Defending champions trump singles stars in early US Open mixed doubles

NEW YORK :Veteran doubles experience overcame singles stardom as defending champions Andrea Vavassori and Sara Errani reached the semi-finals at the U.S. Open's reimagined mixed doubles on Tuesday, as the event kicked off with a new format and new fans.

The semis and final are set for Wednesday.

"Last two days felt like one long day but I'm super happy to be here and playing with Casper," said Swiatek. "Didn't have time to play many doubles to practise but I think I can
