Hall of Stats

Over the course of his career, Ben Chapman made 7,427 plate appearances and pitched 141 innings. Chapman was worth 42.7 Wins Above Replacement (42.2 as a hitter and 0.6 as a pitcher) and 15.9 Wins Above Average (16.5 as a hitter and -0.6 as a pitcher).

After adjusting for length of schedule, catchers, and relief pitchers, the 42.7 WAR becomes 43.7 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 15.9 WAA becomes 18.3 adjWAA.

Then, the adjWAR and adjWAA are combined, but with extra weighting given to adjWAA. This gives Chapman 76.6 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).

Ben Chapman has a Hall Rating of 72, leaving him short of induction to the Hall of Stats.
