|About the stats|
Over the course of his career, Noodles Hahn pitched 2,029 innings and made 813 plate appearances. Hahn was worth 44.5 Wins Above Replacement (46.0 as a pitcher and -1.4 as a hitter) and 28.3 Wins Above Average (29.6 as a pitcher and -1.4 as a hitter).
After adjusting for length of schedule, catchers, and relief pitchers, the 44.5 WAR becomes 44.7 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 28.3 WAA becomes 30.7 adjWAA.
Then, the adjWAR and adjWAA are combined, but with extra weighting given to adjWAA. This gives Hahn 100.0 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).
Noodles Hahn has a Hall Rating of 94, making him close to the Hall of Stats borderline—but still on the outside.
