|About the stats|
Over the course of his career, Ted Williams made 9,792 plate appearances and pitched 2 innings. Williams was worth 121.9 Wins Above Replacement (122.0 as a hitter and 0.0 as a pitcher) and 92.7 Wins Above Average (92.7 as a hitter and 0.0 as a pitcher).
After adjusting for length of schedule, catchers, and relief pitchers, the 121.9 WAR becomes 124.9 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 92.7 WAA becomes 93.8 adjWAA.
Then, the adjWAR and adjWAA are combined, but with extra weighting given to adjWAA. This gives Williams 293.7 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).
Ted Williams has a Hall Rating of 276, making him not only a member of the Hall of Stats—but one of the very best players of all time.
