|About the stats|
Over the course of his career, Charlie Buffinton pitched 3,404 innings and made 2,309 plate appearances. Buffinton was worth 60.8 Wins Above Replacement (60.7 as a pitcher and 0.0 as a hitter) and 32.4 Wins Above Average (34.8 as a pitcher and -2.4 as a hitter).
After adjusting for length of schedule, catchers, and relief pitchers, the 60.8 WAR becomes 48.5 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 32.4 WAA becomes 33.7 adjWAA.
Then, the adjWAR and adjWAA are combined, but with extra weighting given to adjWAA. This gives Buffinton 109.2 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).
Charlie Buffinton has a Hall Rating of 103, making him a member of the Hall of Stats—but one who sits very close to the borderline.
