|About the stats|
Over the course of his career, Cannonball Berry pitched 40 innings and made 18 plate appearances. Berry was worth -0.4 Wins Above Replacement (-0.3 as a pitcher and -0.1 as a hitter) and -0.6 Wins Above Average (-0.5 as a pitcher and -0.1 as a hitter).
After adjusting for length of schedule, catchers, and relief pitchers, the -0.4 WAR becomes -0.7 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 -0.6 WAA becomes 0.0 adjWAA.
Then, the adjWAR and adjWAA are combined, but with extra weighting given to adjWAA. This gives Berry -0.7 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).
Cannonball Berry has a Hall Rating of -1, leaving him nowhere close to induction to the Hall of Stats.
