|About the stats|
Over the course of his career, Bob Harmon pitched 2,054 innings and made 775 plate appearances. Harmon was worth 12.8 Wins Above Replacement (12.3 as a pitcher and 0.4 as a hitter) and -2.8 Wins Above Average (-3.2 as a pitcher and 0.3 as a hitter).
After adjusting for length of schedule, catchers, and relief pitchers, the 12.8 WAR becomes 13.6 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 -2.8 WAA becomes 3.1 adjWAA.
Then, the adjWAR and adjWAA are combined, but with extra weighting given to adjWAA. This gives Harmon 19.2 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).
Bob Harmon has a Hall Rating of 18, leaving him nowhere close to induction to the Hall of Stats.
