I was watching a college came awhile ago, and an interesting play manifested: Slapper lays down a drag bunt. She comes out of the front of the box (as slappers do) and is taking a direct/angled path to first base, so she is in fair territory running towards foul territory. Catcher fields the bunt, throws towards first, and drills the runner right in the back. The runner made no attempt to impede the play, she was simply sprinting the most direct path towards first base. Umpire rules the runner out for interference since she was in fair territory when hit. I know that there is something with the "running lane" to first, but I thought something just recently changed with that? I'm not sure.... Conversely, what would happen if there is a runner on 3rd base, and the first baseman fields a hard hit grounder and goes home? If the first baseman drills the runner in the chest with the ball, would the runner at home be out on interference?
