Canadian teenager Victoria Mboko has rocketed 61 spots to a career-best No. 24 in the world rankings after winning her first career WTA Tour title at the National Bank Open.
The 18-year-old from Toronto upset four-time Grand Slam champion Naomi Osaka of Japan in a three-set final in Montreal on Thursday night.
Mboko, who grew up in Burlington, Ont., has enjoyed a meteoric rise this season.
She ended the 2024 campaign at No. 350 in the world and has since gone on a 53-9 tear, earning almost US$1.2 million in prize money along the way.
Mboko will take a break to rest her sore right wrist before beginning preparation for the U.S. Open in New York, where she'll be a seeded player at a Grand Slam for the first time.
Mboko also became the highest-ranked Canadian on the tour. Leylah Fernandez of Laval, Que., the only other Canadian in the top 100, dropped two positions to No. 26.
