On May 18, 1957 — Dick Williams of the Baltimore Orioles hits a 9th-inning, game-tying solo home run off Paul LaPalme of the Chicago White Sox seconds before 10:20 p.m., the curfew set so Chicago can catch a train out of Baltimore. If Williams had done anything else, the White Sox would have won. The game is later replayed from the beginning and Baltimore wins.
