Pulled foot mechanic and timing

[refman]

Back to your original scenerio......I disagree with the explanation of a couple posts. I think you make the out/safe call based on which arrived at the base first. If the ball beat the runner, call him/her out. You don't take the possible pulled foot into consideration at all. Now if the first base coach or even the manager sitting in the dugout thinks the 1B came off the bag and requests you ask for help, fine....ask. If the PU saw the pulled foot, do the right thing and change your call.
