What's WERCing for the Tigers?

To follow-up on my previous post on wOBA, Base Runs and WERC, I have done the calculations for Tigers pitchers.  The statistics in the Table 1 below are:

•  Weighted On-Base Average (wOBAA)

•  Base Runs Above Average (RAA) or number of runs saved compared to an average pitcher.

• Weighted Component ERA (WERC) tells us what a pitcher's ERA should be based on base runners, total bases and home runs allowed.  

The WERC statistic falls between ERA and FIP in terms of how much noise we remove in measuring a pitcher's performance.  It holds a pitcher responsible for hits allowed, but not for timing of events.  There are no big surprises on the table.  The top six - Doug Fister, Duane Below, Justin Verlander, Octavio Dotel, Drew Smyly and Phil Coke - have done well, while the others have struggled.  It's still very early though and these numbers should change a lot by the end of the month.  I intend to update these numbers periodically throughout the season.
