Chicago Cubs fan Steve Bartman.
Josh Reddick and Coco Crisp immediately cried foul claiming that Reddick was interfered with when he tried to make the catch. With a game-changing play like that the umpires were definitely going to review it.
While they were you know that the 'catcher' was spying the quickest way to get out. If he costs the Tigers a home run during an elimination game the fans would let him here it. As prevalent as violence is at ballparks these days who knows what else!
Lucky for him the reviews showed that he did not interfere with anything--and the Tigers won.
