i'm really sorry for posting so much, but one of my coaches wants me to use a short bat to do top-hand drills with one hand while kneeling. it has to be short since when i choke up on a regular bat, the shaft gets in the way. i found a number of wood and other gimmicky short/stub/mule bats online but i haven't seen any aluminum ones online. but i know they exist since we used them at a clinic a few weeks ago. does anyone know what they are called so i can look them up? thanks!
