|About the stats|
Over the course of his career, George Rettger pitched 139 innings and made 75 plate appearances. Rettger was worth 0.0 Wins Above Replacement (0.4 as a pitcher and -0.4 as a hitter) and -1.0 Wins Above Average (-0.6 as a pitcher and -0.4 as a hitter).
After adjusting for length of schedule, catchers, and relief pitchers, the 0.0 WAR becomes -0.1 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 -1.0 WAA becomes 0.0 adjWAA.
Then, the adjWAR and adjWAA are combined, but with extra weighting given to adjWAA. This gives Rettger -0.1 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).
George Rettger has a Hall Rating of 0, leaving him nowhere close to induction to the Hall of Stats.
