Two of my favorite Maddux stories:
Marquis Grissom once said that Maddux told him during a game to play a few steps deeper in right field when Gary Sheffield came up because he was going to make him hit a deep liner to the track. The next inning, Sheffield came up and hit a hard drive to right, and Grissom was standing there, waiting for a ball that would have normally gone over his head.
Can't remember who said it, but:
Give Maddux a baseball 60 feet, 6 inches from an exit sign and tell him to hit it. He'll ask if you want him to hit the E, X, I, or T.
The strike zone could be 4 feet by 4 feet or 4 inches by 4 inches and it wouldn't change a thing about Maddux.
