OK, slight hijack (to the only active thread

)
The ol' obstruction call:
Say, in that prolonged rundown, runner is obstructed going toward home, maybe 10' from the plate. Might've been tagged out at home regardless (by the back-up fielder).
But, runner reverses direction, a few more throws back & forth, eventually tagged out by a hair sliding into 3B.
HTBT sure, but generally, with that sort of continuous rundown, are we protecting the runner to the bag where they finally get tagged?
