David Stearns learning the hard way this week that he's not running a fantasy baseball team. You don't get to move pieces around the board without regard to what it's doing to actual human beings without repercussions.
I used to think Stearns was a great GM/Pres Baseball Ops. I don't think that anymore.
Edit - My comment was more about the Hader trade/Dinelson DFA, et al., than this issue with Barker, which appears to not be an issue at all.
