|About the stats|
Over the course of his career, Chappie McFarland pitched 841 innings and made 325 plate appearances. McFarland was worth 0.2 Wins Above Replacement (1.1 as a pitcher and -0.8 as a hitter) and -6.6 Wins Above Average (-5.7 as a pitcher and -0.8 as a hitter).
After adjusting for length of schedule, catchers, and relief pitchers, the 0.2 WAR becomes 0.2 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 -6.6 WAA becomes 0.0 adjWAA.
Then, the adjWAR and adjWAA are combined, but with extra weighting given to adjWAA. This gives McFarland 0.2 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).
Chappie McFarland has a Hall Rating of 0, leaving him nowhere close to induction to the Hall of Stats.
