Correctable Error?

I think mcrowder has something here.

What was the count to B1 at time of the balk? I think the next 2 pitches should go onto his plate appearence. B1 is still the proper batter because 6.04 A batter has legally completed his time at bat when he is put out or becomes a runner. Therefore, B1 hasn't legally completed his time at bat.
If either of those pitches legally complete B1's plate appearence (while B2 is in his place) we have BOO by 6.07(a) A batter shall be called out, on appeal, when he fails to bat in his proper turn, and another batter completes a time at bat in his place.

But if the infraction is not picked up before the first legal pitch to B2, then B2 is the new proper batter by 6.07(c) When an improper batter becomes a runner or is put out, and a pitch is made to the next batter of either team before an appeal is made, the improper batter thereby becomes the proper batter, and the results of his time at bat become legal.

Finally, my 2 cents on the TD, stay in the stands. It's not your job to head off possible problems and in this case, possibly stop the defense from gainig an out by appeal.
