Introducing Pitcher Efficiency Rating (PER)

I do not claim to be a great sabretician and I understand that this formula might have been created by someone else without me being aware and that is the case then I am sorry. Pitcher Efficiency Rating is a very simple formula and is just innings pitched/total batters faced. As you would expect, the best pitchers lead this category so there are very few players that jump out of nowhere but I think it helps sort out who is the best among the best. If you would combine both relievers and starters for this statistic you would find that the 10 rated pitchers are relievers while the first starter to appear in this rating would be Jered Weaver at #11. Here we take a look at the top 15 starting pitchers in baseball:

Player	Team	Efficiency Rating
Jered Weaver	Angels	0.255737705
David Price	Rays	0.252392344
R.A. Dickey	Mets	0.251605759
Clayton Kershaw	Dodgers	0.251376147
Matt Cain	Giants	0.249824971
Cliff Lee	Phillies	0.249695493
Justin Verlander	Tigers	0.249058577
Chris Sale	White Sox	0.248704663
Felix Hernandez	Mariners	0.248571429
Cole Hamels	Phillies	0.248096886
Jake Peavy	White Sox	0.246783626
Mike Minor	Braves	0.246016484
Hiroki Kuroda	Yankees	0.245886443
Madison Bumgarner	Giants	0.245111896
Jason Vargas	Mariners	0.24475761

Jered Weaver comes in as #1 in PER

There are no real surprises in that list other Jason Vargas and Mike Minor, neither of whom appear in the top 40 of ERA. This can be accounted to weak defense although I doubt that is the only reason. Johnny Cueto, who is #7 in ERA, falls just outside the top 15. David Price has the best ERA but Jered Weaver beats him out in the Efficiency Rating. This should be no surprise considering Weaver is considered by many as the best pitcher in baseball. Now let’s take a look at the top 10 relievers in baseball.

Player	Team	Rating
Craig Kimbrel	Braves	0.269604
Fernando Rodney	Rays	0.264855
Casey Janssen	Blue Jays	0.260426
Brad Ziegler	Diamondbacks	0.258594
Kenley Jansen	Dodgers	0.258333
Jake McGee	Rays	0.257767
Aroldis Chapman	Reds	0.257143
Kris Medlen	Braves	0.256398
Jason Motte	Cardinals	0.255839
Sergio Romo	Giants	0.255189

Former Dominican Catcher
and current Dodgers closer Kenley
Jansen is one  of the top relief pitchers

Again, there are no surprises here as Craig Kimbrel, probably the best closer in baseball heads the list. The Rays and Braves seem to have the best the best bullpen as they both have two of the top relief pitchers according to efficiency rating. For full ratings you can check out these links.
