|About the stats|
Over the course of his career, Art Watson made 101 plate appearances. Watson was worth 0.3 Wins Above Replacement and 0.2 Wins Above Average.
After adjusting for length of schedule, catchers, and relief pitchers, the 0.3 WAR becomes 0.3 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 0.2 WAA becomes 0.0 adjWAA.
Then, the adjWAR and adjWAA are combined, but with extra weighting given to adjWAA. This gives Watson 0.3 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).
Art Watson has a Hall Rating of 0, leaving him nowhere close to induction to the Hall of Stats.
