|About the stats|
Over the course of his career, Johan Santana pitched 2,025 innings and made 279 plate appearances. Santana was worth 51.9 Wins Above Replacement (51.1 as a pitcher and 0.6 as a hitter) and 33.4 Wins Above Average (32.8 as a pitcher and 0.6 as a hitter).
After adjusting for length of schedule, catchers, and relief pitchers, the 51.9 WAR becomes 52.6 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 33.4 WAA becomes 34.8 adjWAA.
Then, the adjWAR and adjWAA are combined, but with extra weighting given to adjWAA. This gives Santana 115.2 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).
Johan Santana has a Hall Rating of 108, making him a member of the Hall of Stats—but one who sits very close to the borderline.
