Bush League but it almost happened last night

I really don't know. In this particular sequence, the thing for me is how would I verify it after the fact? I'm very cognizant of verifying runners before the fact, so the chances of this happening to me are next to none, but I don't know how I would verify the DC's assertion.

But let's say it somehow happens. The one thing I can tell you is that I'm still ejecting. I don't know if I would let it stand or if I would have a do-over.

Is there a case play for, say, the defense playing the first batter with 10 on the field and getting an out? If there is, I would use the same principle.
