The U.S. Open's largest court was packed for the final three matches of the reimagined mixed doubles tournament Wednesday night, which was made up of mainly top singles players for the first time.

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.

Fans flocked to New York and mixed doubles was the star of the show — but there remains a fundamental flaw with the new-look tournament

The semifinals of the new-look U.S. Open mixed doubles championship are set, with the title being decided tomorrow. The teams of Iga Świątek/Casper Ruud and Sara Errani/Andrea Vavassori advanced in the early wave, and they will be joined by Danielle Collins/Christian Harrison and Jessica Pegula/Jack Draper.

Italians Andrea Vavassori and Sara Errani won the U.S. Open's reimagined mixed doubles event Wednesday night, withholding WTA world No. 2 Iga Świątek and ATP world No. 12 Casper Ruud in a 10-point tiebreak for the third set and the match.

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.
