FpCat. I have been studying I/R for less than a year so I am still learning. I reread a post that Boardmember posted and this jumped out at me. (lightblub moment) You need to read this http://www.discussfastpitch.com/softball-pitching/18064-ball-up-9-oclock-2.html#post229314. Read the whole thread. I think it will benefit you! You are at the right place to learn I/R. Awesome support on this site!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
