You do realise what you just said, right?
It's possible he can stay with, or return to, the Astros. He's been DFA'd, which means they'll either trade him, waive him or release him. If he clears waivers, they can outright him to the minors. I don't imagine there are many suitors at this point.
That said, I too am disappointed that he didn't work out. I really thought he had the tools, just needed to get over the hump. Some humps are bigger than others, I guess.
