Over the course of his career,
Keith Hernandez
made 8,553 plate appearances.
Hernandez was worth 57.1 Wins Above Replacement
and 31.9 Wins Above Average.
After adjusting for length of schedule, catchers, and relief pitchers, the 57.1 WAR becomes
58.0 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 31.9 WAA becomes 34.5 adjWAA.
Then, the adjWAR and adjWAA are combined, but with extra weighting given to adjWAA.
This gives Hernandez 116.3 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).
Keith Hernandez has a Hall Rating of 115,
making him a member of the Hall of Stats.
