I have no interest in worrying about service time issues, for either team control or arbitration. For me, I choose the conservative route because I think a player needs to show he can compete/succeed at Triple-A before he gets a shot at the majors. The quality of play there is an improvement over Double-A, and if a player can not do well there he has no business being considered for a major league roster. It doesn't have to be a long look - 2-3 months is fine, and if he shows he can handle it, then give him the big test. I know some see the Triple-A level as a parking spot for borderline major league players and see Double-A as the final "proving ground" for major league talent, but if Sano can not succeed facing pitchers who are borderline major league players, he certainly won't succeed against those who truly belong in the major leagues. Let's make sure he's ready before throwing him in the deep end.
