Two-time defending Australian Open champion Aryna Sabalenka extended a few impressive streaks on Friday while becoming one of the first players to advance to the fourth round of the year's opening Grand Slam tournament.

Naomi Osaka, ranked just No. 51 in the world after a disappointing 2024 season, shook off a slow start en route to a second-round upset win in the Australian Open on Wednesday.

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.
