Oswalt Wants Out! First Choice Cardinals?

Oswalt is under contract for $15 million this year and $16 million in 2011. The following season he has a $16 million team option or a $2 million buyout. Despite the 32-year-old's stellar track record (3.21 career ERA), his pricetag will obviously scare off a few teams.
the potential trade destinations that interest Oswalt are St. Louis, Texas and Atlanta. But if he's requesting/demanding a move, then presumably he's open to other options. Considering the abysmal run-support situation in Houston, Oswalt's fantasy value is almost certain to increase. I tend to think that Oswalt will stay out of the AL. I would love to see him lay for my home team but I think the Astros may not want to tade him to the Cardinals. I guess we will see what happens next,
