Chicago Cubs (2003)
Steve Bartman became the most notorious man in Chicago as he left the Cubs with broken hearts. The team was cruising toward the World Series but the Marlins pipped them at the post. Bartman was sitting in front row seats when the ball came flying toward him. He reached for it but this prevented Moises Alou from making the catch.
Poor Bartman inadvertently distracted his team’s player and this was a major turning point. Chicago regained momentum and they fell apart. Security escorted Bartman from the stadium because he received abuse and a barrage of trash thrown his way. In 2016, the Cubs sent him a World Series ring as they achieved redemption (via NBC Miami).
