|About the stats|
Over the course of his career, George Derby pitched 964 innings and made 455 plate appearances. Derby was worth 4.8 Wins Above Replacement (6.7 as a pitcher and -1.9 as a hitter) and -3.5 Wins Above Average (-1.5 as a pitcher and -2.0 as a hitter).
After adjusting for length of schedule, catchers, and relief pitchers, the 4.8 WAR becomes 2.7 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 -3.5 WAA becomes 3.5 adjWAA.
Then, the adjWAR and adjWAA are combined, but with extra weighting given to adjWAA. This gives Derby 9.0 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).
George Derby has a Hall Rating of 8, leaving him nowhere close to induction to the Hall of Stats.
