How is R3's status affected if R2 is declared out due to interference before R3 scores?

When R2 is declared out due to interference before R3 scores, R3’s status at third base remains unchanged because the out declared on R2 does not impact R3 directly. In baseball and softball, interference typically affects the player actually involved in the play, which in this instance is R2. Since R3 has not committed any violation or been involved in the interference that led to R2's out, their position is secure at third base, allowing them to either advance if the situation allows or remain there until the play concludes.

This understanding hinges on the regulation that an out for interference applies only to the player involved in the infraction, while other runners who are not implicated can continue their advancement or stay on their bases as they were before the infraction. Hence, since R3 is not involved in the interference call against R2, their status at third base is unaffected.
