Ending Game

"It is not a force out; it is a base award. At best, the runner is out for missing a base on an awarded base, but it is not a force out."

But it is a base to which the runner is forced, regardless of whether it is an award. Isn't this a similar play:

Bases loaded, two outs, B4 hits a grand-slam over the fence. R3, who started on 1B, misses 2B. After everyone has crossed the plate, defensive fielder appeals that R3 missed 2B. How many runs score? None, because the runner missed the base to which they were "forced." All of the runners were "awarded" home on the ball hit out of play on the homerun.

So how is the OP any different? Are you saying that because I can't throw the ball to 2B to retire R3, and it is an awarded base, it is not possible to have a "force" on an appeal?
