Elena Rybakina retires from her Cincinnati Open quarter-final against Iga Swiatek due to an ankle injury. Multiple reports say she is forced to withdraw mid-match, leaving Swiatek to advance to the semifinals.
With the U.S. Open scheduled shortly after, the injury becomes part of the broader preparation context for the hard-court Grand Slam. Separately, Jessica Pegula reaches the semi-finals after defeating Amanda Anisimova in three sets. Across outlets, the reported match details differ slightly, including how far Rybakina had progressed before retiring, but all describe a retirement prompted by an ankle issue and a resulting semifinal pairing of Swiatek against Pegula.
