Serena, Alcaraz Lose US Open Mixed Quarterfinal

Serena Williams and Carlos Alcaraz lost their US Open mixed doubles quarterfinal 5-4 (4), 4-1 to Belinda Bencic and Flavio Cobolli on Tuesday. The WTA reported that the fourth seeds needed 55 minutes to end the most watched run of the new mixed event. Williams and Alcaraz had won their opener earlier in the day, but the second match proved one step too far.

Bencic and Cobolli won all four sets they played Tuesday. Against Williams and Alcaraz, they took the final four points of the first-set tiebreak, then earned the decisive break for a 3-1 lead in the second. Bencic finished a key point with a volley at Alcaraz's feet before Cobolli served out the match. Sky Sports carried the same 5-4, 4-1 final.

What was the Serena Alcaraz mixed doubles score?

The quarterfinal score was 5-4 (4), 4-1. The compact tournament used first-to-four sets, no-ad scoring and a tiebreak at 4-4. That made the opening-set tiebreak especially costly. Bencic and Cobolli took it, then controlled the second set without needing a match tiebreak.

Williams and Alcaraz had rallied from 3-1 down to beat Erin Routliffe and Lloyd Glasspool 5-3, 4-1 in the first round. That opening win was Williams' first professional victory since 2022. There was little recovery time before the quarterfinal. Sky Sports said the quick turnaround caught up with the star pair.
