Mess, sanchez is still in A ball where hes been for a few years. Still needs to do double and triple A and who knows for how long. Optimistically, won't see him before at least 2016 unless theres a major change in Yankee minor league philosophy.
Yes, I would say he needs two more years in the minors. That's also the case which most of their other prospects as well.
My feelings are a little different on this topic. Especially this year where its obvious that we're not going anywhere. So I'm hoping that come 9-1 they not only bring up the kids but also give em a chance to play. Hell even bring up 2-3 of them now. You need room? no problem release Hafner make room.
