If you read the different articles on this move, the picture becomes a little more clear. I'm leaving out the Gleeman article. To me, it seems like he has a axe to grind: i.e. the Twins didn't pick the guy he wanted, Aaron Hicks. From the Strib: “Aaron’s doing fine, I’m hearing some really good things about him,” Molitor said. “It’s important for him to know that he needs to continue to do that over a little bit longer period of time. His day could come soon as well.” From the Wetmore article: Rosario got a boost for his versatility, Ryan said. Despite his struggles in the minor leagues, the Twins want to see how Rosario will perform against the best competition in the world. The Twins did something similar last season with Danny Santana, whose minor league numbers didn't suggest he was prepared to thrive, but who nonetheless took the league by storm with a great rookie season. "This will be an opportunity for him to get his feet wet up here and see what it's all about and see how he responds and see what we've got," Ryan said. "We talked a lot about Eddie in his development and his ability to stay focused day in and day out," Molitor said. "From all the reports he's been doing that very well. He's going to get a chance to play here in the short-term. Excited for him to get this opportunity." This all spells out the simple facts: Hicks, while hitting better now, its still about the "mental mistakes" and "needs to be engaged" issue from Spring Training, per Molitor. And not to put words into their mouths, but I believe Molitor and Ryan are saying this: Rosario seems plays up to the level of competition he faces. Hicks does not.
