Four-time major champion Naomi Osaka powered into the U.S. Open fourth round on Saturday with a 6-0, 4-6, 6-3 win over 15th seed Daria Kasatkina to continue her best Grand Slam run since 2021.

Osaka lit up Louis Armstrong Stadium in broad daylight, turning her third-round clash into a showcase of power and composure.

The Japanese star dominated early, absorbed a brief second-set wobble, and closed out the win to set up a fourth-round showdown with American third seed Coco Gauff.
