Over the course of his career,
Bill Foster
pitched 1,499 innings
and made 644 plate appearances.
Foster
was worth
47.1 Wins Above Replacement
(45.6 as a pitcher and 1.5 as a hitter)
and 34.5 Wins Above Average
(33.4 as a pitcher and 1.3 as a hitter).
After adjusting for length of schedule, catchers, and relief pitchers, the 47.1 WAR becomes
51.1 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 34.5 WAA becomes 34.6 adjWAA.
Then, the adjWAR and adjWAA are combined, but with extra weighting given to adjWAA.
This gives Foster 113.4 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).
Bill Foster has a Hall Rating of
107,
making him a member of the Hall of Stats—but one who sits very close to the borderline.
