The solution depends upon your catcher. ?If a catcher has game sense, she can call pitches, make defensive decisions, etc. ?If she doesn't have game sense enough to do that, she probably shouldn't be playing such an important position to begin with. ?I started learning where to call pitch locations when I was ten years old, and by the time I was fourteen I could call locations, different pitches, and defensive plays.
As for a mother/father spending time and money on pitching lessons, etc, what are you paying for if your girl isn't learning how to play the game? ?Who cares if she can throw a certain pitch if she doesn't know why she's throwing it? ?That seems to me like teaching someone to breathe but not telling them why they have to do it.
And. ?A coach is just as liable to make a mistake with a call as a player is. ?A coach often doesn't have the perspective a catcher does, as a catcher can see the whole field, and more importantly, where the batter is in relation to the plate, etc.
That's just my bit.
