If they want to keep 13 pitchers (there ought to be some kind of law against that!) then they keep Robertson and Burnett, put Wood on the DL, and Walters stays off the major league roster - easy-peasy, no 40-man roster moves needed. But if they want to keep Wilkin, they have to move someone off the 40-man. Hernandez makes the most sense to me; as a soft-tossing AAAA type, he would seem to be the least likely to be claimed. He'd get outrighted to AAA after he clears waivers and stay in the organization. Also, don't the call-ups from last November have to stay on the 40-man for a certain amount of time? Herrmann, Theilbar, Hermsen, Pinto, etc. all fall into that category. But even so, I'd expose Hernandez to waivers and try to outright him to AAA. Sure, he had a good spring, but then again Walters looked good in the bullpen before his start yesterday, too.
