				It would seem to be a judgement call,
			 
 
			
			as to whether the batter-runner actually interfered with the ball or the play.
 The case book cites kicking, but caroming off the side of the leg (for example) I wouldn't consider "kicking".
 
 If the ball is further deflected away from the catcher, I agree that would interfere with the catcher making the play. But contact could actually even benefit the defense, by keeping the ball from rolling even further away.
