I have an 11 year old team and my pitchers and catchers do all the pitch calling. They don't have too many pitches to call other than a fastball and change, depending on the pitcher, so they work on calling their spots too. We teach them what to look for in the batters, the stances, the swings, the count, what the pitcher has that is working, etc... If you teach them young they will pick it up like any other skill. It is like those coaches that don't go for double plays because they are afraid they will overthrow. Teach them to do it, practice it all the time and they will not overthrow, it will become a routine play. Not giving them the opportunity to try it because you don't want them to mess up just takes away from them learning the game. Why not let them be the best players they can be?
Haven't we talked about this once or twice before??
