ASA Look Back Rule

[Dakota]

One more time...

The LBR goes into effect when the pitcher has control of the ball in the circle and is not making a play (and BR has acheived 1B). A runner moving may continue to move and is allowed one stop. After the one stop, the runner must immediately move to the base of her choice without another stop. A runner stopped must move immediately, also, to the base of her choice without stopping again. There is nothing - NOTHING - regarding one runner moving that removes the obligation on another runner to move immediately once F1 is no longer making a play.

As Mike said, as a practical matter, F1 is not going to just stand there while a runner scores. But if she does, and if R2 also just stands still watching the other runner score, R2 will be out on a LBR violation.

R2's obligation to move has nothing - NOTHING - to do with R1 "completing her play."
