In the split second from the time the ball leaves the pitcher's hand until it reaches the plate you have to think about your stride, your hip action, your wrist action, determine how much, if any the ball is going to break and then decide whether to swing at it. ↗
I'm always amazed when a pitcher becomes angry at a hitter for hitting a home run off him. When I strike out, I don't get angry at the pitcher, I get angry at myself. I would think that if a pitcher threw up a home run ball, he should be angry at himself. ↗
