What grip does he use? How in the world does he come up with such pace when he is hitting on the run like that? How many pro players hit their backhands with open stances like Nadal does? Does he hit his backhand harder than his forehand, it certainly looks flatter and faster often times. Seriously, it must be so frustrating to play this guy. You have no choice but to try to be aggressive as the opponent. You hit one or even two great shots to put him on the run. Then he not only runs the ball down but he comes up with an open stance sliding bullet from outside the doubles alley seemingly twice as hard as his normal strokes. Even when guys stay back they get passed, let alone when they come to the net. I remember watching Pete Sampras dare guys to stretch him out on his forehand side, but Nadal seems to be able to do it on his backhand side as well.
