Tiafoe vs Dimitrov as it happened: US Open result and final score

Jessica Pegula says she is not feeling the same pressure as she aims to end her grand slam quarter-final hoodoo.

The American made it through to her seventh career last-eight tie at a grand slam after she beat Diana Shnaider in the fourth round of the US Open.

The previous six matches all ended in defeat, but Pegula has a different outlook heading into a tie with world number one Iga Swiatek tomorrow.

In a battle of New York-born baseliners, Navarro, who beat defending champion Coco Gauff in the previous round, stunned Badosa by winning the final six games of the second set to wrap up victory in 72 minutes.

Jack Draper is “incredibly proud” of reaching his first career grand slam quarter-final at the US Open – a feat pulled off with Vogue editor Anna Wintour watching in his box.

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.

“To follow in Andy’s footsteps and make the quarter-finals here since he did it in 2016, it’s a big achievement for me,” he said after a 6-3, 6-1, 6-2 win. “I’m really, really proud of that achievement and hopefully I can do more.”

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.

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.

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, being pulled from one side of the court to the other, 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.

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!”

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.
