Barbora Krejčíková defeated Taylor Townsend 6–1, 7–6, 6–3 in the US Open Round of 16 on hard court on 31 August 2025, confirming her status as pre-match favourite with odds of 1.79 to Townsend's 2.15. After surrendering the opening set, Krejčíková recovered to claim a competitive second-set tiebreak before consolidating her advantage in the third. The Czech player's ability to reset following the first-set loss demonstrated composure under pressure, whilst her eventual progression maintains her trajectory in the latter stages of the year's final Grand Slam. Krejčíková's quarter-final berth represents a significant checkpoint in her campaign to challenge for a major title.
