As I did with my pitcher rankings, I grouped the closers into tiers. There are only three with a fourth category of "other" which bleeds into my middle reliever rankings. This category captures the Cleveland nd Florida situation. I had to double-check Keith Foulke's WHIP and IP they were much better than I had realized and helps explain why the Injun's gave him $5MM for 2007.
