Ons Jabeur became the latest big-name casualty at the Australian Open when she suffered a second-round defeat to Marketa Vondrousova.

Jabeur has been hampered by knee and back injuries at the start of the season and the second seed suffered more pain on Rod Laver Arena, where the excellent Vondrousova sealed a 6-1 5-7 6-1 win in the early hours of Friday morning in Melbourne.

Vondrousova has been troubled by multiple wrist injuries since she was a runner-up at the French Open in 2019, but appears to have put those issues behind her.

The Czech left-hander dominated the first and final sets after Jabeur showed her fighting spirit in the second to force a decider at Melbourne Park.

A runner-up at Wimbledon and the US Open last year, tenacious Tunisian Jabeur appeared to be in some pain and struggling for breath during a match in which she made 50 unforced errors.

The world number two struck 27 winners to her opponent's 17, but followed the likes of Rafael Nadal, Casper Ruud and Emma Raducanu in making early exits when she overcooked a forehand.

Vondrousova, ranked 78th after an injury-hit 2022 season in which missed three of the four grand slams, will face compatriot Linda Fruhvirtova in round three.

Aryna Sabalenka was stuck in the biggest crisis of her tennis career 12 months ago, but the Belarusian big-hitter has found light at the end of a dark tunnel.

In a second-round win over Wang Xinyu at the 2022 Australian Open, Sabalenka served 19 double faults, and it was remarkable that she still pulled off the victory.

But it was no blip. In four matches, stretching from the 2021 WTA Finals to two tournaments in Adelaide at the beginning of the 2022 season, Sabalenka served a total of 74 double faults.

She considered it a success in round three at the Australian Open when she served 10 double faults against Marketa Vondrousova, such was the extent of her problem.

"I think it's more mental," Sabalenka said at the time, "because I put a lot of pressure on myself about my serve, and the last matches I was trying to control everything on my serve; my legs, my arm, the ball toss. And it was overthinking."

A year on, and Sabalenka is looking a different player, one that perhaps might finally be ready to win a singles grand slam.

That breakthrough might come this fortnight, with Sabalenka in scintillating form on Thursday as she beat Shelby Rogers 6-3 6-1 on Rod Laver Arena.

And here's the thing: she served three aces and not one double fault.

The yips have been cured.

"I worked a lot on my serve," said the 24-year-old after the Rogers match. "Like, really a lot. You can't even imagine how much I worked. I'm just super happy right now that everything is working.

"Oh, my God, I did almost everything to try to fix my serve. The whole year we were trying different things mentally, mental stuff, technique, technical, trying to breathe differently.

"I tried a lot. I watched a lot of different videos, from when I had no problems, when I had problems, trying to understand what is different."

Sabalenka had three double faults in her first-round win over Tereza Martincova, but three is fine, normal even. Zero in round two is something special.

The fifth seed will tackle Belgium's Elise Mertens on Saturday for a place in the last 16, knowing she managed to make it through to round four last year with a malfunctioning game.

The sky is the limit for Sabalenka if the serve is reliable. A three-time slam semi-finalist, her all-round numbers against Rogers were good, with 32 winners against 18 unforced errors a healthy ratio.

She reached the title match at the WTA Finals in November, a big moment at the end of a challenging year. Now a bigger goal is in her sights.

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.

Emma Raducanu hopes to face Coco Gauff again with a little more practice under her belt.

Raducanu lost 6-3 7-6 (7-4) to the 18-year-old American on Wednesday, as her Australian Open hopes were dashed.

The 2021 US Open champion failed to take two set points to restore parity at Rod Laver Arena, and ultimately paid the price when Gauff won the tie-break.

Raducanu suffered an ankle injury while in action at the Auckland Open earlier in January, and battled through the pain barrier to play in Melbourne.

"What I had to [do] to be in the draw is a massive effort and achievement," Raducanu said.

"I would say all the chips were against us, and the chances of me playing this tournament were very, very low.

"So I had extremely limited practice time, I think I can say that now I'm not competing anymore.

"It was obviously going to be a push to get me on the court. I think 13 days ago if you would have said 'Hey, you're going to be in the draw and win a round', it would have been a massive effort for sure.

"Saying that, I still think I didn't necessarily play my best [against Gauff]. Although the second set I had chances, I felt like I could have done better myself. But props to her. She's a great, great opponent and great athlete."

It was the first meeting between Raducanu and Gauff, who is ranked 70 places higher than the 20-year-old by the WTA.

Raducanu has slipped down to 77 in the world rankings but is confident she will give Gauff a sterner test the next time they go head-to-head.

"I'd really like to play her again. Maybe with more than five hours of practice under my belt," Raducanu said.

"Yes, she's a great opponent. I think that we're going to be playing each other many times in the future as we're both young and coming. We're going to be the next generation."

Raducanu is now looking forward to building up her fitness and form over the first half of the season.

"I'm just looking forward to putting in the work, and I feel I'm putting in a good system in place," she added.

"I'm feeling good and confident that in six months' time I know it's not going to be the finished product, but hopefully I would have made strides."

Coco Gauff may not be the most popular person on her own TikTok, but she impressed the crowds at Melbourne Park as she beat Emma Raducanu in straight sets.

In what was a much-anticipated clash at the Australian Open between the world number seven and the 2021 US Open champion, it was Gauff who emerged on top with a 6-3 7-6 (7-4) victory to seal passage to the third round.

It also made Gauff the first woman to win 100 Tour-level main draw matches before turning 19 since Caroline Wozniacki did so in 2009.

The 18-year-old took the opening set by stepping up her game on key points, breaking her British opponent twice while saving six of seven break points against her.

In an even second set, Gauff was forced to save two set points as Raducanu tried to take advantage of the American's struggling forehand.

However, Gauff hit back to force a tie-break that she won in style with a drop shot followed by a lob.

"I just told myself to hang in there and I was playing really good tennis," Gauff said in an on-court interview. "I think we both started off rocky but I think the match was good quality for the most part.

"Considering the circumstances I think both of us were nervous, this was a long-anticipated match basically since the draw came out so I'm glad that it was a good match for you guys.

"At a grand slam you have to win seven matches and you have to expect to play the best, obviously you hope it's not in the second round but what can you do?

"I feel like we handled the pressure really well and kudos to Emma, I know she had a tough week in Auckland [suffering an ankle injury] so good for her to be able to play at this level after such a scary moment."

Gauff also joked about a TikTok she recently posted that divided opinion on her parents' dancing ability.

"I posted a video online and it got like a million views and everyone was hating on my dad in the comments, so I kind of felt bad... parents really do anything for their kids so I'm glad my dad took one for the team."

Asked who is the best dancer of the three of them, she replied: "Probably my mom, at least that's what the comments said.

"They said my mom ate both of us up... a lot of people asked for a solo video just of her and I was like: 'No, I'm the star, how do I get outshined on my own TikTok?'"

Jessica Pegula has been wearing a number three on her outfit at the Australian Open, and she confirmed it is to show support to Damar Hamlin.

Buffalo Bills safety Hamlin went into cardiac arrest during the game against the Cincinnati Bengals on January 2 and spent over a week in hospital, much of that time in critical condition.

Pegula's parents own the NFL franchise as well as the Buffalo Sabres NHL team, and during her second-round win over Aliaksandra Sasnovich in Melbourne, was seen with a number three on her skirt, which is Hamlin's number and became a symbol of appreciation from well-wishers during his recovery.

"I definitely wanted to do something," Pegula said after her 6-2 7-6 (7-5) victory over Sasnovich. "We were kind of figuring out what the Bills and the Sabres were doing, just as far as what was the message.

"I knew they would probably do something and what message were they trying to send. It ended up being [that] the three was the symbol.

“I just thought it would be cool to put on my outfit here. I thought it would be a fun way to kind of connect with the team and then also just show my support."

There had been speculation that the number was related to her ranking, with the 28-year-old coincidentally the WTA world number three heading into the Australian Open, where she is the third seed, but Pegula laughed off the suggestion.

"I saw someone tweet that: 'Why would you put your ranking on your skirt?'. I'm, like, 'No, that’s not why,'" she said with amusement.

Pegula will play the winner of Olivia Gadecki and Marta Kostyuk in round three at Melbourne Park.

World number one and tournament favourite Iga Swiatek feels second-round opponent Camila Osorio did not do much wrong despite going down 6-2 6-3 on Wednesday.

Swiatek is seeking her fourth career grand slam singles title, and the 21-year-old is yet to drop a set through two rounds at the Australian Open.

She was nearly flawless in her service game against Osorio, landing 80 per cent of her first serves fair while also committing zero double faults, and she was just as impressive when on the return.

Osorio was able to win just 31 per cent of her service points in the opening set (eight-of-26), and for the match she only held serve on two occasions from eight attempts.

Despite Swiatek's clear advantage in both phases, Osorio managed to break her serve three times, and the Polish superstar said she was made to earn every point.

"It was much tougher than this score says – it was really intense physically and Camila was really running to every ball," she said. "She didn’t give up. She didn’t give me many points for free. 

"So I needed to really work for each of them and it was tough, but I’m happy that I was proactive and trying to just play a little bit to put pressure [on her]. I’m pretty happy that I won and I can play next round."

Swiatek also shared a story about when the rain started pouring on Tuesday night in the midst of her walk, urging spectators in jest to come to her aid if a similar situation arises in the future.

"In Melbourne it’s usually sunny, except today and yesterday," she said. "So I need to change my plans. 

"Yesterday I actually went for a walk at 7[pm] and it started raining, and I was just hiding under the tree, waiting for like 30 minutes.

"So if there’s anybody who’s going to see me tonight walking in the rain, please save me, give me an umbrella or something."

Swiatek's march to what would be her first Australian Open final continues when she takes on the winner between Cristina Bucsa and Bianca Andreescu in the third round.

World number one Iga Swiatek had no problem dealing with Camila Osorio during Wednesday's second round, advancing with a 6-2 6-3 victory.

Swiatek, 21, is seeking her fourth grand slam title and her first at the Australian Open, having already won the French Open twice before claiming her first US Open crown this past season.

Against Osorio, it was Swiatek's ability to consistently return that was the difference, holding the Colombian to just a 31 per cent success rate on her service points in the opening set (eight-of-26).

It resulted in a lightning-quick start for the Polish superstar, winning the first four games of the match, and despite giving back a couple breaks of serve, Swiatek did not allow Osorio to hold serve a single time in the opening frame.

Osorio was able to finally hold serve to begin the second set, before Swiatek again rattled off four consecutive games to collect a double-break and a winning lead.

In a remarkably clean performance from the tournament favourite, Swiatek landed 80 per cent of her first serves fair while committing no double faults, and both players finished with more winners than unforced errors.

With the victory, Swiatek will now face the winner between Cristina Bucsa and Bianca Andreescu in the third round.

Data Slam: Swiatek in legendary company

Swiatek has now won 53 of her first 65 grand slam matches – the sixth-best total through 65 attempts in the Open Era.

She trails only Margaret Court (61), Monica Seles (60), Chris Evert (57), Martina Hingis (56), Billie Jean King (56) and Tracy Austin (54).

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.
