Over the course of his career,
Carl Yastrzemski
made 13,992 plate appearances.
Yastrzemski was worth 90.1 Wins Above Replacement
and 50.1 Wins Above Average.
After adjusting for length of schedule, catchers, and relief pitchers, the 90.1 WAR becomes
90.2 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 50.1 WAA becomes 55.5 adjWAA.
Then, the adjWAR and adjWAA are combined, but with extra weighting given to adjWAA.
This gives Yastrzemski 184.1 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 182,
making him not only a member of the Hall of Stats—but one of the very best players of all time.
