Garza isn't going to the Red Sox. If the Cubs get serious about trading him, Hendry will use the Red Sox as leverage to get a better package from the Yankees. The Yankees have Montero, Banuelos, and Betances....much better prospects than what the Red Sox have left after dealing for Agon. Two of those three, plus about 3 more B prospects would probably do it. At the end of the day, I don't think the Cubs move Garza unless someone like the Yankees make an overwhelming offer Hendry can't refuse. I doubt the Yankees do that, and the Red Sox don't have enough to get it done.
