|About the stats|
Over the course of his career, Bump Hadley pitched 2,945 innings and made 1,147 plate appearances. Hadley was worth 35.0 Wins Above Replacement (35.3 as a pitcher and -0.2 as a hitter) and 6.5 Wins Above Average (6.8 as a pitcher and -0.2 as a hitter).
After adjusting for length of schedule, catchers, and relief pitchers, the 35.0 WAR becomes 36.6 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 6.5 WAA becomes 18.1 adjWAA.
Then, the adjWAR and adjWAA are combined, but with extra weighting given to adjWAA. This gives Hadley 69.2 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).
Bump Hadley has a Hall Rating of 65, leaving him short of induction to the Hall of Stats.
