It's sad to see him go, but 3B is the hole we can best fill with internal options. I could probably make a pretty good case for a DeWitt/Baker platoon being only a win or so worse than Aramis. Vitters, Flaherty, LeMahieu, Marquez Smith, and even Marwin Gonzalez could also be potential positive contributors, though I wouldn't project any of that crew particularly close to 3.6 WAR. The Angels might make Alberto Callaspo available fairly cheaply (and he may actually may approach 3.6 WAR). In addition, there's a few other cheaply available guys like Kevin Kouzmanoff who might be worth taking a flier on. 1B and the front of the rotation are more pressing needs, as we have no real options to fill those spots.
