|About the stats|
Over the course of his career, Tony Perez made 10,861 plate appearances. Perez was worth 54.0 Wins Above Replacement and 17.9 Wins Above Average.
After adjusting for length of schedule, catchers, and relief pitchers, the 54.0 WAR becomes 54.2 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 17.9 WAA becomes 26.5 adjWAA.
Then, the adjWAR and adjWAA are combined, but with extra weighting given to adjWAA. This gives Perez 101.9 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 95, making him close to the Hall of Stats borderline—but still on the outside.
