|About the stats|
Over the course of his career, Hoyt Wilhelm pitched 2,254 innings and made 493 plate appearances. Wilhelm was worth 47.3 Wins Above Replacement (50.1 as a pitcher and -2.8 as a hitter) and 24.1 Wins Above Average (26.9 as a pitcher and -2.8 as a hitter).
After adjusting for length of schedule, catchers, and relief pitchers, the 47.3 WAR becomes 55.7 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 24.1 WAA becomes 33.4 adjWAA.
Then, the adjWAR and adjWAA are combined, but with extra weighting given to adjWAA. This gives Wilhelm 115.1 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).
Hoyt Wilhelm has a Hall Rating of 108, making him a member of the Hall of Stats—but one who sits very close to the borderline.
