How many teams and is it 5x5? You have some good sluggers on your team, lacking speed though it looks like.
You're definately going to need some more saves on that team with only 1 guy who is a reliever hasn't been deemed closer yet (That said, defifnately hang onto Devine.) I'd look to trade one of your hitting studs for a couple of closers.
IMO some good sleepers for saves are Rafael Soriano, Dan Miceli, Scott Linebrink (if Hoffman goes down), and take your pick of the Boston reliever behind Foulke-Riske, Mota, Seanez.
