Over the course of his career,
Al Jackson
pitched 1,389 innings
and made 478 plate appearances.
Jackson
was worth
5.4 Wins Above Replacement
(5.6 as a pitcher and -0.1 as a hitter)
and -7.2 Wins Above Average
(-7.1 as a pitcher and -0.3 as a hitter).
After adjusting for length of schedule, catchers, and relief pitchers, the 5.4 WAR becomes
5.1 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 -7.2 WAA becomes 2.8 adjWAA.
Then, the adjWAR and adjWAA are combined, but with extra weighting given to adjWAA.
This gives Jackson 10.1 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).
Al Jackson has a Hall Rating of
10,
leaving him nowhere close to induction to the Hall of Stats.
