Frances Tiafoe is looking to book his spot in a second US Open semi-final as the American takes on Grigor Dimitrov for a place in the final four.

Two years on from making his deepest run at a grand slam on home soil, Tiafoe has again looked in good form on the New York hard courts, surviving a five-set thriller against good friend Ben Shelton before beating Alexei Popyrin, conqueror of Novak Djokovic, to reach this stage. It is now 21 years since Andy Roddick became the last American man to taste success at Flushing Meadows, and Tiafoe will hope to end that drought.

But he faces a vastly experienced last-eight opponent in the classy Dimitrov, back to somewhere near his best in the last 12 months. The Bulgarian has returned to the top ten in the world rankings after a 2024 that has included an appearance in the final of the Miami Open, and he holds a head-to-head advantage over his opponent, winning three of four meetings between the pair.

In a week of unusually late starts, Tiafoe and Dimitrov took the court before 9pm.

The young American won the first set 6-3, lost the second set after a nail-biting tiebreak 7-6, and then clinched the third set 6-3.

Both men have made eight unforced errors in the third set — but Dimitrov has made twice as many forced errors, perhaps explaining why he currently trails the American.

Tiafoe is up 5-3 in the third set after a nail-biting tiebreak in the second set, which Dimitrov won.

For his part, however, the Bulgarian has hit five winners this set compared to Tiafoe’s one.

The men are tied in sets, but Tiafoe looks like he’s about to clinch the third.

04:21 , Jonathan Veal

Taylor Fritz has ended his quarter-final hoodoo by reaching the last four of the US Open.

The 26-year-old American had lost all of his previous four last-eight matches at a grand slam but put that right on home soil by beating Alexander Zverev 7-6 (2) 3-6 6-4 7-6 (3) on Arthur Ashe.

Fritz is flying the flag for the United States and has his eyes set on becoming the first men’s home champion in New York since Andy Roddick 21 years ago.

Dimitrov came back in the second set, eeking out a win 7-6, after losing the first set 6-3.

Tiafoe came off of the first set as a powerful force, pushing the Bulgarian from one direction to the next, and hitting winners left and right.

But Dimitrov turned it around, reducing the number of unforced errors and leaning into his strategy.

ICYMI: Sabalenka inches closer to third grand slam win at US Open

04:00 , Jonathan Veal

Aryna Sabalenka has moved even closer to her first US Open title after breezing into the semi-final.

The world number two, who was beaten at Flushing Meadows last year by Coco Gauff, proved to be too much for Olympic champion Qinwen Zheng to handle in a repeat of the Australian Open final in Melbourne.

The Belarussian was victorious, getting the better of her Chinese opponent with a final score of 6-1 6-2.

Tiafoe wins first set

02:51 , Kelly Rissman

Tiafoe won the first set 6-3.

The 26-year0ol dhas shifted from playing on the defensive to dominating as the match goes on.

The American has pulled Dimitrov from one corner to the next, moving up to the net, and put away irretrievable shots.

His Bulgarian counterpart, however, has an impressive serving record. He leads the league in the number of first serve points won. While his overall average is 85% of first serves won, this game he has won 67%.

Tiafoe breaks Dimitrov

02:33 , Kelly Rissman

Tiafoe is on.

He broke Dimitrov, now leading 3-2 in the first set.

The 26-year-old has been playing offensively, often coming up to the net. In some cases, Dimitrov has predicted that Tiafoe was approaching, offering him a lob, but in others, Dimitrov has been forced to make risky shots down the line.

Dimitrov leads in first few games

02:16 , Kelly Rissman

Both men have won on their serves. The rallies haven’t been long, typically ending with one of them making an unforced error within the first few shots as they still seem to be warming up.

So far, Dimitrov appears to be one step ahead of the young American. He has been accurately anticipating when he will move in and where he will try to land a drop shot.

In a highlight moment, Tiafoe recovered from a wide shot to his backhand with lob. Dimitrov returned with an overhead slam to the American’s forehand for a winner.

Dimitrov is up two games to one in the first set.

Dimitrov takes the first game

02:03 , Kelly Rissman

Dimitrov started off strong. He opened with an ace on the first point. And another ace on the second.

The 33-year-old Bulgarian largely had Tiafoe on the defensive, taking the first game with a killer shot that hit the outside of the right singles line.

Frances Tiafoe and Grigor Dimitrov are about to face off at Arthur Ashe Stadium.

The player who wins will face American Taylor Fritz, the number 12 seed, in the semis.

Sabalenka wins in two quick sets

01:35 , Kelly Rissman

Sabalenka defeated Zheng 6-1, 6-1.

“She is playing such incredible tennis and it was tough facing her,” the Belarusian star said after her victory about Zheng.

She is heading for the semifinals where she will face American player Emma Navarro.

When asked what to do to get New Yorkers to support her in the semis, she joked: “Drinks on me!”

Sabalenka is a force to be reckoned with in the quarters

01:19 , Kelly Rissman

Sabalenka has been dominating from the baseline, hitting with a power that has gone unreciprocated by Zheng.

The number 7 seed, meanwhile, has not only been forced to play defense but also has struggled with her first serve.

The Belarusian player is now ahead by one set and currently up by 4 games to 1 in the second.

Nick Kyrgios makes open offer to coach Coco Gauff after US Open heartbreak

01:15 , Kelly Rissman

Coco Gauff was beaten by fellow American Emma Navarro in the fourth round of her US Open title defence as she struggled with many aspects of her game.

On that particular occasion, Gauff’s forehand struggled, but her serve completely let her down. She served 19 double faults, and 11 in the final set to cap off a difficult summer, where she has lost in the last 16 of the last three major tournaments.

Since the defeat, there have been calls for Gauff to replace her coach Brad Gilbert and look elsewhere – and there has been an unlikely offer from Nick Kyrgios.

Meanwhile, another quarterfinals match is underway.

Belarusian star Sabalenka, the number 2 seed,  is playing Zheng, who made history when she won a gold medal at the Olympics in Paris this summer. She became the first Asian tennis player to win an Olympic gold in singles.

Sabalenka cleaned up the first set, 6 games to 1.

The 22-year-old destroyed Czech Tomas Machac in the fourth round to become the first British male quarter-finalist in New York since Andy Murray in 2016.
