Thanks for the help PGStaff and BillBill.
As for not being a "late bloomer" -- he hasn't ever played summer ball, so he is not as well known as kids who have played in competitive summer leagues for years. I keep telling myself that the good thing about him not making "all stars" when he was playing LL is that because he hasn't played year round baseball, he has had the chance to do other things (like golf and football) and still loves baseball best -- and he hasn't had the opportunity to get either burned out or worn out yet.
The bad thing is that he loves it, and really wanted to play all those summers, and he really needs to play this summer if he wants to improve, but we don't know how to get him on a team.
