So I've heard this a few times from some great tennis minds, even some on this forum. That when you want to hit that winner, high speed, still topspin, low trajectory winner, to make your grip more western and have the racket face closed a little bit more on contact. It will be a fast forehand, but stay in because of it already being low and the topspin. It looks to me like Djokovic does this. Does anybody intentionally tilt the racket head slightly closed at the point of contact when ripping into a forehand winner? Or not fundament in your opinion?
