Over the course of his career,
Joe Nathan
pitched 923 innings
and made 77 plate appearances.
Nathan
was worth
26.7 Wins Above Replacement
(26.4 as a pitcher and 0.3 as a hitter)
and 14.3 Wins Above Average
(14.0 as a pitcher and 0.3 as a hitter).
After adjusting for length of schedule, catchers, and relief pitchers, the 26.7 WAR becomes
31.7 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 14.3 WAA becomes 18.6 adjWAA.
Then, the adjWAR and adjWAA are combined, but with extra weighting given to adjWAA.
This gives Nathan 65.2 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).
Joe Nathan has a Hall Rating of
61,
leaving him short of induction to the Hall of Stats.
