Hubert Hurkacz's fine season continued as he ended Andy Murray's run at the Moselle Open on Friday.

Top seed Hurkacz beat Daniil Medvedev and Roger Federer on the way to the semi-finals at Wimbledon, and previously beat Murray in Cincinnati.

Hurkacz is ranked 13th in the world and is pushing for a place at the ATP Tour Finals, and he edged closer to a fourth career title by defeating Murray again in Metz.

The 24-year-old prevailed 7-6 (7-4) 6-3 over the former world number one, who was playing in his first ATP Tour quarter-final of the year.

"Andy is an unbelievable competitor, he has achieved so much throughout his career," Hurkacz said. "He is coming back from a tough injury and playing at a very high level, so he is amazing and you can be inspired by his results."

Next up for Hurkacz is Peter Gojowczyk, who overcame Marcos Giron 3-6 6-1 6-3 and is backing up his recent US Open run in strong fashion.

The other last-four match will take place between French home favourite and third seed Gael Monfils, who has reached his first tour semi-final since February last year, and Pablo Carreno Busta.

Carreno Busta, the Spanish second seed, needed three sets to beat Holger Rune, while Monfils had an easier time of it against Nikoloz Basilashvili, winning 6-3 6-3.

At the Astana Open, second seed Alexander Bublik beat Carlos Taberner 6-3 6-4, as he hunts a first singles title.

A crowd favourite in Kazakhstan, whom he has represented since 2016, Russian-born Bublik faces a semi-final against Soonwoo Kwon, who got past Laslo Djere.

Fifth seed John Millman succumbed to fellow Australian James Duckworth, who will face Ilya Ivashka for a place in the final.

Top seed Aslan Karatsev exited the Astana Open at the last-16 stage with a straight-sets defeat to Emil Ruusuvuori on Thursday.

World number 84 Ruusuvuori saved a set point in the first-set tie-break on his way to a 7-6 (8-6) 6-4 victory and will now face Ilya Ivashka for a place in the semi-finals.

There was nearly another upset as home hopeful Alexander Bublik, seeded second, had to recover from a set down to overcome Miomir Kecmanovic 2-6 6-3 7-5.

Carlos Taberner awaits Bublik in the next round after the Spaniard beat Egor Gerasimov 5-7 7-6(5) 7-5.

Kwon Soon-woo and James Duckworth saw off Dusan Lajovic and Filip Krajinovic respectively in straight sets to remain a course for glory.

At the Moselle Open in Metz, meanwhile, Gael Monfils took out Philipp Kohlschreiber 7-6(2) 6-4 to reach the quarter-finals on home soil.

Tournament favourite Hubert Hurkacz made light work of 2016 champion Lucas Pouille with a 6-2 6-3 victory to set up a meeting with Andy Murray in the quarter-finals.

Elsewhere on Thursday, German qualifier Peter Gojowczyk proved too strong for Karen Khachanov and will now face Marcos Giron, who upset fourth seed Alex de Minaur.

Andy Murray battled through to the second round of the Moselle Open with a 4-6 6-3 6-2 victory over sixth seed Ugo Humbert on Tuesday.

Murray chose to play in the event as a wildcard to improve his world ranking and avoid tougher first-round encounters, such as facing Stefanos Tsitsipas at the U.S. Open, and he recovered from going behind in the opening set to ease through his first-round tie.

Humbert, who is ranked 26th in the world, came into the clash 87 places ahead of the two-time Wimbledon winner but failed to make home advantage count as the Scot dispatched of him in just over two hours.

Karen Khachanov, who is the seventh seed in Metz, avoided a similar first-set scare to overcome Alexandre Muller 4-6 6-1 6-3, while Marcos Giron edged past Arthur Rinderknech 3-6 7-6 (7-3) 6-4.

That win sets up a second-round tie with fourth seed Alex de Minaur, with Alejandro Davidovich Fokina sneaking past Gilles Simon 4-6 (4-7) 7-6 (7-2) 6-2 in Tuesday's other match.

Frenchman Benoit Paire crashed out of the Astana Open to world number 97 Egor Gerasimov as he lost 7-5 6-4.

John Millman, the fifth seed, did not endure similar struggles as he recovered from losing the first set to ease past Dmitry Popko 3-6 6-1 6-4.

Meanwhile, Ilya Ivashka coasted past Elias Ymer 6-2 6-4 in just over 90 minutes to secure his second-round berth in the Czech Republic.

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.

Lorenzo Sonego made an impressive start at the Moselle Open as the fifth seed defeated Marton Fucsovics in straight sets. 

The Italian recorded his 25th win of the year on the ATP Tour on Monday, winning 6-3 6-2 in 73 minutes while not even conceding a break point to Fucsovics. 

"I was really focused," said Sonego. "Marton is a great player and it was a tough match. I liked my tennis and I am really happy.  

"I am confident because this year has been my best. I am now number 24 in the world, which is my best ranking. I have played my best tennis this year." 

Vasek Pospisil also moved through, beating home wildcard hope Gregoire Barrere 6-3 6-4. 

Hubert Hurkacz is the top seed at the ATP 250 event in Metz, with Gael Monfils and Andy Murray among the other stars yet to play their first match. 

At the Astana Open, which has the same ranking points available, Miomir Kecmanovic was a 6-4 6-2 winner over Fernando Verdasco. 

Seventh seed Laslo Djere, meanwhile, had to battle hard to end a four-match losing streak on the ATP Tour. He edged into the last 16 with a gruelling 6-4 3-6 6-4 win over Colombia's Daniel Elahi Galan. 

The highest-ranked players in the tournament are Russian Aslan Karatsev and home hope Alexander Bublik. 

Second seed Bublik will start his campaign against Kecmanovic, whose victory over Verdasco was his first win since the Tokyo Olympics 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."

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."

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."

British tennis was on a super Saturday high at the US Open as Emma Raducanu took centre stage – after Joe Salisbury, Gordon Reid and Alfie Hewett celebrated title success.

Salisbury completed a remarkable doubles double, adding the mixed title to the men's crown he secured on Friday, and Reid and Hewett teamed up to clinch a calendar Grand Slam in wheelchair men's doubles.

After Salisbury and American partner Rajeev Ram won the men's doubles title by beating Jamie Murray and Bruno Soares, Salisbury returned on Saturday to land another title, the fourth major of his career.

Salisbury teamed up with another American partner, Desirae Krawczyk, to see off Mexican Giuliana Olmos and Salvadorean Marcelo Arevalo 7-5 6-2 on Arthur Ashe Stadium, in the match directly before the women's final.

Raducanu, the world number 150, was going for glory in the women's singles final against another unlikely finalist in Canada's Leylah Fernandez.

If she was seeking inspiration from fellow Britons, it was in plentiful supply, with wheelchair maestros Reid and Hewett scoring a 6-2 6-1 doubles victory over Japan's Shingo Kunieda and Argentina's Gustavo Fernandez.

That meant they sealed a clean sweep of the Australian Open, French Open, Wimbledon and the US Open in 2021, becoming the first men's wheelchair duo in history to perform that feat.

France's Stephane Houdet previously won a calendar Grand Slam in the event, but he played with two different partners during the 2014 campaign, landing three titles with Kunieda and one with Joachim Gerard.

Rafael Nadal posed with crutches and an apparently bandaged foot as the injured former US Open champion revealed on Saturday he has undergone treatment in Barcelona.

The 20-time grand slam winner announced in August that his season was over, as he battles a problem that has troubled him since 2005 and has recently hindered his tournament preparation.

Nadal felt he was unable to do himself justice, and since a French Open semi-final defeat to Novak Djokovic in June, he has played just two more matches, reaching the last 16 at the Citi Open in Washington.

He wrote on Instagram on Saturday: "Hello everyone, I have not communicated with you through the networks for some time.

"I can tell you that I was in Barcelona with my team and the medical team, to receive a treatment on my foot that will mean I take a few days of rest and a few weeks off court.

"I am back home and in the process of recovery. Thank you all for your support!"

The social media post shows Mallorca native Nadal giving a thumbs-up gesture to the camera, but it also gives an indication of the extent of his problem.

He stands with only his right foot on the ground, the left raised off the floor in what looks like an effort to protect it, as he props himself up with a pair of crutches in his left hand.

Nadal has won the US Open four times, most recently in 2019, but has been one of a number of star-name absentees from this year's tournament in New York.

The 35-year-old has 13 French Open wins among his haul of majors, and stands level on 20 grand slams with Roger Federer and Novak Djokovic.

Djokovic has an opportunity to go top of the all-time men's list on Sunday when he faces Daniil Medvedev in the men's final at Flushing Meadows.

As Nadal suffers, so does his great rival Federer. A Nadal return to action in 2022 appears a more likely prospect than another Federer comeback.

Federer has cast some doubt on whether he will play again, as the 40-year-old battles knee trouble. The Swiss said last month he would be "on crutches for many weeks" after surgery, declaring he wanted to give himself "a glimmer of hope" of featuring again on tour.

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.

The first time Daniil Medvedev made the US Open final, in 2019, he was just happy to be there, having made his deepest run at a grand slam. 

The Russian will enter Sunday's final at Flushing Meadows with a different mindset after breezing past Felix Auger-Aliassime 6-4 7-5 6-2 in the semi-finals. 

After falling to Rafael Nadal in five sets two years ago in New York and losing to Novak Djokovic in the Australian Open final earlier this year, Medvedev is ready for a grand slam title of his own. 

"The more you lose something, the more you want to win it," Medvedev said after his semi-final win Friday. 

"I lost two finals. I want to win the third one. That's tennis, we have two players, only one going to win. You never know what's going to happen, but I'm going to try more than I did the first two times."

Medvedev has rolled through the draw, dropping only one set on the way to the final – the third to Botic van de Zandschulp in the quarter-finals. 

The world number two hopes the fact that he has not faced any marathon matches during his run to the final will help him Sunday. 

"There were some tight moments. There were some tight battles," he said. "Against Botic I won 7-5 in the fourth, which is not that much of a margin.

"It's never easy, but I'm happy that I managed to save a lot of physical abilities, physical power, and mental power.

"For sure, I mean, I don't think anybody is capable of winning a slam after playing, let's say, first three rounds five sets. I doubt this ever happened. So this is important.

"I'm really happy I managed to make it kind of fast."

Friday's match was no different, as Medvedev's only difficulty came when he fell behind 5-2 in the second set. 

But Auger-Aliassime could not finish the job, with Medvedev reeling off five successive games to end the threat before closing out the Canadian with ease in the third. 

"Many times you're going to lose a break against such an opponent as Felix, he had set points on his serve, you're going to lose a set," Medvedev said. "We can never know now how the match would go. Could be completely different story, being one set all, would be the first time for me in the tournament.

"I'm happy I managed to save this game, doing one great point and second one making him play the volley. Then it turned the match around. I think he started doubting.

"For sure it stayed in his mind, this game, so he started missing. I started putting more pressure. The match turned around. That was the key point."
