Sara Errani and Andrea Vavassori weren't even sure they would get to defend their US Open mixed doubles title. Organizers revamped the tournament because they wanted singles superstars, not doubles specialists.

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.

Everyone has been talking about the revamped US Open mixed doubles but the other Grand Slams are unlikely to follow suit soon.

Some of the biggest stars in men's and women's tennis will take the court together at the US Open for a reimagined mixed doubles competition.

The thought of the top men’s and women’s singles players teaming up is one that has often intrigued tennis fans around the world.

Grand Slam singles champions such as Jannik Sinner, Carlos Alcaraz, Iga Swiatek and Madison Keys will be playing for extra money — $1 million to the winning duo — and trying to get their hands on a trophy in the U.

The winning duo will take home a $1 million prize, which is higher than most prize purses for mixed doubles major tournaments. The 16 teams will play over two days. The first round and quarterfinals take place on Tuesday inside the main show courts at the USTA National Tennis Center. The semifinals and championship match will be on Wednesday night.
