Can I use the wirst snap?
Although it is often thought to be faster swing racket with the snap of the wrist, face angle tends to be unstabl. Try to hit the ball using wrist snap. I was hitting the arcket face open and the ball flew in the ridiculous direction. The cause is a snap of the wrist action. Try to hit the call using tool. It becomes the racket face angle correct. RBI is determined by the batted ball direction and angle of the wrist. It is a good idea to consciousness to move the entire wrist fixed angle.
