My dd has been working hard on her front side resistance(as some of the members suggested)and as a result her speed has increased. Her fastball recently been clocked on average 53-56 mph(a few were 60 but not enough to say she pitches 60) and her drop ball was 47-51 with the changeup 38-43.I know these number may not be perfect but it does gives her something to use for comparison as she progress. The problem she is having is pitching high and sometimes she pitches too far inside(for right handers)which she prefers pitching inside. She also pitches to the other corner but she normally hits the outside corner(right hand batter).
