Over the course of his career,
Rats Henderson
pitched 1,058 innings
and made 466 plate appearances.
Henderson
was worth
21.0 Wins Above Replacement
(21.8 as a pitcher and -1.0 as a hitter)
and 12.0 Wins Above Average
(13.1 as a pitcher and -1.0 as a hitter).
After adjusting for length of schedule, catchers, and relief pitchers, the 21.0 WAR becomes
20.8 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 12.0 WAA becomes 14.7 adjWAA.
Then, the adjWAR and adjWAA are combined, but with extra weighting given to adjWAA.
This gives Henderson 47.3 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).
Rats Henderson has a Hall Rating of
44,
leaving him nowhere close to induction to the Hall of Stats.
