Pretty advanced thinking. I waste little time. I just couldn't help it. I change him up again. This time even slower, with a bigger arc, and a louder groan.
Time slows way down.
His right elbow rises and his left foot starts forward. Part of the experiential reality of pitching is watching the batter's eyes. Remember, now, that all this stuff is happening pretty fast. Even at 85 MPH the sphere takes less than a second from hand to the plate, but in that time lots goes on. As soon as I released that ball, he had the look.
