My oldest was a pitcher. Did this ever happen? Yes ~ we had one pitcher go south really quick and the back-up get hurt. It was not a usual experience, so we put it down to a "it happens" situation. I do not agree with it happening several times over the course of the season, however, as appears to be here. One thing that I would suggest (to keep your daughter safe and to grab the bull by the horns, so to speak) is that, before each game, she and the other pitchers ask for the pitching plan. This is a good time for her to learn to check if she needs to be warming up before the game in case she is needed. I realize she is 11, but this is an important tool. By 14U, none of our pitchers waited on the coaches to be told when to warm up, etc. They asked what the plan was, knew to get their throwing/batting warm up done first with their catchers, and then went to warm up for pitching. If they were the #3 for the game, they didn't warm up as much but they made sure they were at least loose in case they needed to go in.
