The idea came to me in a game, when the guy at bat was all tighted up waiting for my fast ball. I knew he'd swing as soon as I just barely moved. So when I stretched, I paused just a little longer with my arms above my head. Then I threw my left foot forward but I didn't come around with my arm right away. I put that foot of mine down, stopping for a second, before the ball left my hand. When my foot hit the ground that boy started swinging, so by the time I came around with the whip he was way off stride and couldn't get anywhere near the ball. I had me a strikeout.
