Moises Alou

After the Chicago Cubs blow an opportunity to reach the World Series in 2003, Cubs fans blame the team's misfortune on fellow fan Steve Bartman, who interfered with a foul ball and prevented Moises Alou from making a catch.

The 1994 Montreal Expos were arguably the best team in baseball, and the only Expos team in their history about which that could be said. Then came the players strike that led to the cancellation of the postseason and the Expos' first chance to bring home their first championship. What followed was a painful decline that saw financial troubles, ownership by the other 29 teams, and finally the move to Washington.
