We already know he was Plan B. I think the plan all along when they decided against Graterol was to get another pitcher (where LA balked?) or get the best prospect they can to flip for one.
Downs might be a stud. But so far, he has only played A ball. I just cannot get too excited about players in A ball to the point where I say they will be better than actual Major Leaguers. After all, there is a better chance he never gets past Pawtucket, statistically speaking.
The Sox 2B depth chart in the minors might suck, but how exactly does their pitching look in the majors?
