Victoria Mboko didn’t even have a picture on the Women’s Tennis Association (WTA) website before the Canadian Open in Montreal. Now, the 18-year-old has defeated four-time grand slam champion Naomi Osaka in the first WTA Tour final of her career.

Osaka has made progress since returning in last year's Australian Open. She won two matches in both the Australian Open and Wimbledon this year, has earned $725,727 in prize money and reached the No. 49 spot in the WTA rankings, with a higher ranking likely on the way by making the final.

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