|About the stats|
Over the course of his career, Mark Buehrle pitched 3,283 innings and made 140 plate appearances. Buehrle was worth 59.0 Wins Above Replacement (60.0 as a pitcher and -1.0 as a hitter) and 28.3 Wins Above Average (29.3 as a pitcher and -1.0 as a hitter).
After adjusting for length of schedule, catchers, and relief pitchers, the 59.0 WAR becomes 59.2 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 28.3 WAA becomes 30.0 adjWAA.
Then, the adjWAR and adjWAA are combined, but with extra weighting given to adjWAA. This gives Buehrle 113.2 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).
Mark Buehrle has a Hall Rating of 106, making him a member of the Hall of Stats—but one who sits very close to the borderline.
