His nearly season long nightmare of ineffectiveness seeems to show no signs of abatement.
His trade value must be at or near its low. His contract is fairly substantial (just under $4 million this season, I'm not sure of the escalation for next year).
My guess is that they will give him every opportunity to get right in 2007. If he's not back to being a major league closer caliber pitcher by around the All-Star break, then I believe that the Astros will trade him for anything they can and probably eat a large portion of his salary. By then they will want the roster spot for someone else.
