I've come to really trust your insight, and you do a great job with your site. It has become a daily read of mine.
Now that I have gotten the "butt" kissing out of the way
, I have to respectfully disagree with your evaluation of Herrera. I have been taught to believe that their is no correct way that a pitcher must get outs. Guys like Chad Bradford, Chris Hammond, and Jon Coutlangus among others have demonstrated this (Moneyball rationale). Clearly, he can strike out guys in AA, and I see no reason why he can't continue to strike out a good rate in the majors. Plus, he's only 23. Sure, he may not be great, but why can't he be at least an effective LOOGY? It seems that even if he only stirkes out around 7 per 9 IP in MLB, he gets enough ground balls to pitch to contact. Also, if he is only coming in to face a couple of batters per appearance, why can't his different style be effective, at least for a couple of years?
You know more than me, so please tell me why I'm wrong
