baseball and softball training drills

Si-Boards 3 "solid urethane ball has excellent rebound. Sized slightly larger and heavier than a baseball. Throw hard and for a longer workout without tiring the arm. Super Bounce means you can work grounders and pop flies the wall. Train by yourself or with friends.
