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.
