If R2 misses third base while advancing home after a fly ball is caught, what is the result when the defense appeals?

When R2 misses third base while advancing home after a fly ball is caught, the defense has the right to appeal the missed base. This is a critical situation because the runner's failure to touch a base can lead to the runner being declared out upon a proper appeal by the defense.

In this case, the correct result is that R2 is declared out, nullifying his run. According to the rules of baseball, a player must legally touch all bases in sequence when advancing, and missing a base is a violation. When the defense appeals this infraction, the umpire assesses the appeal and if R2 indeed missed third base, they will declare him out. This action not only eliminates R2 from the play but also means that his attempt to score does not count.

The other options do not accurately reflect the consequences of such an appeal. The first option incorrectly suggests that the length of the fly ball influences the ruling, which it does not in this context. The third option inaccurately states that R2 can stay on base when he has not legally completed his advancement. Lastly, the fourth option incorrectly asserts that the run counts due to some sort of force play, which is not applicable here since the player is out for not touching a base
