Carlos Alcaraz and Emma Raducanu face off against Jessica Pegula and Jack Draper in the Mixed Doubles first round today, Aug. 19, at approximately 2:40 p.m. ET. The first day of the US Open Mixed Doubles tournament is airing on the ESPN+ streaming service.

Carlos Alcaraz and Emma Raducanu’s early exit from the US Open wasn’t exactly a shock. Star singles players don’t always make great doubles partners. The last successful pairing of singles champions was the Williams sisters — Serena and Venus — but they had the advantage of playing together since childhood.
