The Umpire Bible website presents an interference scenario that is brought up under the base runner "confusing" an infielder:
You can think up lots of scenarios. For example, let's say there's one out and a runner on first (R1). Batter hits a weak grounder to the shortstop. Easy double-play, right? Well, on sliding into second, R1 shouts "that's three outs," and the second baseman pulls up, drops the ball and starts heading for the dugout. Well, you might say the second baseman (F4) is a moron for not knowing his situation and falling for the trick (and you'd be right). That said, it's still interference.
I understand what's being said by this, but does this situation call for the batter-runner to be out, making for a double play, rather than putting out the base runner committing the act (since it seems like he's already been forced out, per the description of the play)?
