Novak Djokovic, Coco Gauff roll to Australian Open's 4th round. Naomi Osaka retires due to injury and Jessica Pegula was upset in the third round.

Coco Gauff still hasn't lost a match or even at set at the Australian Open — or, actually, this season. She moved into the fourth round at Melbourne Park with a straightforward 6-4, 6-2 victory over 2021 U.

While there have been plenty of surprises in the men’s bracket so far, most of the top women have progressed through the draw without an issue.
