Send the runner who was out to the dugout and be sure the out was counted. With only one out to start with that's two, so the run counts. No sign that the extra runner interfered with anything.
Thank the coach for the help and civility, in spite of "umpy".
Consider a DQ for the runner staying at 1st, probably not.
Never forget the play, apparently that's the case.
OK, too easy, what am I missing?
