Detroit wants two relievers, they think they can reach the World Series this year, if they fix the back end of their bullpen; K-Rod sounds like he's their choice as closer. Remember last year when Baltimore wanted Greinke, but their farm system was pretty much Manny Machado, Dylan Bundy, and ? Detroit has a similar situation, their system isn't very deep at the moment, but at the top they have 3B/OF Nick Castellanos, and OF Avisail Garcia. These two aren't in the class of Machado and Bundy, but they're both excellent prospects. Castellanos profiles to be a .300 hitter, with 20 homers/40 doubles. He may be able to handle third base in the majors, if not, he's an outfielder. Garcia is probably the riskier of the two, he's got plenty of talent, but he's rough, a free-swinger at this point. Best case for Garcia - he becomes a 20/20-type outfielder. Both of these guys have a great deal of potential, and scouts think Detroit would deal one of them if they thought they were getting enough to make them favorites to reach the World Series...which in their case, essentially means if they get their bullpen over the top. This will mean K-Rod, and another good bullpen arm, one they control beyond this season, so Axford, or Henderson. I don't know if Detroit would give up one of these guys for two relievers or not, but it's not as crazy as it may sound, they're going for it, and a better bullpen may actually be all they need this year. If the Brewers are going to pull a deal this July that is universally praised, Detroit may be the best bet.
