Naomi Osaka struggled to build upon an early edge in her matchup with Victoria Mboko in the 2025 Montreal Open Final.

Osaka has made progress since returning in last year's Australian Open. She won two matches in both the Australian Open and Wimbledon this year, has earned $725,727 in prize money and reached the No. 49 spot in the WTA rankings, with a higher ranking likely on the way by making the final.

Naomi Osaka’s return to the court at the Canadian Open should have been a “welcome back” moment. Instead, it turned into an awkward PR disaster that had fans and critics raising their eyebrows.
