|About the stats|
So far in his career, Brad Keller has pitched 633 innings and made 20 plate appearances. Keller has been worth 9.0 Wins Above Replacement (9.0 as a pitcher and 0.0 as a hitter) and 3.3 Wins Above Average (3.3 as a pitcher and 0.0 as a hitter).
After adjusting for length of schedule, catchers, and relief pitchers, the 9.0 WAR becomes 12.5 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 3.3 WAA becomes 5.9 adjWAA.
Then, the adjWAR and adjWAA are combined, but with extra weighting given to adjWAA. This gives Keller 23.1 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).
Brad Keller has a Hall Rating of 22, meaning he would not be in the Hall of Stats if his career ended today.
