|About the stats|
Over the course of his career, John Harkins pitched 1,183 innings and made 673 plate appearances. Harkins was worth -3.1 Wins Above Replacement (-2.8 as a pitcher and -0.3 as a hitter) and -9.9 Wins Above Average (-9.2 as a pitcher and -0.6 as a hitter).
After adjusting for length of schedule, catchers, and relief pitchers, the -3.1 WAR becomes -2.6 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 -9.9 WAA becomes 0.0 adjWAA.
Then, the adjWAR and adjWAA are combined, but with extra weighting given to adjWAA. This gives Harkins -2.6 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).
John Harkins has a Hall Rating of -2, leaving him nowhere close to induction to the Hall of Stats.
