Are the Twins seriously considering keeping Brian Dozier on the roster? If you are reading the local beat writers you would think so. But most of this seems to be their own speculation. Terry Ryan says they would consider having a guy bypass AAA. But Terry Ryan has always said that when asked about some young prospect in camp. Usually the comment is combined, as it was here, with some statement about the prospect needing to play every day.
Last year the story of the spring was Luke Hughes. As expected, despite the beat writers stories, Hughes was sent to the minors to start the season. He was called up when Nishioka got hurt.
Dozier is very likely the same story. The Twins seem to think Dozier can play shortstop in the big leagues, which makes him a better prospect than Hughes. But they just signed Jamey Carroll to provide themselves with veteran stability. It seems unlikely that they are going to jump in an entirely different direction based on a good spring training.
The apparent motivation for making that move, according to the bloggers and beat writers, would be to strengthen the utility infielder position. This idea gained credence when they sent Nishioka to AAA. But it is hard to imagine the Twins weakening themselves at shortstop in order to patch a weakness at the end of the bench.
Of course, its possible they will become convinced Dozier is better than either Carroll or Casilla and give him a major league job. But that has nothing to do with Nishioka or any need for a utility infielder. If Dozier wins a spot on the roster, its because the team is convinced he is already the best shortstop in camp. I think that is an longshot, at best.
