Over the course of his career,
Billy Pierce
pitched 3,306 innings
and made 1,255 plate appearances.
Pierce was worth 50.4 Wins Above Replacement
(50.0 as a pitcher and 0.4 as a hitter)
and 26.4 Wins Above Average
(26.2 as a pitcher and 0.3 as a hitter).
After adjusting for length of schedule, catchers, and relief pitchers, the 50.4 WAR becomes
52.0 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 26.4 WAA becomes 29.5 adjWAA.
Then, the adjWAR and adjWAA are combined, but with extra weighting given to adjWAA.
This gives Pierce 101.9 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).
Billy Pierce has a Hall Rating of 101,
making him a member of the Hall of Stats—but one who sits very close to the borderline.
