Over the course of his career,
Don Mattingly
made 7,722 plate appearances.
Mattingly was worth 39.8 Wins Above Replacement
and 17.7 Wins Above Average.
After adjusting for length of schedule, catchers, and relief pitchers, the 39.8 WAR becomes
40.2 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 17.7 WAA becomes 22.5 adjWAA.
Then, the adjWAR and adjWAA are combined, but with extra weighting given to adjWAA.
This gives Mattingly 78.3 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).
Don Mattingly has a Hall Rating of 77,
leaving him short of induction to the Hall of Stats.
