When an umpire errs, both teams are required to know the situation.
Here a bunt foul for strike three results in an out. Three outs end an innning.
Defense should recognize the third out and clear the field. No.
Defense provides the same batter with a do-over pitch.
Batter singles and a run is scored.
Coach then decides to investigate the matter.
If we overlook the bunt foul, clearly we play on and the run counts.
But if we recognize the third out and clear the field, does the run still count?
