What's the call?

[UmpJM]

bmiguel,

If the runner on 2nd (most commonly referred to as R2) misses 3B and the runner on 1st (R1) scores behind him, the defense has the opportunity to nullify R2's run and obtain an out by executing a properly constituted appeal of the R2's miss of 3B.

As described, there is no opportunity for the defense to obtain an out on the R1, nor have him "returned" to any base. R1 did NOT "pass" R2 because of the fact that R2 missed 3B.

Once R1 scores following R2, R2 has lost the opportunity to correct his miss of 3B.

The only affect that R2's miss could possibly have on R1 in this sitch is if the appeal of R2's miss of 3B was the third out of the half inning. If it was, R1's run would be negated per:

7.12
Unless two are out, the status of a following runner is not affected by a preceding runner’s failure to touch or retouch a base. If, upon appeal, the preceding runner is the third out, no runners following him shall score. If such third out is the result of a force play, neither preceding nor following runners shall score.
