NEW YORK -- Defending champion Aryna Sabalenka returned to the US Open semifinals without hitting a ball on Tuesday night because the woman she was supposed to face in the quarterfinals, 2023 Wimbledon champion Marketa Vondrousova, pulled out of their match with an injury.
The U.S. Tennis Association's announcement of the walkover -- about two hours before the match was scheduled to begin in Arthur Ashe Stadium -- did not specify what was wrong with Vondrousova, though she was seen walking with a wrap around her left leg.
Vondrousova, a 26-year-old left-hander from the Czech Republic, had advanced to the quarterfinals with a three-set victory over 2022 Wimbledon champion Elena Rybakina on Sunday night.
