Djokovic sets up US Open semi-final showdown with Alcaraz

Novak Djokovic crushed the hopes of American Taylor Fritz to stay on course for a record-breaking 25th Grand Slam at the US Open on Tuesday night.

Djokovic reasserted his dominance over fourth seed Fritz with a 6-3 7-5 3-6 6-4 victory to set up a blockbuster semi-final showdown against Carlos Alcaraz.

The 38-year-old arrived at Arthur Ashe Stadium having beaten Fritz in all 10 of their previous meetings but was breathing heavily at times to move past last year's runner-up on Arthur Ashe Stadium.

Djokovic will now play in his fourth Grand Slam semi-final of the season - marking the seventh time in his career that he has achieved that feat - against in-form Spaniard Alcaraz, who hasn't dropped a set all tournament and was a comfortable winner against Czech Jiri Lehecka earlier in the day.

Sabalenka to face Pegula after walkover

Defending champion Aryna Sabalenka was given a free passage through to the US Open semi-finals after Marketa Vondrousova withdrew through injury.

Less than two hours before they were supposed to meet in the night session on Arthur Ashe Stadium, the tournament announced Vondrousova was not able to take to the court.

The Czech's withdrawal means there will be a rematch of last year's final in the last four, with Sabalenka taking on fourth seed Jessica Pegula.

It is a bitter blow for former Wimbledon champion Vondrousova, who has struggled with injury throughout her career but had been on a great run in New York after beating Jasmine Paolini and Elena Rybakina.

In a statement via the organisers, the 26-year-old Czech said: "I am sorry to announce that I have to withdraw from my quarterfinal match this evening due to a knee injury.

"I tried my best to take the court today but during the warm-up I felt again my knee and after consultation with the tournament doctor decided not to risk aggravating the injury.

"I appreciate all the support this tournament and apologize to the fans who were looking forward to the match. I had an amazing time here in NY and can't wait to be back next year."

Writing on Instagram, Sabalenka said: "So sorry for Marketa after all she's been through. She has been playing amazing tennis and I know how badly this must hurt for her. Take care of yourself and I hope you can recover quickly. Love Aryna."

Earlier, Pegula made it back to the semi-finals in convincing fashion by beating another Czech former Wimbledon champion, Barbora Krejcikova, 6-3 6-3.

Venus' dream US Open run comes to an end

The dream doubles run of 45-year-old Venus Williams came to an end as she and partner Leylah Fernandez were dispatched 6-1 6-2 by top seeds Katerina Siniakova and Taylor Townsend in the quarter-finals.

Williams was aiming to win her first Grand Slam title since 2017 and her third women's US doubles title.

The 14-time women's doubles Grand Slam champion, playing in her 25th US Open, won the first of her two titles in New York with sister Serena in 1999, three years before Fernandez was born.

Siniakova and Townsend, bidding to claim their third Grand Slam title as a pair, will face No 4 seeds Elise Mertens and Veronika Kudermetova in the semi-finals.

"What I'm proudest of is it's not easy to come off the bench. It really isn't, and I have never had a layoff that long. It brought new challenges that I wasn't ready for in so many ways. So I'm very proud that I stayed myself. I didn't try to play another game. I didn't try to play it safe. I went for it, and that's who I am. I go for it. When you go for it, good things happen," Williams said. "Perhaps I didn't get there this time, but I know who I am, and I know that I can work once I have a little chance."

On her future plans, Williams said: "I haven't given that any thought. I do have commitments, places I said I'd be, people expecting me to be there the next few weeks. So I have to go and show up.

"If there is opportunity for me to play, then hopefully I can get back somewhere this year. I just don't know. I really don't."
