|About the stats|
Over the course of his career, Buck Ewing made 5,772 plate appearances and pitched 47 innings. Ewing was worth 47.9 Wins Above Replacement (48.0 as a hitter and -0.1 as a pitcher) and 28.1 Wins Above Average (28.5 as a hitter and -0.5 as a pitcher).
After adjusting for length of schedule, catchers, and relief pitchers, the 47.9 WAR becomes 62.9 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 28.1 WAA becomes 33.8 adjWAA.
Then, the adjWAR and adjWAA are combined, but with extra weighting given to adjWAA. This gives Ewing 123.7 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).
Buck Ewing has a Hall Rating of 116, making him a member of the Hall of Stats.
