|About the stats|
Over the course of his career, Jimmy Key pitched 2,591 innings and made 3 plate appearances. Key was worth 49.0 Wins Above Replacement (49.0 as a pitcher and -0.1 as a hitter) and 25.6 Wins Above Average (25.8 as a pitcher and -0.1 as a hitter).
After adjusting for length of schedule, catchers, and relief pitchers, the 49.0 WAR becomes 50.6 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 25.6 WAA becomes 27.1 adjWAA.
Then, the adjWAR and adjWAA are combined, but with extra weighting given to adjWAA. This gives Key 99.4 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).
Jimmy Key has a Hall Rating of 93, making him close to the Hall of Stats borderline—but still on the outside.
