|About the stats|
Over the course of his career, Kevin Gregg pitched 720 innings and made 6 plate appearances. Gregg was worth 4.5 Wins Above Replacement (4.7 as a pitcher and -0.1 as a hitter) and -1.5 Wins Above Average (-1.5 as a pitcher and -0.1 as a hitter).
After adjusting for length of schedule, catchers, and relief pitchers, the 4.5 WAR becomes 5.6 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 -1.5 WAA becomes 2.5 adjWAA.
Then, the adjWAR and adjWAA are combined, but with extra weighting given to adjWAA. This gives Gregg 10.1 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).
Kevin Gregg has a Hall Rating of 9, leaving him nowhere close to induction to the Hall of Stats.
