|About the stats|
Over the course of his career, Joe Royal made 119 plate appearances and pitched 6 innings. Royal was worth -0.8 Wins Above Replacement (-0.6 as a hitter and -0.2 as a pitcher) and -1.3 Wins Above Average (-1.0 as a hitter and -0.3 as a pitcher).
After adjusting for length of schedule, catchers, and relief pitchers, the -0.8 WAR becomes -3.0 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 -1.3 WAA becomes 0.0 adjWAA.
Then, the adjWAR and adjWAA are combined, but with extra weighting given to adjWAA. This gives Royal -3.0 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).
Joe Royal has a Hall Rating of -3, leaving him nowhere close to induction to the Hall of Stats.
