Over the course of his career,
Joe Kelley
made 8,139 plate appearances.
Kelley was worth 47.3 Wins Above Replacement
and 22.9 Wins Above Average.
After adjusting for length of schedule, catchers, and relief pitchers, the 47.3 WAR becomes
51.5 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 22.9 WAA becomes 27.7 adjWAA.
Then, the adjWAR and adjWAA are combined, but with extra weighting given to adjWAA.
This gives Kelley 98.3 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).
Joe Kelley has a Hall Rating of 97,
making him close to the Hall of Stats borderline—but still on the outside.
