|About the stats|
Over the course of his career, John Mayberry made 6,447 plate appearances. Mayberry was worth 25.1 Wins Above Replacement and 2.7 Wins Above Average.
After adjusting for length of schedule, catchers, and relief pitchers, the 25.1 WAR becomes 25.5 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 10.6 adjWAA.
Then, the adjWAR and adjWAA are combined, but with extra weighting given to adjWAA. This gives Mayberry 44.6 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).
John Mayberry has a Hall Rating of 42, leaving him nowhere close to induction to the Hall of Stats.
