Q:  The coach believed that a batter who stepped away from home plate to avoid being hit by a pitch should be called out if that movement caused him to disrupt the catcher’s throw to attempt to put out a runner stealing third base. Is this interference on the batter? The coach’s argument was that stepping back constituted “making any other movement” in 7-3-5c. The counterarguments seem to be that the batters action was caused by the pitcher, and that per Situation 7-3-5 E in the case book, the batter is only responsible for movements after the catcher receives the pitch.

A:  The play reads the batter moved out of the way so as not to be hit by a pitch.  He is not in violation of any rules, he is allowed to move out of the way of a pitched ball ( Rule 7-3-1b), it is then up to umpires judgement if he intentionally interfered with the catcher.
