Hole in outfield fence at the base of the fence.

[Klokard]

From the time the F8 threw his hands up the BR and all runners should continue running. BU goes out and checks status of ball. If found to be lodged or out of play, runners return. If ball is found to be in play OR reachable (dependant on MATP) runners get what they can. If fielder throws up hands and continues digging, continue out but allow runners to continue. I have actually had an F7 do this in a game on a field that had shrubery on fence. While hussling out there, I saw him try and stuff the ball back into the shrubs.
