|About the stats|
Over the course of his career, Carl Yastrzemski made 13,992 plate appearances. Yastrzemski was worth 96.5 Wins Above Replacement and 50.3 Wins Above Average.
After adjusting for length of schedule, catchers, and relief pitchers, the 96.5 WAR becomes 96.9 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 50.3 WAA becomes 55.8 adjWAA.
Then, the adjWAR and adjWAA are combined, but with extra weighting given to adjWAA. This gives Yastrzemski 197.3 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).
Carl Yastrzemski 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.
