|About the stats|
Over the course of his career, Pat Mahomes pitched 709 innings and made 46 plate appearances. Mahomes was worth 0.1 Wins Above Replacement (-0.4 as a pitcher and 0.5 as a hitter) and -5.5 Wins Above Average (-6.2 as a pitcher and 0.5 as a hitter).
After adjusting for length of schedule, catchers, and relief pitchers, the 0.1 WAR becomes 0.2 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 -5.5 WAA becomes 1.4 adjWAA.
Then, the adjWAR and adjWAA are combined, but with extra weighting given to adjWAA. This gives Mahomes 2.7 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).
Pat Mahomes has a Hall Rating of 3, leaving him nowhere close to induction to the Hall of Stats.
