Big names fell early and unexpected teams broke through to steal the spotlight on Day 1 of U.S. Open mixed doubles play, headlining an electric opener packed with upsets and standout performances.

The new Mixed Doubles format for the 2025 US Open has allowed more of the top singles players to participate in the event, and on Tuesday, Aug. 19 in New York, the Mixed Doubles tournament begins.

Watch highlights as Emma Raducanu and Carlos Alcaraz are beaten 4-2 4-2 by Jack Draper and Jessica Pegula in the revamped US Open mixed doubles.

The thought of the top men’s and women’s singles players teaming up is one that has often intrigued tennis fans around the world.

The new event wanted to use singles stars to put mixed doubles on a pedestal. Two masters of the discipline have stolen the show.

Grand Slam singles champions such as Jannik Sinner, Carlos Alcaraz, Iga Swiatek and Madison Keys will be playing for extra money — $1 million to the winning duo — and trying to get their hands on a trophy in the U.

Viewers in the UK can watch the mixed doubles at the US Open live on Sky Sports Tennis. The event is being streamed on ESPN in the United States. The full 16-team field was decided by the top-8 singles rankings combined, and eight wildcard picks.
