|About the stats|
So far in his career, Joe Kelly has pitched 767 innings and made 104 plate appearances. Kelly has been worth 5.9 Wins Above Replacement (5.7 as a pitcher and 0.1 as a hitter) and -0.3 Wins Above Average (-0.4 as a pitcher and 0.0 as a hitter).
After adjusting for length of schedule, catchers, and relief pitchers, the 5.9 WAR becomes 6.8 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 -0.3 WAA becomes 3.5 adjWAA.
Then, the adjWAR and adjWAA are combined, but with extra weighting given to adjWAA. This gives Kelly 13.1 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).
Joe Kelly has a Hall Rating of 12, meaning he would not be in the Hall of Stats if his career ended today.
