|About the stats|
Over the course of his career, Tony Gwynn made 10,232 plate appearances. Gwynn was worth 69.3 Wins Above Replacement and 37.0 Wins Above Average.
After adjusting for length of schedule, catchers, and relief pitchers, the 69.3 WAR becomes 70.1 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 37.0 WAA becomes 37.0 adjWAA.
Then, the adjWAR and adjWAA are combined, but with extra weighting given to adjWAA. This gives Gwynn 136.7 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).
Tony Gwynn has a Hall Rating of 128, making him a member of the Hall of Stats.
