Kei Nishikori vs. Milos Raonic 

This is sort of like George Foreman vs. Floyd Mayweather.  One player hits heavy shots and blasts away with punishing power generated by a powerful frame.  The other player generates power through exquisite timing.  In a boxing match, I would take Foreman over Mayweather because no one in boxing can give up that much weight and beat a fighter who knows what he is doing.  Fortunately for Nishikori, he does not have to fight Raonic.  He gets to play tennis.

My Prediction: Kei Nishikori d. Milos Raonic 6-4, 6-7, 6-2.
