Over the course of his career,
Jerry Mumphrey
made 5,545 plate appearances.
Mumphrey
was worth
22.6 Wins Above Replacement
and 4.1 Wins Above Average.
After adjusting for length of schedule, catchers, and relief pitchers, the 22.6 WAR becomes
23.3 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 4.1 WAA becomes 9.3 adjWAA.
Then, the adjWAR and adjWAA are combined, but with extra weighting given to adjWAA.
This gives Mumphrey 40.0 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).
Jerry Mumphrey has a Hall Rating of
38,
leaving him nowhere close to induction to the Hall of Stats.
