Lesia Tsurenko defeated Bianca Andreescu 6-0, 6-3, 6-4 in the first round of the Canadian Open in Toronto on hard court on 6 August 2024, delivering a significant upset against the pre-match favourite. Andreescu, seeded higher with odds of 1.25, suffered a dominant opening set before rallying in the second frame, yet Tsurenko's momentum proved irreversible as she closed out the match in the third set. The Ukrainian's clinical performance—particularly her commanding first-set display—overwhelmed the Canadian's attempts at recovery. This result marks a notable setback for Andreescu's form at a Masters 1000 event and demonstrates Tsurenko's capacity to trouble higher-ranked opponents on hard courts.
