Benoit Paire's recent drop shot at the Paris Masters may be the most perfect example of the shot we've ever seen.
Talk about using physics to your advantage. The Frenchman's racket face was nearly horizontal as he applied the perfect backspin to his drop shot volley against countryman Gilles Simon.
The ball almost hit Paire in the face before floating over, bouncing, and spinning out of Simon's reach and very nearly back over the net.
Unfortunately for Paire, he still went on to lose the match, but that shot is worth watching again.
