batter interferance--

Whowefoolin:

From the OBR:

6.06 A batter is out for illegal action when-
(c)He interferes with the catcher’s fielding or throwing by stepping out of the batter’s box or making any other movement that binders the catcher’s play at home base.


From the JEA:

Professional Interpretation: ...The batter is obligated to avoid making any movement which obstructs, impedes, or hinders the catcher’s play in any way.

And:


A batter shall not be charged with interference for standing still and consequently complicating the catcher’s play at any base. If he is within the confines of the batter’s box, he must make some “other movement” that is deemed a hindrance to the catcher’s play before interference is ruled.
