Over the course of his career,
Sumner Bowman
pitched 146 innings
and made 100 plate appearances.
Bowman
was worth
-2.0 Wins Above Replacement
(-2.2 as a pitcher and 0.2 as a hitter)
and -3.1 Wins Above Average
(-3.2 as a pitcher and 0.1 as a hitter).
After adjusting for length of schedule, catchers, and relief pitchers, the -2.0 WAR becomes
-1.7 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 -3.1 WAA becomes 0.0 adjWAA.
Then, the adjWAR and adjWAA are combined, but with extra weighting given to adjWAA.
This gives Bowman -1.7 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).
Sumner Bowman has a Hall Rating of
-2,
leaving him nowhere close to induction to the Hall of Stats.
