Steve Bartman and the 2003 National League Championship Series
Without question, “Steve Bartman” is a name that will forever live in infamy in Chicago sports lore. In the 8th inning of Game 6 of the NLCS, the Chicago Cubs held a 3-0 lead when outfielder Moisés Alou pursued a ball near the left field fence. But in his zeal to catch a ball in a game, Bartman reached for the ball, deflecting it away from Alou and costing his beloved Cubs an easy out.
The opposing Florida Marlins would actually go on to score 8 runs in that same inning, defeating the Cubs by an 8-3 score. Bartman was so badly ridiculed for costing the Cubs a win and an eventual spot in the World Series that he had to move away from Chicago and legally change his name.
