|About the stats|
Over the course of his career, Pud Galvin pitched 6,003 innings and made 2,788 plate appearances. Galvin was worth 73.5 Wins Above Replacement (83.3 as a pitcher and -9.8 as a hitter) and 26.4 Wins Above Average (36.5 as a pitcher and -10.1 as a hitter).
After adjusting for length of schedule, catchers, and relief pitchers, the 73.5 WAR becomes 54.6 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 26.4 WAA becomes 34.1 adjWAA.
Then, the adjWAR and adjWAA are combined, but with extra weighting given to adjWAA. This gives Galvin 116.0 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).
Pud Galvin has a Hall Rating of 109, making him a member of the Hall of Stats—but one who sits very close to the borderline.
