Over the course of his career,
Mickey Haefner
pitched 1,466 innings
and made 540 plate appearances.
Haefner
was worth
17.4 Wins Above Replacement
(15.7 as a pitcher and 1.7 as a hitter)
and 6.8 Wins Above Average
(4.9 as a pitcher and 1.7 as a hitter).
After adjusting for length of schedule, catchers, and relief pitchers, the 17.4 WAR becomes
18.3 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 6.8 WAA becomes 7.0 adjWAA.
Then, the adjWAR and adjWAA are combined, but with extra weighting given to adjWAA.
This gives Haefner 30.9 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).
Mickey Haefner has a Hall Rating of
29,
leaving him nowhere close to induction to the Hall of Stats.
