Over the course of his career,
Bob Gibson
pitched 3,884 innings
and made 1,489 plate appearances.
Gibson was worth 85.3 Wins Above Replacement
(77.5 as a pitcher and 7.8 as a hitter)
and 54.9 Wins Above Average
(47.0 as a pitcher and 8.0 as a hitter).
After adjusting for length of schedule, catchers, and relief pitchers, the 85.3 WAR becomes
86.0 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 54.9 WAA becomes 50.5 adjWAA.
Then, the adjWAR and adjWAA are combined, but with extra weighting given to adjWAA.
This gives Gibson 171.4 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).
Bob Gibson has a Hall Rating of 169,
making him a member of the Hall of Stats.
