Over the course of his career,
Art Mahaffey
pitched 999 innings
and made 360 plate appearances.
Mahaffey
was worth
7.4 Wins Above Replacement
(7.7 as a pitcher and -0.4 as a hitter)
and -2.6 Wins Above Average
(-2.3 as a pitcher and -0.4 as a hitter).
After adjusting for length of schedule, catchers, and relief pitchers, the 7.4 WAR becomes
7.2 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 -2.6 WAA becomes 3.6 adjWAA.
Then, the adjWAR and adjWAA are combined, but with extra weighting given to adjWAA.
This gives Mahaffey 13.7 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).
Art Mahaffey has a Hall Rating of
13,
leaving him nowhere close to induction to the Hall of Stats.
