Does it behoove the B/R...?

[professor]

First and foremost you must agree that the ball remains alive after the 3rd out is recorded. Therefore, it is compulsory (sic forced) for a B/R to reach 1st safely and all other forced runners to advance safely for a run to score with 2 outs. If after 3 outs, the defense appeals that a runner never reached a base safely (first), the B/R sould be declared out and no run scored. The fact that in 99.9% of cases like this, an appeal would never be made, does not negate the fact the the B/R is out if appealed for the 3rd out which supercedes the original 3rd out
