I can't help but like this trade as a Mets fan. Butera and Martin were just classic Minor League Fodder, maybe if the Twins are lucky they can get a couple Bench Players out of them. Whereas Castillo is still a productive player, even if he isn't quite what he once was. I just hope the Mets don't bury Gotay on the bench as he was hitting well lately.
We'll turn these cats into reliable starters, then by the time they're 28ish, we'll deal them for more no-name prospects and do the same thing. We are amazing like that.
