Head coach Tim Corbin uses the ATEC Casey Pro 3G training machine to run his catchers through a series of blocking drills, rapid-fire drills, and block-and-recover drills for catchers at this Vanderbilt Commodores practice.
Catchers are great, just one thing I recommend especially seeing none wear a throat piece on the mask, but they should tuck their chins like into their necks, or close because if a ball comes up and hits you in the neck it will hurt. (Except for the rapid block so they can keep eye on machine/ball)
