I really hope they're planning on using Iglesias and/or Lorenzen as the closer or co-closers (ala Graves and Williamson circa 99-00) next year, if in fact they are both in the bullpen which is no guarantee. If one does go back to the rotation, the other should be the favorite as the closer.
I like Tony, but he's not a guy you feel confident bout going into the 9th inning.
