Wow. I thought the inflated value of saves in Roto would cause a significant skew in these rankings, but the impact is mostly felt at the bottom of the chart. Baseball Prospectus' rankings almost mirror the Patton $ values 1-4, and the differences at the bottom aren't crazy. It is only when you get down to the mediocre closing options like Cordero where closers start to disappear.
Cordero is losing money in ERA/WHIP, and that's definitely not a coincidence. While there isn't a strong corollary between ERA/WHIP and WAR or WARP1, you're not going to produce a lot of relief value in any system with subpar ERA/WHIP. Another way to look at this is that while a strong ERA/WHIP performer might not score well in WAR or WARP1, the opposite almost definitely won't happen.
Since BP has Wagner first, I'll take the easy way out and go Wagner, Wilson and Bell here. Marmol had a great year, but those walks give me pause.
