It's been 10 years since Game 6 of the National League Championship Series between the Chicago Cubs and the Florida Marlins in 2003.
However, Cubs fans will never forget that day.
With Chicago ahead in the eighth inning and only one win from reaching the World Series, Cubs fan Steve Bartman interfered with a foul ball that was Chicago outfielder Moises Alou was ready to catch. Instead, Alou couldn't make the play and the Cubs gave up eight runs in the inning, losing the game and later getting eliminated in Game 7.
