US Open 2026: Katie Boulter blown away by Karolina Muchova

The British No 1 was broken in all seven of her service games in a chastening 6-1 6-0 defeat inside 58 minutes on Louis Armstrong Stadium.

Boulter traded breaks with Muchova at the start of the first set only for the 2026 Wimbledon finalist to pull clear and put on a clinic for her beleaguered opponent.

Boulter double faulted eight times and produced 22 unforced errors in a nightmare, error-strewn performance that left her hopes of progressing in tatters.

"It was a tough day at the office for Boulter, and that is where Muchova deserves so much credit. She is such an all-round player. The focus was definitely on Muchova rather than what Boulter didn't do.

"The highlight reel from the match was outstanding. There were so many incredible shots and great rallies. She's got the variation, using the little short chip cross-court, following the ball in and knocking off volleys at the net. She can do anything.

"She has reached the French Open and Wimbledon finals and is great on hard courts. If she can stay healthy, she has the experience, mentality, confidence and belief to win one of these tournaments one day."

"You've got to focus on the positives, and that was how well Muchova played.

"She showed us every trick in the book. She has so much in her repertoire. She's playing with a lot of confidence for something who hasn't played a lot since Wimbledon.

"Not a good day at the office for Boulter."

"Karolina Muchova has yet to win a Grand Slam in her career but played some exceptional tennis. On that evidence, she has brilliant potential in this tournament.

"A day to forget for Katie Boulter. She just wasn't there and lost her serve seven times out of seven. That does not give you a chance."

Choinski four-day first-round run brought to end

Britain's Jan Choinski made it to day four at the US Open, but was still a first-round casualty.

The towering German-born 30-year-old was beaten in straight sets by fellow beanpole, Dutchman Botic van de Zandschulp.

Getting to the first Wednesday at Flushing Meadows is usually a notable achievement for a British player.

But Choinski's stay at the tournament was only extended after his first-round match was pushed back by the rain in New York.

A handful of players were already through to round three by the time Choinski took to the court, but he was soundly beaten in the big-serving battle 6-3 6-1 7-6 (5) in just under two hours.

Choinski is coached by his girlfriend Sophia, who was shouting encouragement from his players' box.

He said: "She always tries to help me, tries to keep me positive, for sure.

"In the first set it was quite good, I had some chances but from that point it got tough.

"The guy was playing aggressively and she just keeps me fighting and motivated. But in a match like that it's quite tough."
