You know what happens? Somebody writes a story 10 years ago and it never changes. If the guy 10 years ago was wrong, the stories are gonna be wrong f… - Sandy Koufax

In 1960 I had made the transition from thrower to pitcher and had not understood that in making the transition I had made a beginning, not an end. you become a pitcher before you become a good pitcher. [...] Nor do I wish to testify under oath that I have not forgotten, do not—and will not—forget from time to time and revert to the wayward ways of my youth. It's usually when I'm tired or mad, but dumbness is not to be completely discounted either. In the 1965 All-Star Game I was terribly wild. I came into the game in the sixth inning and immediately threw seven straight balls. Although I got out of the inning, it was a struggle with every batter. [...] There was not a thing wrong with my arm. My arm was fine. My head was something else again. Knowing that I was only going to pitch an inning or two, I had thought, "Well, hell, I'll just go in and throw as hard as I can." And there I was, right back where I'd been ten years ago, wild high.

The only time I really try for a strikeout is when I'm in a jam. If the bases are loaded with none out, for example, then I'll go for a strikeout. But most of the time I try to throw to spots. I try to get them to pop up or ground out. On a strikeout I might have to throw five or six pitches, sometimes more if there are foul-offs. That tires me. So I just try to get outs. That's what counts — outs. You win with outs, not strikeouts.

People who write about spring training not being necessary have never tried to throw a baseball.
