Over the course of his career,
Tony Perez
made 10,861 plate appearances.
Perez was worth 50.1 Wins Above Replacement
and 18.1 Wins Above Average.
After adjusting for length of schedule, catchers, and relief pitchers, the 50.1 WAR becomes
50.3 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 18.1 WAA becomes 26.6 adjWAA.
Then, the adjWAR and adjWAA are combined, but with extra weighting given to adjWAA.
This gives Perez 95.3 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).
Tony Perez has a Hall Rating of 94,
making him close to the Hall of Stats borderline—but still on the outside.
