For clarification (and my continuing education), can someone verify that the rule states that batter cannot "re-establish" his position so as not to potentially trigger BI. I will admit I have not searched this out and always assumed it was a judgement call without much definition as to what constitutes BI and what does not. Assuming batter does not move horizontally, is he required to squat down or at least not stand taller once C receives the pitch? On a suicide squeeze, assuming a successful bunt from a right handed batter, can the batter start down towards first if he blocks catcher from potentially fielding the ball? Should he bunt and then stay put?
