in high school the coach gives me the signal and i give it to the pitcher. she might shake it off. In the 18 & under league I call the pitches.
In your honest opinion, do you think you are just as capable of calling the pitches as your high school coach? I would think that an experienced catcher should be more than capable by the time she is in her early teens? Let the girls play the game. Its probably more fun for you too!
