I think there are two interesting aspects to this situation (Ryan's answer not being one of them): First, Gardy apparently had more pull with personnel decisions than appeared on the surface. And when you got on the wrong side of Gardy, you tended to stay that way. Maybe he basically told the front office to get him out of here because he didn't like the attitude or whatever. Second, I don't think the Twins necessarily should get blamed because of the turnaround as that happens, pretty frequently, actually. The part that was a massive mistake was not keeping him around just in case. He wasn't taking up a 40 man spot and it would have cost them nothing to take a longer look. I actually think the real reason for all of this has nothing to do with the Twins coaching or the Pirates coaching. Rather, he had the "elbow cleanout" procedure and likely wasn't the same pitcher. When he got by that, the old movement, etc. came back. The big mystery technical change he quoted was that he was "flying open". Well, that's as basic as "keep your left arm straight" in golf.
