Nothing's wrong with Haren. He's a young pitcher without too much experience and is still working on a few things that are giving him trouble, mainly how to adjust during an inning. If you look at the inning-to-inning boxscore for Haren you'll see all the trouble generally comes in one or two innings. Against the Tigers, for example, it came in the 4th and 5th innings. He had pitched well against the Tigers the previous ten or so innings he had pitched against them, but once he was in a bad inning, he couldn't adjust. That comes from experience, not stuff. Once he figures out how to adjust during an innings rather than only between games, he'll be a very nice pitcher consistantly.
