Till she is in 14U, she should lean towards more innings. If she is a 3rd or 4th pitcher in an A team, she is not going to pitch against the best teams, they will use their ace. Young pitchers need mound time so they can develop. Sitting on bench will not do any good to a pitcher. When she goes to 16U or 18U and hopefully committed to a program by then, she need to look for a team that will play tough competition.
