Canadian teenager Victoria Mboko defied a swollen right wrist to come from a set down on Friday to outwit the four-time major champion Naomi Osaka and claim her first senior tour title at the Canadian Open.

Victoria Mboko didn’t even have a picture on the WTA website before the National Bank Open in Montreal. Now, the 18-year-old is set to face Naomi Osaka in the first WTA final of her career.

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.
