Over the course of his career,
Mark McGwire
made 7,660 plate appearances.
McGwire was worth 58.7 Wins Above Replacement
and 37.2 Wins Above Average.
After adjusting for length of schedule, catchers, and relief pitchers, the 58.7 WAR becomes
59.3 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 37.2 WAA becomes 38.8 adjWAA.
Then, the adjWAR and adjWAA are combined, but with extra weighting given to adjWAA.
This gives McGwire 124.9 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).
Mark McGwire has a Hall Rating of 123,
making him a member of the Hall of Stats.
