If he had not had the year he had last year, there would be cries to dump him.  4 losses and 4 blown saves in 60 games.  This team will not win anything with that kind of performance from their closer.  If I had my way, I would give Melancon the closers role, start stretching out Aceves, a la Morales.  And trade Aceves to the first team that offers up two bonafide prospects.  Said prospects would be part of my package for a starter, along with Iggy and Youk (and maybe Doubront, if I could get a Gio Gonzalez level guy).
