|About the stats|
Over the course of his career, Phil Niekro pitched 5,404 innings and made 1,707 plate appearances. Niekro was worth 96.0 Wins Above Replacement (97.0 as a pitcher and -1.1 as a hitter) and 49.5 Wins Above Average (50.5 as a pitcher and -1.1 as a hitter).
After adjusting for length of schedule, catchers, and relief pitchers, the 96.0 WAR becomes 98.2 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 49.5 WAA becomes 55.4 adjWAA.
Then, the adjWAR and adjWAA are combined, but with extra weighting given to adjWAA. This gives Niekro 197.9 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).
Phil Niekro has a Hall Rating of 185, making him not only a member of the Hall of Stats—but one of the very best players of all time.
