Olympic champion Zheng Qinwen won’t be repeating her surprising run to the Australian Open final in 2025 after a second-round upset loss to No. 97-ranked Laura Siegemund on Wednesday. Zheng lost the 2024 championship match at Melbourne Park to Aryna Sabalenka and went on to win the Olympic gold medal in Paris and finish runner-up at the WTA Finals in a breakout season.

The 1-6, 6-1, 6-3 victory over Karolina Muchova allowed Osaka to reach the third round at a major tournament for the first time since the 2022 season.

A four-time Grand Slam champion, Osaka returned from maternity leave last year and lost in the first or second round of all four major tournaments. The 27-year-old Japan native has not won any event on the WTA Tour since capturing her second Australian Open title to start 2021.
