Tough call. I think, arm injury aside, Bundy is as close to having elite pitching skill as you can get in a prospect. But the injury is an issue obviously. Castro just provides such an enormous value not just on the field but in the budget as well. I think I'd need more. Throw in Hunter Harvey and I need to think about it a lot harder, but I think Baltimore says no to that deal. The more I think about Castro, what he's doing, and how much he costs, the less I want to deal him. I'd rather deal an unknown commodity in Russell or Baez because a) there's still bust potential while Castro has already proven what he can do and b) I like the idea of Beane's philosophy of teams overvaluing prospects and I think the Cubs could easily exploit that idea. But in that aspect, you could move the prospects for legit MLB pitching instead of other prospects. On a side note, unrelated to Castro and stuff, I kind of want the Cubs to snipe Brian Matusz from the O's and Bosify him.
