It came to me in a dream

[DG]

"On the other hand, if a batted ball goes through or by an infielder (other than the pitcher) without touching the fielder and then strikes a runner immediately behind the infielder, the umpire must determine if another infielder has a chance to make a play on the ball. If the umpire determines another infielder does have a chance the runner is out. If the umpire determines another infielder does not have a chance, the ball is alive and in play".

Are you saying that if a runner is struck by a ball behind infielders but not immediately behind an infielder he is out? If so I have never seen or heard that interpretation so new one on me.
