MELBOURNE, Australia (AP) — 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.

Naomi Osaka defeated No. 20 Karolina Muchova 1-6, 6-1, 6-3 on Wednesday to reach the third round of a major for the first time since the 2022 Australian Open.

Distracted by a time penalty and unable to counteract No. 97-ranked Laura Siegemund's aggressive approach, Zheng Qinwen's loss in the second round Wednesday fell a long way short of last year's run to the Australian Open final.

Naomi Osaka said she was enjoying a little bit of revenge against Karolina Muchova at the Australian Open on Wednesday, recalling how the Czech had ended her U.S. Open campaign last year when she was sporting her "best outfit ever".

Naomi Osaka showcased her champion mentality in a thrilling three-set victory during her second-round match at the Australian Open, overcoming a stern test against Karolina Muchova to keep her title hopes alive.
