Naomi Osaka defeated Hailey Baptiste 6–3, 6–1 in the first round of the US Open on hard court, confirming her status as the pre-match favourite with odds of 1.22 against Baptiste's 4.84. The Japanese former champion's dominance was evident from the outset, with Baptiste unable to sustain competitive pressure across either set. Osaka's clinical performance—particularly her control in the second set—suggests she has entered the tournament with considerable momentum. The margin of victory underscores the gap between the two players' current form and pedigree, with Osaka advancing smoothly to the second round where further tests await.
