|About the stats|
Over the course of his career, Joe Sewell made 8,333 plate appearances. Sewell was worth 54.8 Wins Above Replacement and 23.5 Wins Above Average.
After adjusting for length of schedule, catchers, and relief pitchers, the 54.8 WAR becomes 56.4 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 23.5 WAA becomes 23.6 adjWAA.
Then, the adjWAR and adjWAA are combined, but with extra weighting given to adjWAA. This gives Sewell 98.9 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 Sewell has a Hall Rating of 93, making him close to the Hall of Stats borderline—but still on the outside.
