|About the stats|
So far in his career, Madison Bumgarner has pitched 2,192 innings and made 731 plate appearances. Bumgarner has been worth 38.1 Wins Above Replacement (33.3 as a pitcher and 4.9 as a hitter) and 20.3 Wins Above Average (15.5 as a pitcher and 4.7 as a hitter).
After adjusting for length of schedule, catchers, and relief pitchers, the 38.1 WAR becomes 37.5 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 20.3 WAA becomes 18.2 adjWAA.
Then, the adjWAR and adjWAA are combined, but with extra weighting given to adjWAA. This gives Bumgarner 70.3 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).
Madison Bumgarner has a Hall Rating of 66, meaning he would not be in the Hall of Stats if his career ended today.
