I am the commish for my local Babe Ruth league, 14u/16u SB. I only have 5 teams total as we combine the 14u and 16u groups in basically just 16u. But, in my opinion, the only fair way to have an All star team is to have tryouts. For us, the manager of all the all star teams HAS to call and personally notify each player if they made the team and if they didn't, why they were not chosen. The only way to be considered for the team, after being nominated, is you have to go to tryouts. Being nominated does not mean you will be considered for the team, you have to be at tryouts also. This prevents managers from picking kids that aren't at tryouts and then parents of kids that were there but didn't make it find out.
