Overview
- Muchová beat Marta Kostyuk 6-3, 6-7 (0-7), 6-3 to advance to the quarterfinals and is slated to face Naomi Osaka.
- During her second-round match against Sorana Cîrstea, she became tearful after spotting an ex-partner seated near her player box.
- She briefly halted play, asked the man to leave, saw him initially refuse before departing, and apologized for the delay.
- Muchová said she did not report the incident to the US Open organizers or the WTA, so no formal exclusion process was initiated.
- Tournaments and the WTA now allow players to submit names for exclusion, a policy reinforced after Emma Raducanu earlier raised concerns about a spectator in Dubai.
