Over the course of his career,
Kevin Appier
pitched 2,595 innings
and made 90 plate appearances.
Appier was worth 51.5 Wins Above Replacement
(51.9 as a pitcher and -0.4 as a hitter)
and 30.3 Wins Above Average
(30.7 as a pitcher and -0.4 as a hitter).
After adjusting for length of schedule, catchers, and relief pitchers, the 51.5 WAR becomes
53.9 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 30.3 WAA becomes 34.6 adjWAA.
Then, the adjWAR and adjWAA are combined, but with extra weighting given to adjWAA.
This gives Appier 112.4 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).
Kevin Appier has a Hall Rating of 111,
making him a member of the Hall of Stats.
