If a RHP's windup usually consists of him stepping to the side with his free-foot, is there a good rule of thumb for distinguising between the start of his windup and his stepping to throw to first? I mean, even if his foot isn't turned and pointing towards first base, it seems that he would still be able to argue that a step to first base. It's like he'd have the option to throw to first or pitch with the same movement.
