|About the stats|
Over the course of his career, Dave Righetti pitched 1,403 innings and made 16 plate appearances. Righetti was worth 21.3 Wins Above Replacement (21.3 as a pitcher and 0.0 as a hitter) and 7.0 Wins Above Average (6.9 as a pitcher and 0.0 as a hitter).
After adjusting for length of schedule, catchers, and relief pitchers, the 21.3 WAR becomes 24.8 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 7.0 WAA becomes 12.6 adjWAA.
Then, the adjWAR and adjWAA are combined, but with extra weighting given to adjWAA. This gives Righetti 47.5 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).
Dave Righetti has a Hall Rating of 45, leaving him nowhere close to induction to the Hall of Stats.
