I would have liked to see Mez in Cincinnati in July (following a trade of Hernandez), but there is a problem with calling him up in September: he isn't on the 40-man. Dusty has expressed concern with exposing anybody to a waiver claim.
Because, you know, other teams are chomping at the bit to get Daryl Thompson or Negron.
Grandal will be in the expanded rosters, but it looks like 2012 for Mez. Barring a season-ending trip to the DL or a DFA, this is the current 40-man
