Using PER to rank the major league bullpens

despite the #1 bullpen, the rays were unable to
make the playoffs

It is commonly known that a good bullpen is a key to a strong season. Now that the season only has one day left I believe that now is a fair time to assess each team's bullpen for the 2012 season. According to PER , Hawks Report's new metric, PER, 7 out of the top 10 best bullpens in baseball have reached the playoffs. The number one bullpen in baseball , the Rays,are out of the Wild Card Showdown by 3.5 games before the last games end . The Diamondbacks also find themselves in the top 10 at spot number 6, they werable to finish 6 games out of the wild card despite also having one of the better offenses in the game. The three playoff teams that were outside the top 10 were the Cardinals (16), Tigers (19), and the Giants (25). Here are your 2012 team bullpen PER rankings. Teams in yellow have clinched the wild card,, blue have clinched the division, and orange have clinched a playoff spot.
