Situation at a friendly yesterday. Umpire ruled one way - then changed his mind.
Runner at 1st, 1 Out. Hitter hits a low line drive - 2nd baseman one hops it and throws to 1st for the putout (so - Batter/Runner is now out at 1st).
HOWEVER - the runner at 1st mistakes it for a catch and returns to 1st thinking she will get picked off at 1B. Runner stays at 1st after being told no catch was made. Ball returned to the pitcher. Defense then proceeds to throw the ball to first and 1B tags her. Is the runner that returned to 1b safe or is she out?
