Naomi Osaka caused a stir during her on-court comments following her loss to Victoria Mboko in the final of the National Bank Open Thursday night in Montreal. Mboko, an 18-year-old Canadian of Congolese descent, came back from a set down to beat Osaka 2-6, 6-4, 6-1 to win the WTA title in her home country.

Canadian teenager Victoria Mboko completed a dream run to the Canadian Open title on Friday (August 8, 2025), 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.
