^^^ this. Just like the pitcher who fields a ground ball or line drive.

The umpire must judge that the pitcher is no longer acting as a fielder, but is now taking the position of a pitcher.

I would strongly encourage the umpire to be very deliberate in making that determination and giving the runner(s) an extra heartbeat or two to react by returning or advance to the base prior to enforcing the LBR.
