|About the stats|
Over the course of his career, Sam Mertes made 5,015 plate appearances and pitched 4 innings. Mertes was worth 23.4 Wins Above Replacement (23.2 as a hitter and 0.2 as a pitcher) and 6.3 Wins Above Average (6.1 as a hitter and 0.2 as a pitcher).
After adjusting for length of schedule, catchers, and relief pitchers, the 23.4 WAR becomes 24.6 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 6.3 WAA becomes 8.8 adjWAA.
Then, the adjWAR and adjWAA are combined, but with extra weighting given to adjWAA. This gives Mertes 40.4 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).
Sam Mertes has a Hall Rating of 38, leaving him nowhere close to induction to the Hall of Stats.
