Can you feel it coming in the air tonight? Caroline Wozniacki can. The Dane had a little fun imitating the drummer for ESPN (it seems to be a trend at the US Open). She sounds pretty good—maybe Collins should take her up on that backup drummer offer.

Wozniacki is enjoying her best major performance of the year, reaching the third round with a strong win over Svetlana Kuznetsova. Next up for the world No. 74 is eighth-seeded Madison Keys.
