|About the stats|
Over the course of his career, Bruce Ruffin pitched 1,268 innings and made 341 plate appearances. Ruffin was worth 8.2 Wins Above Replacement (9.8 as a pitcher and -1.5 as a hitter) and -2.7 Wins Above Average (-1.3 as a pitcher and -1.5 as a hitter).
After adjusting for length of schedule, catchers, and relief pitchers, the 8.2 WAR becomes 10.1 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 -2.7 WAA becomes 7.6 adjWAA.
Then, the adjWAR and adjWAA are combined, but with extra weighting given to adjWAA. This gives Ruffin 23.8 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).
Bruce Ruffin has a Hall Rating of 22, leaving him nowhere close to induction to the Hall of Stats.
