction to being questioned about his busy December was to be defensive, saying: "It's very easy to sit here now and say that was bad for maybe both Rafa and I due to the fact that we lost early here.

"At the same time, I see no reason why we couldn't have a good Australian Open or made better results down here. I think it's coincidental sometimes."

He spoke of the talent among fellow tour players making every player vulnerable, and the "small margins" between victory and defeat.

Asked whether he had any break at all, Ruud outlined how he left for the Latin America trip on November 21 and returned in early December, before heading off on a week's holiday to the Maldives. He then stopped for a training block in Abu Dhabi on the way home and played two matches at the Mubadala exhibition event.

At the end of this season, Ruud might insist on a longer break and a focused training block.

"It was maybe not enough to be able to perform well here this year," Ruud said. "So it will be considered by me and my team what we will do in December this year, and if this was the right way to prepare for Australian Open or not.

"Maybe it looks like it was not the right way, but there are many factors that come into play. I have done what I felt was the right preparation but wasn't able to perform and win as many matches as I hoped here this year."

Taylor Fritz and Alexander Zverev were sent packing from the Australian Open as wildcard Alexei Popyrin and lucky loser Michael Mmoh sprang major shocks.

Australian Popyrin said he was living a dream after beating the fancied Fritz in an epic second-round match lasting four hours and two minutes on John Cain Arena.

American Mmoh, whose mother has Australian citizenship, knocked out former world number two Zverev just moments later on Margaret Court Arena.

Their exits followed the shock defeat for second seed Casper Ruud earlier in the day, as Novak Djokovic's half of the draw lost a host of big names.

Wildcard Popyrin won 6-7 (4-7) 7-6 (7-2) 6-4 6-7 (6-8) 6-2 against American eighth seed Fritz, revelling in the chants of "Popy" from the crowd afterwards.

The 23-year-old was close to tears, his voice breaking, after reaching the third round of a grand slam for the fifth time.

"This win, it means so much to me," Popyrin said. "I had the toughest year last year, didn't win many matches. I've won as many matches this year as I won in the whole of last year, and it's only January.

"Pre-season I put my head down and worked as hard as I could. I don't want that feeling I had last year ever again.

"I wrote that down to myself in my head, and I'm going to keep working, I'm going to keep pushing, I'm going to keep trying to go all the way."

Addressing the crowd, Popyrin added: "I love this feeling. I want more of this feeling. I want you guys to have this feeling more. I love you guys so much, thank you."

He is coached by former top-20 star Xavier Malisse and felt the Belgian's influence against Fritz.

"I was playing four hours, and me and my coach were locked in, it was like two against one against Fritzy. We had the same thoughts all the time," Popyrin said. "This is the dream for me and I don't want to wake up at all."

Mmoh was beaten by Aleksandar Vukic in the final round of qualifying but received a call into the draw at the last minute, after a late withdrawal, allowing him to cancel a flight home.

The world number 109 will face fellow American JJ Wolf next, for a place in round four, having ousted 12th seed Zverev 6-7 (1-7) 6-4 6-3 6-2.

Mmoh's father, Tony, represented Nigeria and won a match at the Australian Open in 1988.

"Life is crazy," Mmoh said. "Right when you think everything is looking dim, everything is looking dark, there's light at the end of the tunnel.

"My week is proof of that. I could easily have been in the States, was ready to be in the States, had my bag packed, my flight booked, I was meant to leave yesterday morning. The fact I'm playing Margaret Court is insane.

"If you look at my box over there, there's about five to seven Aussies. I used to come every single Christmas to visit them, unfortunately my mum couldn't be here, I feel like I'm half Australian because of them and I love you guys. This is like my second home now so might as well make it a homecoming.

"It's the biggest win of my career hands down. Coming out I felt the nerves a little bit. I settled down at the end of the first, and at that point I told myself I shouldn't even be here. I told myself on match point if I get a chance just go for it, because I shouldn't even be here."

Rafael Nadal faces up to eight weeks out of action with the hip flexor injury he sustained on his way out of the Australian Open.

The defending champion and top seed in Melbourne was bundled out 6-4 6-4 7-5 by world number 65 Mackenzie McDonald on Wednesday, struggling to move around the court during the closing stages of the contest.

He refused to retire and afterwards confirmed he aggravated an issue he had been suffering with for a couple of days. The 36-year-old Spaniard knew the problem he had been suffering with for a "couple of days" had worsened, but he was unsure exactly what was causing it.

Now Nadal has clarity, receiving details of the injury after tests on Thursday.

He knows that provided all goes to plan, he should be back on court for the clay-court stretch in Europe leading up to the French Open, where the 14-time winner is also the defending champion.

Nadal wrote on Twitter: "Good afternoon. I have carried out medical tests after the defeat yesterday. The MRI shows a grade two lesion in the iliopsoas of the left leg. Now it's sports rest and anti-inflammatory physiotherapy. Normal recovery time six to eight weeks."

The 22-time major winner may struggle to get back to full fitness in time for the Indian Wells and Miami Masters 1000 events in March.

Those are due to be preceded on his schedule by a high-profile exhibition match in Las Vegas against Carlos Alcaraz on March 5; however, both men are presently injured, raising doubts over whether that will go ahead.

Nadal was distraught to suffer yet another injury setback, after severe foot and abdomen problems hit his 2022 season.

"In terms of sports and in terms of injuries and tough moments, I mean, that's another one," Nadal said on Wednesday. "I can't say that I am not destroyed mentally at this time, because I will be lying."

Casper Ruud made two grand slam finals last year, but his 2023 Australian Open campaign fell to pieces with a shock second-round loss to 22-year-old Jenson Brooksby.

American Brooksby prevailed on his fifth match point, after fluffing three in the third set, when second seed Ruud hit a return long. That sealed a 6-3 7-5 6-7 (4-7) 6-2 victory in three hours and 55 minutes on Rod Laver Arena.

Ruud's demise on Thursday means he joins top seed Rafael Nadal in exiting early in Melbourne, with the Norwegian departing in the Spaniard's wake after struggling through the first two sets before a medical time-out prior to the third.

Ruud staved off three match points at 5-3 down in the third, when Brooksby got tight with victory in sight, before winning the set in a tie-break.

However, Brooksby regained his composure in the fourth set and broke twice early to open up a 3-0 lead, barely looking back.

Brooksby's triumph is the biggest of his career, having only ever previously beaten one top-10 player, Stefanos Tsitsipas, at last year's Indian Wells. It also provides an early highlight in Brooksby's first Australian Open, having missed out in 2022 after testing positive for COVID-19 on the eve of the tournament.

"I was just really proud of my mental resolve after that third-set battle didn’t go my way," Brooksby said during an on-court post-match interview. "I thought I was playing really strong. I didn’t want to lose my focus out there."

Ruud, who was the runner-up at both the 2022 French Open and 2022 US Open, could not match Brooksby's 50 winners, while the Norwegian committed 55 unforced errors. He also failed to capitalise on Brooksby's unconvincing 57 per cent first-serve percentage.

Data Slam: Americans maintain winning form in men's singles

Brooksby's triumph sets up a third-round date with compatriot Tommy Paul as the Americans continue to make waves in the men's singles draw. It was another American, Mackenzie McDonald, who upset Nadal on Wednesday, while a flood of US stars have reached the third round.

Mackenzie McDonald produced one of the upsets of the Australian Open on Wednesday as he eliminated defending champion Rafael Nadal 6-4 6-4 7-5 in the second round, with the Spaniard hampered by an apparent leg injury.

There were ominous signs early on as number one seed Nadal had his serve broken in the opening game of the match, and McDonald secured a second break en route to wrapping up the first set.

It was more of the same in the second as McDonald took advantage of some uncharacteristically sloppy play from the 36-year-old, before Nadal seemed to hurt himself.

At 4-3 down in the second set, Nadal pulled up with an apparent upper leg issue after chasing a forehand, and his movement was clearly hampered from that point on.

In typical defiant fashion, Nadal's level rose in the third, hitting 24 winners, but as he improved, so did McDonald, who did not allow Nadal a single break point opportunity.

The 22-time grand slam champion saved break point at 4-4 to hold serve as he tried to get back into the contest, but was unable to repeat the trick in his next service game as McDonald secured the break before serving out to clinch a famous win.

It is the latest in a troubling run of form for Nadal, who received multiple injury timeouts on his way to a seventh loss from his last 10 matches dating back to the US Open.

McDonald will play the winner of Yoshihito Nishioka and Dalibor Svrcina in the third round.

Data Slam: Nadal joins dubious company as top-seed casualty

Nadal is the first top seed to be eliminated from the Australian Open in the second round since Gustavo Kuerten in 2001.

Novak Djokovic set off on his Melbourne mission to match Rafael Nadal's haul of 22 grand slams, promising: "I know how to handle it."

The title favourite and nine-time champion swept through his first Australian Open match in two years, beating Spain's Roberto Carballes Baena 6-3 6-4 6-0.

Deported from Melbourne last year amid a vaccination saga, and denied the chance to defend his title, Djokovic received a rousing welcome on Rod Laver Arena.

"I felt very welcome on the court," Djokovic said. "Especially the Serbian community that is big here in Australia has welcomed me in an incredible way. So much support. So much love."

The 35-year-old from Belgrade dropped just four points in the closing set, with the hamstring injury that hampered his preparation seemingly giving him no fresh cause for concern.

"The leg is good. It's not ideal, but it's getting there. Today was a really good test," he added.

Djokovic will join Nadal at the top of the men's all-time list of slam triumphs should he pick up a 10th title at Melbourne Park next week. He may soon be looking at overtaking Margaret Court, who won 24 singles slams, the most by any player.

"They're just numbers in the end of the day," Djokovic said, when asked about the targets in his sights.

"I've been in the situations before where I've played for some really big historic things, and I've been blessed to have I would say more success than failures in those particular situations.

"I know how to behave, I know how to handle it. Let's see how far I can go."

Mother Dijana and father Srdan have joined Djokovic in Australia this year, as has brother Marko.

His parents have not made the trip to Melbourne since 2008, the year Djokovic won a first grand slam in Australia.

"Well it's really not around the corner from Serbia. Australia is a pretty long way," said Djokovic, explaining why they usually stayed away.

"That's probably the biggest reason. They've come to watch me in Paris, Roland Garros, and Wimbledon, US Open. In particular, Australian Open has been a bit of a trip for my parents particularly.

"I'm really glad to have them here. The last time they were here, actually the only time they were here, was back in 2008. We have some great memories and considerations about the time that they spent here together now 15 years ago. Hopefully they can stay all the way, I can stay all the way, and we can have another great celebration."

Novak Djokovic swept through his first Australian Open match in two years as his mission to create more tennis history began in impressive style.

Chasing a 10th Australian Open title, and the major that would take him level with Rafael Nadal's record of 22 men's singles grand slams, Djokovic beat Roberto Carballes Baena 6-3 6-4 6-0.

Deported from Melbourne last year amid a vaccination saga, and denied the chance to defend his title, Djokovic received a rousing welcome on Rod Laver Arena.

The contest did not begin until shortly after 2230 local time, with Andy Murray's five-set afternoon battle against Matteo Berrettini having been followed by a three-set struggle for Ons Jabeur in the first night match.

Djokovic began with an ace, but all eyes were on how he would cope with a left hamstring problem that has been affecting his preparation. It required strapping, but ultimately it did not prove a worrying factor.

Entering the contest, world number 75 Carballes Baena had a 0-9 career record against top-10 players, so the match went much as expected.

The underdog had three break points in the fifth game but could not capitalise as Djokovic came from 0-40 behind to stay on serve. There was no escape from 0-40 for Carballes Baena in the next game, though, as Djokovic sealed the first break with a brutally brilliant forehand.

That established the tone, with Djokovic breaking in game seven of the second set on his way to a firm stranglehold. Once the second set was won, Djokovic steamed through the third, dropping only four points.

Data slam: Never in doubt

Djokovic is now 67-2 in grand slam first-round matches. His only losses have come in Australia, against Marat Safin in 2005 and Paul Goldstein a year later.

Alexander Zverev believes the Australian Open is already a success for him after his five-set victory against Juan Pablo Varillas on Tuesday.

It was the German's first win since his foot injury at the French Open in June during his semi-final against Rafael Nadal.

Zverev only returned to tour-level tennis in December at the United Cup, where he lost to Jiri Lehecka and Taylor Fritz.

He fell a set behind twice against the Peruvian lucky loser Varillas, before fighting back to win 4-6 6-1 5-7 7-6 (7-3) 6-4.

The world number 12 hit 69 winners and won 83 per cent of his first serve points in the contest, which lasted four hours and nine minutes.

"I am extremely happy because I missed this over the past seven months," Zverev said after his victory.

"This match alone pays off for all the hard work and suffering that I have had. To win in front of this kind of crowd again.

"I can't wait for the rest of the tournament. No matter what happens from now, the tournament is already a success for me."

Zverev will face the winner of Michael Mmoh or Laurent Lokoli in the second round, with their match suspended at two sets all on Tuesday due to rain.

Andy Murray savoured a landmark win at the Australian Open as Tuesday's five-set triumph against Matteo Berrettini gave him a 50th career victory at Melbourne Park.

The world number 66, formerly an ATP rankings leader, slugged out a 6-3 6-3 4-6 6-7 (7-9) 7-6 (10-6) success against 13th seed Berrettini, who reached the semi-finals last year.

It handed Berrettini a first opening-round exit at a grand slam since the 2019 Australian Open.

Murray said he "wouldn't expect to feel perfect" for his next match on Thursday, given the effort that went in over the four hours and 49 minutes on Rod Laver Arena.

However, the 35-year-old, who will face Fabio Fognini or Thanasi Kokkinakis next, will want to be back to somewhere near full health for that tussle.

Last year in Australia, Murray beat 21st seed Nikoloz Basilashvili in another gruelling first-round five-set marathon, before losing tamely to Japanese qualifier Taro Daniel in his second match.

In all, Tuesday's scalp of Berrettini gave Murray his fourth five-set win at the Australian Open. The other two came in semi-finals, beating Roger Federer in 2013 and Milos Raonic three years later. He lost in the subsequent final both times to Novak Djokovic.

Djokovic has beaten Murray in four Australian Open finals, with the Briton also sunk by Roger Federer in the 2010 title match, meaning he has been runner-up five times and never come away with the trophy.

Federer has won the most men's singles matches in Australia, with 102 victories, landing six titles along the way. Djokovic, with nine, has the most titles.

A weary Murray said after finishing off Berrettini: "In the last few years, I've certainly questioned myself at times. There's certainly a lot of people who have questioned me and my ability, whether I could still perform at the biggest events and the biggest matches.

"I felt very proud of myself after the match. That's not something that I generally felt over the years at the end of the tennis matches.

"I was impressed with myself, which again is not something... I'm hard on myself usually."

Andy Murray pulled off a stunning victory over Matteo Berrettini at the Australian Open as the five-time runner-up enjoyed another big moment in Melbourne.

Unseeded this year, former world number one Murray survived a match point against him to take a first-round thriller against the Italian 13th seed.

Murray had not lost a grand slam match after winning the first two sets since a third-round clash against David Nalbandian at Wimbledon in 2005, his first grand slam main-draw appearance.

Yet he almost let such a lead slip away this time, before digging deep for a 6-3 6-3 4-6 6-7 (7-9) 7-6 (10-6) victory, achieved in four hours and 49 minutes.

Five-time Australian Open runner-up Murray faced a daunting opener, but both men would have hoped for a kinder draw.

It seemed to be going firmly the 35-year-old Scot's way when he swept through the opening two sets, but back came Berrettini to level up, edging a tight fourth that could have gone either way.

Berrettini had the contest at his mercy at match point against Murray's serve at 5-4 in the decider, only to clatter a close-range backhand into the net when it seemed sure he would put away a winner.

The stakes were high as the match entered a final-set tie-break, and when Murray sped into a 5-0 lead he looked firmly in control. There were slight wobbles from that point, but Murray made sure, helped by a lucky net cord on match point as a service return trickled over.

"I didn't know that," Murray said afterwards, when told about his record when leading matches by two sets.

Berrettini lost his first meeting with Murray, which came in Beijing in 2019, but the Italian won all three of their next matches, on grass at London's Queen's Club and Stuttgart before a US Open victory last September.

Former Wimbledon and US Open winner Murray, still playing thanks to his metal hip, expects Tuesday's match on a scorching day in Melbourne to take a toll. 

"I'll be feeling this, this evening and tomorrow, but right now I'm unbelievably happy, very proud of myself," Murray said in an on-court interview.

"I've put a lot of work into the last few months with my team who are here to give me an opportunity to perform on stadiums like this and matches like this, against players like Matteo, and it paid off tonight."
