Over the course of his career,
Grant Jackson
pitched 1,358 innings
and made 252 plate appearances.
Jackson
was worth
13.9 Wins Above Replacement
(14.1 as a pitcher and -0.1 as a hitter)
and 1.1 Wins Above Average
(1.0 as a pitcher and -0.1 as a hitter).
After adjusting for length of schedule, catchers, and relief pitchers, the 13.9 WAR becomes
16.4 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 1.1 WAA becomes 7.1 adjWAA.
Then, the adjWAR and adjWAA are combined, but with extra weighting given to adjWAA.
This gives Jackson 29.2 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).
Grant Jackson has a Hall Rating of
27,
leaving him nowhere close to induction to the Hall of Stats.
