|About the stats|
Over the course of his career, Fred Anderson pitched 986 innings and made 339 plate appearances. Anderson was worth 3.7 Wins Above Replacement (5.4 as a pitcher and -1.8 as a hitter) and -2.1 Wins Above Average (-0.3 as a pitcher and -1.8 as a hitter).
After adjusting for length of schedule, catchers, and relief pitchers, the 3.7 WAR becomes 4.2 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 -2.1 WAA becomes 6.2 adjWAA.
Then, the adjWAR and adjWAA are combined, but with extra weighting given to adjWAA. This gives Anderson 15.4 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).
Fred Anderson has a Hall Rating of 14, leaving him nowhere close to induction to the Hall of Stats.
