Down 5-0 in the first set, the former No. 1 player beats Karolina Muchova in three sets to make a Grand Slam third round for the first time in three years

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.

The two-time Australian Open champion advanced to the third round of the tournament on Wednesday with an upset 1-6, 6-1, 6-3 win over No. 20 seed Karolina Muchová. The win was also a reversal of the pair's meeting in the 2024 US Open, which Muchová won 6-3, 7-6.

Naomi Osaka beat Karolina Muchova 1-6, 6-1, 6-3 at the Australian Open, reaching the third round at a Grand Slam for the first time since her return from maternity leave.

Naomi Osaka has admitted she was out for “revenge” against Karolina Muchova at the Australian Open. The two-time former champion came from a set down to beat the Czech star on Wednesday - months after Muchova ousted her from the US Open. Afterwards, Osaka explained why she was “so mad” the last time the world No. 20 beat her.

Australian Open star Destanee Aiava has spoken out after constantly being mistaken for fellow WTA Tour ace Naomi Osaka. Aiava progressed into the second round of her home Grand Slam with a 2-1 victory over Belgian player Greet Minnen in game one.
