|About the stats|
Over the course of his career, Alex Kellner pitched 1,849 innings and made 705 plate appearances. Kellner was worth 14.3 Wins Above Replacement (12.5 as a pitcher and 1.5 as a hitter) and -0.6 Wins Above Average (-2.1 as a pitcher and 1.5 as a hitter).
After adjusting for length of schedule, catchers, and relief pitchers, the 14.3 WAR becomes 14.7 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 -0.6 WAA becomes 5.5 adjWAA.
Then, the adjWAR and adjWAA are combined, but with extra weighting given to adjWAA. This gives Kellner 24.6 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).
Alex Kellner has a Hall Rating of 23, leaving him nowhere close to induction to the Hall of Stats.
