|About the stats|
Over the course of his career, Ed Williamson made 5,082 plate appearances and pitched 35 innings. Williamson was worth 35.6 Wins Above Replacement (36.1 as a hitter and -0.4 as a pitcher) and 17.5 Wins Above Average (18.4 as a hitter and -0.7 as a pitcher).
After adjusting for length of schedule, catchers, and relief pitchers, the 35.6 WAR becomes 47.5 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 17.5 WAA becomes 20.9 adjWAA.
Then, the adjWAR and adjWAA are combined, but with extra weighting given to adjWAA. This gives Williamson 85.1 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).
Ed Williamson has a Hall Rating of 80, leaving him short of induction to the Hall of Stats.
