Caroline Wozniacki defeated Nao Hibino 6–0, 6–1 in the first round of the US Open on hard court on 27 August 2024, confirming her status as pre-match favourite with odds of 1.21 to Hibino's 4.93. The Danish former world number one's dominant performance saw her concede just one game across two sets, reflecting a significant gulf in class between the seeded veteran and her Japanese opponent. Wozniacki's clinical display suggested she had returned from retirement in sharp form, though the one-sided nature of the contest offered limited insight into her readiness for stiffer competition in the tournament's later stages.
