|About the stats|
Over the course of his career, Joe Hatten pitched 1,087 innings and made 389 plate appearances. Hatten was worth 8.1 Wins Above Replacement (9.6 as a pitcher and -1.4 as a hitter) and -2.5 Wins Above Average (-1.2 as a pitcher and -1.5 as a hitter).
After adjusting for length of schedule, catchers, and relief pitchers, the 8.1 WAR becomes 8.6 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 -2.5 WAA becomes 3.6 adjWAA.
Then, the adjWAR and adjWAA are combined, but with extra weighting given to adjWAA. This gives Hatten 15.1 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 Hatten has a Hall Rating of 14, leaving him nowhere close to induction to the Hall of Stats.
