US Open (September 1): Full Schedule, Timings, When and where to watch and more - Coco Gauff-Naomi Osaka battle for a place in quarterfinals

A blockbuster fourth-round clash awaits at the US Open on Monday, as Coco Gauff and Naomi Osaka battle inside Arthur Ashe Stadium for a place in the quarterfinals. Gauff, the 21-year-old third seed from Florida, continues her rise as one of the sport’s brightest stars, while Osaka, the 27-year-old No. 23 seed, is aiming to reclaim her former dominance.

The two players own three US Open titles between them as Osaka triumphed in 2018 and 2020, while Gauff lifted the trophy last year. Their showdown will follow the men’s fourth-round contest between Andrey Rublev and Felix Auger-Aliassime, which begins at 11:30AM ET.


This matchup carries added history. In 2019, Osaka defeated a then-15-year-old Gauff in straight sets, before consoling her in an emotional moment that remains one of the tournament’s most memorable scenes. Since then, Gauff has matured into a Grand Slam champion and has flipped the rivalry in her favor, winning three of their last four encounters to lead the head-to-head 3-2.

Osaka, a four-time major winner, remains dangerous with her explosive baseline game. Meanwhile, Gauff has sharpened her serve under new coaching guidance, helping her claim the 2024 French Open.
