I suppose it depends on your team makeup. In Petco Park I had a starting rotation of Lincecum, Sabbathia, Becket and Hamels.
My second team is also in Petco with a rotation of Vazquez, Sabbathia, Becket and Hamels. After 48 games I've managed 10 shutouts and only 5 saves. Adams has only managed 10 innings, which is again nearly half of my releif innings.
