i have read that you should show your change up during warmups to get them thinking? i know our coach has a panic attack if he's see's a change up.. he stops the 9 and 10 yr olds getting into the batters box and tells them LOOK OUT FOR THE CHANGE UP !!! which works out really good after the 9 yr old strikes out. they come over to me to ask, "what's a change up"? any thoughts about showing it in pre-game warm ups ?My 99 told us recently that she tries not to throw her other pitches (change up and curve) when warming up. She only throws the fb so that the other team doesnt see what she can do. This is no instruction from us as parents or her pitching coach, just something she has recenlty started doing. So I guess she plays "possum". Not that she has much to throw at this point, but her mentality of the game often surprises me at her age.
