Yes and no. Berrios is not some guy who wandered in off the street. He's a high draft pick. The whole point is for him to pitch in MLB, and he's demonstrated he's ready to do that. And just as important, the Twins need him. In my opinion, calling him up is best for both parties. (Although I note you are one of the posters who think the Twins should have thrown in the towel on 2015 ) Do the Twins know what's best for Berrios? Probably, but not necessarily. The Twins operate as a traditional organization with time-tested methods for player development, methods which a lot of progressive organizations seem to have abandoned. Given Berrios made it his stated mission to pitch in MLB by his 21st birthday (May 27th), and given how well he's pitched since then and handled himself, I'd wonder if the right thing would have been to call him up last month. They may yet call him up, so we'll see. In other organizations, you see top prospects making very short starts in Milb in order to conserve energy, and you see 21 year old pitchers contributing in pennant chases, as bullpen or starters. Lance McCullers is a real good example at the moment. Age 21 is not as young as it sounds anymore. So, the disappointment being expressed here is not exactly coming from out of no where.
