Scheepers slice serve.



It seems she employs pistol grip. Around contact, image 11, her arm and longitudinal racquet axis form straight line. As a result, arm pronation contributes nothing to RHS. I believe this is very bad technique.

This is flat serve.



Wrist ulnar deviation is locked, so the player doesn’t produce side spin.

There is question. How is he able to lock ulnar deviation? Answer – He utilizes hammer grip. His arm and racquet cannot be in straight line position and he can use arm pronation to maximize RHS.
