|About the stats|
Over the course of his career, Joe Battin made 1,994 plate appearances and pitched 7 innings. Battin was worth 6.5 Wins Above Replacement (6.4 as a hitter and 0.0 as a pitcher) and 0.5 Wins Above Average (0.7 as a hitter and -0.1 as a pitcher).
After adjusting for length of schedule, catchers, and relief pitchers, the 6.5 WAR becomes 11.1 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 0.5 WAA becomes 4.3 adjWAA.
Then, the adjWAR and adjWAA are combined, but with extra weighting given to adjWAA. This gives Battin 18.8 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 Battin has a Hall Rating of 18, leaving him nowhere close to induction to the Hall of Stats.
