Well, to be fair, that's the way most teams operate, if they have a guy who is a dependable closer - the ones that "close by committee" tend to do so because they don't have any one guy who they can count on. With that said, having two guys who are capable might affect your evaluation of whether Perkins or Jepsen is "available" on a particular day. What you need to take full advantage of having two guys capable of closing is at least two guys capable of pitching the eighth inning. Here's the thing, though - - having two guys capable of closing, do you now become reluctant to pitch both of them in the same game, similar to the "pinch hitting with your second catcher" thing Gardy was loathe to do? Think about it - if the goal is to spread out the work, then the preferred practice would be to avoid pitching them both in the same game because doing so means it's been "the same number of days since they pitched" for both of them until you spread them out again. Sure, you can ignore that for a couple of days in important games, but at some point in time, that thought starts lighting up like a neon sign . . . . Maybe you let matchups determine it - if both are available, who's coming up in the 9th for the other side & which guy has a better record against those guys?
