|About the stats|
Over the course of his career, George Mullin pitched 3,686 innings and made 1,701 plate appearances. Mullin was worth 47.6 Wins Above Replacement (34.8 as a pitcher and 12.8 as a hitter) and 15.1 Wins Above Average (2.8 as a pitcher and 12.2 as a hitter).
After adjusting for length of schedule, catchers, and relief pitchers, the 47.6 WAR becomes 48.4 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 15.1 WAA becomes 10.0 adjWAA.
Then, the adjWAR and adjWAA are combined, but with extra weighting given to adjWAA. This gives Mullin 66.4 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).
George Mullin has a Hall Rating of 62, leaving him short of induction to the Hall of Stats.
