I would expect the Red Sox main target is a late inning reliever. It only makes sense. Cherington thought the back end of the bullpen was an area of need so he added Hanrahan and Uehara. Hanrahan is a goner. Bailey looked like he would pick up for Hanrahan, then he bombed out. Uehara has been excellent but has durability questions. Tazawa has been solid but not quite as good as hoped based on last year. Miller and Breslow have both been solid. But for the stretch run another proven late inning reliever would be a big help.
