The Slice Serve

you will not have the hip and shoulder rotation that you have in the flat serve. You will also turn your grip over a little more counter clockwise. The ball is tossed at noon, and you swing up to the ball visualizing a nail in the sky. In doing this you are trying to hit the ball on its side which generates the slice to make it kick. While the follow through of the flat serve is across your body the slice serve is going to be on the other side of your body. The feet should be stationary with a weight shift from the back foot to the front foot when striking the ball.
