No, this isn't about Javy coming back.

I think most of us know that the 25th man on the team right now is only here because they're left handed (Harris, Costanzo). Until Rolen gets back (or even after, although it'd be hard to see who they'd get rid of), what about bringing up Navarro as your 25th man. He can be your lefty off the bench (actually a switch hitter) and what actually makes him useful is it opens up Hanigan or Mesoraco to PH on their days off.
