Eighteen-year-old Canadian tennis player Victoria Mboko won her first WTA Tour title by defeating former world No. 1 Naomi Osaka at the National Bank Open in Montreal. Mboko, ranked 85th in the world, came back from a set down to win the final with a score of 2-6, 6-4, 6-1. This victory marked a remarkable rise for Mboko, who was ranked 333rd at the end of the previous season and had been competing in lesser-known tournaments. The win was described as a major upset, with Mboko overcoming four Grand Slam champions during the tournament. Following the match, Osaka declined to participate in media duties and did not acknowledge Mboko's victory publicly. The final was held alongside the men's final in Toronto, where Ben Shelton won his first Masters 1000 title by defeating Karen Khachanov. Both Mboko and Osaka have since withdrawn from the Cincinnati Open. Mboko's family includes three tennis-playing siblings, and her breakthrough has drawn significant attention in Canadian tennis circles.
