Fed: 2-28-3 Time of Pitch

Perhaps I should attempt further clarification. We've all seen the lefty, who, after coming to a set position, raises the forward leg (non pivot foot) straight up in the air and his arms are in motion upward. I believe that what constitutes commited to pitch, is if any motion towards the plate/batter is present, then, presumably, if he then attempts a pick-off he has committed a balk. The question is what defines the point in his motion when he can no longer throw to or fient at a base without balking?

In answer to your question - It's umpire judgement.

FED rule 6-2-4(b)

Failing to step with the non-pivot foot directly toward a base (occupied or unoccupied) when throwing or feinting there in an attempt to put out, or drive back a runner;

What you are referring to is better known as the Lefty Balk move. One of the best pickoffs if not the best in the game today is Andy Petitte of the Yanks.

Side Note: Whenever a coach starts to complain about a Lefty who is picking off his / her runners is: "hey Coach get yourself a Lefty"
