Grant Brisbee of SB Baseball Nation has an excellent take on what the Astros should do with Wandy:
Other teams are probably aware that it it's going to take more than a #15 prospect and a Peet's gift card to pry Wandy Rodriguez from the Astros. There's no rush to deal him; Houston has all of the leverage. And if they don't find a deal to overwhelm them, they'll close up shop and open it back up next July. If that doesn't work, they'll do it again. The Astros should definitely be sellers at the deadline, but that doesn't mean they need to sell the display cases and fixtures just because they can.
