Over the course of his career,
Sandy Koufax
pitched 2,324 innings
and made 858 plate appearances.
Koufax
was worth
48.8 Wins Above Replacement
(53.1 as a pitcher and -4.2 as a hitter)
and 26.4 Wins Above Average
(30.6 as a pitcher and -4.2 as a hitter).
After adjusting for length of schedule, catchers, and relief pitchers, the 48.8 WAR becomes
49.7 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 26.4 WAA becomes 32.5 adjWAA.
Then, the adjWAR and adjWAA are combined, but with extra weighting given to adjWAA.
This gives Koufax 108.2 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).
Sandy Koufax has a Hall Rating of
102,
making him a member of the Hall of Stats—but one who sits very close to the borderline.
