Good luck! Just a heads up that moving up to 12U and a 12" ball at 40' is a big adjustment, so do not become frustrated if things do not go well. My DD got shelled by a couple of older 12U teams that stayed down in the fall.
update on my DD... she didn't pitch in the first game...had a couple rough at bats tears at the plate and all...so I thought second game she wasn't gonna get to pitch..but 2nd ining the HC had his DD (#1 pitcher and one of the catchers on the team) take my DD and had her warm up and she pitched the last 2 innings of the game! had more walked batters than we would have liked but she did get a strick out and she got some good hits of of her pitching...ill take that for now....the smile on her face after striking out that one batter mad all the hard work and tears worth it!! couldn't have been more proud..
