It might be a dead ball, if the ball bounces off the batter's helmet and goes into the dugout or over the fence. I actually had a play a few years ago where the catcher's pickoff throw hit the batter's bat (she did nothing to interfere), and the ball went over a shortened fence in front of the third base dugout. At the time, there were runners at second and third, so the catcher's bad throw cost her team two runs.True enough! I thought you were saying it would be no interference but dead ball.
