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.

Naomi Osaka struggled to build upon an early edge in her matchup with Victoria Mboko in the 2025 Montreal Open Final.

In the National Bank Open, Canadian teenager Victoria Mboko clinched the title by defeating Japan`s star Naomi Osaka in the final. The Canadian defeated Osaka by 2-6, 6-4, 6-1 in the title clash. The win also marked the 18-year-old`s first-ever WTA title.
