Hall of Stats

Over the course of his career, Jim Perry pitched 3,285 innings and made 980 plate appearances. Perry was worth 41.6 Wins Above Replacement (38.4 as a pitcher and 3.2 as a hitter) and 13.9 Wins Above Average (10.7 as a pitcher and 3.2 as a hitter).

After adjusting for length of schedule, catchers, and relief pitchers, the 41.6 WAR becomes 43.5 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 13.9 WAA becomes 19.5 adjWAA.

Then, the adjWAR and adjWAA are combined, but with extra weighting given to adjWAA. This gives Perry 78.6 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).

Jim Perry has a Hall Rating of 74, leaving him short of induction to the Hall of Stats.
