Nah, it's still early. I'm sure they're still looking for another bat. If not, they better at least see if Pence and Wood can produce at the big level (maybe give Luke Scott another shot). I don't mind if Ausmus and Everett aren't producing at the plate because their defense is top notched. However, when Ensberg and Lane (who's now demoted) aren't producing, that's just too many non-producers. Berkman, Lamb and Burke can only do so much.
Oh, and the jury's still out on Wilson. He's not hitting homers like he's supposed to, but at least he's hitting for average.
EDIT TO ADD:
The Astros managed to make this upgrade ...er strategy --
