I was getting ready to say it was OK, until I found out it was in 1 day. So, how many times did she warm up? Add those to the pitch count. And did she throw 5 warm up pitches, each inning? 5 pitches X 5 innings X 3 games = 75.
Ideally at 10U the team has enough pitching or is working on developing enough pitching that one kid doesn't need to throw 208 pitches in a single weekend.
What do you do if there is enough pitchers but the coach is only developing one of them, using her for 7 games and giving the other pitchers 3 innings total all weekend long? 10U is the age group.
