He is the go to pitcher in a tied game with bases loaded. He pitches hard and accurate...
The coach has been playing him also at 1B and Catcher, he is a 5'5 140# 7th grader. He bats in slot 3 or 4 and rarely sits...unless he has pitched.
Advice?
Every ball that a catcher throws back to the pitcher is equivalent to 0.5 a pitch. If he is pitching + catching they are two entirely different actions on the arm. He will probably need to make a choice at some point between one or the other. That will eventually happen, maybe sooner than later, after moving up to a regulation field. I would recommend seeking the advice of competent medical professionals, if he were to continue doing both, growth plates being an initial concern. All the best to him, he sounds like quite a kid!
