This wasn’t just a victory for Sara Errani and Andrea Vavassori. Their US Open mixed doubles title also felt like a victory for all doubles tennis players.

Sara Errani and Andrea Vavassori retained their US Open mixed doubles title on Wednesday, beating Iga Swiatek and Casper Ruud to claim the $1 million top prize in the new-look competition that kicked off action at the last Grand Slam of the year.

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