Tokyo, Jul 22: Naomi Osaka's first match in nearly two months will come against 52nd-ranked Zheng Saisai of China in the opening round of the Olympic tennis tournament.

The second-seeded Osaka, who represents host Japan and is one of the top names at the Games, is returning to competition after she withdrew from the French Open following the first round to take a mental health break. Osaka holds a 2-1 career edge over Zheng.

The first seeded opponent that Osaka could face is No. 16 Kiki Bertens, who is playing the final tournament of her career. Iga Swiatek, the 2020 French Open champion, is a possible quarterfinal opponent for Osaka. Tokyo Olympics 2020: List of Sports Events at the 32nd Summer Games.
