Over the course of his career,
Jud Birchall
made 1,044 plate appearances.
Birchall
was worth
-1.3 Wins Above Replacement
and -3.7 Wins Above Average.
After adjusting for length of schedule, catchers, and relief pitchers, the -1.3 WAR becomes
-1.8 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 -3.7 WAA becomes 0.0 adjWAA.
Then, the adjWAR and adjWAA are combined, but with extra weighting given to adjWAA.
This gives Birchall -1.8 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).
Jud Birchall has a Hall Rating of
-2,
leaving him nowhere close to induction to the Hall of Stats.
