My guess is that the 'Stros will hang onto him for at least another year. I believe he's out of options and bad as he's been, someone would probably claim him if we tried to sneak him through wavers. He might rebound some next year, but I don't think he will ever be in Bourn's class.
I don't like his approach at the plate. He starts with his hands too low and too far forward, then he tries to pull everything. That's why he has trouble covering the outer half of the plate.
