Serena Williams and Carlos Alcaraz are knocked out of the U.S. Open mixed doubles quarterfinals. After a strong start as a star pairing, they lose to Flavio Cobolli and Belinda Bencic and do not reach the later stages of the tournament.

Multiple outlets report that Cobolli and Bencic go on to advance from the quarterfinal round. The BBC and others describe the match result, with Williams and Alcaraz losing 5–4 (7–4), 4–1. Coverage also notes that the U.S. Open mixed doubles format and the prominence of the pairing drive attention to the tie, though outlets differ slightly in wording about the “dream team” angle.

Regarding the next round, Al Jazeera and The Hindu both state that Cobolli and Bencic play married partners Elina Svitolina and Gaël Monfils in the semifinal. Other reports focus more on the Williams–Alcaraz run ending in the last eight, while listing additional notable tournament exits in broader sports context.
