The new coach understands she is not going to quit old team and says staying with them is the right thing to do. Old coach doesn’t know yet I am going to tell him at next practice. New team is much better and plays in bigger better tournaments. So this move will be good for dd in the Fall. Old team is C class and I’ve heard parents around fields saying “that pitcher was pitching for a team in A class last weekend so she can’t pitch for this team in C class”. This is main reason for me starting this thread. Is there any truth to this.
It depends. ASA, PONY, USSSA, PGF all have different rules. When DD was younger, she played on her town travel team (which is classified as B/C) and a club team classified as A. Because she was rostered, she could not play in any of the town travel tournaments of the same organizing body (i.e. ASA). Guest play may/may not be different. There are Add/drop rules, etc.
It will usually only matter if either team is going to Nationals as she could be prevented from attending if deemed to be rostered and not just guest player. The organization body directors will be the ones to ask, just to be sure.
There is nothing wrong with picking up with another team as long as she's keeping her commitment to the current team until the season ends.
