Hall of Stats

Over the course of his career, Jose Mesa pitched 1,548 innings and made 4 plate appearances. Mesa was worth 11.3 Wins Above Replacement (11.4 as a pitcher and 0.0 as a hitter) and -3.1 Wins Above Average (-3.2 as a pitcher and 0.0 as a hitter).

After adjusting for length of schedule, catchers, and relief pitchers, the 11.3 WAR becomes 14.5 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 -3.1 WAA becomes 8.9 adjWAA.

Then, the adjWAR and adjWAA are combined, but with extra weighting given to adjWAA. This gives Mesa 30.5 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).

Jose Mesa has a Hall Rating of 29, leaving him nowhere close to induction to the Hall of Stats.
