Iga Świątek defeated Caty McNally 5–7, 6–2, 6–1 in the first round of Wimbledon on grass on 3 July 2025, confirming her status as the overwhelming pre-match favourite. McNally made a competitive start, claiming the opening set in a tight affair, but Świątek's superior court control asserted itself decisively in the second and third sets as the American's resistance crumbled. The Polish world number one's transition from clay to grass proved seamless, with McNally unable to sustain the level required to trouble the favourite on the faster surface. Świątek's progression to the second round maintains her bid for a maiden Grand Slam title on grass.
