Which seems to conflict with the ruling from other sources. It also conflicts with the notion of where the ball is when it contacts a runner.
Stuff to ponder...
* Batter hits the ball into the dirt right in the batter's box. Ball comes up and hits him while he's still in the box but in the part of the box that's in fair territory. How many guys would call this a foul ball? An out?
* Batter hits the ball into the dirt in front of him. As he's running to leave the box, the ball bounces up and hits him while he's still in that part of the box that's in fair territory, but his right foot is out of the box. Who would call this foul? Who would call him out?
* Batter hits a ball that just dies in the dirt. It spins on the ground and is lying in the box in the part that's in fair territory. Batter's running to first but in so doing steps on the ball with his foot while his other foot is (a) also still in the box or (b) outside the box on the ground. Who would call this a foul ball in (a) or (b)? Who would call him out in (a) or (b)?
Decisions, decisions.
