|About the stats|
Over the course of his career, Al Nipper pitched 797 innings and made 25 plate appearances. Nipper was worth 5.4 Wins Above Replacement (5.5 as a pitcher and -0.2 as a hitter) and -1.6 Wins Above Average (-1.5 as a pitcher and -0.2 as a hitter).
After adjusting for length of schedule, catchers, and relief pitchers, the 5.4 WAR becomes 5.5 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 -1.6 WAA becomes 2.8 adjWAA.
Then, the adjWAR and adjWAA are combined, but with extra weighting given to adjWAA. This gives Nipper 10.5 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).
Al Nipper has a Hall Rating of 10, leaving him nowhere close to induction to the Hall of Stats.
