Looks a bit weak for a first-place team in a 10-teamer, although I would wager you weren't expecting Beltre to tank quite so hard, eh? (Might as well hold him at this point, by the way).
Is this roto or H2H? If roto, I say go with your closer-heavy lineup until about the end of July to rack up the saves, then dump some to save-desperate managers.
I think you're safe to sell-high on Floyd, since he seems destined to get hurt or slump. Just don't sell too cheap.
Target a slumping star destined to turn it around, like, say, Helton.
Keep an eye on Joey Gathright in Tampa Bay. If he gets a definite starting gig and gets on base, you could snag him and use Crawford as trade bait (get top-notch talent for him, though).
