MONTREAL — 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, won her first WTA Tour title and joined Faye Urban in 1969 and Bianca Andreescu in 2019 as the only Canadians to win the home event in the open era.

Born in Charlotte, North Carolina, to Congolese parents, Mboko grew up in Toronto. Ranked 85th in the world, she upset top-seeded Coco Gauff 6-1, 6-4 on Saturday to reach the quarterfinals.

Osaka, a four-time Grand Slam champion who reached No. 1 in the world, had her best performance in a WTA 1000 tournament since reaching the Miami final in 2022. She stepped away for 15 months toward the end of that season and had daughter Shai in July 2023. She has not won a tournament since the 2021 Australian Open.
