Anna Bondar defeated Elina Svitolina 6–2, 6–4 in the first round of the US Open on hard court on 25 August 2025, recording a significant upset against the heavy favourite. Svitolina entered as the overwhelming pre-match favourite at odds of 1.08, whilst Bondar was priced at 10.22, yet the Ukrainian qualifier dominated proceedings to secure a commanding two-set victory. The emphatic scoreline suggests Bondar controlled the baseline exchanges and converted her opportunities efficiently, whilst Svitolina struggled to impose her game on the court. The result marks a notable early exit for Svitolina at the Grand Slam and represents a career-defining moment for Bondar, who will now face a seeded opponent in the second round with considerable momentum.
