Naomi Osaka said she was "really nervous" before facing Anastasia Pavlyuchenkova but showed no signs of that as she breezed into the second round of the Australian Open.

Osaka looked dominant on day one of the first grand slam of the year as she welcomed being able to play in front of a crowd at Melbourne Park, taking only 68 minutes to wrap up a 6-1 6-2 victory.

The US Open champion has beaten Pavlyuchenkova three times in a row after losing when they first met in 2017 but was wary of facing the Russian on Rod Laver Arena.

Third seed Osaka said: "I was really nervous coming into this match. I know that I've played her before, and it was really tough. I just wanted to play well.

"The most recent memory I have of playing her was in the Osaka final [that Osaka won 6-2 6-3 in 2019], so it's always really hard to play someone that good in the first round.

"For me, I feel like it might have also helped in a way because I calmed my nerves because I felt like I couldn't afford to be that nervous. But, yeah, it was a tough match."

Serena Williams and Simona Halep stormed into round two, but the 2016 champion Angelique Kerber crashed out with a 6-0 6-4 defeat to world number 63 Bernarda Pera.

Alison Riske and Wang Qiang were the only other seeds to fall, losing to teenager Anastasia Potapova and qualifier Sara Errani respectively, while Bianca Andreescu made a winning comeback.

Williams sisters among major winners to make serene progress

Serena Williams did not look at all troubled by a shoulder problem as she started her latest quest to win a record-equalling 24th major singles title with a 6-1 6-1 demolition of Laura Siegemund.

Her older sister, Venus, also advanced in straight sets, beating Kirsten Flipkens 7-5 6-2.

Iga Swiatek, the French Open champion, was too good for Arantxa Rus, winning 6-1 6-3, and Petra Kvitova got past Greet Minnen 6-3 6-4.

Kerber will not be claiming a fourth major crown this month after falling to Croatia-born American Pera.

Halep planning to oust another Australian

Two-time major winner Halep was a cut above Lizette Cabrera, winning 6-2 6-1 in 59 minutes, and is looking forward to facing another Australia in the second round in the form of Ajla Tomljanovic. 

"I like to be here, so I like to play Australians," Halep quipped.

"I feel good. My body is fit. It's always difficult to play a big hitter. So, I have to be strong on my legs, focus on myself and give my best.

"I expected a tough match because I played against her before and I know how it's gonna be. She's a good opponent, a good player, and I will focus just on myself like I do every time, but I'm ready for a good battle."

Andreescu back in business

Andreescu put her injury woes behind her, battling past Mihaela Buzarnescu 6-2 4-6 6-3 in her first match for 15 months.

The Canadian had not played in a grand slam since winning the US Open in 2019 but was back in business on John Cain Arena.

Eighth seed Andreescu said: "After the match, I sat down with my team a little bit, and I'm like, 'Oh, guys, here we go again, those three-setters' and they just started laughing because they obviously knew what they were getting themselves into.

"But those matches are super good for me in my opinion because it really shows that I can scramble when I really need to, or if there's some pressure I can dig my way through it somehow. When my back is against the wall, not only today, but I've noticed throughout my last couple tournaments in 2019, I've been able to pull through with those."

Serena Williams will win a 24th grand slam singles title despite the mental pressure of trying to match the record having held her back, Ana Ivanovic says.

American Williams breezed into the second round of the Australian Open on Monday with a 6-1 6-1 victory over Laura Siegemund.

She won her 23rd major singles title in Melbourne in 2017, taking her to within one of matching the all-time record held by Margaret Court.

However, she has failed to win any of the following 14 slams, marking the longest span in her professional career without lifting any of the four biggest trophies.

Williams has won 22 of her majors over the last two decades, at least 15 more than any other women's player in that time, but her most recent four slam finals have ended in defeat.

Ivanovic, the former world number one who reached the final in Melbourne in 2008, wonders if the significance of matching Court's tally may have added extra pressure on Williams.

However, she remains convinced the 39-year-old will claim another title, telling Stats Perform News: "Yeah, definitely after winning so many grand slams, you still have it and especially [as] she reached so many finals, even though she didn't win a title.

"So, I think it's just a matter of, she proved that she can win matches and she can get a part in the grand slams.

"I think she wants to go further for the record. So I think that's maybe a bigger issue than just winning a title. So, it's both a little bit, I guess mental as well. But I'm sure she can do that. And I'm sure that's why she's there and still pushing and still being on top of the game after so many years."

"She's definitely an icon and a very, very powerful player. And I remember you know, when I played against her, she's very intimidating because her serve is just very, very strong. Her shots are very strong. So you feel like you have to attack and move forward otherwise you don't really have a chance. It was very inspiring to play against her and to play against someone who reached so much in women's sport. I think she will go [down] in history. Definitely."

Reigning champion Sofia Kenin begins her Australian Open defence against home hope Maddison Inglis on Tuesday.

The 22-year-old is hoping to become the first women's player to win successive Australian Opens since Victoria Azarenka back in 2013.

Kenin was a finalist at the French Open last year after winning in Melbourne, having failed even to reach the last eight in her first 11 majors, but she was beaten in straight sets by Garbine Muguruza in the quarter-finals of the Yarra Valley Classic warm-up tournament.

"She seemed very, very solid and very consistent lately, so of course she has a big chance but, like I said, it's so difficult to talk because you don't see the players playing, you don't see what kind of form they're on and how the last months have been for them," said Ivanovic.

"And you know, without competition for so long again, it definitely is going to [have an] affect but she can indeed [win]. One Australian Open and then she went on to the French Open final, so she's definitely been very, very consistent and she's going to I think try to go again.

"I think that's why it's very hard to predict who will be the winner of a grand slam, especially on the women's side. But on the other hand, it's nice to see new faces and new players coming up, and it also brings new excitement to the tour."

Ivanovic also tipped French Open champion Iga Swiatek to challenge in the latter stages, adding: "I do like Iga Swiatek and the way she plays. I like her aggressive game. I like the fact that she runs around and hits her forehead, it was kind of the style that I had. So I really hope she can keep up the work that she did last year and continue to do well."

Novak Djokovic began his quest for a ninth Australian Open title with a convincing straight-sets win over Jeremy Chardy.

The reigning champion and world number one looked in ruthless form as he won 6-3 6-1 6-2 in a little over an hour and a half.

Djokovic, who beat Dominic Thiem in a five-set thriller in the 2020 final, was in an authoritative mood as he took the first two sets in just 56 minutes.

Chardy, whose best grand slam result was reaching the quarter-finals in Melbourne in 2013, offered some valiant resistance in game five of the third set before Djokovic eventually claimed the crucial double break.

The 17-time major winner eased through the final two games in front of a jubilant crowd, finishing with back-to-back aces to set up a second-round match with Frances Tiafoe.

"It makes my heart full to see the crowd in a stadium again," said Djokovic, who has reached at least the semi-final stage in seven of his previous nine majors.

"There's an ongoing love affair between me and the Rod Laver Arena. It's definitely one of the most special courts on the tennis tour around the world and my most successful. Every time I step on this court, I relive those memories."

Djokovic's preparations for the tournament were overshadowed by a row over quarantine conditions for players arriving in Australia, the 33-year-old having lobbied Tennis Australia and state authorities to loosen restrictions for 72 players who had to spend two weeks in their hotel rooms.

There was little about his performance on Monday to suggest any distractions from the task at hand, although he bristled a little in the on-court interview when it was put to him he had been "frustrated" in recent weeks.

"I'm just really glad we're free, playing tennis, back in Australia," he then said. "It's a happy place for us, a happy slam."

Data Slam: Djokovic at his clinical best

Djokovic dropped just nine points on serve and hit 41 winners to just 11 unforced errors, sending down nine aces and one double fault.

Such imperious play left Chardy, who had lost all 13 of their previous encounters, with little chance of an upset.

WINNERS/UNFORCED ERRORS
Djokovic – 41/11
Chardy – 20/26

Serena Williams took inspiration from the "unbelievable" Tom Brady as she cruised into the second round of the Australian Open with a "vintage" performance.

Brady made yet more history on Sunday, the most successful player in NFL history winning a seventh Super Bowl as the Tampa Bay Buccaneers beat the Kansas City Chiefs 31-9.

The incredible Brady, 43, showed age is no barrier, throwing three touchdown passes – two of which were scored by his long-time friend Rob Gronkowski – and completing 21 of 29 throws for 201 yards.

Brady did now allow any interceptions as he picked up the MVP award at Raymond James Stadium.

Williams started her quest for a record-equalling 24th grand slam singles title with a 6-1 6-1 defeat of Laura Siegemund on Monday, then paid tribute to her fellow American Brady.

She said of his exploits: "It's unbelievable. I just was watching as much as I could to see. My only word is it's unbelievable. I kept saying: 'This is unbelievable, this is unreal'.

"You can't say it was the system he was at formerly [the New England Patriots]. It's definitely Tom Brady, he's Tom Brady. He's amazing."

Brady banished everyone from his house in the days leading up to the Super Bowl so he could fully focus on inspiring the Buccaneers to victory, but the 39-year-old Williams said she could never do the same as she would not want to be separated from her daughter, Olympia.

"I would not be able to go function without my three-year-old around," Williams said. "I think I would be in a depression.

"We've been together every day of her life, so... Is that healthy? Not at all! Not even close. But every single day I just want to be around her. It's great. Everyone's different.

"I can totally understand why he would banish because if I had the strength to do it, I would too.

"I could see it's definitely a distraction, especially every year that I've played except for the past few months, I finally am starting to get better at it. The first two and a half years was very difficult. I wasn't strong enough to do the banishment."

Williams, who will face Nina Stojanovic in the second round at Melbourne Park, was delighted with the manner in which she swept Siegemund aside and had no issues with her shoulder after withdrawing from a pre-tournament event citing an injury problem.

"This was a good start. Definitely vintage 'Rena'. It's definitely good. I think I'm pretty good at pacing myself in a grand slam," she said.

"I was happy just to get through it. Wasn't sure how my serve would be after a little bit of that shoulder, but it's feeling good, I'm feeling good. So, it felt really good.

"Last year was very crazy for the world, and to be able to do what I love and to be able to come out and compete and play at a grand slam, after the last 12 months, it makes me appreciate the moment even more."

Serena Williams' bid for a record-equalling 24th grand slam title started with a comprehensive win over Laura Siegemund at the Australian Open.

The American star was dominant on her way to a 6-1 6-1 victory over Siegemund on Rod Laver Arena on Monday.

Williams is aiming to join Margaret Court on a record 24 grand slam singles titles and she had no problems against the German in Melbourne.

She improved to 20-0 in the first round of the Australian Open, showing few signs of a shoulder injury she expects to be dealing with throughout the tournament.

Williams lost just 10 games in her previous two wins over Siegemund, but the seven-time Australian Open winner was broken in the opening game.

But Siegemund produced too many errors from then on, Williams winning in just 56 minutes to set up a clash against Nina Stojanovic.

Data Slam: Serena cruises after initial nerves
Williams was broken to 15 in the opening game when Siegemund produced a forehand return winner. However, she steadied, reeling off the next 10 games on her way to a comfortable win.

Williams – 16/15
Siegemund – 4/20

Williams – 4/1
Siegemund – 0/3

Rafael Nadal is "doing everything possible" to play a part in the Australian Open after suffering from back pain for the past two weeks.

The 34-year-old pulled out of Spain's line-up for the ATP Cup earlier this week and was last in competitive action in November's ATP Finals.

Nadal is due to face Laslo Djere in the first round on Tuesday as he seeks a second Australian Open title, but the Spaniard cannot guarantee he will be able to play the match.

"It's not great, obviously," he said. "It's true that for the last 15 days I have been suffering.

"In the beginning, the muscle was just a little bit tired, but I now feel a little bit more stiff than usual.

"The muscle is still tight, so it is difficult to play with freedom of movement."

But Nadal, who has a history of back injuries, is refusing to withdraw from the tournament.

"I have Monday and then playing Tuesday. I don't think about not playing," he said.

"We are doing everything. My physio is here, the doctors [are] here, everybody is helping me in all possible ways. I hope to be ready, that's all. I know sometimes things change quick."

Nadal is not alone in entering the first grand slam of the year below full strength, with the likes of Serena Williams, Sofia Kenin and Naomi Osaka also battling injury problems.

However, the world number two will not use his niggling back issue as an excuse should he suffer an early exit at Melbourne Park.

"I'm not a big fan of finding excuses," he said. "When things happen, you need to find a way to get through."

Nadal can surpass Roger Federer for all-time majors should he triumph at the Australian Open.

He is also looking to become only the second man after Rod Laver to win each major on more than one occasion in the Open era, but his only previous success at the tournament came 12 years ago.

"I think I had the big chance in 2014. I got injured during the match on the back. It was tough," he said.

"I had another good chance in 2012, another good chance in 2017 with a break up in the fifth. I just didn't win the match. 

"That's all, I can't find another reason. It is true that I missed a couple of Australian Opens for injuries, too."

World number four Daniil Medvedev clinched ATP Cup success for Russia, who defeated Italy in Melbourne on Sunday.

On the eve of the Australian Open, Medvedev boosted his preparations by guiding Russia past Italy thanks to a 6-4 6-2 victory over Matteo Berrettini at Melbourne Park.

It was a dominant display from Russia, who won all eight singles matches they played in the ATP Cup, after Andrey Rublev overpowered Fabio Fognini 6-1 6-2 in the second matchup.

"I want to thank my team. Andrey won all of his matches," Medvedev said. "Thank you for being with me here and lifting this trophy in a few moments."

Medvedev heads in Monday's Australian Open in red-hot form, having won a personal-best 14 successive matches, dating back to the start of last year's Paris Masters.

Of those victories, 10 have come against top-10 opponents as 2019 US Open runner-up Medvedev – seeded fourth for the year's first grand slam – prepares to face Vasek Pospisil on Tuesday.

"It's a really big achievement because I also didn't lose a match. Yeah, 10 matches against Top 10 opponents, didn't lose a match in these 10 matches. It's a big boost in confidence," Medvedev said.

"Even when you lose, you know that you're capable of playing this level, and it helps you for the next time to stand up."

While Italy did not taste team success, Jannik Sinner claimed the Great Ocean Road Open on Sunday.

Sinner overcame countryman Stefano Travaglia 7-6 (7-4) 6-4 to earn his second title following the first all-Italian ATP Tour final since 1988.

The 19-year-old Sinner is the youngest player to win two ATP Tour titles since world number one Novak Djokovic (19) in 2006, while he is also the youngest player to celebrate back-to-back trophies since 20-time grand slam champion Rafael Nadal (19) in 2005.

Elsewhere, eighth seed Daniel Evans defeated Canadian sensation Felix Auger-Aliassime 6-2 6-3 to claim his first tour-level title.

Evans became the first Brit to win an ATP Tour title since Kyle Edmund at the New York Open last February.

World number one Novak Djokovic said he does not have "much respect" for outspoken Australian star Nick Kyrgios away from the tennis court.

Kyrgios has been critical of Djokovic in an ongoing feud with the 17-time grand slam champion, who was labelled a "tool" by the former following a list of requests made to Tennis Australia (TA) and the Victorian government for tennis players stuck in hotel quarantine amid the coronavirus pandemic.

Former world number 13 Kyrgios was also critical of Djokovic's decision to stage the Adria Tour in Europe last August – in the midst of the COVID-19 crisis – having previously dubbed the Serb star "cringeworthy".

Djokovic rekindled his rivalry with Kyrgios after being asked about the 25-year-old on the eve of the Australian Open.

"I've said this before," Djokovic told reporters on Sunday. "I think he's good for the sport. Obviously he's someone that is different. He goes about his tennis, he goes about his off court things in his own authentic way. 

"I have respect for him. I have respect for everyone else really because everyone has a right and freedom to choose how they want to express themselves, what they want to do. My respect goes to him for the tennis he's playing. I think he's very talented guy. He's got a big game. He has proven that he has a quality to beat any player really in the world in the past.

"Off the court, I don't have much respect for him, to be honest. That's where I'll close it. I really don't have any further comments for him, his own comments for me or anything else he's trying to do."

Djokovic has won the past two Australian Open finals as he eyes a record-extending ninth Melbourne Park crown.

The 33-year-old, who opens his title defence against Jeremy Chardy on Monday, has won the Australian Open every time he has reached the semi-finals.

Djokovic has reached at least the semi-finals in seven of his last nine grand slam tournaments, winning five of them.

No male has won more Australian Open men's singles titles than Djokovic, who said: "It's a love affair. Probably something similar maybe not like Rafa [Nadal] has with the French Open, but I've been feeling more comfortable on the court each year that I've been coming back. 

"The more you win, obviously the more confidence you have and the more pleasant you feel on the court. It just feels right. If you're in the right state of mind, regardless of the surface, you have a better chance to play at your best.

"When I stepped on the court this year for the first time in the practice session, I relived some of the memories from last year, also the other years that I won the tournament here.

"It just gives me great sensation, great feeling, confidence. It feels right. It feels like the place where I should be and where I have historically always been able to perform my best tennis. Hopefully can be another successful year."

Asked if he still feels nerves, Djokovic – who is looking to close the gap on Rafael Nadal and Roger Federer (both 20) for the most slam trophies – added: "Every match, every match. Every single match. I don't want to speak on behalf of the other athletes, but I just feel like it's almost impossible to eliminate that kind of pressure, anticipation, the nerves coming into any match really for an athlete. At least in my case.

"It's just that I managed over the years to train myself, I think with the experience and with also the dedication that I had off the court to the mental preparation, that helped me react better to those kind of emotions. Sometimes I don't manage to overcome the pressures and the stress and nerves. Sometimes I do. It really just depends. Even though I've been blessed to experience a lot of success, especially here in Australia, but also in my career. I still feel that those failures, if you want to call them that way, even though I don't believe in failures, I just believe in opportunities to improve, kind of the lessons to be learned, but in those matches you lose, big matches, that's where you learn the most.

"That's where you're facing the kind of wall mentally. You're upset. You have a lot of different things happening, and you feel like you let yourself down. That's where it's the biggest opportunity for you to really address that and become stronger, more capable. You can get to know yourself a little bit on deeper levels. It still happens to me.

"Every single tournament, regardless of my previous success, of course I do feel that I have more confidence, more experience, maybe more training in understanding how to deal with these specific situations when I'm coming on the big court, being expected to win 99 per cent of the matches that I play.

"But it's still there. It's still there. I don't think it's ever going to go away. Especially when the occasion is big, when you're playing for the biggest trophies."

World number one Ash Barty ended her Australian Open preparations with a title after defeating Garbine Muguruza in the Yarra Valley Classic final.

Barty – gearing up for the year's first grand slam which gets underway in Melbourne on Monday – defeated sixth seed and 2020 Australian Open runner-up Muguruza 7-6 (7-3) 6-4 on Sunday.

Looking to add to her 2019 French Open crown, Australian star Barty claimed her ninth WTA Tour trophy and second on home soil.

"It was some of the better tennis I played throughout the whole week," Barty, who had not played in a competitive tournament since last February, told reporters in her post-match news conference.

"Garbine forced me to play at that level. It was a great final."

Barty added: "Overall it was a pretty solid performance. I'm still my harshest critic at times. That's the challenge of sport every day, is trying to get better and better."

Elsewhere in Melbourne, Elise Mertens clinched the Gippsland Trophy with a 6-4 6-1 win over Estonian veteran Kaia Kanepi.

Mertens – the seventh-seeded Belgian – returned to the winner's circle following two runner-up finishes in 2020.

As for Anett Kontaveit and Ann Li, they shared the Grampians Trophy on Sunday.

The Grampians Trophy did not have a final, the WTA announced, due to time running out before the Australian Open begins. Thursday's play was cancelled as a precautionary measure after a case of coronavirus involving a worker from a hotel that had housed quarantining tennis stars.

Kontaveit outlasted fifth seed Maria Sakkari 2-6 6-3 11-9 in the first semi-final, while Li upset seventh seed Jennifer Brady 7-6 (7-5) 6-7 (5-7) 10-6.

Has the time come for a former world number one to end her wait for a first grand slam title since becoming a mother?

It is a question that has been asked time and again since Serena Williams returned in 2018 following the birth of her daughter, Alexis Olympia.

The legendary American must have long since become tired of being asked whether she can match Margaret Court's record of 24 major singles triumphs, with her last success coming when she was pregnant at the 2017 Australian Open.

While the 39-year-old - beaten in four grand slam finals after coming back to the tour - will be expected to mount a challenge over the next fortnight, it could be another mother who is celebrating at Melbourne Park.

It is eight years since Victoria Azarenka claimed her second grand slam title at the Australian Open, but the 31-year-old has shown there could be more to come.

Azarenka beat Williams for the first time in a major to reach the final of the US Open last year, but she then endured the agony of losing to Naomi Osaka.

That was her first championship match at a grand slam in seven years, having given birth to her son, Leo, late in 2016 before a prolonged child custody dispute badly disrupted her career.

A resurgent Azarenka took her tally of WTA Tour singles titles to 21 by winning the Western and Southern Open last August and was named the Comeback Player of the Year for 2020, as she headed back towards the peak of her powers.

The world number 13 claimed both of her grand slam titles at the Australian Open and will face Jessie Pegula in the first round next week.

Azarenka said she is enjoying her tennis more than ever and Michael Joyce, her former coach, believes she has a great chance of making a dream start to the year.

Joyce, who also coached Pegula, told Stats Perform News: "Vika has got as good a chance as anyone in Australia. She's back at the top, where she belongs.

"She won the Western and Southern and came so close at the [US] Open. She's also had some very tough draws as she's worked her way back, so she's done incredibly well to get back where she is.

"Opponents won't want to play her. If Vika gets through a couple of rounds, she can be very dangerous. Once she gets momentum, she can be hard to stop."

The great Martina Navratilova declared after Azarenka's run to the final at Flushing Meadows that she had witnessed "a new Vika" with extra punch in her shots" and "stronger than ever before".

Azarenka's positive outlook has also been evident off the court, as she recently launched a 'Think About It' podcast series, in which she engaged in in-depth conversations with the likes of motivational guru Trevor Moawad and professional rock climber Sasha DiGiulian.

The aim of the series was for Azarenka and her audience to learn from 'power players' in a variety of industries and show the strength that can be forged from vulnerability.

Azarenka's rivals may be feeling vulnerable in Melbourne as they think about how to go about beating the Belarus-born star.

Daniil Medvedev won a marathon match against Alexander Zverev to send Russia into the final of the ATP Cup for the first time.

The world number four and reigning ATP Finals champion triumphed 3-6 6-3 7-5 at Melbourne Park in a match lasting just under two hours and 40 minutes.

That result clinched victory over Germany in the semi-final after Andrey Rublev had earler fought back in style from a set down to defeat Jan-Lennard Struff 3-6 6-1 6-2.

"We're really happy to get the win, that's the most important [thing," Medvedev said. "Tough matches [for] both of us. Both [Andrey and I] lost the first set. [It was] not easy, because we had two days off before the match. But happy we're in the final. That's the most important."

Zverev appeared in control after breaking to go 3-2 ahead in the second set after winning the first, but Medvedev reeled off four games in a row as the world number seven began to struggle with a lower back problem.

"When it's against Sascha and you are 6-3, 3-2, break down, many times you're going to lose a match," Medvedev said. "But I needed to keep my chances alive for the team first of all, for the country. I just tried to stay there, got a bit tight maybe. I just did my job and I'm really happy about it."

Russia will meet Italy in the final following their defeat of Spain, which was secured by Matteo Berrettini's straight-sets win over Roberto Bautista Agut.

After Fabio Fognini saw off Pablo Carreno Busta in three sets, Berrettini - who has beaten three of the top 13 players in the world without dropping a set in this tournament - won 6-3 7-5 to set up Sunday's Russia showdown.

"It's an unbelievable feeling," said a delighted Berrettini, who was absent last year as Italy failed to progress from their group in the inaugural staging of the event. "Last year I couldn't make it, so I'm really happy that the first time that I played we are into the final.

"I'm feeling good. I'm feeling pumped. I'm feeling great to play not just for me, but for my team and for Italy in general. That's what matters the most. I'm really looking forward to playing tomorrow."

SINNER TO FACE FAMILIAR FOE

There will be an all-Italian affair in the final of the Great Ocean Road Open, with Jannik Sinner to face Stefano Travaglia.

In-form Sinner clinched an impressive 7-6 (7-4) 4-6 7-6 (7-4) win over second seed Karen Khachanov, in a three-hour battle, after his compatriot beat Thiago Monteiro 6-3 6-4.

At the Murray River Open, Felix Auger-Aliassime will meet Dan Evans in the final as each look to secure a first ATP Tour title.

Auger-Aliassime needed only 61 minutes to beat Corentin Moutet, while eighth seed Evans required a minute less to ease past Jeremy Chardy.

Rafael Nadal has history in his sights, but Novak Djokovic stands in his way at an Australian Open he has almost made his own.

With Roger Federer absent from the year's first grand slam, all eyes in the men's draw will be on Nadal and Djokovic.

As the fight between the 'Big Three' continues as to who will finish their career with the most majors, Melbourne shapes as again playing a key part, particularly amid the ongoing uncertainty due to the coronavirus pandemic. After winning his 13th French Open last year, the equation is simple for Nadal. His success at Roland Garros drew him level with Federer on 20 majors, the most by a man all-time.

But with the GOAT debate sure to continue for decades to come, a second title in Melbourne would also lift the Spaniard into uncharted territory. Nadal has the chance to become the first man in the Open Era to win every grand slam at least twice. Federer and Djokovic are both missing a second crown at Roland Garros.

For all his dominance in Paris, that would add another feather to the cap for 34-year-old Nadal. Most of Federer's major success has come at Wimbledon (eight titles), while Djokovic's has been at the Australian Open (also eight titles) – both establishing men's records at those tournaments. Nadal has been runner-up four times in Melbourne since his only title in 2009, while he has reached at least the quarter-finals in the past four years.

But just as Nadal, who is dealing with a back injury ahead of the tournament, stands in the way at the French Open, he will need to get past Djokovic – or have some luck – in Australia.

The Serbian has a 75-8 win-loss record at the tournament, including winning the past two titles. He has won the crown every time he has reached the semi-finals. Djokovic's previous blip in Melbourne came in 2017 and 2018, surprisingly beaten by Denis Istomin (second round) and Chung Hyeon (fourth round) respectively.

A year younger than Nadal, Djokovic is a 17-time grand slam champion, and he has made no secret of his desire to hold the record for most majors won by a man. Djokovic and Nadal have claimed nine of the past 10 majors, although the other one came recently as Dominic Thiem clinched last year's US Open, where the Spaniard and Federer were absent.

With preparations impacted by COVID-19, perhaps Thiem, Daniil Medvedev, Stefanos Tsitsipas, Alexander Zverev or Andrey Rublev could threaten as the wait goes on for a changing of the guard in men's tennis.

But all eyes are unsurprisingly on Nadal and Djokovic as history again beckons.

Garbine Muguruza continued her impressive form to book a meeting with Ash Barty in the Yarra Valley Classic final.

Muguruza, the Spanish sixth seed at the WTA 500 event, crushed Marketa Vondrousova 6-1 6-0 on Saturday.

The two-time grand slam champion has lost just 10 games in four matches on her way to the final.

Muguruza lost just eight points on serve against Vondrousova while converting five of 11 break points.

She will meet Barty in the final after the Australian benefited from Serena Williams' withdrawal as the 23-time grand slam winner deals with a shoulder injury.

Naomi Osaka and Victoria Azarenka also withdrew on Saturday from the Gippsland Trophy and Grampians Trophy respectively.

At the Grampians Trophy, Anett Kontaveit was given a passage into the semi-finals, where Maria Sakkari awaits after her 6-4 6-2 win over Angelique Kerber.

Jennifer Brady and Ann Li will meet in the other semi after wins over Barbora Krejcikova and Sorana Cirstea respectively.

Elise Mertens will play the Gippsland Trophy final after Osaka's withdrawal with the Belgian to face Kaia Kanepi, who overcame Ekaterina Alexandrova 6-3 7-6 (8-6) to reach her first WTA decider since 2013.

Naomi Osaka said the scheduling of lead-up events was a factor in her decision to withdraw from the Gippsland Trophy on Saturday.

The three-time major champion opted to pull out of her scheduled semi-final against Elise Mertens due to a shoulder injury.

Osaka, 23, was due to play a fourth match in five days, but decided to withdraw ahead of the Australian Open starting on Monday.

"Anyone that's kind of followed me for a bit knows that I've kind of had a slight shoulder thing since like 2018 in Beijing," the Japanese star told a news conference.

"It kind of flared up again because I played a lot of matches back-to-back. But, for me, my main focus is hoping I can rest enough before the Open."

Osaka, who will face Anastasia Pavlyuchenkova in the Australian Open first round, said the time between the Gippsland Trophy and year's first major also impacted her decision.

"I would say it is a factor because for me, I don't normally play the tournament right before a slam," she said.

"But I felt like it was really necessary to get matches in. I think everyone felt that way.

"I'm kind of sad that I wasn't able to play today. But I think in the end it's the right decision."

Serena Williams admitted she would be dealing with her shoulder injury during the Australian Open, but the star is "very confident" she will be ready to go.

Williams withdrew from the Yarra Valley Classic on Friday due to a right shoulder injury.

Asked how she was feeling on Saturday, the 23-time grand slam singles champion was upbeat.

"I feel pretty good. I've gotten a lot of treatment already on my shoulder.  But I'm super confident it's going to be great," Williams told a news conference.

"I'm feeling very confident, I think is a better word, and getting ready for hopefully the next two weeks."

However, Williams said the injury would be an issue throughout the Australian Open, which begins on Monday.

"It's definitely something that I'm going to have to deal with for the fortnight. Kind of knowing that going into a tournament definitely helps," the 39-year-old said.

"Also knowing, okay, I'm going to have to probably pick up some different therapy exercises after each match, etcetera.

"It's going to be really important."

Williams' last grand slam title came in Melbourne in 2017 and all eyes will again be on the American in her bid to equal Margaret Court's record of 24 major crowns.

While that record is again on her mind, Williams – who will face Laura Siegemund in the first round – said she was now more relaxed about it.

"It's definitely on my shoulders and on my mind. I think it's good to be on my mind," she said.

"I think it's a different burden, I should say, on my shoulders because I'm used to it now. It's more relaxing I would like to say, yeah."
