Think its more than a little surprising teams like Baltimore, KC, Oakland, Washington, Miami, Pittsburgh, Arizona, Colorado wouldn't take a roll of the dice. All it costs is a roster spot, and if he sucks, you cut him.
Good news for the Sox though, even if he's still unlikely to make it to the bigs in 22. I assume he'll be milb FA at the end of this season if not added back to 40 man?
