My dd has been pitching seriously for 1.5 years.she is 10.I taught her from a lot I learner on this great forum and dvds.we decided to go to a Pc.she is pitching a 12" ball around 41-42 and uses the leap n drag style.tonite was around the 5th time seeing the Pc and he noticed that around every 4th pitch she would jump illegally of the rubber with both feet airbourne.he said it was hard to notice and may not get called but wants to eliminate this issue now.he wants her to use the step style to resolve this issue.my concern is that the season starts in April and not sure if this is enough time to change styles.2nd concern is that she throws significantly slower with the step style.anybody been through this?? Any thoughts??dd is a little frustrated.thanks in advance
