I don't think AA will call up guys that are performing well in Buffalo unless he can send them back there without losing them. Guys like Negrych, Jimenez, Gomez and others were signed to help keep the promise (yes another promise), AA made to the Bisons' owner. This, at least in part, explains why a guy like Negrych, who's a Buffalo native, hasn't been given a chance with the Blue Jays. I don't think Wagner would be called up unless he has options, which I doubt he does.
