Batter Interference on Steal?
With no outs, the runner on second base (R2) is stealing on the first pitch to the batter (B1). After the catcher receives the pitch, B1 makes significant movement towards the back of the batter box in order to give the catcher a throwing lane to throw to third base.
Unfortunately, the catcher also steps back several steps in order to find a throwing lane towards third base. The batter unintentionally ends up directly in the way of the throw, so the catcher starts to throw but then decides not to attempt to throw down to third base.
From the defensive dugout, this looks like batter interference (B1 would be declared out and R2 would return to second base).
The offensive coach reminds the umpire that his batter stayed well within the confines of the batter's box, the catcher never made a throw, and there was no contact between the catcher and batter. In addition, all agree that the batter did not intentionally interfere.
What do the umpires do now?
