Hall of Stats

Over the course of his career, Firpo Marberry pitched 2,067 innings and made 731 plate appearances. Marberry was worth 30.8 Wins Above Replacement (31.7 as a pitcher and -1.1 as a hitter) and 9.6 Wins Above Average (10.7 as a pitcher and -1.1 as a hitter).

After adjusting for length of schedule, catchers, and relief pitchers, the 30.8 WAR becomes 34.1 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 9.6 WAA becomes 14.2 adjWAA.

Then, the adjWAR and adjWAA are combined, but with extra weighting given to adjWAA. This gives Marberry 59.7 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).

Firpo Marberry has a Hall Rating of 56, leaving him nowhere close to induction to the Hall of Stats.
