Mets Relievers in May Part II

Earlier in the month I wrote an article discussing a new statistic I was studying over the course of the month called Reliever Rating. So far in May the ratings of all the Met relievers are...

Mejia -0.907111111 Nieve -1.9314 Feliciano -3.140846154 Rodriguez -1.37763 Takahashi 0.549166667 Valdes -0.11975 Acosta 0.1188 Perez 0.1341 Dessens -1.387 Igarashi -22.63

Some games this month revealed the first real problems with this statistic.  For example, on May 20th against the Nationals.  Pedro Feliciano, entered with the bases loaded and 2 outs in the 8th and gave up 2 runs.  Now this does not sound so bad, however because the Mets were up by 7 when he entered the game.  His small negative score was multiplied by 7, ballooning it to -17.25. 

As you can see the best Met reliever this month has been Hisanori Takahashi and it has not been that close.  However, now with him in the starting rotation who will step up as the relief ace?
