Top Women’s Match: Naomi Osaka v Aryna Sabalenka

Japan’s Osaka will be hoping it will be fourth time lucky when she faces Sabalenka, having lost all three of their meetings this year — at Indian Wells, Madrid and the French Open.

Prior to 2026, the pair had not crossed paths for over seven years, with Osaka winning their first-ever clash en route to her maiden Grand Slam triumph at the U.S. Open in 2018.
