the first thing that jumps out is that you need some steals. i dont know who to trade or who to trade for, but that would be my first concern.
you could maybe get someone like Willy Taveras fairly cheap and he could steal ALOT this season in CIN. just an idea.
second thing that jumps out to me is saves. i think you need one more reliable closer who is likely to get 30+. Cordero can get saves, but theyre not pretty. Sherrill is someone i wouldnt count on holding that job all season. if he pitches like he did in the 2nd half (6.59 ERA/ 1.76 WHIP) then he wont be closing for very long. hes probually better suited for LH specialist. the Orioles have Chris Ray back and he could be someone to take over for Sherrill. Corpas if he ends up closing in Colorado could be a plus, but id still look to get another more reliable closer.
