Victoria Mboko stuns Naomi Osaka to win National Bank Open

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.

The 18-year-old Mboko — who will jump from 85th to 25th in the world — 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.

Mboko dropped to her knees after Osaka fired a shot into the net as a raucous packed house burst into cheers around center court. The crowd was so rowdy, the umpire repeatedly asked fans to “please be quiet during the points.”

There were 13 service breaks in 25 games, with Mboko converting eight of nine break points.

Born in Charlotte, North Carolina, to Congolese parents, Mboko grew up in Toronto. She beat four majors champions in the hard-court event, routing top-seeded Coco Gauff 6-1, 6-4 and also topping Osaka, Sofia Kenin and Elena Rybakina.

Osaka, the four-time Grand Slam champion who reached No. 1 in the world, had her best performance in a WTA 1000 tournament since also 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’s winless since the 2021 Australian Open.

Mboko is the third wild card to win a WTA 1000 title event, following Maria Sharapova at Cincinnati in 2011 and Andreescu at Indian Wells in 2019.
