|About the stats|
Over the course of his career, Cy Young pitched 7,356 innings and made 3,104 plate appearances. Young was worth 163.7 Wins Above Replacement (165.6 as a pitcher and -2.0 as a hitter) and 99.1 Wins Above Average (101.2 as a pitcher and -2.0 as a hitter).
After adjusting for length of schedule, catchers, and relief pitchers, the 163.7 WAR becomes 162.2 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 99.1 WAA becomes 101.6 adjWAA.
Then, the adjWAR and adjWAA are combined, but with extra weighting given to adjWAA. This gives Young 345.1 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).
Cy Young has a Hall Rating of 324, making him not only a member of the Hall of Stats—but one of the very best players of all time.
