without seeing her play it's hard to say... concerns would be - you say a competitive team... you say the coach say will be sitting the bench to grow... as a pitcher how many older girls are there that pitch? How do they compare to her? Is the coach only in it to win games or develop young ladies in learning the game....The parents of the other pitchers that are older can the coach deal with them because I can assure you the older girls mom and dad are going to be watching if there daughter is not pitching and younger girl is getting a little time .... I agree with frozenrope circle time is precious and she needs game time in the circle.. Now she may be able to get that tim we don't know because we don't know the coach the team and your daughter. You have to decide that. May I suggest you go about it with a open mind. Don't get hung up with her playing up. Go about it without being her dad and really look at is she ready. Honestly is she ready. It's ok if she isn't and need to play another year at 10.... are you able to take that your daughter is sitting the bench and not playing even when it gets later in the season, which she might be. If you have any doubt go buy your gut... don't go by your pride (my daughter is on a 12u team)
