Defending US Open champ Sabalenka returns to semifinals when Vondrousova withdraws with knee injury
September 2, 2025
Defending champion Aryna Sabalenka has returned to the U.S. Open semifinals without hitting a ball in the quarterfinals. The No. 1-ranked Sabalenka was supposed to play Marketa Voundrousova on Tuesday night. But Vondrousova withdrew from the match with an injured knee. The U.S. Tennis Association announced the walkover about two hours before the match was supposed to begin. Sabalenka now will meet No. 4 Jessica Pegula in the semifinals on Thursday. That is a rematch of last year’s championship match at Flushing Meadows, which Sabalenka won in straight sets.
