|About the stats|
So far in his career, Jacob deGrom has pitched 1,326 innings and made 423 plate appearances. deGrom has been worth 43.8 Wins Above Replacement (41.1 as a pitcher and 2.7 as a hitter) and 32.9 Wins Above Average (30.3 as a pitcher and 2.6 as a hitter).
After adjusting for length of schedule, catchers, and relief pitchers, the 43.8 WAR becomes 48.3 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 32.9 WAA becomes 30.2 adjWAA.
Then, the adjWAR and adjWAA are combined, but with extra weighting given to adjWAA. This gives deGrom 102.7 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).
Jacob deGrom has a Hall Rating of 96, meaning he would not be in the Hall of Stats if his career ended today—but he would be close.
