We'll see, but I just don't see Elias concerned over control six years from now with a 25-year old. Plus, we don't know what the next bargaining agreement will hold for free agency or arbitration eligibility.
I understand your perspective, but I don't think I'd handle it that way if I were Elias in the context of this team (not a contender). Zimmermann could get a shot and so could the rule V guys. I would only promote Baumann for that role if the other guys clearly don't belong.
I know he'll be 31, but I'd still value that year with a high-upside arm.
