Jayson Stark posted the last trade deadline Rumble, in which he breaks down the destinations/intentions of players and teams.
On Brett Myers:
Once Roy Oswalt and Lance Berkman were gone, the Astros told teams they would listen on Brett Myers and Wandy Rodriguez. But the price wasn't a whole lot less than they'd asked for Oswalt, and they were firm that they weren't eating any more dollars. So it would be an upset if either pitcher gets moved before the deadline.
"Weren't eating more dollars?" Myers makes a little over $1m for the rest of the year. Wandy is owed around $2m. Eat the contracts if you have to, just get some prospects for them. I feel like I'm taking crazy pills!
