bossman72,

It's really pretty much the same answer. If both runners advance at least one base (you would include the Batter if he became a runner on the pitch; e.g. a Ball Four, 3rd strike not caught with 2 out or 1B open), the Balk is disregarded. If that condition is met and a runner is put out after reaching his advance base, that out would stand.

If all runners do not advance at least one base safely (including the batter if he became a runner on the pitch), the balk is enforced, the pitch is disregarded and the same batter is at the plate with the same count as prior to the "balked" pitch.

In your original sitch, R3 is going to score one way or another. There cannot be a "run nullifying" 3rd out on the play that stands. There could be something wacky like the R3 missing home plate, and the defense subsequently executing a successful appeal, but absent any baserunning infractions, the R3 scores.

No options on this one.
