MD,
I agree totally let them play where they want! However this affected us last year as we were looking to play up at 16U, while we were a 14U team and were told that we would then be locked in to play 16U for ASA Easterns or ASA Nationals. So be careful what you play in an ASA sanctioned event if your planning on attending Their Nat's. Play up in another sanction such as NSA or USSSA this will not affect your ASA status.
