I'd like to take a tangent from what we are discussing here (to be honest, I started thinking about it from D-rock's post). Should we expect major-league relievers to be able to pitch more than one inning per outing? Obviously no one has the foresight to know whether they will need their closer for the next day's game, so the guy ideally should be ready for every game. Can any closers or setup men regularly pitch more than one inning, and still be ready for the next game? I would guess that this is something that varies from pitcher to pitcher. Also, you have to take into account every time the set up man or closer has to warm up in the bullpen. Often, they throw more pitches in there than actually in the game. Bottom line for me is: You have to limit your closer or setup man to however much pitching he can do while still being fresh and ready to work in the next game. If that means limiting each to only one inning, then I think that is what you have to do. Perhaps if there is a day off the next day, then you can have the setup man or closer work extra. Otherwise, I think it is the job of the manager to know the stamina and fatigue factors of his setup man and closer to ensure that each man (especially the closer) is available for every game possible. It seems to be taken for granted that setup men and closers can only pitch one inning if they are to be used in consecutive games. Maybe that is not the case. Maybe just no one wants to be the one to try it.
