@Comp. I agree in all cases the requirement for a quality throw still would apply. I didn't see the play, have no idea if throw to RF was air mailed or if the 1B could not field it because of the RETIRED BATTER. But, referring back to the OP under no circumstance I can see would a R1 be returned for any reason. If no interference the ball is live. If interference called, R1 is also out.
