The Nats have been conducting a GM search, which doesn't seem to bode well for Rizzo. But the club-owning Lerners are nothing if not unpredictable. The field has apparently been narrowed to Rizzo plus two well-respected assistant GMs, Boston's Jed Hoyer and Arizona's Jerry DiPoto. The White Sox's highly regarded Rick Hahn, a Chicago native content to be assist Williams, bowed out of the derby. There is some thought a permanent GM could be named by the end of the month.
