Bases loaded, 3-0 count, next pitch ball 4, R3 as before misses home plate.

R3 continues towards his dugout, a good 80' away from the plate, and is just two steps away from entering. At this time one of his teammates shouts to R3, "They're appealing you missing home!" R3 turns and observes that F1 has thrown the ball to F2; the ball is about half-way to home. R3 then starts to run back to the plate. Before R3 has traversed even one-third of the distance back to the plate, F2 has secured the ball while touching home, and asks for the appeal.

Is this a legal appeal or does F2 have to tag R3?
