|About the stats|
Over the course of his career, Joe Spencer made 299 plate appearances. Spencer was worth -1.0 Wins Above Replacement and -2.0 Wins Above Average.
After adjusting for length of schedule, catchers, and relief pitchers, the -1.0 WAR becomes -3.2 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 -2.0 WAA becomes 0.0 adjWAA.
Then, the adjWAR and adjWAA are combined, but with extra weighting given to adjWAA. This gives Spencer -3.2 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 Spencer has a Hall Rating of -3, leaving him nowhere close to induction to the Hall of Stats.
