I have worked with my daughter on pitching since she was 10 years old. She was two time All State in High school, Conference player of the year, Female Athlete of the year, and played on the North Carolina ASA State championship team in 05, and now she is playing softball in college. I have helped her to learn the rise, curve, curve-change, drop, drop-curve, change-up, knuckle ball and screwball. I work for many hours on this tool, trying to get the right angel on each pitch and yet keep it simple (without having to change any parts), portable and affordable. I believe this tool can help all pitchers at all levels. I don’t think you can find a better training aid that you can take anywhere and use by yourself to improve your mechanics and ball spin. I am a full time minister so I don’t have the time to work with all the girls that call me for help on their pitching. It has always made me feel bad that I could not help these girls to improve. But now I can through the Practice Pitch. It is the greatest feeling to hear how this training aid has helped girls improve and gain self-confidence.
