I'd be a bit careful on Ledezma, he's a solid pitcher, but with all the Tiger's bullpen woes (Rodney falling apart, ZUmaya a head case as always, and, as we in the D like to call him, roller coaster Todd Jones doing his normal up and down thing) he is starting to be used in unfavorable situations as opposed to the long relief role where he dominates.
As for your lineup, I'd look to package Sexton in a trade for a better 1B and move Cuddayer into the outfield over Tavaras. Maybe move Sexton with Hughes for an upgrade if he starts off hot.
Also, I actually like Barrett pretty well at C. It'd be nice for you if you could find a way to move Tejada into SS and get a solid util replacement off WW.
If you can,
