Victoria Mboko upset second-round favourite Coco Gauff 6–1, 6–4 at the WTA 1000 Montreal event on hard court in the Round of 16. Despite Gauff's pre-match odds of 1.44 to Mboko's 3.05, the underdog delivered a commanding performance to advance decisively. Mboko's dominance in the first set, where she claimed six games to one, set the tone for the encounter, and she maintained control in the second to secure the victory in straight sets. The result marks a significant upset in the Canadian Masters and represents a notable scalp for Mboko at this level, while Gauff will need to reassess her form heading into the latter stages of the North American hardcourt swing.
