Osaka fought through tough competition to reach the second week at Flushing Meadows. She opened her campaign by defeating Anastasia Zakharova in two tiebreak sets, winning 7-6(8), 7-6(7).

She then defeated Kateřina Siniaková 6-2, 5-7, 6-1 in the second round. In the third round, Osaka faced Elise Mertens and came away with a 6-3, 3-6, 7-5 victory.

Aside from her performance on the court, Osaka has also drawn attention for her fashion statements during her walks to the court. At this year's tournament, she paid homage to NBA legend Allen Iverson with a custom outfit.
