As stated by others, the hitting lineup looks really solid. Awesome for you that Wright dropped to #7 (he's top 5 in all my drafts). I like the power bench hitters ... may turn out useful if Papi struggles. I do agree with the comment that it would be nice to see young upside on your bench. And I don't think 2 Ofers on your bench helps you. I'd drop Matsui and take an infielder, if there is a decent one left. Someone like Felipe Lopez might be nice - he could be set to improve his numbers dramatically, has tremendous position flexibility, and is probably there on the WW.
I think Bills, Oswalt, and Grienke are a decent start for a "budget" SP staff. I really like Carpenter, but I'm not so big on Duch and Loshe. And after Paps, your closers are in trouble. You say you have only 2 RP spots. But don't you have any P spots that either a SP or a RP could be placed in? If not, I suppose you only need 2 closers. But you need to keep a close eye on Percival's situation. He's certainly not as bad as some other options, since at least he's the named closer for a winning team. But he's old, and TB has a number of young quality arms who could replace him at a moments notice.
