Over the course of his career,
Roy Campanella
made 5,647 plate appearances
and pitched 15 innings.
Campanella
was worth
41.7 Wins Above Replacement
(41.8 as a hitter and -0.2 as a pitcher)
and 20.6 Wins Above Average
(20.9 as a hitter and -0.3 as a pitcher).
After adjusting for length of schedule, catchers, and relief pitchers, the 41.7 WAR becomes
58.8 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 20.6 WAA becomes 30.4 adjWAA.
Then, the adjWAR and adjWAA are combined, but with extra weighting given to adjWAA.
This gives Campanella 113.5 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).
Roy Campanella has a Hall Rating of
107,
making him a member of the Hall of Stats—but one who sits very close to the borderline.
