|About the stats|
Over the course of his career, Jeff Fassero pitched 2,033 innings and made 340 plate appearances. Fassero was worth 23.9 Wins Above Replacement (25.2 as a pitcher and -1.4 as a hitter) and 6.4 Wins Above Average (8.0 as a pitcher and -1.4 as a hitter).
After adjusting for length of schedule, catchers, and relief pitchers, the 23.9 WAR becomes 26.0 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 6.4 WAA becomes 15.2 adjWAA.
Then, the adjWAR and adjWAA are combined, but with extra weighting given to adjWAA. This gives Fassero 53.4 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).
Jeff Fassero has a Hall Rating of 50, leaving him nowhere close to induction to the Hall of Stats.
