I'm not sure it's all that big of a deal, unless it saves us $10+M on the luxury tax limit.
I mean, whose 40 man roster spot is he protecting? Brentz? Coyle? Noe Ramirez?
It's got to be an attempt to save on the luxury tax, otherwise, what would be the harm in giving him a little more time? How much time has Brentz had to win a slot on the 25 man roster?
I'm not complaining about the move, but if we end up paying him to play elsewhere, I'd rather had had us keep him in the system a while longer.
I'm not privy to what Sox management knows about Castillo; maybe they are 99.9% positive this kid is a flop, and even Brentz has a better chance than him...
