Throwing to an unoccupied base!

[PeteBooth]

can the right handed pitcher begin his pitching motion from the stretch, after raising his left foot and looking home, then step straight towards third base and throw to third in an attempt to put out the runner on second who has started to run as he lifts his front foot? If this is a legal move, why have I never seen it, especially at the high school level?

You have not seen it because it is a very difficult move.

In addition to what others have said, the aforementioned move MUST be done in ONE continuous motion. The problem with this type of move is that inexperienced F1's have a tendency to "hang" their free foot as to freeze the runners and then throw home or pick them off. In other words a "break" in their motion as opposed to ONE Continuous motion.
