Some of these posts about age and late bloomers mostly fail to mention coaching. If a girl has a great pitching coach and starts at 15 she could pitch in college. Conversely if a 10U player had the motivation but a poor pitching coach she could be out of the position as soon as she starts to see it slipping away. People in my area ask "how do you find a great pitching coach". I tell them to find one who has a track record of getting girls placed at the level you DD wants to play. If she wants D1 and the coach has zero girls who went on to play D1 there's probably a reason.. D2 same thing.. etc. Unfortunately people turn their dreams over to coaches who have no idea what it takes to get them there. As a parent our #1 job is to surround our DD's with coaches who have experience and know what it takes to get them where they want to go. The rest is up to the kid.
