Catcher's Pitching-Situaton

You not only warmed his arm up, you burned it out for that weekend. Remember, now that they're 13 they are playing on a bigger diamond and the strain of throwing is a little bit greater. You really need to protect this kid's arm. Cathing 11 innings and then expecting him to go out and pitch was a little irresponsible on your part. I don't really have a problem with a kid doing both, my son likes to catch an inning before he pitches to get loose, but you have watch the number of innings you subject him too of this. Catching is very tiring for the player (especially if it's hot) their backs get sore, the legs fatigue, the arm is spent, etc. If you are going to play this kid in both spots, I'd come up with some sort of plan where only catches X number of innings prior to pitching or possibly pitch him before catching. But even then you have to be careful of fatigue because his tiredness will be much more evident on the mound than behind the dish. If it was my team, I'd develop another catcher or another pitcher instaed of having this kid do double duty. Maybe he could pitch and play 1B or OF to help rest his arm a bit.
