"Working on spins"

Here is a great way to check to see that you are spinning the ball correctly on all of your pitches. Take a regular softball and tape a line around the ball across the seams (cut the loops in half or across 4 seams) with black electrical tape or draw a 1" wide line on with a permanent marker. Then watch to see if your fastball and dropball spins are straight over the top, if your curveball and screwball spins are sideways, and if your riseball spin is backwards. It will help you determine what release or grip will give you the best spin and make the ball move properly. ~ Jim Greiner - Doom Pitching Coach
