|About the stats|
Over the course of his career, Joe Sparks made 378 plate appearances and pitched 2 innings. Sparks was worth -0.2 Wins Above Replacement (0.1 as a hitter and -0.2 as a pitcher) and -1.4 Wins Above Average (-1.1 as a hitter and -0.3 as a pitcher).
After adjusting for length of schedule, catchers, and relief pitchers, the -0.2 WAR becomes 0.5 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 -1.4 WAA becomes 0.1 adjWAA.
Then, the adjWAR and adjWAA are combined, but with extra weighting given to adjWAA. This gives Sparks 0.7 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).
Joe Sparks has a Hall Rating of 1, leaving him nowhere close to induction to the Hall of Stats.
