Passing a runner

[greymule]

In ASA, the moment the batter is put out, all force plays are removed. Also, the moment a following running is put out, the force is removed on all preceding runners.

(This is not as simple as it sounds. It does not always hold, for example, in OBR. The difference can affect whether appeal plays on missed bases are force plays.)

Of course, runners still have to tag up on fly balls, even if the batter-runner passes someone on the basepaths before the ball is caught.
