Question about Rule 8.01© as it relates to Rule 8.05(a) At what point does a movement become a pitcher's natural pitching motion and commit him to the pitch?
I was talking with fellow umpires at tournament this past weekend about the differences afforded right and left handed pitchers regarding these rules in their pick-off moves to first base, and third obversely). In both scenarios the free foot does not break the plane of the rubber and there is no interrupted motion, so those are not issues. Are these the correct rulings?
1. A left handed pitcher is allowed to lift his free foot, even to the point that the thigh is parallel to the ground , the same initial motion as his natural pitching motion, and then throw to first. (no-balk)
2. A right handed pitcher is not allowed to lift his free foot and throw to first, he must use a "spin move" thus jumping with both feet at the same time. If the right handed pitcher lifts the free foot but not the pivot foot (even though there is no motion toward the plate) it is considered a natural pitching motion and thus a balk.
My argument is OBR only states that a natural pitching motion commits the pitcher to the pitch, and that the pitcher must step ahead of the throw. It is impossible to step and throw without moving the knee and lifting the free foot from the ground. OBR makes no mention or requirement of a "spin move." Why would we allow the left handed pitcher to start with their natural pitching motion then throw to first and not the right hander? In my mind it is about the intent to deceive and where the free foot lands. Left handed pitchers are clearly trying to deceive the runner when they lift the free leg like they are going to pitch then throw to first and right handed pitcher isn't fooling anyone by simply stepping and throwing to first.
