|About the stats|
Over the course of his career, Percy Forrest pitched 173 innings and made 85 plate appearances. Forrest was worth -4.1 Wins Above Replacement (-4.2 as a pitcher and 0.2 as a hitter) and -5.5 Wins Above Average (-5.4 as a pitcher and 0.1 as a hitter).
After adjusting for length of schedule, catchers, and relief pitchers, the -4.1 WAR becomes -4.0 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 -5.5 WAA becomes 0.0 adjWAA.
Then, the adjWAR and adjWAA are combined, but with extra weighting given to adjWAA. This gives Forrest -4.0 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).
Percy Forrest has a Hall Rating of -4, leaving him nowhere close to induction to the Hall of Stats.
