Hey all,
Did the catcher attempt to make the throw to get the runner out?
YES, HE DID: Then it is a matter of did the batter's actions, intentional or not, prevent the catcher from making a clean play in an attempt to get the runner. If interference is called and the play results in an out, then the results of the play stands, and the interference is ignored. If interference is called and the play does not result in an out, send the runner back to the last legally acquired base.
NO, HE DIDN'T: Then, unless the batter did something to prevent the catcher from making an attempt, i.e. falling into him or the bat hit the catcher, no interference.
