Lugnuts had the bases loaded with 2 outs, tied in the bottom of the ninth. Batter hits a groundball single, but Nessy(who was the runner on 1b) stopped running to 2b and turned around to join the mob of celebration. CF picked up the ball and ran to 2B with it, therby ending the inning with a force out, so the run didn't count, then the away team won the game in the 11th.
THey had to point it our to the umps, who then had to confer to make sure it happened like that, who originally ruled that the run stands because the runner crossed the plate first ending the game (which of course is wrong in a force out situation) then they had to go into the Lugnuts dressing room and bring them back out onto the field to restart the game.
