Vavassori moves very well at the net," Ruud explains the difficulty of returning Errani's serve in doubles

Sara Errani is known on the WTA tour for having a relatively weak serve. However, in doubles, it is very tricky, as explained by Casper Ruud, her opponent in the US Open mixed doubles final.
He states: "They complement each other perfectly because Andrea moves very well at the net. Singles players don't think to cross when someone serves at 110 km/h.
We're not used to seeing that on our own returns. The most frustrating part is when we think we've made a good return, Vavassori is there and puts away a volley.
It's a mix of a different rhythm for her and incredibly smooth movement for him. They know each other very well; they've played together in every Grand Slam tournament.
They get along well. It was both fun and frustrating to see us miss forehand returns when we shouldn't have. Kudos also to Andrea for his speed and precision at the net.
