|About the stats|
Over the course of his career, Jack Harper pitched 1,216 innings and made 505 plate appearances. Harper was worth 4.9 Wins Above Replacement (5.0 as a pitcher and -0.1 as a hitter) and -4.7 Wins Above Average (-4.8 as a pitcher and -0.1 as a hitter).
After adjusting for length of schedule, catchers, and relief pitchers, the 4.9 WAR becomes 5.0 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 -4.7 WAA becomes 2.7 adjWAA.
Then, the adjWAR and adjWAA are combined, but with extra weighting given to adjWAA. This gives Harper 9.9 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).
Jack Harper has a Hall Rating of 9, leaving him nowhere close to induction to the Hall of Stats.
