I don’t know if cortisone is good for you or not. But to take a shot every other ball game is more than I wanted to do and to walk around with a cons… - Sandy Koufax

I became a good pitcher when I stopped trying to make them miss the ball and started trying to make them hit it.

Well, I already have a fork ball, but it's not really another pitch. I use it instead of a change of pace. If I have a good fast ball and a good curve ball I hesitate to use anything else. But if they're not getting me by, I try to use anything I can, including the fork ball. [...] I don't know if I can throw any other pitches. I used to try the slider once in a while, and some other pitches, but since I had this little problem with my elbow it seems like only my old standby pitches don't bother me. All the new stuff, like the slider or the others I used to try, it seems like they all hurt my arm.

It was probably the worst thing that could have happened to me, getting my first out by striking out a big hitter. Because that became my pattern for five years, trying to get out of trouble by throwing harder and harder and harder.
