With the number of top prospects that could be MLB ready next year, it would seem the Twins would not want to start all of their clocks at the same time. Sano, Rosario, Buxton, Meyer, May, Tonkin, etc., are all projected to be very important pieces to the Twins. It would be problematic for the Twins if they were all entering arbitration and free agency at the same time. Therefore, why not call Sano up now?
