|About the stats|
Over the course of his career, Jim McCormick pitched 4,275 innings and made 2,104 plate appearances. McCormick was worth 76.3 Wins Above Replacement (76.0 as a pitcher and 0.2 as a hitter) and 43.0 Wins Above Average (43.1 as a pitcher and -0.3 as a hitter).
After adjusting for length of schedule, catchers, and relief pitchers, the 76.3 WAR becomes 61.1 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 43.0 WAA becomes 28.9 adjWAA.
Then, the adjWAR and adjWAA are combined, but with extra weighting given to adjWAA. This gives McCormick 113.1 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).
Jim McCormick has a Hall Rating of 106, making him a member of the Hall of Stats—but one who sits very close to the borderline.
