For the Twins to compete, better be Harden
I find it hard to embrace the hope that he can be what he once was. But I don't know any of the fundamentals about what it takes for a pitcher to come back from his injuries.
I attended his first home start when he was with the A's in 2003 and his changeup was absolutely killer - the Indians stood there unable to pull the trigger, time after time after time.
But if he's lost something off the fastball, permanently, can he replicate the old magic? Could be that batters now can say that if it looks like a fastball, treat it like a change up and try to pull it, and if it happens to be a fastball then you may end up going the other way for a base hit instead. As I said, I need someone with better grasp of hitting than I have, to tell me. And if he tries to win with something else than a changeup, then he's not the same pitcher and the previous track record wouldn't count for a lot.
