Do you allow the appeal?

[dash_riprock]

Here's a good one from the other forum (simplified a bit):

2 outs, R2. Batter singles, R2 crosses but misses the plate just before the batter is thrown out at 2nd for the 3rd out. R2 then comes back and touches the plate. The defense appeals.

The choices (unless someone comes up with another one):

A. Score the run! R2 "scored" on the time play when he crossed the plate. He corrected his baserunning error by touching the plate, therefore the appeal is not allowed. Any appeal would have to be made before R2 touched the plate.

B. Take the run off! Since R2 didn't correct his baserunning error until after the 3rd out, his run does not count.
