NEW YORK — Karolina Muchova is back in the US Open semifinals for the second straight year, punctuating her return from wrist surgery by beating No. 22 Beatriz Haddad Maia 6-1, 6-4 on Wednesday.
Muchova lost to eventual champion Coco Gauff in the 2023 semis in Flushing Meadows, then missed nearly 10 months because of a wrist injury she suffered during the tournament.
The Czech returned to action in June just before Wimbledon, and a little more than two months later she is into her fourth career Grand Slam semifinal.
Muchova will face top-seeded Iga Swiatek or No. 6 Jessica Pegula on Thursday in the semifinals.
Muchova dominated the first set, racing to a 5-0 lead and finishing it off in 35 minutes. Then it became a test in the second, with both players struggling physically on a sunny afternoon.
Muchova, who was grabbing at her hip, left the court at one point for what she said was a needed trip to the bathroom, while Haddad Maia appeared to be pointing to her chest and trying to breathe deeply midway through the set before burying her head in a towel as trainers attended to her.
“A little weird match, I have to say,” Muchova said in her on-court interview. “I had little problems, I wouldn’t like to comment on it actually if it’s fine. But I’m happy I managed it, to run to the bathroom and back. Sorry if it disturbed anyone, but I had no other choice.”
Muchova has had to get used to dealing with pain.
She had just made her second major semifinal of 2023, having lost to Swiatek in the French Open final, when she had to stop playing following the US Open. When she finally got back to the tour this year, it left time for only 11 matches before returning to Flushing Meadows.
That was enough time for Muchova to rediscover her game. She hasn’t dropped a set in her five matches and finished off this one with an ace down the middle.
Many fans hadn’t even taken their seats at Arthur Ashe Stadium when Muchova broke Haddad Maia in a 14-point game to take a 2-0 lead. The Brazilian faced that same deficit in her third-round match against Anna Kalinskaya but won the next game to start a turnaround, helped in part by a video review that gave her a point.
The U.S. Tennis Association acknowledged the next day that Haddad Maia’s shot was illegal, but the chair umpire wasn’t given the relevant replay that would have shown that.
Muchova wouldn’t allow a turnaround this time, denying Haddad Maia — the first Brazilian woman to make the US Open quarterfinals since Maria Bueno in 1968 — what would have been the second major semifinal of her career.
Muchova is the 19th unseeded woman in the Open era to reach the semifinals in New York, and only the fifth to do so without a dropping a set, alongside Mima Jausovec (1976), Flavia Pennetta (2013), Peng Shuai (2014) and qualifier Emma Raducanu, who won the title in 2021.
