Carlos Alcaraz and Serena Williams faced a demanding test during their mixed doubles debut at the US Open, according to reports from outlets like Gazzetta.it and Punto de Break. After battling through a first-round win against Erin Routliffe and Lloyd Glasspool, the high-profile wild card pairing fell in the quarterfinals to Belinda Bencic and Flavio Cobolli with a scoreline of 5-4(4), 4-1. The tournament, featuring a one-million-dollar prize for the ultimate winners, brought together two massive tennis stars before fatigue and formidable opponents ended their run.
The Opening Victory Against Routliffe and Glasspool
According to Gazzetta.it, Alcaraz returned to competitive play after 113 days away from the court, partnering with former world number one Serena Williams. In their opening match against Erin Routliffe and Lloyd Glasspool, the pair overcame early jitters. Routliffe and Glasspool pushed for set points in the opening frame as Alcaraz found his footing, but the star duo rallied with crowd support to secure a 5-3, 4-1 victory.

Punto de Break noted that Alcaraz showed improved serving rhythm compared to his initial struggles, successfully converting key points under pressure. With the tournament format requiring players to reach four games to win a set, the quick-fire structure demanded immediate focus from both competitors.
Quarterfinal Exit Against Cobolli and Bencic
The quarterfinal clash pitted Alcaraz and Serena against fourth seeds Belinda Bencic and Flavio Cobolli, who ultimately proved too strong. Gazzetta.it reported that fatigue and lack of regular practice together caught up with the veteran-and-star pairing, particularly given Serena’s return to activity in June and Alcaraz’s recovery from a wrist injury.

Punto de Break highlighted that Alcaraz and Serena failed to earn a single break point during the match. Cobolli dominated the court in the second set, targeting Serena with precise groundstrokes and breaking Alcaraz’s serve to take a 3-1 lead. Cobolli and Bencic closed out the straight-sets win to advance to the semifinals.
