Has the B/R interfered simply by virtue of getting hit after being retired?
I ruled no intentional interference, run scores, 2 out.

Running lane is not a factor on a throw from F3 to F2. If the BR was simply running toward 1st, probably a good call. To quote IRISH, "she can't just disappear after being retired."
