|About the stats|
Over the course of his career, Felix Hernandez pitched 2,729 innings and made 59 plate appearances. Hernandez was worth 49.6 Wins Above Replacement (49.9 as a pitcher and -0.2 as a hitter) and 24.1 Wins Above Average (24.4 as a pitcher and -0.2 as a hitter).
After adjusting for length of schedule, catchers, and relief pitchers, the 49.6 WAR becomes 49.6 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 24.1 WAA becomes 29.2 adjWAA.
Then, the adjWAR and adjWAA are combined, but with extra weighting given to adjWAA. This gives Hernandez 102.2 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).
Felix Hernandez has a Hall Rating of 96, meaning he will not be in the Hall of Stats when eligible—but he will be close.
