|About the stats|
Over the course of his career, Johnny Niggeling pitched 1,250 innings and made 466 plate appearances. Niggeling was worth 17.7 Wins Above Replacement (19.7 as a pitcher and -2.0 as a hitter) and 8.3 Wins Above Average (10.3 as a pitcher and -2.0 as a hitter).
After adjusting for length of schedule, catchers, and relief pitchers, the 17.7 WAR becomes 17.8 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 8.3 WAA becomes 13.1 adjWAA.
Then, the adjWAR and adjWAA are combined, but with extra weighting given to adjWAA. This gives Niggeling 41.4 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).
Johnny Niggeling has a Hall Rating of 39, leaving him nowhere close to induction to the Hall of Stats.
