It depends on personal perspective, I think. The Twins are obviously high on Rosario, as they were Polanco and Santana last season. There's something about those kids the Twins really like. In the case of Santana, it was obviously warranted and worked out wonderfully. Inversely, the Twins are extremely skeptical of Hicks, and for good reason. My personal feeling about that is "Well, no ****, Sherlock. Why didn't you recognize that in 2013?" but I'm happy they finally got on board with what seemed like a no-brainer decision to me. Do the Twins let work ethic and attitude influence their decisions, particularly with prospects? Yeah, I think they factor it in quite a bit and that's probably the right decision. Coming to the big leagues and playing every day is about a lot more than talent. All one has to do is look at Delmon Young to see that in action. Do the Twins let attitude and work ethic influence their decision-making too much? Well, that depends on your view of the situation... But I don't think Rosario's call-up is much of an indication of anything. The Twins all but said "we need an outfielder for a brief stint; he's here for two weeks and then goes back to the minors". Some disagree with me but I think the Twins' call-up of Rosario has equal parts "we don't want to mess with Aaron while he's rolling" and "we like Eddie quite a bit".
