For the first time in 20 years, four or fewer of the top eight seeds in the men's singles will progress to the fourth round of the Australian Open.

Daniil Medvedev's defeat to Sebastian Korda on Friday meant he joined Casper Ruud, Taylor Fritz and defending champion Rafael Nadal in heading home early from the season's first grand slam.

According to Opta, it is the first time since 2003 that the round of 16 in Melbourne will include four or fewer of the top eight players in the competition.  

Nine-time champion Novak Djokovic, meanwhile, is struggling with injury ahead of his third-round tie with Grigor Dimitrov on Saturday, while world number six and fifth seed Andrey Rublev faces a tough test against Dan Evans.

Stefanos Tsitsipas is sure of his place in round four after the Greek third seed beat Tallon Griekspoor in straight sets. Felix Auger-Aliassime will go up against Jiri Lehecka for a place in the last eight.

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.

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.

Vasek Pospisil has backed Novak Djokovic to win the Australian Open a year after the Serbian was unable to compete.

Djokovic was denied a place in last year's tournament when his refusal to have a COVID-19 vaccine led to him being detained in a Melbourne immigration centre and later deported.

With vaccination status no longer a condition of entry to the country, the nine-time Australian Open champion is back for this year's tournament, which begins on Monday.

Djokovic played doubles with Pospisil in his first match back in Australia earlier this month at the Adelaide International 1, and speaking to Stats Perform, the Canadian tipped his close friend to go all the way in Melbourne.

"I hope he wins it. I would consider him the favourite, absolutely," Pospisil said. "If you have to pick a favourite, it's hard to pick someone else.

"Having said that, obviously there are so many great players and incredible talents put together for one week, anything can happen, right? That's sport, but I would definitely put him as the favourite and if I had a choice if someone's winning other than myself, obviously, I would put him as the hopeful for the title.

"Also, given he had a tough, tough year obviously with what happened in the past."

Pospisil denied that the frustration of missing out last year would be a factor in Djokovic's motivation to do well this time, though.

"I think he's so motivated already with his ambitions in the sport and just in life in general," he added. "He's obviously a very driven individual, which is not something you need to hear from me to know, you can see that. I don't think it will necessarily be extra motivation.

"I feel like every time he's playing a grand slam, he's maximumly motivated. I do think he's going to have a great year and I don't think that anything that happened recently will affect him in a negative way.

"I think he showed that with how he played at Wimbledon last year [beating Nick Kyrgios in the final] just speaks volumes of his character and how strong he is an as an individual. It's very, very impressive that he was able to bounce back like that."

Pospisil, ranked 94th in the world, is also confident about his own prospects at the Australian Open, saying: "I'm actually feeling good. I had a really strong finish last year.

"The last couple of months, I took a bit [of time] coming back from an injury, so it took a bit to kind of get rolling, but I'm entering with confidence, getting my ranking back up slowly and had a really good preparation. [I am] training really hard, eating well and I feel like I'm ready to go."

The 32-year-old has been drawn against countryman Felix Auger Aliassime in the first round and appreciates the task at hand against the number six seed, who won three of his four ATP titles in 2022 in October before winning the Davis Cup alongside Pospisil in November.

"I would say arguably he was the most in-form player at the end of last year," Pospisil said. "Four or five tournaments in a row and beat the top players in the world. So obviously, extremely talented young player, very physical.

"I know his game quite well. I mean, I've known him for many years. He's a fellow Canadian and Davis Cup team-mate.

"I have a lot of confidence in my abilities, so I feel like if I'm playing well, then I can beat anybody on any given day. It's going to be a tough ask just because he's playing so well these days."

Welcome to the weird world of pandemic era men's tennis, where the world number five is unmistakably the man to beat.

Novak Djokovic sits head and shoulders above the rest for now, and those ranked higher would surely recognise that too, as the Australian Open arrives.

The 35-year-old Djokovic is playing the tennis of a 25-year-old, and being allowed his liberty after arriving in Australia is good news for him, auspicious for the rest of the Melbourne Park field.

Djokovic was being packed off on a flight out of the country around this time last year, after a saga that made minor international celebrities out of local journalists who could interpret the ins and outs of court proceedings.

He remains unvaccinated against COVID-19 as far as is known, but Australia has relaxed its border controls and rolled out the red carpet for Djokovic this time, rather than arrange for him to be detained.

Had he been allowed to play in Australia and North America last season, Djokovic would surely have remained on the top rung of the rankings ladder.

Over the coming fortnight, Djokovic will chase down a 10th Australian Open title and a record-equalling 22nd men's singles major.

What might stop him reaching those goals? Stats Perform has looked at areas where there might be a crumb of hope for his rivals.

Frosty reception?

There might be the odd jeer. He has never been universally popular and he has, through his vaccination choices, seemingly given those that disliked him anyway another stick to beat him with.

But look, if you think crowd pressure is going to get to Novak Djokovic, you haven't watched enough Novak Djokovic. Move on.

Besides, his 'Nole' army is sure to mobilise in Melbourne. He won't be found wanting for support.

Weight of expectation

The greats in sport rarely get flustered, but perhaps these are the moments, as history approaches, when even a model of focus such as Djokovic might miss a step.

You can look at the 2021 US Open final, when Djokovic was chasing a rare Grand Slam of all four majors in the calendar year, only to lose in straight sets to Daniil Medvedev in the Flushing Meadows final.

He would have gone to 21 slams with that win, too, edging ahead of Rafael Nadal and Roger Federer with whom he was locked on 20 majors. Instead he was flat, out of gas. The greats do have bad days, but they're rare.

Nadal got the jump on both Djokovic and Federer by winning the Australian and French titles last year to unexpectedly surge to 22 slams, before Djokovic took Wimbledon to narrow the gap and Federer retired to make it a two-man race.

Djokovic has won four of his five finals since Wimbledon, with the exception being a surprising loss to Holger Rune at the Paris Masters.

If he loses, it might have to be early, while still relatively cold. Djokovic has a 100 per cent strike rate once he reaches the semi-finals in Melbourne, never failing to take the title once he reaches the final four.

The #NextGen stars

Who are we looking at here, now we know Carlos Alcaraz is going to be absent? The world number one's hamstring blow has only boosted Djokovic's title chances, while removing the tantalising prospect of a first grand slam match-up between the pair. To date, they have only played once, with Alcaraz winning a tight contest on clay in Madrid last season.

In fact, who even is #NextGen? Stefanos Tsitsipas has been around forever, it feels, but is just 24, the same age as Casper Ruud, who is very much on the rise after two slam finals last season. World number three Ruud is just about #NextGen, but fourth-ranked Tsitsipas probably isn't. His slam results have tailed off, and it would be a significant surprise if the Greek made it to the final from the top half of the draw. He has done well in Australia over the years though, with semi-final runs in three of the last four seasons.

Norwegian Ruud is a potential semi-final opponent for Djokovic, and that could deliver drama. Felix Auger-Aliassime is on the other side of the draw and won four titles last year, yet all were relative tiddlers, while it might be too soon for Rune to win over five sets against an all-time great, but he is a possible quarter-final foe for Djokovic.

So is a certain other player, who long left behind the #NextGen ranks...

Nicholas Hilmy Kyrgios

Nick Kyrgios versus Rune in the third round is a lip-smacking prospect. And if that happens and Kyrgios comes through it, despite having not played on tour yet this year, the prospect of a quarter-final against Djokovic would likely loom large.

Tennis being tennis, strange things can happen, but given his kind draw it is hard to see anyone beating Djokovic before the quarter-final stage. Should it be Kyrgios waiting for him at that point, it will be popcorn at the ready.

Last year's Wimbledon final was decided by a fourth-set tie-break, rather than what would have been a dishy fifth set, and Djokovic would again fancy getting the better ot the bellicose but hyper-talented Australian.

Yet Kyrgios has beaten Djokovic twice in their three career meetings, so this is potentially the real landmine on the path to the final. If someone can defuse Kyrgios in the early rounds, Djokovic would have no complaints whatsoever.

Djokovic's own body might fail him

Djokovic abandoned a practice session in Melbourne out of caution over a hamstring issue, but by Friday he was fit enough to face Kyrgios in an exhibition on Rod Laver Arena.

Had he held any serious fitness worries, he surely would have given that a swerve. Showing up sent a message to the field.

This is not to say Djokovic's health will hold and his body will last the distance, but then the same is true of everyone in the draw. This is tennis at the highest level and Djokovic has fought his way to grand slam titles while carrying injury worries in the past, and you suspect he will again, probably as soon as Sunday, January 29.

The Professional Tennis Players Association is committed to equal pay for men and women at grand slam level, according to the man who teamed up with Novak Djokovic to launch the organisation.

Vasek Pospisil, whose on-court doubles efforts helped Canada win the Davis Cup for the first time in November, said the PTPA would "fight for both sides" in its efforts to improve players' prospects throughout the sport.

The breakaway union has caused controversy, with the ATP and WTA, which run the men's and women's tours, adamant they already have significant player representation when it comes to making decisions in the best interests of tennis.

Djokovic quit as president of the ATP player council to become the figurehead of the PTPA, which was launched at the height of the pandemic during the 2020 US Open.

There was initial criticism of the PTPA when no women appeared to be involved.

However, Pospisil said at the time discussions were ongoing, and ahead of the upcoming Australian Open, its first executive committee was unveiled, consisting of four men and four women.

Joining Djokovic and Pospisil are Hubert Hurkacz and John Isner, plus WTA players Paula Badosa, Ons Jabeur, Bethanie Mattek-Sands and Zheng Saisai.

Pay has been equal at all the grand slams since 2007, when Wimbledon announced it would reward women the same amount it pays men.

Asked about equal pay at the four majors and the PTPA's position, Pospisil told Stats Perform: "From day one, we always knew that this would only be successful with the women, and that has always been our goal. And so we're really happy that we're gaining a lot of traction now on the women's side.

"Currently, there is equal pay at the grand slam level, I believe, so that's obviously amazing.

"It is a joint organisation, both men and women, and we'll do everything to fight for both sides.

"Obviously, they're separate tours. The WTA, ATP, and grand slams are joined, of course. So, the staff will have their hands full with trying to advocate for both sides.

"It's a unified player association for both men and women, and we're really proud of that and where we're going."

Those already involved, and those the PTPA will hope to attract, are being advised the union is aiming to bolster the rights – and at the bottom line, the earning potential – of all involved.

There is currently significantly more money on offer on the ATP tour than on the WTA circuit, which points to issues of inequality remaining in the sport.

It has been known in recent times for some high-profile tournaments, where tours converge, to pay its men's champion more than its title-winning woman. This is despite events on both tours being best-of-three-set matches, whereas in the slams women play best-of-three and men play best-of-five, a matter that has long been a trigger for equal-pay debate.

Pospisil believes the WTA has a "smart and passionate" group of eight on its ExCo and said the "energy was amazing" when the group met for dinner on Thursday in Melbourne.

"I just have such a good feeling after a few years of working on this," Pospisil said. "To finally be at the stage where we're ready to go, are launching, got everything we need, and we have amazing player board reps that honestly we couldn't be happier with."

Djokovic, a 21-time singles grand slam winner, is at the forefront, and Pospisil said the 35-year-old Serbian's role has been crucial.

"I feel like you need somebody that is at the top of the sport," Pospisil said. "So, I just think all the players and our organisation, we're very lucky that he's so supportive and that he's stuck his neck out and is fighting for what he believes in and what he believes is right."

Nick Kyrgios insists he is serious about being ready to quit tennis the minute he wins a singles grand slam title.

The Australian went close last year to ending his long wait, only to lose in four sets against Novak Djokovic in the Wimbledon final.

Now aged 27, Kyrgios wants to achieve glory at a major to satisfy that urge, before stepping off the court for good. If it comes at the Australian Open over the coming fortnight, it will be all the better for him.

Asked whether he stood by his previous comments, Kyrgios said: "A hundred per cent. It's a lot of training, a lot of work, and I just want to be able to eat whatever I want, drink what I want to drink and just relax.

"It's a hard lifestyle, the dedication these guys show day in day out. I did a bit of that last year, had a great year to show the world I'm still one of the best.

"I'm going to try to do it this year, and hopefully I can do it, but it'll be hard."

Kyrgios is ranked 21st by the ATP, but that can be considered a false position, given he collected no points for his career-best Wimbledon run. The tours stripped the London slam of ranking points due to its banning of players from Russia and Belarus.

The 1,200 points Kyrgios would ordinarily have taken away from the All England Club would have nudged him towards a top-10 placing.

There is the tantalising prospect of Kyrgios facing nine-time Melbourne Park champion Novak Djokovic in the Australian Open quarter-finals this year, and they went through a light-hearted dress rehearsal on Rod Laver Arena on Friday.

Speaking after that exhibition match, Djokovic said Kyrgios' two wins from their previous three tour-level encounters meant the sky was the limit for the man from Canberra.

"He is 2-1 against me, so as far as I'm concerned he can win anything," said Djokovic.

According to Djokovic, Kyrgios had been unaware of the potential for a meeting between the pair in the Australian Open last eight.

Serbian Djokovic has done his homework though, and appears to have mapped out his potential route to what would be a record-equalling 22nd men's singles grand slam title.

"I have to be honest, I think most of the guys are studying the draw pretty seriously, but you have to take it one match at a time," Djokovic said, speaking on Channel Nine.

"We think every player has so much motivation and inspiration to be able to play his best in the court, to perform well, so you cannot underestimate anybody, you cannot take any match for granted.

"It's a hopefully long two weeks. I know Nick and I are in the same part of the draw – he didn't know that by the way. Before the match I told him."

Novak Djokovic returned to action in front of a packed Rod Laver Arena crowd for the first time in two years, and declared: "It's great to be back."

The nine-time Australian Open champion was denied a role in last year's tournament when his vaccination status, having refused a COVID-19 jab, led to him being detained in a Melbourne immigration centre and later deported.

He was briefly released in January 2022 to practise at Melbourne Park before the tournament began, only to be effectively thrown out of the country days later.

With Australia's border controls having since been relaxed, and vaccination status no longer a condition of entry, Djokovic has had the red carpet rolled out this year, befitting his status as the most successful male singles player in the Australian Open's history.

He faced Nick Kyrgios in an exhibition match on Friday evening in Melbourne, with the stadium court sold out and the match screened on national television.

Kyrgios won 4-3 2-4 10-9, in what was a largely light-hearted encounter, a jumped-up practice session. It inevitably lacked the intensity of their last meeting, when Djokovic prevailed in four sets in the 2022 Wimbledon final.

A fierce backhand from Kyrgios in the match tie-break briefly caught out Djokovic, who was wrong-footed and volleyed out of court before slumping to the floor as though shot.

There was more than a little dramatic licence about his fall, and about the match in general, typified by the pair being joined on court by wheelchair players and a pair of leading juniors for the decisive tie-break.

The result did not matter, though it will if these two meet in the quarter-finals of the year's opening grand slam, as they might after the draw was revealed on Thursday.

Djokovic, who did not appear hampered by a recent hamstring niggle, told the crowd: "It just feels great to be back in Australia, back in Melbourne.

"This is the court and the stadium where I created the best memories of my tennis career. Back in 2008 it was the first time I won a grand slam here, and 15 years later I'm here again, and I'm competing at a high level, so I must be grateful for this opportunity to be here.

"Thank you guys for welcoming me in a good way tonight, I appreciate it."

It was a night for jollity and camaraderie, but should both reach that quarter-final date, Djokovic said: "I don't think we'll be this friendly to each other."

Kyrgios, who defended Djokovic during last year's January crisis, said of the 35-year-old Serbian: "It's so important to have him around.

"One of the greatest already left us last year, Roger [Federer], and I don't think we actually knew how special the guys are to our sport, so every time Novak's around at these events I want to beat him, even though I can't at a grand slam."

The Australian Open begins on Monday, when Djokovic facing Spain's Roberto Carballes Baena first. Djokovic is chasing a 22nd grand slam title, which would equal the men's singles record held by Rafael Nadal.

Kyrgios, yet to win a singles slam, starts against Russian Roman Safiullin.

Nick Kyrgios believes only "a clown" would give Novak Djokovic a hard time at the Australian Open as the Serbian chases a major slice of tennis history.

It was Kyrgios who prominently came to Djokovic's defence when the nine-time champion at Melbourne Park was detained in an immigration facility and then deported ahead of last year's Australian Open due to his COVID-19 vaccination status.

The previously testy relationship between the pair has become increasingly friendly, to the point they will meet in a practice match at Rod Laver Arena on Friday, ahead of the season's first grand slam. That match sold out in a flash, reflecting the popularity of both men.

Kyrgios described their growing closeness as a "bromance" at Wimbledon last year, although Djokovic laughed off that label.

Djokovic, who has refused to be vaccinated against the coronavirus, will have many on his side over the coming fortnight as he chases a 10th grand slam in Australia and a 22nd overall, which would match Rafael Nadal's men's singles record.

Tournament director Craig Tiley has said anyone that boos Djokovic would risk being thrown out, while Kyrgios called for "respect" to be shown to the 35-year-old superstar.

Kyrgios described Djokovic as "the best that we've got", adding: "I would say, Novak's here and he hasn't made any rules. He's abided by them for the last two years or whatever.

"He's here and all he wants to do is put on a show. He's chasing things that athletes rarely are able to chase. He's one of the greatest athletes of all time, not just in the tennis court.

"I think as fans we should be appreciating that. I know there's going to be fans who are not wanting him to win, but I think they can't cross that line as fans.

"You guys have paid money to watch a guy play, it's a bit contradictory if you're going to go there and be a clown about it.

"You've got to respect him a little bit at the end of the day because he's one of the best who's ever done it."

Kyrgios has a 2-1 record against Djokovic, though both of his wins came back in 2017 and Djokovic won in four sets in their last meeting: the 2022 Wimbledon final.

Should they both win through the early rounds in the season's first grand slam, the draw is such that they could go head to head again in the quarter-finals.

Already, Kyrgios is talking about possibly abandoning doubles duty with Thanasi Kokkinakis in order to focus on singles.

He and Kokkinakis took the doubles title last year, but Kyrgios said on Thursday: "We're singles players at heart and the doubles grand slam last year was a flash in the pan.

"We haven't had one conversation about doubles yet. If we play, we play; if we don't, we don't."

Nine-time champion Novak Djokovic will make his return to the Australian Open against Spain's world number 75 Roberto Carballes Baena.

After being deported from Australia last year amid a row over his refusal of a COVID-19 vaccination, Djokovic is firmly back in favour and chasing history in Melbourne, with a record-equalling 22nd men's singles grand slam in his sights.

He begins against an opponent who in four previous main draw appearances has only ever won one singles match at Melbourne Park.

Defending champion Rafael Nadal, whose 22 slam titles Djokovic is seeking to match, has a tricky opener against rising British star Jack Draper, the world number 40.

Second seed Casper Ruud will tackle Czech Tomas Machac first up, with the 115th-ranked player unlikely to prove too daunting an obstacle for last season's French Open and US Open runner-up.

Fifth seed Andrey Rublev could face an awkward assignment against wildcard and former US Open winner Dominic Thiem, while Australia's Nick Kyrgios begins against Russian Roman Safiullin.

Neither 13th seed Matteo Berrettini nor five-time runner-up Andy Murray would have been delighted to be paired together, but that is what happened in Thursday's draw.

In the women's singles, top seed Iga Swiatek starts her bid for a first Australian Open title against Germany's Jule Niemeier, who caught the eye last year on a run to the Wimbledon quarter-finals.

American seventh seed Coco Gauff starts against Czech Katerina Siniakova, while Jessica Pegula, Gauff's third-seeded compatriot who recently beat Swiatek in the United Cup, will face Belgian Jaqueline Cristian.

Gauff could face former US Open winner Emma Raducanu in the second round. Unseeded Briton Raducanu starts against Germany's Tamara Korpatsch.

Former champions Sofia Kenin and Victoria Azarenka go head to head in the first round, with American Kenin unseeded this year and Belarusian Azarenka the 24th seed.

Azarenka's compatriot Aryna Sabalenka is fancied to do well, having banished last year's serving yips, and the fifth seed starts against Czech Tereza Martincova.

Tunisian second seed Ons Jabeur, runner-up at Wimbledon and the US Open, begins her latest quest for an elusive grand slam title against Slovenian world number 88 Tamara Zidansek.

Former US Open winner Bianca Andreescu is unseeded in Australia and Czech 25th seed Marie Bouzkova drew a possible short straw by getting the Canadian in round one.

Novak Djokovic cut short a practice match against Daniil Medvedev on Wednesday as a hamstring injury lingers ahead of the Australian Open.

Record nine-time Melbourne champion Djokovic is back in Australia after he was denied entry last year and subsequently deported due to his COVID-19 vaccination status.

The 21-time major winner is expected to be a contender again at the first grand slam of the 2023 season, but his preparations were hampered by an injury scare on Wednesday.

Djokovic, who won his first title of the year in Adelaide last week, was able to complete only a single set of an exhibition against Medvedev.

"It's a hamstring that I had problems with in Adelaide actually last week," he explained to Nine's Wide World of Sports. "It was against Medvedev, when I played the semi-final, and I played with him today in a practice match.

"I just felt it a bit, pulling, and I didn't want to risk anything worse. I played a set, apologised to him, and he was understanding.

"I just want to avoid any bigger scares before the Australian Open."

Having required a lengthy medical timeout against Medvedev in Adelaide, Djokovic had described the issue as "nothing too serious".

The Serbian is also scheduled to play a practice match against home hopeful Nick Kyrgios this week.

Novak Djokovic will face Nick Kyrgios in a practice match ahead of the Australian Open.

Djokovic marked his return to Australia by beating Sebastian Korda to win his 92nd Tour-level title on Sunday in Adelaide.

Kyrgios, meanwhile, did not feature in the inaugural United Cup for Australia after withdrawing due to injury.

They will now meet in a practice match at Rod Laver Arena on Friday, ahead of the season's first grand slam.

Ticket proceeds will go to the Australian Tennis Foundation.

The duo have had a turbulent relationship in the past, though last year appeared to be on better terms.

Kyrgios came to Djokovic's defence when the Serbian was denied entry to Australia and subsequently deported ahead of the 2022 Australian Open due to his COVID-19 vaccination status.

Australia's policy on non-vaccinated individuals entering the country has now changed, and Djokovic had his three-year suspension from the nation revoked, allowing him to compete in Melbourne this year.

Krygios has a 2-1 record against Djokovic, though both of his wins came back in 2017.

They last met in the final of Wimbledon last year, with Djokovic coming out on top 4-6 6-3 6-4 7-6 (7-3).

Novak Djokovic battled back from match point down to win his first tournament of the year with a thrilling victory over Sebastian Korda in the final of the Adelaide International 1.

The 35-year-old certainly did not have it all his own way as the American gave a brilliant account of himself, but Djokovic had the nous to get his 92nd tournament win over the line 6-7 (8-10) 7-6 (7-3) 6-4.

During a gruelling encounter that lasted three hours and 11 minutes, there was precious little to separate them with only three breaks of serve in total.

Two of those came in the first set. Korda had the initial advantage, a gorgeous backhand down the line punishing a stranded Djokovic, but he instantly hit back as his opponent found the net with what looked a routine shot.

The subsequent tie-break was similarly neck-and-neck until a Djokovic slice went long and then he put another return into the net to hand Korda the set, the Serbian venting his frustration at his team at the interval.

Korda then had the opportunity to win the championship towards the end of the second set, but Djokovic worked the situation bravely before a smashed volley emphatically saved him, with another tie-break soon arriving.

Djokovic surged into a 6-1 lead and eventually grasped his third set point, and from then on there only looked like being one winner, with the 21-time grand slam champion pouncing on his first break point in the decider to take the win.

This tournament was of course Djokovic's first in Australia since being deported ahead of the 2022 Australian Open due to his unvaccinated status.

Upon his return to the country where he has won nine grand slams, Djokovic was feeling the love.

"It's been an amazing week and [the fans] made it even more special. For me to be standing here is a gift, definitely," Djokovic said in the trophy ceremony.

"I gave it all today and throughout the week in order to be able to get my hands on the trophy.

"The support that I've been getting in the past 10 days is something that I don't think I've experienced too many times in my life, so thank you so much [to] everyone for coming out every single match."

Success ensured Djokovic levelled Rafael Nadal (92) for fourth-most men's singles titles in the Open Era, with only Ivan Lendl (94), Roger Federer (103) and Jimmy Connors (109) winning more.
