|About the stats|
Over the course of his career, Harry Jeffries made 2,098 plate appearances and pitched 1 innings. Jeffries was worth 0.8 Wins Above Replacement (0.7 as a hitter and 0.0 as a pitcher) and -6.1 Wins Above Average (-6.3 as a hitter and 0.0 as a pitcher).
After adjusting for length of schedule, catchers, and relief pitchers, the 0.8 WAR becomes 1.8 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 -6.1 WAA becomes 1.2 adjWAA.
Then, the adjWAR and adjWAA are combined, but with extra weighting given to adjWAA. This gives Jeffries 4.0 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).
Harry Jeffries has a Hall Rating of 4, leaving him nowhere close to induction to the Hall of Stats.
