Former world No. 1 Caroline Wozniacki advanced to the third round of the US Open, defeating Renata Zarazua in straight sets. However, the tournament saw a major upset as Naomi Osaka was eliminated by Karolina Muchova in a hard-fought match. Osaka, a four-time Grand Slam champion, has struggled to find consistency since her Australian Open win in 2021. Wozniacki, who retired from tennis in 2020, returned to the sport this year and is making a strong comeback.
