Can someone please explain to me the difference between the two subject rules? They both deal with a fair batted ball hitting an umpire or runner. For those who don't have a book handy, they read:
3. Before passing a fielder without being touched.
EFFECT: The ball is dead.
4. Before passing a fielder, excluding the pitcher and contacts a runner who is off the base.
EFFECT: Dead ball, the runner is out. The batter-runner is awarded first base and runners advance one base if forced.
It almost sounds as if 4. is a rewrite of 3. to provide more clarification, and 3. was inadvertently left in the book. Or is there a reason why they're both in the book that I'm not seeing?
