7. Moises Alou

Signed as a free agent before the 2002 season, the career .303 hitter helped the Cubs win the division in 2003. His best season on the North Side came in 2004 when he batted .293 with 39 home runs and 106 runs batted in. His reaction to Steve Bartman catching the foul ball over Alou's glove in Game 6 of the 2003 NLCS will be replayed forever. (Jonathan Daniel/Getty Images)
