|About the stats|
So far in his career, Sonny Gray has pitched 1,387 innings and made 118 plate appearances. Gray has been worth 24.8 Wins Above Replacement (25.1 as a pitcher and -0.2 as a hitter) and 12.6 Wins Above Average (12.8 as a pitcher and -0.2 as a hitter).
After adjusting for length of schedule, catchers, and relief pitchers, the 24.8 WAR becomes 26.2 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 12.6 WAA becomes 15.1 adjWAA.
Then, the adjWAR and adjWAA are combined, but with extra weighting given to adjWAA. This gives Gray 53.4 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).
Sonny Gray has a Hall Rating of 50, meaning he would not be in the Hall of Stats if his career ended today.
