|About the stats|
Over the course of his career, Roy Sievers made 7,349 plate appearances. Sievers was worth 25.4 Wins Above Replacement and 1.9 Wins Above Average.
After adjusting for length of schedule, catchers, and relief pitchers, the 25.4 WAR becomes 25.9 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 1.9 WAA becomes 10.1 adjWAA.
Then, the adjWAR and adjWAA are combined, but with extra weighting given to adjWAA. This gives Sievers 44.1 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 Sievers has a Hall Rating of 41, leaving him nowhere close to induction to the Hall of Stats.
