Key thing to remember about MRs is when you only pitch 70 IP or so per season, you're subject to a lot more variance than SP. Sabathia's ERA was just a touch under 5 when he reached 70 IP last year - if he was a reliever, that's his season right there.
You can get a pretty good idea of which MR are actually the best pitchers by looking at K, BB and HR rates. I try to find guys who are consistently good in those categories over the span of a couple years. Manny Delcarmen is an example that's working well for me this season.
