|About the stats|
Over the course of his career, Joe Mauer made 7,960 plate appearances. Mauer was worth 55.1 Wins Above Replacement and 27.6 Wins Above Average.
After adjusting for length of schedule, catchers, and relief pitchers, the 55.1 WAR becomes 62.1 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 27.6 WAA becomes 33.5 adjWAA.
Then, the adjWAR and adjWAA are combined, but with extra weighting given to adjWAA. This gives Mauer 122.4 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).
Joe Mauer has a Hall Rating of 115, meaning he will be in the Hall of Stats when eligible.
