Batter Interference

[dileonardoja]

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 hinders the catcher’s play at home base.

The comments to 6.06(c) do not mention the situation when the batter interferes after strike 3. In that case do we also get an out on an advancing runner? In the case of a double steal do we get the out on the lead runner and return the trail runner? Same thing even if the attempted putout is on the trail runner?

Where is this all cited?
