He managed a break for Dimitrov and was now leading the first set 3-2.

The 26-year-old played offensively and often got to the goal. In some cases, Dimitrov anticipated Tiafoe’s approach and offered him a lob, but in other cases, Dimitrov was forced to take risky shots along the line.

Both men won on serve. The rallies didn’t last long and usually ended with one of them making an unforced error on the first few shots as they appeared to be still warming up.

So far, Dimitrov seems to be one step ahead of the young American, having accurately predicted when the latter will strike and where he will try to land a drop shot.

In a moment of glory, Tiafoe recovered from a long shot to his backhand with a lob. Dimitrov countered with an overhead slam to the American’s forehand and scored the winner.

Dimitrov is ahead in the first set by two games to one.

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

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

The 26-year-old American will serve as the next…

Frances Tiafoe and Grigor Dimitrov face each other at Arthur Ashe Stadium.

The winner will face American Taylor Fritz, seeded 12th, in the semifinals.

Sabalenka defeated Zheng 6:1, 6:1.

“She plays such incredible tennis and it was tough to compete against her,” said the Belarusian star after her victory over Zheng.

She is aiming for the semifinals, where she will face American Emma Navarro.

When asked what she could do to get New Yorkers to support her in the semi-finals, she joked: “The drinks are on me!”

Sabalenka dominated from the baseline, striking with a power that Zheng could not reciprocate.

Meanwhile, the No. 7 seed was not only forced to play defensively and was pulled from one side of the court to the other, she also had problems with her first serve.

The Belarusian player is now one set ahead and currently has a 4-1 lead in the second set.

On this particular occasion, Gauff struggled with her forehand, but her serve also failed her completely. She made 19 double faults and 11 in the final set, capping a difficult summer in which she lost the round of 16 in the last three major tournaments.

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

Meanwhile, another quarter-final match is already underway.

Belarusian star Sabalenka, the No. 2 seed, will play against Zheng, who made history this summer at the Paris Olympics when she won a gold medal, becoming the first Asian tennis player to win Olympic singles gold.

Sabalenka won the first set 6:1.

Jack Draper is “incredibly proud” to have reached the first Grand Slam quarterfinals of his career at the US Open – a feat he achieved in front of Vogue editor Anna Wintour 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 reach the quarterfinals here since he did it in 2016 is a huge achievement for me,” he said after a 6-3, 6-1, 6-2 win. “I’m really, really proud of this achievement and hope I can do even more.”
