|About the stats|
Over the course of his career, Jack Quinn pitched 3,920 innings and made 1,513 plate appearances. Quinn was worth 58.8 Wins Above Replacement (59.8 as a pitcher and -1.1 as a hitter) and 23.9 Wins Above Average (25.2 as a pitcher and -1.1 as a hitter).
After adjusting for length of schedule, catchers, and relief pitchers, the 58.8 WAR becomes 63.1 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 23.9 WAA becomes 30.4 adjWAA.
Then, the adjWAR and adjWAA are combined, but with extra weighting given to adjWAA. This gives Quinn 117.8 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).
Jack Quinn has a Hall Rating of 110, making him a member of the Hall of Stats.
