Vitters has been placed on the DL at Triple-A Iowa with a broken finger, MLB.com's Carrie Muskat reports. Given how little time is left in the season and how poorly Vitters is playing - he's hitting .213 in 112 games with Iowa this year - he may have played his last game as a member of the Cubs' organization. A first-round pick by the Cubs in 2007, Vitters has only played 36 games at the big-league level, hitting .121 in 2012.
