pre-game warm up

I am not sure how much a 10, 11 year old (or anyone) really has to "warm up" his arm in the pen right before a game. If he has had a good toss routine from flat ground beforehand, stretching, warms body up with sprints, agility drills, etc., before he should be ok, only needs a few pitches. Pens before a game are practice to see how the stuff is working BEFORE one gets to the mound. That lets the pitcher know which pitch will be his friend that night and which is going to work against him, this is a concept that the pitcher needs to learn, but how many different pitches does a 10,11 year old really have? Not sure why you warmed him up and then got into something else, that is something he should have done right before he took the mound. Maybe I am misunderstanding.

That's just my opinion, I am not sure whether son ever did a warm up from the mound that age until he reached the mound, he was too busy batting in the cage, tossing the ball around, running bases. I think that he just took the mound and threw the legal amound allowed for warm up.

We always had the kids warm up in the pen just before pitching. It was mostly to get them used to throwing off the mound. Some of them insisted on throwing breaking balls so they needed to do that off the mound. Same goes for the palm ball change that most of the kids threw instead of a curve. It helped to find that off the mound prior to the limited number of pitches off the game mound.

The pitches off the mound in the pen and before each inning shouldn't be as stressing on the arm as game pitches for most kids and the pitch counts from ASMI assume that there is mound throwing going on between innings and before the game.

In the end, one just needs to use some common sense and not let or make the kids throw 50 max effort pitches in the pen to warm up before the game.
