It ain't over 'til … Well, you know

Setting: Major league baseball game, Cincinnati at San Francisco, bottom of the 9th inning, tie game, 1 out, runners on first and third. 

The batter hits a line drive into center field, runner on third crosses plate, game over, right? Except, Reds center fielder Eric Davis is playing shallow. He charges in, fields the ball on one bounce and runs to second base and tags the base, making the base runner from first out, because the runner was lollygagging to second, because the game was over. That makes two outs. Davis turns to throw to first base. The batter who drove in the (presumed) winning run has to touch first. The batter is lollygagging to first, because the game is over. Davis is ready to throw and get the runner for the third out of the inning, which would eliminate the run, leaving the game tied and sending the game into extra innings. Davis is ready to throw to first, but the Reds first baseman is strolling to the dugout, because the hit meant the game is over.
