|About the stats|
Over the course of his career, Hippo Vaughn pitched 2,730 innings and made 1,016 plate appearances. Vaughn was worth 47.0 Wins Above Replacement (47.1 as a pitcher and -0.3 as a hitter) and 24.9 Wins Above Average (25.2 as a pitcher and -0.3 as a hitter).
After adjusting for length of schedule, catchers, and relief pitchers, the 47.0 WAR becomes 50.2 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 24.9 WAA becomes 29.6 adjWAA.
Then, the adjWAR and adjWAA are combined, but with extra weighting given to adjWAA. This gives Vaughn 103.5 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).
Hippo Vaughn has a Hall Rating of 97, making him close to the Hall of Stats borderline—but still on the outside.
