With the Gross/Kielty platoon, I'd be tempted to dismiss the Ward/Salmon platoon in favor of Thames for LF, using Dunn at DH.
Honestly, I think this team may have difficulty winning games. Not much OB, particularly vs. RHP, which you will see most often, but I wouldn't have too many platoons, either.
And I think you may need another R2 RP in there to suck up innings. Correia, Bauer, maybe Crain?
Just thoughts.
