Elise Mertens vs Naomi Osaka — R32 — Canadian Open

The return games settled it. Osaka converted four of eight break points and never faced more than three all match, saving all three, while Mertens held just three of seven service games and went 0-for-3 on her own chances. Two of those breaks came early in the second, in game 5 for 3-2 and game 7 for 5-2, Osaka winning 85% of her first-serve points across 70 minutes to even their meetings on record at two apiece. The No. 11 seed draws Leylah Fernandez, No. 34 at the time, next.
