|About the stats|
Over the course of his career, Bob Black made 156 plate appearances and pitched 123 innings. Black was worth 0.4 Wins Above Replacement (0.5 as a hitter and -0.2 as a pitcher) and 0.6 Wins Above Average (0.5 as a hitter and 0.1 as a pitcher).
After adjusting for length of schedule, catchers, and relief pitchers, the 0.4 WAR becomes 0.7 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 0.0 adjWAA.
Then, the adjWAR and adjWAA are combined, but with extra weighting given to adjWAA. This gives Black 0.7 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).
Bob Black has a Hall Rating of 1, leaving him nowhere close to induction to the Hall of Stats.
