Novak Djokovic has brought up his 378th week as world number one.

That sees the 35-year-old, 22-time grand slam champion overtake Steffi Graff as the outright record holder for the amount of weeks spent at the top of the world.

Djokovic won his first major in 2008, and has not looked back.

To mark his achievement, Stats Perform has used Opta data to run through the key numbers from Djokovic's stellar career.

ATP Tour titan

7 - Djokovic has been year-end number one on seven occasions, one more than Pete Sampras and two more than Roger Federer, Rafael Nadal and Jimmy Connors.

93 - Djokovic has won 93 ATP Tour titles. Only three players have won more in the Open Era.

1,249 - The Serbian has played 1,249 matches on the ATP Tour. Just Nadal (1,288), Ivan Lendl (1,310), Federer (1,526) and Jimmy Connors (1,558) have played more.

350 - Djokovic has featured against top-10 opponents 350 times, more than any other player in history. He has won 243 of these matches. 

A master at work

22 - Only Serena Williams (23) has more major titles in the Open Era than Djokovic, who is tied with Nadal for the most grand slam triumphs when it comes to men.

33 - Djokovic has played in 33 grand slam finals, the most by any male player in the Open Era. Only Chris Evert (34) has more when it comes to female players.

37 - He has won 37 per cent of the grand slam titles on offer since (and including) his maiden major success in Melbourne in 2008. Nadal has won 32 per cent (19/60) and Feder 13 per cent (8/60).

28 - No player has won more consecutive matches at the Australian Open than Djokovic (28), while he has won 28 straight at the Wimbledon, too.

10 - Djokovic is the first player to play a minimum of 10 semi-finals at each of the grand slams.

38 - No player has won more ATP 1000 titles than Djokovic (38), Eleven of those titles were won without losing a set.

6 - Djokovic has won the most ATP 1000 titles won in a single season (six).

Nemesis Nadal

179 - Djokovic has faced players from Spain 179 times, winning 131 matches and losing 48.

29 - He has won 130 matches against left-handed players, losing 40. Of those 40 defeats, 29 were inflicted by Nadal.

100 - Djokovic has a 100 per cent record against four players: Gael Monfils (18-0), Jeremy Chardy (14-0), Milos Raonic (12-0) and Andreas Seppi (12-0).

Cameron Norrie was not the only opponent Carlos Alcaraz had to overcome in the Argentina Open final, as he battled feelings of guilt after not doing "the right things" to recover from injury.

Alcaraz made it one title from one tournament in 2023 as he overcame Norrie 6-3 7-5 in Buenos Aires on Sunday.

Last year's US Open champion dropped just one set through the tournament as he marked his return to action in style, with the 19-year-old having missed the Australian Open due to a hamstring issue.

Alcaraz had not featured since November, and the world number two admitted he did not feel his application during his extended break was always as good as it should have been.

"This trophy is special. During those four months I had a hard time and I didn't do the right things off the court, and I felt a bit guilty after the injury," Alcaraz said.

"Fighting against this is not easy. Coming here, my first tournament after four months, and winning the first tournament since the US Open is very special for me."

Alcaraz won seven games on the bounce to swing the final in his favour, and believes he hit peak performance during the match.

"I felt very comfortable playing the final," Alcaraz added.

"I knew that it was going to be really difficult. I started really focussed on what I had to do at the beginning, my game, my level. 

"This is the level that I have to play in finals."

Alcaraz has already collected seven titles in his young career, with five of those coming on clay.

His idol and compatriot Rafael Nadal won 13 clay-court tournaments prior to turning 20.

Combined with Alcaraz's haul, that total of 18 betters the 13 managed by all other players combined on the ATP Tour in the 21st century before turning 20.

Alcaraz is now set to play in the Rio Open, where he is the reigning champion, this week.

Dominic Thiem insists Novak Djokovic must be regarded as the greatest tennis player of all time, ruling Roger Federer and Rafael Nadal out of contention.

Despite a hamstring issue, Djokovic became the joint-most successful male player in grand slam history last week as he moved level with Nadal on 22 titles following his record-extending 10th Australian Open triumph. 

Along with retired 20-time major winner Federer, Djokovic and Nadal find themselves in the long-running debate to determine the greatest player in history.

But 2020 US Open champion Thiem, who believes the number of major wins must be the decisive factor in the conversation, is confident Djokovic will soon leave his two great rivals firmly behind.

"In my opinion, the grand slam titles should be the defining criteria when determining the best of all time, they are the four most important tournaments in tennis," the Austrian said.

"Everything else is fine, but it's not the same. The slams are what counts, so the GOAT will probably be the one with the most grand slams.

"I am not very surprised [by Djokovic's Melbourne triumph]. Djokovic still looks young – physically and mentally, because of the way he moves on the court. It's like he was 25 years old.

"We have to be honest, he is the best, so his victory was not very surprising."

Rafael Nadal has congratulated Novak Djokovic on the "amazing achievement" of matching his record tally of 22 grand slam titles by winning the Australian Open on Sunday.

Djokovic and Nadal share the record for the most major tournaments won by a male player after the 35-year-old beat Stefanos Tsitsipas 6-3 7-6 (7-4) 7-6 (7-5) at Melbourne Park.

The Serbian superstar also returned to the top of the rankings by being crowned Australian Open champion for a record-extending 10th time.

Djokovic and Nadal will head to the French Open in May eyeing major triumph number 23.

Spaniard Nadal, who will be out for around eight weeks due to a hip injury he aggravated during a second-round loss to Mackenzie McDonald in Melbourne, posted on Instagram: "Amazing achievement Nole @djokernole Many congrats to you and your team!

"Well deserved. Enjoy Nole!"

Swiss great Roger Federer, a winner of 20 major titles before retiring last year, also saluted Djokovic in an Instagram story on Sunday: "Incredible effort, again! Many congratulations." 

The legendary Margaret Court leads the way with 24 major singles titles, while Serena Williams racked up 23 in her incredible career.

Stefanos Tsitsipas paid tribute to Novak Djokovic after losing to the Serbian in Sunday's Australian Open final, lauding him as the "greatest that ever held a tennis racquet".

Djokovic was at his dominant best as he drew level with Rafael Nadal on 22 men's grand slam singles titles thanks to a straight-sets win over Tsitsipas at Melbourne Park.

The 35-year-old won 6-3 7-6 (7-4) 7-6 (7-5) at Rod Laver Arena to make it 10 wins from as many Australian Open finals.

Djokovic was barred from defending his own crown last year when deported from Australia due to his COVID-19 vaccination status, but he returned with a vengeance in 2023, dropping just one set across seven matches as he also reclaimed the world number one spot.

But most importantly it put him level again with Nadal in terms of major titles after the Spaniard won in Melbourne and Roland Garros last year.

Despite this parity, Tsitsipas has no doubt who he believes is the best to ever play the sport.

"Novak, I don't know what to say. It speaks for itself what you have achieved so far," said the 24-year-old, whose wait for a maiden grand slam title continues. "It's all in the numbers.

"Congratulations, not only to yourself but having such a supportive family. I think it is very similar the way we grew up around tennis, so it's been an unbelievable journey for you.

"I admire what you've done for our sport, and I think you make me a better player when are on court.

"I have had the privilege to play a lot of difficult and high intensity matches, but I would like to say one more time Novak brings out the best in me.

"He's one of the greatest in our sport, and he's the greatest that has ever held a tennis racquet, for sure.

"I'd like to thank you for pushing our sport so far. I think it deserves a player like you who pushes every single player that's involved in the sport to the max."

Tsitsipas, who was bidding to become the 27th male singles champion at the Australian Open, had his moments as he forced set point in the second and broke Djokovic at the start of the third.

But Djokovic's famed powers of recovery were as strong as ever, and Tsitsipas – beaten by the same opponent in the 2021 French Open final – quickly turned his attention back to the daily grind.

"It's not easy, another final at a grand slam, but I am always willing to go back on court and work harder," he continued. "I would like to thank my team for coming on this journey with me.

"I am happy I have group of supportive people around me, people who wake up every single day and have the same goals and ambitions as me. I'm extremely privileged that I get to do this for a living."

Novak Djokovic will play his 33rd grand slam final on Sunday, extending his men's Open Era record and edging closer to Chris Evert's leading mark across all singles players.

Djokovic beat Tommy Paul at the Australian Open on Friday to advance to a 10th Melbourne final, having won each of the prior nine.

The Serbian has also played nine title matches at the US Open, eight at Wimbledon and six at the French Open.

Even before this latest semi-final success, his tally of 32 major men's singles finals was unmatched in the Open Era.

But the 33rd saw Djokovic match Serena Williams in second place among both male and female players, with only Evert out ahead now on 34.

Djokovic will no doubt back himself to reach and perhaps pass that record before the year is out, with Roger Federer having retired and Rafael Nadal injured again – those two great rivals no longer keeping pace with the 21-time slam champion. A 22nd success on Sunday would equal Nadal's record.

With victory over Paul, Djokovic joined Federer and Nadal as the only male players in the Open Era to reach 10 or more finals at one major.

Federer went to 12 Wimbledon finals, while Nadal has played the title match at Roland Garros on 14 occasions.

Rafael Nadal remains on course to return to action in March after undergoing further tests on the hip flexor injury he sustained on his way out of the Australian Open.

The 22-time major winner failed to defend his crown in Melbourne after losing 6-4 6-4 7-5 to world number 65 Mackenzie McDonald last week.

Nadal struggled to move around the court in the closing stages of the match and revealed afterwards he had aggravated an issue he had been suffering with for a couple of days.

An MRI scan showed the Spaniard had a grade two iliopsoas tear in his hip flexor, which would usually mean between six and eight weeks out of action.

After returning home to undergo further checks on Thursday, Nadal confirmed he is on course to return in that initial timeframe.

"Today I have been at the Tecknon Tennis Clinic in Barcelona where they have carried out some tests on me," he posted on his personal Twitter page.

"The Melbourne results are confirmed and the deadlines remain the same. I've established the treatments to follow and in three weeks they will perform new tests to see the evolution."

Nadal faces a battle getting back to full fitness in time for the Indian Wells and Miami Masters 1000 events in March.

Those were due to be preceded on his schedule by a high-profile exhibition match in Las Vegas against Carlos Alcaraz, who is also currently injured, on March 5.

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 last week. 

"I can't say that I am not destroyed mentally at this time, because I will be lying."

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.

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."

Rafael Nadal refused to retire from his second-round match at the Australian Open despite suffering a hip injury in his shock defeat.

The reigning champion and top seed in Melbourne crashed out on Wednesday, going down 6-4 6-4 7-5 to world number 65 Mackenzie McDonald.

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

The 36-year-old confirmed he aggravated an issue he had been suffering with for a "couple of days" prior to his meeting with McDonald.

Nadal could well have handed McDonald a walkover, but explained that as defending champion, he did not want to go out without a fight.

"I considered all the time stopping, but I didn't ask," he said in a press conference. "I have to know myself, and I tried to keep playing without increasing the damage.

"I was not able to hit the backhand at all. I was not able to run for the ball. But I just wanted to finish the match. That's it.

"I didn't ask them [his team]. I am old enough to take my own decisions. I didn't want to retire, [as] defending champion here. No, I didn't want to leave the court with a retirement.

"It's better like this. I lost. Nothing to say. Congratulations to the opponent. Just try your best till the end, it doesn't matter the chances that you have.

"That's the philosophy of the sport. That's the essence of the sport by itself. I tried to follow that during all my tennis career, and I tried of course to not increase the damage, because I didn't know what's going on."

Nadal, who is the first top seed to go out in the second round of the Australian Open since Gustavo Kuerten in 2001, is unsure as to the extent of his injury.

"I don't know what's going on, if it's a muscle, if it's a joint. I have history in the hip, I had issues. I had to do treatments in the past," he said.

"Now I feel I cannot move. But I don't know till I do the test and all this stuff, I don't know. I don't know.

"I'm tired of talking about it. I understand, but I lost the match. That's it. I tried until the end. I don't know if in good condition I would win the match. I will have better chances without a doubt."

Nadal added that he would be "lying" if he said he had been mentally destroyed by the issue, given the comfort of his life outside tennis.

However, the 22-time grand slam champion is still motivated to return to the court.

"It's a very simple thing: I like what I do. I like playing tennis," he added.

"I know it's not forever. I like to feel competitive. I like to fight for the things that I have been fighting for almost half of my life or even more. 

"It's not that complicated to understand, no? When you like to do one thing, sacrifices always make sense. When you do things that you like to do, at the end of the day, it's not a sacrifice. You are doing the things that you want to do. Sacrifice is when you are doing things that you don't want to do."

The Spaniard conceded another long spell away from the court would be difficult, though.

He said: "Of course it's tiring and frustrating to spend a lot of [this] part of my career recovering and trying to fight against all this stuff all the time.

"I have had seven months playing almost nothing, and then if I have to spend a long time again, then it's super difficult in the end to be in rhythm and to be competitive and to be ready for the fight. Let's see how the injury is, and then let's see how I can manage to follow the calendar."

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

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

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

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

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

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

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

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

Rafael Nadal says winning matches is the perfect cure to his injury problems after kicking off his Australian Open title defence with victory in four sets against Jack Draper.

Top seed Nadal's class told on Rod Laver Arena in a match lasting three hours and 43 minutes as he prevailed 7-5 2-6 6-4 6-1 to reach the second round for the 17th time.

The 36-year-old was competing for just the eighth time since September's US Open, with Monday's victory over Draper his first of 2022.

Not only has Nadal spent time recuperating from injuries, he is also adapting after becoming a father for the first time in October.

However, in his first grand slam since the birth of his child, Nadal says simply winning trophies is providing him with all the motivation he needs.

"I am enjoying life having a new member in the family," he told reporters. "I've always loved kids. To be able to enjoy this new moment in my life is something beautiful.

"But in terms of competitive feelings or motivation, it doesn't create any impact. It'd only create a negative impact if I was here a month, and they were not able to be with me. 

"You don't know how you're going to react, you know? I've always been very respectful with the changes in life. You don't know how you're going to adapt. 

"I don't know my feeling if the baby's not here with me for one month. I don't know if after three weeks I miss him, and I'll lose a little bit the focus.

"I have always been excited enough to play every single tournament. My approach to the competition is not changing much being a dad or not."

Nadal has now lost only one of his 18 matches at this stage of the Australian Open, with that defeat coming at the hands of Fernando Verdasco in 2016.

The record 22-time major winner did not have it all his own way against Draper, who appeared to be heavily affected by cramp later in the match.

He was not always at his confident best and made some uncharacteristic errors to allow his British opponent back into the match, but he ultimately got the job done.

"I am ready to keep fighting," Nadal said of his recent injury issues. "Victories help. When you win matches, you are more relaxed and you are more confident.

"I needed a victory, so that's the main thing. It doesn't matter the way it happens. The most important thing today is a victory against a tough opponent."

Draper levelled up the match at 1-1 and in the process became one of only 12 players to have taken a set off Nadal at this stage of a grand slam.

"As I said before the tournament started, this was one of the toughest first rounds possible being seeded," Nadal said.

"To win against Jack, I needed to do things well. I think I did things well. So I'm satisfied with the victory because that's give me the chance to play again in a couple of days.

"I accepted the mistakes I made. I was humble enough to accept that there was going to be a little bit of ups and downs during the match. 

"This is typical when you're not in a winning mood. When you lose more, when you are not competing every week, that's the case. I accept these mistakes and keep going."

Nadal will now face Mackenzie McDonald in the last 64 after the American beat compatriot Brandon Nakashima in a five-set thriller.

Rafael Nadal secured his first win of the year as he began the defence of his Australian Open title by beating Jack Draper 7-5 2-6 6-4 6-1.

The number one seed did not have it all his own way against the Briton, but ultimately the class and fitness of the 36-year-old made the difference as Draper – 15 years Nadal's junior – appeared to be heavily affected by cramp later in the match.

Nadal had lost six of his last seven tour-level matches coming in, but gained the advantage after he managed to break at 6-5 up in an even first set against the big-serving Draper.

Draper fought back emphatically as he raced into a 4-0 lead in the second, seeing it out comfortably to level up at 1-1, but he appeared to start cramping just two games into the third set.

Nadal took advantage and went 4-1 ahead, but the Spaniard did not always seem at his confident best himself as some uncharacteristic errors allowed his opponent back in, with Draper breaking back and managing to get to 4-4.

Nadal was able to break again to take the set 6-4, and despite Draper breaking serve in the opening game of the fourth, that was his last success of the match as the 21-year-old's legs clearly started to affect his movement and serve, with Nadal finding it simple enough to close out the win.

Data slam: Nadal matches Lendl for career wins

This was the 1,068th win of Nadal's career, bringing him level with Ivan Lendl.

The 22-time grand slam winner is now tied for third most victories in the Open Era, behind only Jimmy Connors (1,274) and Roger Federer (1,251).

Rafael Nadal has denied he has already decided to follow Roger Federer into retirement after this year's French Open.

The Spaniard wil turn 37 in June, and calling time on his career at the grand slam he has won a record 14 times might be the ideal way to sign off.

Making predictions for the season, Germany's Alexander Zverev told Eurosport: "Unfortunately, I think Rafa will retire at Roland Garros. I don't want it to happen, but I think he will have a great tournament, potentially win it and say goodbye."

That would mean Nadal joining his former great rival Federer in waving goodbye to a glorious career after the Swiss played for the last time at the Laver Cup in September. Nadal's tears that night in London pointed to a realisation his own time on tour was also nearing its end.

However, Nadal denies Zverev has been given any encouragement to throw out such a specific retirement suggestion, which was revealed ahead of the Australian Open.

Nadal is the defending champion in Melbourne, and he also took the Paris slam last year to reach 22 for his career, putting him one ahead of Novak Djokovic.

"I don't know what's going to happen in six months," Nadal said, quoted by Eurosport.

"I have a very good relationship with Zverev, but not enough to confess something like that to him.

"The reality is that I'm here to play tennis, try to have a great 2023, fight for everything that I have struggled throughout my career, and I don't think about my retirement.

“You think about it week after week because that's how you show me at every press conference. But I will answer the same every time you ask me."

Nadal has lost six of his last seven tour-level matches, suggesting he might struggle to make serious inroads in his title defence, which starts against Britain's Jack Draper on Monday.

Asked if he felt vulnerable, Nadal said: "Yeah, of course. Without a doubt. I have been losing more than usual, so that's part of the business.

"I think I am humble enough to accept that situation and just work with what I have today. I need to build again all this momentum. I need to build again this confidence with myself with victories. But it's true that I have been losing more than usual.

"I already have been here for three weeks, practising every day with the conditions, with the best players. That helps a lot in general terms.

"My situation, I don't know what can happen on Monday, but my personal feeling, without a doubt, is better now than three weeks ago, in general terms."

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.
