Hall of Stats

Over the course of his career, Billy Wagner pitched 903 innings and made 21 plate appearances. Wagner was worth 27.8 Wins Above Replacement (27.8 as a pitcher and 0.0 as a hitter) and 16.3 Wins Above Average (16.5 as a pitcher and 0.0 as a hitter).

After adjusting for length of schedule, catchers, and relief pitchers, the 27.8 WAR becomes 33.2 adjWAR. Then, WAA is adjusted by ignoring negative seasons (thus, truly capturing a player’s peak seasons) and making similar adjustments for catchers and relief pitchers. After these adjustments, the 16.3 WAA becomes 20.1 adjWAA.

Then, the adjWAR and adjWAA are combined, but with extra weighting given to adjWAA. This gives Wagner 69.4 wWAR. wWAR is then converted to Hall Rating. A Hall Rating of 100 represents the Hall of Stats borderline (similar to OPS+ or wRC+, where 100 represents league average).

Billy Wagner has a Hall Rating of 65, leaving him short of induction to the Hall of Stats.
