Frances Tiafoe will face Taylor Fritz in the semi-final of the US Open, where there will be an American in the men's final for the first time in 18 years.

After Fritz overcame Alexander Zverev, Tiafoe faced Grigor Dimitrov in a bid to tee-up an all-American semi-final in New York.

And Tiafoe was 2-1 up in sets and 4-1 up in the fourth when Dimitrov was forced to retire due to injury.

That means there is guaranteed to be an American in the final at Flushing Meadows for the first time since Andy Roddick faced Roger Federer in 2006.

"I didn't want to end it like that, for me or the crowd. But Friday is going to be one hell of a day," said Tiafoe.

"It's the biggest match of mine and Taylor's life.

"Obviously, it's not the way I wanted to get through but being in another semi-final here is incredible."

Data Debrief: Fortunate sons

This is the first time two Americans have reached, and will face each other, in the last four of a grand slam since Andre Agassi went up against Robby Ginepri in 2005, at Flushing Meadows.

Indeed, the United States has not had a men's singles major champion since Roddick triumphed at the US Open in 2003.

Aryna Sabalenka quipped the drinks would be on her to get the Flushing Meadows crowd onside for her US Open semi-final against Emma Navarro.

Home favourite Navarro will go up against a player in form in the last four, after last year's runner-up Sabalenka put on a show of force against Olympic champion Qinwen Zheng in the quarters.

Sabalenka claimed a statement 6-1 6-2 victory on Tuesday, in what was a rematch of this year's Australian Open final, which the Belarusian also won.

There was little let up for Zheng, as Sabalenka conceded fewer than five games against a WTA top-10 opponent for only the third time in her career, after wins over Coco Gauff in Indian Wells and Maria Sakkari at the WTA Finals last year.

Though Sabalenka knows that American Navarro, who followed up her win over defending champion Gauff by beating Paula Badosa, will have the crowd on her side.

"OK guys, drinks on me - and please give me some support in the next match," she laughed.

"She [Navarro] is a really good player. We had two battles, they were really close."

Sabalenka had more than just nerves to deal with against Zheng, given the great Roger Federer was watching on from the stands,

"I saw him there, saw him on the big screen," Sabalenka said regarding Federer, a five-time US Open champion.

"I was like, OK, I have to play my best tennis so he enjoys it. I have to show my skills, you know, slice skills, come to the net and all that stuff."

Data Debrief: Four on the spin for Sabalenka

Sabalenka has now reached four successive US Open semi-finals, as she takes her tally of last four appearances at grand slams to nine.

At the age of 26, she is the youngest woman to reach four straight semi-finals at Flushing Meadows since 2002.

She is the also first player to reach the women's singles semis at both the Australian Open and US Open in back-to-back years since Serena Williams (2015-16).

Home hopeful Taylor Fritz reached his first ever grand slam semi-final at the US Open, beating world number four Alexander Zverev in four sets at Flushing Meadows. 

Fritz, who had lost his previous four grand slam quarter-finals, came through tie-breaks in the first and fourth set to emerge a 7-6 (7-2) 3-6 6-4 7-6 (7-3) victor.

Both players traded blows in the opening set, with Fritz squandering the opportunity to take the opener in the 12th game after missing three set points, only to go on and win the tie-break. 

Zverev continued to match his American opponent stride for stride, but struck the decisive blow in the second set with a break point in the eighth game to level the encounter.

But backed by a raucous crowd inside Flushing Meadows, Fritz raced into a 3-0 lead in the third and despite Zverev finding a break of his own, he was unable to stop the world number 12 going within touching distance of victory. 

With the atmosphere intensifying, a second tie-break of the game would decide whether the encounter went the distance, with Zverev pulling the final ball wide to claim a famous win for Fritz at the Arthur Ashe Stadium.

Fritz could play fellow American Frances Tiafoe for a place in a first grand slam final, with Tiafoe squaring off against Grigor Dimitrov in Tuesday's night session.

Defeating Zverev at the age of 26y 310d, Fritz has become the oldest American in the Open Era to reach their maiden men's singles SF at the US Open.

It was the 12th-seeded Fritz's fourth win over an ATP top-10 player in a major this season, the most by an American man in one year since Andre Agassi had five in 1999.

Emma Navarro is ready for the challenge of either Aryna Sabalenka or Zheng Qinwen as she bids for US Open glory at Flushing Meadows. 

Navarro, who had never made it past the first round in her previous appearances at New York, put on an impressive display to win in straight sets against Paula Badosa.

The American found herself 5-1 down in the second set, only to win the next six games in a row to reach her maiden grand slam semi-final. 

She also became the second American player since 2000 to make their first grand slam women's singles semi-final at the US Open, after Jennifer Brady did so in 2020. 

But waiting in the next round is last year's runner-up, Sabalenka, or the recently crowned Olympic champion Zheng, a challenge Navarro is not shying away from.

"I've played both of them a couple of times,” said Navarro. “They are great players, I think we will have a great battle. But I'll be up for the challenge of either of them.

"Both big servers, big hitters and I think they will come aggressively at me whichever one it is - but yeah I'll be ready."

Navarro had only won one match at the main stage of a grand slam before this year, but has got better and better throughout her breakout year of 2024.

She reached the third round of the Australian Open, the last 16 at the French Open, the quarter-finals at Wimbledon and now the semi-finals of her home slam.

"After I got it back to 5-2, I had a bit of an inkling that it might be two sets," added Navarro.

"I just wanted to stay really tough and stick in there and even if I did lose the second set, I wanted to set the tone for the third set.

"Just really happy with my performance today. Crazy to be moving on to the semi-finals. US Open baby."

Aryna Sabalenka continued her quest for US Open redemption as she reached another quarter-final at Flushing Meadows with a straight-sets victory over Elise Mertens.

A year after her defeat to Coco Gauff in the showpiece match of the competition, Sabalenka watched on as the defending champion exited the competition following defeat to Emma Navarro before she took to the court. 

But the Belarusian ensured there would be no upset on this occasion, needing an hour and 36 minutes to win 6-2 6-4 as she progressed to her fourth consecutive quarter-final at the tournament.

On her way to victory, Sabalenka struck 41 winners compared to her Belgian opponents' 14, and said she is relishing the opportunity of playing in New York this time around.

"I really enjoy playing here,” Sabalenka said. “The crowd are amazing. I really enjoy playing on these big stadium and feel all the support.

“I just don’t want to leave early here. I just want to stay as long as I can and enjoy this beautiful court.

“I think that’s why I’m consistently here.”

Sabalenka will face China's Olympic champion Zheng Qinwen, who beat silver medallist Donna Vekic 7-6 (7-2) 4-6 6-2, in the last eight in what is a repeat of their Australian Open final earlier this year.

Data Debrief: Sabalenka, queen of Flushing Meadows

Sabalenka has claimed her 25th women's singles match win at the US Open. Since 2000, only Kim Clijsters (30) has managed 25 wins at the event in fewer matches than the Belarusian (31).

She has now reached a 10th career women's singles quarter-final at grand slam events. Since the start of the 2020 season, Sabalenka has also become the first player to reach 10 or more women's singles quarter-finals.

Sabalenka also reached a fourth consecutive women’s singles quarter-final at the US Open, becoming the first player to achieve the feat since Serena Williams, who made six straight quarter-finals between 2011 and 2016.

Defenidng US Open champion Coco Gauff was dumped out of the competition on Sunday, blaming a lack of execution in her defeat to fellow American Emma Navarro.

Gauff, who was also comfortably beaten by Navarro at Wimbledon two months ago, fell to a 3-6 6-4 3-6 loss after serving 19 double faults at the Arthur Ashe Stadium.

A bright start from Navarro saw earn a first break in the opening game after two double faults by Gauff in a sign of things to come for the world number three.

Despite a comeback in the second set, Gauff's remaining service games were punctuated by more errors in the third, serving 11 of her total double faults in the final set to hand Navarro the victory. 

"I fought really hard today. I just didn't take care of my serve, so that was the biggest difference," Gauff said.

"Mentally and emotionally I gave it my all. Of course, there were things execution-wise, where I wish I could serve better.

"I think if I would did that, it would have been a different story for me in the match."

Navarro will go on to play 26th seed Paula Badosa in the last eight after the Spaniard thrashed China’s Wang Yafan 6-1 6-2 earlier on Sunday.

Data Debrief: Doubles troubles for Gauff

With 19 double faults, Gauff served the equal-most double faults for her career in a single WTA main draw match, serving as many against Martina Trevisan at Roland Garros in 2020.

Navarro is the first American player to defeat the women’s singles defending champion at the US Open since Serena Williams in 2002 against Venus Williams in the final.

She is also now the player with the most hard court WTA quarter-finals in 2024 (seven, surpassing Elena Rybakina).

Aryna Sabalenka came from a set down to keep her US Open dream alive as she beat Ekaterina Alexandrova in the early hours at Flushing Meadows. 

Sabalenka emerged on court at the Arthur Ashe Stadium at seven minutes past midnight following Novak Djokovic's shock exit from the tournament, and consecutive upsets looked to be on the cards. 

However, the Belarusian responded from a disappointing opening set as she looks to avenge her defeat in the showpiece match against Coco Gauff a year ago.

The world number two set up a meeting with Belgium's Elise Mertens as she emerged a 2-6 6-1 6-2 victor in one hour and 40 minutes in New York. 

"I don't know what I did, I was just trying to stay low, put as many balls as I can back on that side," Sabalenka said. 

"She played incredible tennis in the first set. It was really tough to change it."

"I'm really happy I was able to turn around this match and get this really difficult win. Thanks so much for staying that late."

Data Debrief: Sabalenka survives late, late show

Sabalenka's encounter with Alexandrova was the latest starting match at the US Open, beating Gabriela Sabatini and Beverley Bowes' meeting in 1987 that started at midnight.

The Belarusian, however, will be hoping for a much improved performance in the next round, having produced 27 unforced errors throughout the contest and serving four double faults.

Defending US Open champion Novak Djokovic suffered a shock exit at Flushing Meadows as he lost in four sets to Alexei Popyrin. 

Djokovic arrived at the tournament with confidence following his gold medal triumph at the Paris Olympics, and was tipped to lift a record-extending 25th grand slam title.

However, the Serbian's hopes of a fifth success in New York were dashed as he followed fellow favourite Carlos Alcaraz out of the competition in the third round. 

Popyrin emerged victorious in three hours and 18 minutes, prevailing 6-4 6-4 2-6 6-4 to confirm Djokovic's earliest exit from the tournament in 18 years.

"I have played some of the worst tennis I have ever played," Djokovic said.

"Honestly, the way I felt and the way I played from the beginning of this tournament, third round is a success."

"I tried my best, I didn't have any physical issues. I just felt out of gas, and you could see that. From the first match, I just didn't find myself on this court.

"Life moves on. I'll try to recalibrate and look forward to what's next."

Data Debrief: Another one bites the dust

Djokovic was far from his clinical best, serving a career-high 14 double faults in a grand slam match and committing 49 unforced errors.

The Serbian will also end the year without winning a grand slam title, the first time he has done so since 2017.

But the day belonged to Popyrin, saving 12 of the 16 break points he faced against the world number two, finding particular success with his forehand as 31 of his 49 winners came from that shot.

Naomi Osaka's wait for a deep run into a grand slam rolls on after the former world number one was beaten by Karolina Muchova at the US Open.

Osaka, a two-time champion at Flushing Meadows, lost 6-3 7-6 (7-5) on Thursday.

She came up against a player in fine form in Muchova, with the Czech displaying the quality that saw her reach the semi-finals a year ago.

"I was just really trying to be focused," Muchova said.

"I know she's an amazing player and that I have to bring the A-game to have a chance. So I was just trying to be really focused on myself. I knew I had to serve well because her serve is really good. So I was just trying to be kind of locked in myself and focused out there."

"Then the energy and the big court and all that, it for sure helps me. I like that."

Osaka, meanwhile, suggested the nerves got to her on Arthur Ashe Stadium.

"I think during the pressure moments I got nervous," Osaka said, and I don't know if I just have to keep playing more matches and get used to that feeling, especially on a really big stage.

"Honestly, if I get past the disappointment, I feel pretty proud of myself to have gotten that many opportunities while still feeling like I could have played much better."

Data Debrief: Fifth time's the charm?

Muchova is one of nine players to have defeated five former world number ones at grand slam events.

However, out of those, she is the only active player yet to win a major or a WTA 1000 title. Will that change in New York?

Carlos Alcaraz suffered a shock defeat to Botic Van de Zandschulp at the US Open.

Alcaraz, the French Open and Wimbledon champion, had been tipped to win a third major of the year at Flushing Meadows.

However, the Spaniard's hopes of becoming just the third player to win the French Open, Wimbledon and US Open in the same season were dashed by unseeded Dutchman Van de Zandschulp in the second round.

Van de Zandschulp prevailed 6-1 7-5 6-4 to cause the tournament's first huge shock.

"I think my level stayed at the same point all the match," said Alcaraz, who had won his previous 15 grand slam matches.

"It wasn't enough to win the match or to give myself the chance to get into the match or try to give myself chances.

"I didn't feel well hitting the ball. I think I made a lot of mistakes. When I wanted to come back, it was too late.

"He didn't make a lot of mistakes that I thought he was going to do so I was confused a little bit. I didn't know how to manage that.

"I came here with not as much energy as I thought that I was going to come with. But I don't want to put that as an excuse."

Data Debrief: Dutch delight

This was Van de Zandschulp's second career win over a top-five opponent, as he became just the second Dutch player to achieve that feat at the US Open, while he is the first from his nation to defeat a top-three player since 1991. 

Indeed, Van de Zandschulp, who will face Jack Draper next, snapped a 43-match losing streak for Dutch players against ATP top 10 opponents at the majors.

Iga Swiatek cruised into the third round of the US Open with a commanding straight sets win over Ena Shibahara in 64 minutes at Flushing Meadows. 

Swiatek, who won the title in New York in 2022, made just six unforced errors as she triumphed 6-0 6-1 against her Japanese opponent. 

A dominant opening service game set the tone for the encounter, with the world number one racing into a 4-0 lead in double quick time before closing out the first set. 

Shibahara, however, would get her first and only game on the board early in the second, but had to do so by saving three break points to hold her serve. 

From then on, Swiatek took control, dropping just four points in the final three games to comfortably progress to the next round without breaking a sweat.

Swiatek will face the winner of Elisabetta Cocciaretto and Anastasia Pavlyuchenkova's encounter for a place in the quarter-finals of the competition on Saturday.

Data Debrief: Super Swiatek rolls on

Swiatek is the fifth player in the Open Era to reach the round of 32 in 19 consecutive women’s singles grand slam tournaments, after Martina Navratilova, Steffi Graf, Arantxa Sanchez Vicario and Conchita Martinez.

The Pole is also the youngest player to win 20 of her first 22 second round appearances in women’s singles grand slam since Victoria Azarenka in 2012, who won 21 of her first 22 second round appearances.
