Don't sleep on Robert Stephenson being ready at any given point. I am convinced that there was a long stretch of time last year when he would have been very successful in the Major Leagues with the games he was throwing despite being in Dayton. While he will begin the year in AA (likely), and he isn't on the 40-man roster, I don't think they will hesitate to call him up if he is actually ready and a spot opens up.
