I DID NOT THROW A CURVE UNTIL I WAS 16. My dad made me have control of a circle change and throw my fastball for spots. He told me when I could hit 8 of 10 spots at 60ft then I could throw a curve. I was very mad when I could not throw a curve and get the Higher number of K's per game...But now I am very greatful because those kids who were getting 12-13K's at 13 years old are done and I am getting K's at the D1 level right now ...I TOTALLY AGREE WITH COACH MAY
