Novak Djokovic may have missed out on completing a Grand Slam in 2021 but his "crazy" achievements across the year have received praise from Roger Federer. 

Djokovic fell at the final hurdle in his bid to secure a clean sweep of the majors, losing in straight sets to Daniil Medvedev at the US Open.

The Serbian's defeat at Flushing Meadows means Rod Laver remains the last man to claim all four majors in one year, the Australian doing so for a second time in 1969 having previously managed the feat seven years earlier. 

Neither Federer, who missed out on playing in New York due to knee surgery, nor Rafael Nadal have done so in their stellar careers, though the Swiss is certain a calendar slam is still possible.

"Will it actually happen again, that a player will win all four grand slams in their career? I think so," Federer said.

"We have seen with Rafael Nadal, Novak Djokovic and of course with me as well that this is possible.  

"It is extremely hard, of course. But I have the feeling, more than ever, that we can dominate on all kinds of ground where we have all found our own game.  

"The problem is mentally and physically it is not getting any easier for any of us. So, what Novak was able to accomplish this year has to be highly rated. It was absolute top class. It was crazy." 

Federer confirmed he would be out for "many months" when revealing he would require a third procedure on his problematic right knee in the space of 18 months.

However, the 40-year-old – who sits tied with long-time rivals Djokovic and Nadal on 20 grand slam singles titles – has suffered no setbacks in his recovery so far, putting him on course for a competitive return to the ATP Tour in the 2022 season.

"I'm feeling actually really good, considering, you know, that things are not as I hoped they would be, but I'm recovering well and the rehab is going really good, I must say," Federer said. 

"I've had no setbacks. You know, every day is a better day. I'm feeling strong and excited for what's to come."

Federer has not played since losing in straight sets to Hubert Hurkacz in the Wimbledon quarter-finals back in July.

Novak Djokovic was "playing for history" and suffered from nerves in his US Open final defeat to Daniil Medvedev, according to previous champion Dominic Thiem, who backed the 34-year-old to return "stronger than ever" in 2022.

Medvedev prevented Djokovic from becoming the first man since Rod Laver in 1969 to win all four grand slams in a single year, beating him 6-4 6-4 6-4 in Sunday's thrilling showpiece.

Djokovic was seen in tears during the third set as his hopes of adding the US Open to his run of wins at the Australian Open, French Open and Wimbledon this year slipped away.

But Thiem tipped Djokovic to bounce back from the disappointment of defeat and return in 2022 even stronger.

"One unbelievable goal slipped out of his hands yesterday," Thiem told Stats Perform.

 

"I expect him to be as strong as ever in 2022. I think after he won in Roland Garros, everybody was only talking about the calendar slam – first about the golden slam, and then about the calendar slam.

"He [Djokovic] was under pressure. Nobody can feel that or anything like that because of it being the calendar slam.

"I can feel it in a smaller way, probably from last year's final and from some other matches. And at some points it's just getting to you. And so, I really felt for him as well towards the end of the match.

"So, it can happen that it also makes him even stronger next year when all these talks and all this pressure is not that big anymore."

Thiem, who missed the tournament with a wrist injury that will rule him out until 2022, believes nerves were a factor in Djokovic's defeat but agreed with Medvedev's assessment of the Serbian as the greatest of all time – though he could not set him apart from Roger Federer and Rafael Nadal.

"For me, there are three GOATs in the game, and each of them has achieved something very unique," Thiem said of the trio locked on 20 major titles each.

"So it's still the same for me as it was before. The three of them are the best in the history to me.

"And I'm only super happy to be in the same era with them and to be able to compete with them. Hopefully many more times next year again."

Daniil Medvedev was relieved to close out his first grand slam title at the US Open after revealing he was cramping in his quest to conquer Novak Djokovic.

Medvedev blitzed world number one and 20-time major champion Djokovic 6-4 6-4 6-4 in the men's final at Flushing Meadows on Sunday.

Djokovic's bid to become just the third man and first since Rod Laver in 1969 to claim a calendar Grand Slam, and to surpass Roger Federer and Rafael Nadal for the most major men's titles, was emphatically ended by Medvedev.

Medvedev fired down 16 aces and hit 38 winners in a ruthless display on Arthur Ashe Stadium. However, the second seed conceded he was worried at the end of the third set as he tried to see off Djokovic.

Russian star Medvedev double-faulted twice in succession when his first championship point arrived and gave back one of those breaks to Djokovic, who closed to 5-4. But the former came out to serve again and again served a double on a championship point, though he had another in store and the Serb netted on the backhand.

"I definitely had it [pressure]," Medvedev – who lost to Djokovic in the 2021 Australian Open final, having gone down to Nadal in the 2019 US Open showpiece – told reporters. "I started cramping at 5-3, I think because of the pressure at 5-2 where I had match points, I didn't make it. My legs were gone after 5-3. At 5-4, left leg, I almost couldn't walk. If you really look the replay, when I walked to the towel, my leg was just going behind. I was trying not to show it. If Novak feels it, it's not good.

"Again, 40-15, that's two match points. I was like, C'mon, go for an ace, just try to make it. I had a huge double-fault. Second one was like in the middle of the net. Okay, I have one more. Just try to make a first serve. I made it and I'm really happy."

Medvedev became the first Russian man to win a grand slam since Marat Safin at the 2005 Australian Open.

The 25-year-old also became the ninth different men's champion of the last 14 years in New York, including first-time major winners Dominic Thiem, Marin Cilic, Andy Murray and Juan Martin del Potro. During the same time, the Australian Open, French Open and Wimbledon have each been claimed by four different men.

Medvedev – the second player since Ivan Lendl in 1987 to lose just one set en route to the men's US Open crown after Nadal in 2010 – is the fifth player to clinch a slam final against Djokovic.

He is also the fourth player with four or more wins over Djokovic as world number one, after Nadal (nine), Federer (five) and Murray (five).

"It definitely makes it sweeter [beating a world number one for first major trophy]," Medvedev said. "I mean, a grand slam is a grand slam. I would win it against Botic [Van de Zandschulp] in the final, probably I would be same happy.

"For the confidence and for my future career, knowing that I beat somebody who was 27-0 in a year in grand slams, I lost to him in Australia, he was going for huge history, and knowing that I managed to stop him it definitely makes it sweeter and brings me confidence for what is to come on hard courts so far, but let's see about other surfaces."

Medvedev was also asked about his celebration – the 13-time ATP Tour champion fell to the court after vanquishing Djokovic, with his eyes closed and tongue out.

It was in reference to FIFA's video game and the "dead fish" celebration.

"I like to play FIFA," he said. "I like to play PlayStation. It's called the dead fish celebration. If you know your opponent when you play FIFA, many times you're going to do this. You're going to score a goal, you're up 5-0, you do this one.

"I talked to the guys in the locker, they're young guys, super chill guys. They play FIFA. They were like, That's legendary. Everybody who I saw who plays FIFA thinks that's legendary. That's how I wanted to make it.

"Again, it's not because I want to be on the newspaper talking about FIFA celebration or whatever. I don't care. But I wanted to make it special for people to love, for my friends to love who I play FIFA with. I knew I'm going to make it. I got hurt a little bit. It's not easy to make it on hard courts. I got hurt a little bit, but I'm happy I made it legendary for myself."

Despite all appearances as he ploughed through the draws at all four grand slams this year, world number one Novak Djokovic does have a breaking point. 

Djokovic hit it on Sunday, falling 6-4 6-4 6-4 to Daniil Medvedev in the US Open final as the 20-time major champion finally proved unable to will himself out of an early hole. 

It was the fifth successive match in which Djokovic had dropped the opening set at Flushing Meadows, and the Serb superstar acknowledged afterward all of the energy he expended to get to the brink of the first men's calendar Grand Slam –since 1969 and a record 21st major title might finally have caught up with him. 

"Could be, could be [time spent on court a factor]. I had more hours on the court spent from Daniil, that's for sure," Djokovic said at his post-match news conference. "But was also emotionally very demanding period for me in the last five, six months. Slams and Olympics and playing at home in Belgrade.

"Everything was coming together for me here and kind of accumulating all the emotions that I've been through.

"Unfortunately I didn't make it in the final step. But when you draw a line, you have to be very satisfied with the year. Three wins, three slams and a final. For the last couple of years I've been very transparent and vocal about my goals, to play my best tennis at slams. I'm managing to do that.

"Of course, I was short today for another slam title, but I have to be proud with everything that my team and I have achieved. And in tennis we learn very quickly how to turn the next page.

"Very soon there are some more challenges, more things that are coming up. I have learned to overcome these kind of tough losses in the finals of slams, the ones that hurt the most."

This defeat sent a range of emotions surging through the emotional 34-year-old as he sat courtside while awaiting the trophy presentation. 

Asked what was going through his mind at that moment, Djokovic's initial answer was succinct. 

"Relief," he said. "I was glad it was over because the build up for this tournament and everything that mentally, emotionally I had to deal with throughout the tournament in the last couple of weeks was just a lot. It was a lot to handle.

"I was just glad that finally the run is over. At the same time I felt sadness, disappointment, and also gratitude for the crowd and for that special moment that they've created for me on the court."

Djokovic heaped praise on his opponent, saying he expects Medvedev to win more grand slams in the years ahead after the Russian broke through for his first.

That inevitably sparked thoughts of the coming generational change in the men's game, dominated for so long by Djokovic, Rafael Nadal (35) and Roger Federer (40).

With an astonishing 60 grand slam titles between them, their eventual departure from the stage will open up opportunities for Medvedev, Tokyo Olympics gold medallist Alexander Zverev and other younger players. 

Djokovic insisted he is not quite done yet, but he does believe that transition already is in progress. 

"The older guys are still hanging on," he said. "We're still trying to shine the light on the tennis world as much as we possibly can.

"I'm speaking on my own behalf. I still want to keep going, try to win more slams, play for my country. Those are the things that motivate me the most I think at this point.

"But the new generation, if you want to call them this way, is not anyone new. It's already current, established. Of course, they are going to take over.

"I think tennis is in good hands because they're all nice guys and very, very good, high-quality tennis players. They got something to offer on and off the court.

"We are hoping that the transition will be smooth in terms of the attention and the popularity of this sport. It's very important.

"We all, of course, want to win on the court, but at the same time we all at the top represent this sport. We need to be aware of that, take this responsibility and try to bring more fans to the world of tennis.

"At the end of the day that's what counts and that's what keeps our sport alive."

US Open champion Daniil Medvedev labelled Novak Djokovic the "greatest tennis player in history" after snapping the superstar's historic bid for a calendar Grand Slam.

Djokovic was seeking to become just the third man and first since Rod Laver in 1969 to claim all four majors in a year, however, the 20-time slam champion was swept aside by Medvedev 6-4 6-4 6-4 in Sunday's final at Flushing Meadows.

Medvedev showed no mercy as the world number two broke through for his first slam title, having lost to Djokovic in the 2021 Australian Open final and Rafael Nadal in the 2019 US Open decider.

As Medvedev celebrated his maiden major crown, the Russian star heaped praise on the beaten and emotional world number one – who shares the record for most men's slams alongside Nadal and Roger Federer.

"I think it's the first time I'm so nervous, saying my speech," Medvedev said during his trophy presentation in New York.

"First of all I want to say sorry for you, the fans, and Novak because I mean, we, we all know what he was going for today.

"What you accomplished this year and throughout your career – I never said this to anybody, but I will say right now for me: You are the greatest tennis player in history."

Medvedev became the first Russian man to win a grand slam since Marat Safin in 2005 on a memorable night.

The 25-year-old also became the ninth different men's champion of the last 14 years in New York, including first-time major winners Dominic Thiem, Marin Cilic, Andy Murray and Juan Martin del Potro. During the same time, the Australian Open, French Open and Wimbledon have each been claimed by four different men.

Medvedev – the second player since Ivan Lendl in 1987 to lose just one set en route to the men's US Open crown after Nadal in 2010 – is the fifth player to clinch a slam final against Djokovic.

"He is also the fourth player with four or more wins over Djokovic as world number one, after Nadal (nine), Federer (five) and Murray (five).

"Last but not least, I want to I want to finish my speech on a very sweet note. It's the third anniversary for me and my wife today," Medvedev added.

"You know, during the tournament I couldn't think of a present or anything, so when I went in the final, after semis, I thought okay if I lose, I need to find a present fast. ... I thought, well, if I lose, I have no time to have a present, so I have to win this match."

In Tokyo, it had been Alexander Zverev who denied Novak Djokovic his Olympic dream in a competition partially defined by controversy over the searing heat. In stifling temperatures inside Arthur Ashe Stadium on Sunday, the world number one saw his calendar Grand Slam hopes ended by a man often known for losing his cool.

Daniil Medvedev is among the most mercurial players on the ATP Tour. To watch Medvedev outwit his opponents when he is focused is one of the great joys of the modern game. When things go against him, though, his temper and his performance can unravel in a hurry.

To Djokovic's misfortune, in one of the biggest matches of his remarkable career, he came up against an inspired Medvedev enjoying obvious clarity of thought in a 6-4 6-4 6-4 win in the US Open final that means tennis' 'big three' remain locked on 20 grand slam titles apiece.

Medvedev is no stranger to heroics at tennis' largest stadium. Two years ago he enjoyed a rollercoaster journey in New York. Seeing red after being given a code violation for snatching a towel from a ballboy, Medvedev was mercilessly booed in a third-round match with Feliciano Lopez and openly goaded the fans thereafter in his on-court interview.

The booing continued in the subsequent round, but Medvedev's story that year was one of redemption, which ended with him receiving great credit for a remarkable near-comeback in a five-set epic final with Rafael Nadal.

Fast forward to a clash with another of the players firmly in the conversation for the best of all time and Medvedev sustained the levels he produced for two and a half sets against Nadal for three glorious sets as he ruthlessly took possession of a day that was supposed to belong to Djokovic.

Prior to the final, Djokovic had dropped the opening set in four of his previous matches at Flushing Meadows, winning three times in four sets and once in five.

As such, there was little reason not to expect a Djokovic comeback when Medvedev forged ahead in the showpiece.

However, in Medvedev, Djokovic found a foe completely unwilling to indulge his hopes of another recovery effort.

Coach Gilles Cervara labelled Medvedev a "genius" before the 2019 final and, when he plays as he did in clinching his first major title, it is tough to argue with that assessment.

As the elasticity of his movement enabled Medvedev to defend with an ease that belied the pressure of the occasion, Djokovic was simply unable to find a way through in the second set, which was decided with the artistry of the Russian's drop shot.

Djokovic could only hit into the tramlines having scurried in a desperate effort to meet such a shot, and that sense of desperation was evident when uncharacteristically poor play at the net from the Serbian gave Medvedev command in the third.

A pair of double faults played a role in Medvedev initially failing to serve out the match, the ice-cool focus escaping him for a brief moment, but there was to be no repeat when his second opportunity came as he finally clinched a maiden major on his third wedding anniversary.

So history denied. Not because of the heat, but because of a man keeping his cool in the face of the greatest challenge in the men's game and harnessing the genius that is now recognised by many more than just his coach. Extremely gracious in defeat, a potentially momentous day for Djokovic is now one he will want to forget. Instead, Medvedev and his wife have an anniversary to remember.

Novak Djokovic set aside the deep disappointment of missing out on the calendar Grand Slam by backing new US Open champion Daniil Medvedev to be a multiple major winner.

World number one and 20-time slam champion Djokovic had strung together a stunning run of wins at the Australian Open, French Open and Wimbledon, and he was a red-hot favourite to complete the set in New York.

A clean sweep of all four slams in a year had not been achieved since Rod Laver won the lot in 1969, and the great Australian was in the crowd as history appeared to beckon on Sunday.

Medvedev had other ideas and swept to a 6-4 6-4 6-4 win in two hours, 16 minutes, collecting his first title at this level but perhaps the first of many.

The world number two was tipped by a number of experts, including former world number one Jim Courier, to take the Flushing Meadows glory, and he came good as a flagging Djokovic paid the price for taking a circuitous route to the final.

Top seed Djokovic dropped the opening set of each of his matches from the third round onwards, spending more than five hours more on court than Medvedev on the way through the draw.

Speaking at the trophy presentation, Djokovic said: "I'd like to start off by saying congratulations to Daniil. Amazing. Amazing match, amazing tournament. If there is anyone that deserves a grand slam title now, it's you, so well done.

"You're one of the greatest guys on the tour. We get along very well. I wish you many more grand slams, many more majors to follow. I'm sure you will be on this stage in the future again."

Djokovic had appeared to well up before the final game of the match, on what was an emotional day for the Serb superstar.

He had demolished a racket in the second set as his rage grew, but come the end of the match he was looking to be sanguine.

Rather than airing his certain sense of frustration at falling just short of such a rare feat as a calendar Grand Slam, Djokovic looked for the positives.

And there was one that stood out, with the man who has often felt unloved by tennis crowds expressing his joy at the New York spectators showing him plenty of affection.

They had turned out in the hope of witnessing a famous moment in sporting history, which may have partly explained their raucous rallying behind the 34-year-old.

"I was thinking in both scenarios, kind of visualising myself standing here in front of you guys and what would I say," Djokovic told the crowd.

"I would like to say tonight that even though I have not won the match my heart is filled with joy and I am the happiest man alive, because you guys helped me feel very special on the court.

"You guys touch my soul. I've never felt like this in New York, I've never felt like this. Thank you so much for your support, everything you have done tonight for me. I love you and I'll see you soon."

Novak Djokovic fell agonisingly short of a clean sweep of this year's majors as Daniil Medvedev scored a sensational victory in the US Open final.

After scooping the Australian Open, French Open and Wimbledon titles, Djokovic arrived in New York in pursuit of the full set, but a 6-4 6-4 6-4 defeat meant the calendar Grand Slam dream died.

Rod Laver, the last man to achieve that feat in singles, back in 1969, was in the crowd to witness what most anticipated would be a momentous moment in tennis history. Instead, it was momentous for Medvedev, the Russian finally a champion at the highest level.

It means Djokovic remains tied with Roger Federer and Rafael Nadal on 20 slam titles, the 34-year-old being served notice here that a new generation is rising, headed by world number two Medvedev.

 It was a sizzling afternoon in New York, the temperature taking a leap a day on from Emma Raducanu's triumph in the women's final, and Djokovic was feeling the heat from the early moments.

Medvedev broke in the first game against a nervy and erratic opponent. Djokovic had said before stepping on court that he hoped to bring the "best version of myself" and promised he was "ready for the battle", but he was running on close to empty at times here.

Djokovic had dropped the opening set in the previous four rounds in this US Open run, winning three times in four sets and once in five during that sequence. He came into this match having spent five hours and 35 minutes longer on court than Medvedev, an unusually scenic route through the rounds for the top seed. And those extra miles in his legs showed, Medvedev swiftly a set ahead, sealing the opener with an ace.

Djokovic had won 10 of 10 matches in slams this year after losing the opening set. No man has ever won a slam after losing five first sets in the same tournament, the ATP said. That still holds true.

The Serbian had 0-40 on the Medvedev serve in the second game of the second set, but five points in a row from the man from Moscow felt like a bodyblow, and in the fourth game Djokovic's frustration spilled over, brutally smashing his racket three times against the ground.

Djokovic was landing only 50 per of first serves in court, and when he hit a feeble backhand into the net, Medvedev had two break points. He took the second of those when Djokovic looped a volley long, then held to love to lead 4-2.

On his third set point, Medvedev gave Djokovic a chance to make a passing shot, but the 34-year-old went wide. At two sets up, Medvedev may have had thoughts of Stefanos Tsitsipas losing from such a lead against Djokovic in the Roland Garros final, but this time Djokovic was fried.

He raced out to a double break and a 4-0 lead in the third set, yet double-faulted twice in succession when his first championship point arrived and gave back one of those breaks. Djokovic closed to 5-4, the New York crowd roared and the man who rarely feels loved by tennis crowds began to well up. Medvedev came out to serve again and again served a double on a championship point, but he had another in store and Djokovic netted on the backhand.

For the first time since 1990, when Pete Sampras and Gabriela Sabatini reigned over the rest, the US Open has a pair of first-time grand slam winners as its singles champion, with rookie Raducanu joined by the finished article in Medvedev.

In an extraordinary year for Djokovic, this was a lousy day.

Novak Djokovic is well aware of the history he is poised to make in Sunday's US Open final, and he is not shying away from it. 

After his 4-6 6-2 6-4 4-6 6-2 defeat of Alexander Zverev in the semi-finals Friday, a win in the final against Daniil Medvedev would make Djokovic the first player since Rod Laver in 1969 to win all four majors in the same year.

It would also give him a record 21st grand slam title, breaking the mark he shares with Roger Federer and Rafael Nadal. 

Two astonishing achievements, neither of which is complete just yet, as Djokovic reminded observers by invoking a famous Kobe Bryant line. 

"Job is not done," Djokovic said. "Excitement is there. Motivation is there, without a doubt. Probably more than ever. But I have one more to go."

Djokovic did cross one statistical milestone off the list with Friday's win. He has now reached his 31st grand slam final, equalling Roger Federer's record. 

Since falling to Kei Nishikori in the last four at the 2014 US Open, Djokovic is 17-1 in grand slam semis. 

Zverev lauded Djokovic for his mental toughness as the world number one improved to 36-10 in five-set matches, but the top seed said he still has to fight himself to stay in control in high-pressure situations. 

"It's kind of a hurricane, a tornado, of emotions that you're going through in a sequence of one set or even one point," Djokovic said. "You are by yourself on the court, so there is no escape.

"You've got to find a way. And I think, over the years, I have managed to develop a formula that works for me. ...

"Tennis is a very beautiful sport but a very demanding sport and you've got to have mind and body balanced at all times if you want to compete at the highest level for the biggest trophies."

Few can match him on that stage and he will attempt to reach even greater heights with a win Sunday. 

His opponent, the second-seeded Medvedev, has dropped only one set on the way to the final. 

Djokovic beat him in straight sets in January to win the Australian Open and deny the 25-year-old Russian his first grand slam title. 

History will be on the line Sunday at Arthur Ashe Stadium, and Djokovic is embracing it. 

"There's only one match left. ... Let's do it,'' he said. "I'm going to put my heart and my soul and my body and my head into that one. I'm going to treat the next match like it is the last match of my career.''

To hear Alexander Zverev tell it, he would have needed to be perfect to beat Novak Djokovic in the US Open semi-finals. 

In the end, a wobbly beginning to the fifth set proved the German's undoing in a 4-6 6-2 6-4 4-6 6-2 defeat Friday simply because Djokovic was at his best when it mattered most. 

Combine that enduring quality with the Serbian's incredible statistical record, said Zverev, and you have the greatest player of all time.

Djokovic will have a chance to solidify that case Sunday when he faces Daniil Medvedev for the title. 

A victory would make the 34-year-old the first player since Rod Laver in 1969 to win all four majors in the same year and give him a record 21st grand slam title, breaking the mark he shares with Roger Federer and Rafael Nadal. 

"I think it's great for the sport," Zverev said after his loss. "Nobody thought anybody will do it again, what Rod Laver did. To see ]Djokovic] have the chance on Sunday, I do believe that he will do it is great. He's breaking every single record that there is.

"If you look at the stats, if you look the pure game of tennis action, he's the greatest of all time.

"Nobody is there with him, because most weeks world number one, most Masters 1000s titles, most likely going to be the most grand slams at the end of the day.

"And he has the chance of winning all four in the same year. How do you compete with that?"

Zverev certainly tried Friday, becoming the first player to push Djokovic to a fifth set since Stefanos Tsitsipas in the French Open final. 

"I fought back," he said. "I left it all out there. ... I mean, the match could have gone both ways, but it went his way. Very often it does."

On this night, Zverev said, it was largely Djokovic's serve on big points that boosted the top seed. 

Whatever shots happened to be working better than others for Djokovic, though, one factor stood above the rest, as it usually does for him at grand slams. 

"I think mentally he's the best player to ever play the game," Zverev said. "Mentally, in the most important moments, I would rather play against anybody else but him."

Novak Djokovic is one win away from becoming the first man to complete a Grand Slam in 52 years. 

The world number one fought back to defeat Alexander Zverev 4-6 6-2 6-4 4-6 6-2 Friday in the US Open semi-finals to put himself on the brink of history. 

Djokovic will face second seed Daniil Medvedev in Sunday's final as he attempts to win a record 21st grand slam title and become the first man since Rod Laver in 1969 to win all four majors in a calendar year. 

Laver was in attendance at Arthur Ashe Stadium to watch the top seed exert his will as he has done in so many five-setters over the years, breaking down the younger player over the course of the match to emerge with yet another triumph. 

Zverev had ended Djokovic's chances of a Golden Slam with a semi-final win at the Tokyo Olympics, rallying for a three-set win after dropping the opening set, but the script was different Friday. 

It started with Djokovic losing the opening set for the fourth successive match in New York. In the previous three rounds, he did not drop more than three games in any subsequent set, but Zverev made him work harder this time. 

With the first set even at 4-4, Djokovic fell behind 15-40 and double faulted on break point to give Zverev the opening he needed. Though his next service game was a bit shaky, Zverev managed to take the set when Djokovic mis-hit a forehand.

The German's momentum did not last, though, as he returned the favour by double faulting on break point in his first service game of the second set and watched Djokovic level the match with relative ease. 

Zverev had a chance to take control early in the third, earning two break points at 2-2, but he failed to convert and did not get another chance. When Djokovic had a similar opportunity up 5-4, though, he closed it out.

Down 0-40 in that game, Zverev saved two break points – the latter via an epic 53-shot rally that was the longest at this year's US Open – but Djokovic slammed home an overhead winner on the next point to take the set. 

Zverev shook off that disappointment and put the pressure back on Djokovic by hammering a forehand winner down the line to break the top seed and take a 2-1 lead in the fourth.

The German did not falter the rest of the set, eventually serving it out to force a decider and push Djokovic to a fifth set for the first time since the French Open final against Stefanos Tsitsipas. 

Djokovic jumped to an early lead in the fifth, forcing Zverev to the net on break point in the second game with a beautiful drop shot before finishing the younger player off with a cross-court winner. 

Djokovic reeled off four consecutive points to break Zverev in his next service game, then held at love to put the fourth seed on the brink at 5-0. 

Zverev, a winner in seven of his previous eight five-setters, did not surrender, breaking Djokovic thanks to a double fault on game point to pull within 5-2. 

But Djokovic ended it there, breaking back to close out the match in the next game as Zverev sent a forehand into the net from the baseline.

DATA SLAM

With the victory, Djokovic improved to 34-2 in night matches at Arthur Ashe Stadium and 36-10 in five-set matches in his career, winning his last seven in a row.

Novak Djokovic knows he faces a tough challenge in his US Open semi-final with Alexander Zverev after coming from a set down to beat Matteo Berrettini.

The Serbian triumphed 5-7 6-2 6-2 6-3 to thwart Berrettini's revenge mission, having defeated the Italian in this year's Wimbledon final.

The world number one now faces the man who denied him a shot at the Golden Slam, with Zverev dumping Djokovic out of the semi-finals at Tokyo 2020.

And the 20-time grand slam winner was full of praise for his next opponent.

"He's in tremendous form, he's been winning a lot," said Djokovic, who still has the Calendar Grand Slam in his sights. "He has comfortably moved to the semi-finals here.

"I know his game well, we played in Tokyo. He's one of the best players in the world, but the bigger the challenge the more glory in overcoming it."

Reflecting on his victory over Berrettini, Djokovic felt he found his best form after dropping the opening set.

"This was a great match, with a lot of energy on and off the court," he said. 

"Matteo is a terrific player and every time we face each other it's a close battle.

"When I lost the first set, I managed to forget about it and move on. I was locked in at the start of the second and it was the best three sets I've played so far."

Novak Djokovic moved within two wins of an historic calendar Grand Slam at the US Open after completing a merciless comeback against Matteo Berrettini 5-7 6-2 6-2 6-3 en route to the semi-finals.

Berrettini was seeking revenge for his Wimbledon final loss to Djokovic and the Italian sixth seed gave himself a good chance after winning the opening set at Flushing Meadows on Wednesday.

But Berrettini was helplessly outclassed in a devastating display from world number one Djokovic, who is bidding to become just the third man to sweep all four majors in a year and first since 1969.

The 20-time major champion, who can also break the record for most men's slam titles – currently tied with Rafael Nadal and Roger Federer, will face Alexander Zverev in the New York semis.

For the third consecutive match, Djokovic done it the hard way, rallying after dropping the opening set, just like he did against Jenson Brooksby and Kei Nishikori.

In a brutal display of big hitting, Berrettini had the crowd roaring – firing down seven aces and saving two break points in a marathon first set lasting one hour, 17 minutes.

Berrettini held serve in a physically demanding sixth game after 12 minutes and seven deuces.

Djokovic – not without his chances – did not look like his usual self, spraying a forehand wide as Berrettini seized control following four set points.

Berrettini was looking to claim his first win over Djokovic after three consecutive defeats and earn his first top-10 victory at a grand slam (0-5 heading into the contest), but the Serb star turned the match on its head into the second set.

Djokovic, though, flipped the switch as he broke for the first time to move 3-1 ahead before consolidating for a 4-1 lead, silencing the pro-Berrettini crowd in New York, where the latter was unable to stop the rot.

Berrettini looked deflated and tired in the third set – Djokovic racing out to a commanding 3-0 advantage.

Djokovic missed the chance to move 5-2 ahead but it only delayed the inevitable as he fended off a break point the very next game to eventually earn a two-sets-to-one lead.

And the 34-year-old could not be stopped as he celebrated his 80th US Open match win in emphatic fashion.

 

Data slam: Can Djokovic be stopped?

Djokovic extended his winning streak at grand slams to 26 matches, while he also remains unbeaten in US Open quarter-finals (12-0). The record-chasing star also owns a 9-0 major record in 2021 after dropping the first set.

Alexander Zverev is riding a wave at the US Open after his confidence-boosting win over world number one Novak Djokovic en route to claiming gold at the Olympic Games.

Zverev survived a first-set scare to power past Lloyd Harris 7-6 (8-6) 6-3 6-4 in Wednesday's US Open quarter-final.

The German fourth seed will face either Djokovic, who is bidding to become just the third man to complete a calendar Grand Slam and first since 1969, or Matteo Berrettini for a spot in the men's final at Flushing Meadows.

Zverev – last year's US Open runner-up – said he has been fuelled by his semi-final win over Djokovic at the Tokyo Games.

"It's the biggest tournament in the world, Tokyo. It's the Olympics," Zverev said during his post-match news conference.

"Winning there against the world number one, especially that I was down a set and a break, being kind of out of the match, then coming back, it was different than the other matches. The emotions were different.

"Also securing a medal for Germany was very special to me. This year it seems like nobody can beat him in a big match, nobody can beat him at the grand slams.

"I feel like I was the first player to beat him in a very big match this year. That does give you something. To any person it would give you something.

"As I said before also, I think it was very important for me to back it up in the finals, back it up in Cincinnati. Hopefully I can continue this streak."

Zverev is in the midst of a career-best 16-match winning streak and has clinched 37 of 40 sets on the hard courts after winning Olympic gold and his fifth career ATP Masters 1000 crown in Cincinnati.

The 24-year-old is bidding to become the second man in history to win Olympic gold medal and the US Open/US Championships title in the same season, after Andy Murray in 2012.

On preparing against Djokovic, Zverev added: "You have to be perfect, otherwise you will not win.

"Most of the time you can't be perfect. That's why most of the time people lose to him. Against him, you have to win the match yourself. You have to be the one that is dominating the points. You have to do it with very little unforced errors.

"He is the best player in the world. He is very difficult to beat. But he's still also got to win tonight. He's playing Matteo Berrettini who is in very good form, finals of Wimbledon. I think he's looking forward to that match, as well. It's going to be an interesting match to watch those two."

Second seed Daniil Medvedev refuses to start thinking about a US Open final against Novak Djokovic despite reaching his third straight semi-final at Flushing Meadows on Tuesday.

Medvedev dropped a set for the first time at this year's US Open but still got through, winning 6-3 6-0 4-6 7-5 over Dutch qualifier Botic van de Zandschulp on Tuesday.

The 25-year-old will play the winner of the quarter-final between Canadian 12th seed Felix Auger-Aliassime and Spanish teenager Carlos Alcaraz in the last four.

Top seed Djokovic, who has won all three majors this year, looms on the other side of the draw, with a quarter-final match-up on Wednesday against sixth seed Matteo Berrettini, while fourth seed Alexander Zverev is still alive.

"I don't think about him [Djokovic], because as we saw, anybody can beat anybody," Medvedev said at his post-match news conference.

"If he's in the final, and if I'm there, I'm happy. He plays on the days where I don't play so I watch his matches just because I enjoy watching tennis.

"I'm not going to root or cheer for somebody. I'm just gonna enjoy the tennis and then prepare for the winner. It's same every match."

Medvedev's victory clinches his spot in the final four at Flushing Meadows for the third straight year, having lost the 2019 final to Rafael Nadal.

"[I'm] really happy to be in the semis again, third time in a row," Medvedev said. "I couldn't dream of it four years ago, but now it's three."

Medvedev will be several years older than his next opponent, with Auger-Aliassime turning 21 last month and Alcaraz is still only 18.

Neither has ever reached a major semi-final either, while Medvedev will be playing in his fourth, having won two of them previously including at this year's Australian Open.

"I always said that experience helps me," Medvedev said. "You never know, because you're gonna play tough opponents, semis or final.

"Who knows? Maybe Novak. But first of course Felix or Carlos. Whoever wins gonna be on huge fire. You know they are much younger than even me.

"But for them it's going to be a first semis of a slam. Experience is not everything, because, for example, when I was in my first semis of a slam, I won it. Doesn't mean if you're there for the first time you're gonna lose it. But I like that I have this experience."
