Never seen it...and hate wristbands...Pitcher tells the catcher to start on a different pitch each pitch, or guess what she wants, or you pick.My question was specifically about a pitcher who was initiating the pitch call herself, and how she communicated it to the catcher.
If pitcher shakes go to the next pitch, or rolls the ball/glove change location. (or something like that - need to mix that up)
DD will tell catch to go heavy on outside FB if that's what she's feeling...or if they're jumping all over the heat, she'll tell catch to go heavy off speed.
Coach interjects occasionally.
After each inning, talk about it.
Rinse. Repeat.
