|About the stats|
Over the course of his career, Pete Alexander pitched 5,190 innings and made 1,981 plate appearances. Alexander was worth 119.2 Wins Above Replacement (116.2 as a pitcher and 3.1 as a hitter) and 78.8 Wins Above Average (75.8 as a pitcher and 3.0 as a hitter).
After adjusting for length of schedule, catchers, and relief pitchers, the 119.2 WAR becomes 123.2 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 78.8 WAA becomes 78.4 adjWAA.
Then, the adjWAR and adjWAA are combined, but with extra weighting given to adjWAA. This gives Alexander 264.3 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).
Pete Alexander has a Hall Rating of 248, making him not only a member of the Hall of Stats—but one of the very best players of all time.
