Serena Williams and Carlos Alcaraz defeated Erin Routliffe and Lloyd Glasspool 5-3, 4-1 [1] in their opening mixed-doubles match on Tuesday [2].

The victory marks a high-profile start for the duo in a revamped mixed-doubles format introduced for the 2026 U.S. Open. The pairing of a legendary champion and a current top star draws significant global attention to a category often overshadowed by singles play.

The match took place at Arthur Ashe Stadium in New York [1]. The contest began at 11:00 a.m. EDT [3], drawing a massive crowd to witness the collaboration between Williams and Alcaraz. The pair maintained control throughout the match, securing the win with a final score of 5-3, 4-1 [1].

This tournament features a redesigned approach to mixed doubles intended to increase the visibility of the event [4]. By pairing marquee names like Williams and Alcaraz, organizers aim to elevate the prestige of the draw. The opening round victory puts the pair in a strong position as the tournament progresses through the early stages.

While the opening round ended in a victory, some reports indicate the pair faced challenges later in the bracket. One report said that while the duo won their first-round match, they were subsequently beaten in the quarterfinals [1]. This suggests a volatile run for the high-profile team despite their dominant start on Tuesday.

The U.S. Open continues to integrate these experimental formats to evolve the spectator experience. The presence of Williams back on the court at Arthur Ashe Stadium remains a primary draw for fans and sponsors alike.
