|About the stats|
Over the course of his career, Willie Gray made 617 plate appearances and pitched 38 innings. Gray was worth 1.0 Wins Above Replacement (1.4 as a hitter and -0.5 as a pitcher) and -1.3 Wins Above Average (-0.4 as a hitter and -0.9 as a pitcher).
After adjusting for length of schedule, catchers, and relief pitchers, the 1.0 WAR becomes 3.7 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 -1.3 WAA becomes 0.6 adjWAA.
Then, the adjWAR and adjWAA are combined, but with extra weighting given to adjWAA. This gives Gray 4.8 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).
Willie Gray has a Hall Rating of 4, leaving him nowhere close to induction to the Hall of Stats.
