Alexandra Eala defeated Clara Tauson 6–3, 2–6, 7–6 in the first round of the US Open on hard court, pulling off an upset against the pre-match favourite. Tauson, who entered with stronger odds at 1.36 to Eala's 3.4, won the second set convincingly to level the match, but Eala regrouped in a tight decider to secure the tiebreak and advance. The Filipino's ability to recover after dropping the middle set proved decisive in a three-set encounter that showcased contrasting momentum shifts. Eala's victory represents a significant scalp at the Grand Slam level and should provide confidence heading into the second round.
