Greymule's posting said "However, if after the tag, F5 still had time to get the BR at 1B, he could have done so for a fourth out and nullified the run." That is NOT an appeal play, so your quote of OBR 7.10 - and all the other manual pages - is irrelevant. He's saying in his "however" - unless I misunderstand, and he wants to clarify - that the defense made the equivalent of a 5-3 play for this 4th out.

That's right. The defense made a 5-3 play for the 4th out. I agree that this would not be an appeal. It's just a 5-3 out. However, I think there was once (quite a while back by now) a question about this, and it merited an "approved ruling" or something.

Please tell me that teams, noticing a BR has stopped running to 1st in this sitch, throw to F3 to claim an appeal of a "missed base," or try to say the last out is a force, and thus the run doesn't count.

I'm not quite sure what you're getting at here. If the defense threw to 1B in time and got a fourth out before the BR arrived, no runs could score on the play. Since I had injected softball earlier, I will say that in ASA softball, the defense cannot get this out at 1B if there are already 3 outs.
