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

Naomi Osaka lost to Victoria Mboko in the WTA 1000 Montreal final, but her comeback is still moving in the right direction.

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.
