Diamond is probably due for a statistical regression, but count me among those who don't see any reason to think he'll blow up. I think eating 200 innings at a 4.00 clip is a nice expectation, and if he falls a bit short (say, 175 innings and 4.50), that's still a useful thing to have in most rotations in the majors, and especially the Twins'. Diamond has nice mechanics that seem to make him less of a candidate for injury, and if he can keep hitters off balance by disguising his pitches well, there's no reason to think he can't be an effective control pitcher. No, I don't think he repeats his out-of-his-mind first half performance of last year, but I think he'll be quite effective, actually.
