Canadian teenager Victoria Mboko completed a dream run to the National Bank Open title Thursday night, overcoming a slow start to beat Japanese star Naomi Osaka 2-6, 6-4, 6-1.

Mboko, 18 and playing in her first WTA final, denied Osaka her first tour-level title since the 2021 Australian Open. Despite being a set down, she wore down the Japanese star, 27, who has struggled to find consistency since returning from maternity leave early in 2024.

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