R3 Misses Plate on Walk

[dddunn3d]

Taking your play down a slightly different path:

R2 never does attempt to return to touch home, and the defense doesn't appeal. The run scores but you have yet to make a call.

Your words: By the PU having not made a call the play cannot become relaxed

So, at what point does the play relax? You may think I'm splitting hairs but the point I'm illustrating is important to 7.08(k).
