I read the Yankees would have to be blown away to part with Montero, but they'd deal Banuelos, Austin Romine (their other top catching prospect) and any other necessary pieces in a possible deal. Given that, I don't know if Romine is an improvement over Welington Castillo (other than he's 2 years younger). The Yankees are definitely interested, but I don't think they budge on Montero. They were almost against trading him for Cliff Lee, let alone for Garza.
