|About the stats|
Over the course of his career, Jordy Mercer made 3,416 plate appearances. Mercer was worth 6.8 Wins Above Replacement and -4.0 Wins Above Average.
After adjusting for length of schedule, catchers, and relief pitchers, the 6.8 WAR becomes 6.7 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 -4.0 WAA becomes 0.7 adjWAA.
Then, the adjWAR and adjWAA are combined, but with extra weighting given to adjWAA. This gives Mercer 8.0 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).
Jordy Mercer has a Hall Rating of 7, leaving him nowhere close to induction to the Hall of Stats when eligible.
