I have heard before that he uses a semi western backhand grip with his dominant (left) hand. This is the most extreme one handed backhand grip you can get. And with his non-dominant (right) hand he uses a Hawaiian grip. This is the most extreme forehand grip you can get. Does this grip combo ensure that he hits the most topspin on the backhand out of anyone on the ATP tour? Also, does any other pro use a semi western backhand grip with their dominant hand on the two handed backhand? What about Djokovic and Murray?
