Now this is TENNIS.

Just remembering greatness. 

This has to be the best thing I've seen from Petko (and that's saying A LOT). She should definitely make more of this vids, I would pay serious money for them. The Petko-Novak combo blows my mind, or may I say blows my lungs because I can't stop laughing. It would be an understatement to say I find her one of the coolest-nicest-rock stars in tennis. 

Stay amazing Petko. We need you!
