Last out of inning

[Bluefoot]

Doesn't anybody read the rule book? (Just kidding)

POE#1 APPEALS
M. Fourth Out Appeal. (2005, page 133) An appeal may be made after the third out as long as it is made properly.

The play described in the original post is a proper live ball appeal. (wait, keep reading, same page, but go up to letter...)

J. Force Out. If an appeal is honored at a base to which a runner was forced to advance and the out is a force out, no runs would score if it was the third out.

So, my conclusion A.) putting these together, the live ball appeal at 1B is allowed as the "fourth", or new third out, and thus the force at 1B neagates the run.

Or is it conclusion B.) Does the third out made by F6 on the runner in the rundown eliminate the force on the BR, and thus, the appeal is no longer a force out, and the run does score?

I go with my "A" conclusion. Run does not score.

Good question and making us think, Mike.
