|About the stats|
Over the course of his career, Fergie Jenkins pitched 4,500 innings and made 1,010 plate appearances. Jenkins was worth 84.4 Wins Above Replacement (82.2 as a pitcher and 2.0 as a hitter) and 43.9 Wins Above Average (41.9 as a pitcher and 2.0 as a hitter).
After adjusting for length of schedule, catchers, and relief pitchers, the 84.4 WAR becomes 85.1 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 43.9 WAA becomes 44.5 adjWAA.
Then, the adjWAR and adjWAA are combined, but with extra weighting given to adjWAA. This gives Jenkins 165.2 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).
Fergie Jenkins has a Hall Rating of 155, making him a member of the Hall of Stats.
