|About the stats|
Over the course of his career, Art Herman pitched 112 innings and made 45 plate appearances. Herman was worth 0.3 Wins Above Replacement (0.54 as a pitcher and -0.3 as a hitter) and -0.7 Wins Above Average (-0.434 as a pitcher and -0.3 as a hitter).
After adjusting for length of schedule, catchers, and relief pitchers, the 0.3 WAR becomes 0.3 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 -0.7 WAA becomes 0.0 adjWAA.
Then, the adjWAR and adjWAA are combined, but with extra weighting given to adjWAA. This gives Herman 0.3 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).
Art Herman has a Hall Rating of 0, leaving him nowhere close to induction to the Hall of Stats.
