|About the stats|
Over the course of his career, Bill Anderson pitched 8 innings and made 3 plate appearances. Anderson was worth -0.2 Wins Above Replacement (-0.2 as a pitcher and 0.0 as a hitter) and -0.2 Wins Above Average (-0.2 as a pitcher and 0.0 as a hitter).
After adjusting for length of schedule, catchers, and relief pitchers, the -0.2 WAR becomes -0.1 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 -0.2 WAA becomes 0.0 adjWAA.
Then, the adjWAR and adjWAA are combined, but with extra weighting given to adjWAA. This gives Anderson -0.1 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).
Bill Anderson has a Hall Rating of 0, leaving him nowhere close to induction to the Hall of Stats.
