Naomi Osaka, ranked 23rd, will face Amanda Anisimova, ranked 8th, in the US Open Women's Singles Semifinal on Thursday, September 4, 2025, at 8:10 PM ET. The match will be broadcast on ESPN and available for streaming on Fubo.

Osaka, a two-time US Open champion, is making her return to the Grand Slam semifinals after a hiatus for maternity and mental health. She reached this stage by defeating Karolína Muchová in the quarterfinals with a score of 6–4, 7–6(3). This victory marks her fifth consecutive win in Grand Slam quarterfinals.

Anisimova enters the semifinal with significant momentum, having upset world No. 2 Iga Świątek in straight sets. The 8th seed has displayed aggressive baseline play and renewed confidence throughout the tournament, making this one of her best performances in New York.

Historically, Anisimova leads their head-to-head matchups 2–0, having defeated Osaka at both the 2022 Australian Open and Roland Garros. The upcoming match poses the question: will Osaka secure her first final as a mother, or will Anisimova achieve her breakthrough moment by advancing to her first US Open final?

In another semifinal, top-ranked Aryna Sabalenka will compete against fourth-ranked Jessica Pegula at 7:00 PM ET on the same day. This match is a rematch of last year's final, where Sabalenka emerged victorious in straight sets.

Pegula has been impressive in the tournament, advancing without dropping a set and allowing only 21 games through her first five matches. She will be looking to leverage her home-court advantage, but she faces the challenge of overcoming her past struggles against Sabalenka.

Sabalenka, the defending champion, enters the match with fresh legs after receiving a walkover in the quarterfinals due to Marketa Vondrousova's injury. She holds a 7–2 advantage in their head-to-head matchups, with all three recent victories occurring on North American hard courts.

As both matches promise to be thrilling encounters, fans are encouraged to tune in and catch all the action. Regional restrictions may apply.
