In OBR and Fed, R1's miss of 2B was a force when he missed the bag, so it is a force play on appeal. Therefore, appealing the non-force miss first (BR's miss of 2B) and then the force (R1's miss) for the third out would nullify the run. The reverse order of appeals would not.

In NCAA, R1 was forced at 2B when the play began, so the same order of appeals would apply.

In ASA softball, just to show that another code views this differently, once the batter is put out, all forces are off. So there would be no way to configure both appeals to nullify the runs.

I know, because I get this play two or three times a week.
