Relief Pitcher Repetoire Update

The 1st evaluation (FB) has been completed.

In regards to the 3 True Outcomes (BB/9, K/9, HR/9), the pitchers regressed the following:
> 85 % FB's = 68.75 % Regression
80 - 84.99 % FB's = 63.64 % Regression

And in regards to DICE:
> 85 % FB's = 57.58 % Regression
80-84.99 % FB's = 56.82 % Regression

The qualifiers in 2008 who are using 2009 as their evaluation year:
> 85 % : Grant Balfour
80-84.99: Joe Beimel, Octavio Dotel, Matt Thornton, Jonathan Papelbon

The ideal is to utilize these numbers to assign a formula to the pitcher's repetoire and use this resulting number to evaluate if their repetoire is suitable to them succeeding the next season.

NOTE: These numbers do not include penalties to pitchers for injury issues and that will be addressed after the completion of the evaluation of each individual pitch.
