Naomi Osaka advances to US Open third round after beating Kateřina Siniaková

Naomi Osaka advanced to the third round of the US Open after a three-set victory over Kateřina Siniaková at Arthur Ashe Stadium. Following a second-set loss, Osaka took a bathroom break to regroup before winning five of the final six games to finish the match 6-2, 5-7, 6-1. The former champion noted that she used the break to refocus and avoid being overly self-critical after missing opportunities earlier in the match. She also commented on the need for better crowd management following recent tournament incidents involving spectator behavior. Osaka is scheduled to face 23rd seed Elise Mertens in the next round. Elsewhere at the tournament, Iga Świątek defeated Nadia Podoroska, while Amanda Anisimova and Madison Keys also secured victories in their respective matches.
