Salazar has had a setback in his recovery, but it seems like he should be available around the All-Star break. More than likely he will be out of the bullpen at first when/if he makes his return this season. I don't expect him to start anytime this season to be honest. If he does spot start it won't be until Sept time frame when they expand the roster and try to get guys some rest.
Right now it looks like it will be the young guys opening up cap with Joyce and Barnes trying to take a spot away from them. I expect a move in the season when/if none of these are are producing. Essentially a move like we did for Crisp/Jay Bruce will happen during the season to help these guys out if production isnt there.
