You Make The Call

[greymule]

In searching for something else in the ASA case book, I found the exact play that whiskers brought up to start this thread:

5.5-17

R1 is on 3B and R2 is on 1B with one out when B3 hits a ground ball to F6 who throws to 2B for one out, and on the relay to 1B, R2 is called for interference. R1 had scored prior to the interference occurring. The next runner closest to home is B3 who [sic] the umpire calls out for the third out.

Ruling: Since this out is the batter-runner at 1B for the third out of the inning, the run will not count. (5-5B; 8-8P)
