Welcome to the site, I think what you're referring to is tRA+ which is similar to OPS+ and ERA+. A score of 100 in tRA+ means that the pitcher had a tRA that was exactly league average. A score of 80 means that his tRA was 20% below league average. A score of 120 means that his tRA was 20% above league average. tRA* (with the asterisk) is tRA but regressed back to league averages. Both tRA and tRA* are scaled to runs-per-nine-innings. Mathew Carruth has a piece of rotation slots by tRA+ which you can read here: http://www.statcorner.com/blog/2008/10/rotation-s...

I love the charts and numbers, but am baffled in one respect by this set: the tRA on StatCorner has an asterisk and is expressed in numbers at about 100 +/- 30; but the numbers you use are comparable to the familiar ERA or the RA/9 figures, with an integer followed by a two-place decimal. What is the relation between these? How can one translate, for example, StatCorner's sorting out of starting pitchers into five groups, #1-#5, into an ordered appraisal of the Giants' starters? Thanks.
