Camila Giorgi defeated Bianca Andreescu 6–3, 6–2 in the first round of the Montreal Masters 1000 on hard court on 8 August 2023, an upset against the pre-match favourite. Andreescu entered as the betting favourite at 1.76 odds, but Giorgi's dominant performance—winning both sets comfortably—proved decisive. The Italian's clinical execution and Andreescu's inability to impose her game resulted in a straightforward victory that underlined Giorgi's capacity to trouble top-seeded opponents on the WTA circuit. The result marked a significant scalp for Giorgi and raised questions about Andreescu's form heading into the latter stages of the North American hard-court season.
