For better or for worse, definitely for richer, and for who knows how long, the reimagined, star-spangled U.S. Open mixed doubles tournament gets underway Tuesday, Aug. 19 at the Billie Jean King National Tennis Center in New York.

The US Open will crown its first champions of the 2025 tennis tournament on Wednesday night as mixed doubles takes center stage in New York.

The event sparked controversy because it excluded traditional doubles teams - except for Errani and Vavassori - at the expense of big-name singles players. The star-studded field included world No. 2 Iga Swiatek and three-time Grand Slam singles finalist Casper Ruud, who lost in the final to the Italians, 6-3, 5-7, 10-6.

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 No. 1-ranked Sinner, the defending champion in singles at Flushing Meadows, was supposed to compete in mixed doubles with Katerina Siniakova.

The much-talked-about pairing of Emma Raducanu and Carlos Alcaraz fell to an early exit in the US Open’s mixed doubles competition on Tuesday, losing their first-round match and failing to win a set.

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.
