There's plenty of reporting that the Twins don't think Kepler can handle ML pitching, despite what he's hitting at AA. Arcia and (soon) Hicks are better options for reasonable depth. Berrios just pitched today; it's not clear that the Twins won't call him up. Even if they elect to not bring him up, there is some organizational strikes against a call up: youth/professional inexperience, hence an inning threshold; he's not on the forty man roster; and there's no clear-cut pitcher to replace (Pelfrey and Milone are mediocre, but that they need replacement is not clear-cut) (I like this reason least, because all the pitchers are mediocre, and Berrios is bound to be better than one of them--which one?). All that said, if Berrios is showing no signs of fatigue, and penchant for ML dominance, bring the dude up.
