|About the stats|
Over the course of his career, Babe Ruth made 10,626 plate appearances and pitched 1,221 innings. Ruth was worth 183.3 Wins Above Replacement (162.7 as a hitter and 20.4 as a pitcher) and 134.3 Wins Above Average (125.3 as a hitter and 9.1 as a pitcher).
After adjusting for length of schedule, catchers, and relief pitchers, the 183.3 WAR becomes 189.1 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 134.3 WAA becomes 130.8 adjWAA.
Then, the adjWAR and adjWAA are combined, but with extra weighting given to adjWAA. This gives Ruth 424.5 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).
Babe Ruth has a Hall Rating of 399, making him not only a member of the Hall of Stats—but the very best player of all time.
