I am a bucket Dad like most of you. I have been working with my 14 yr old dd since she was 8. She works with a PC regularly. At the start of each off season , if there is such a thing, we talk to our PC on what to work on during the winter. My thought is to make sure she can throw each type of pitch with good consistency before she learns a new pitch. She throws a 55 mph fastball to each quadrant and a flip cu to all spots. We are working on the Roll over drop presently and should be game ready this spring. Am I slowing her down with this method? I have been reading a lot of the post and seeing 10 yr olds with 3 or 4 different pitches. Just wondering what your thoughts are on this. When is the right time to learn a new pitch?
