|About the stats|
Over the course of his career, Joe Grzenda pitched 308 innings and made 34 plate appearances. Grzenda was worth 1.3 Wins Above Replacement (1.47 as a pitcher and -0.2 as a hitter) and -1.6 Wins Above Average (-1.267 as a pitcher and -0.2 as a hitter).
After adjusting for length of schedule, catchers, and relief pitchers, the 1.3 WAR becomes 1.5 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 -1.6 WAA becomes 2.2 adjWAA.
Then, the adjWAR and adjWAA are combined, but with extra weighting given to adjWAA. This gives Grzenda 5.5 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 Grzenda has a Hall Rating of 5, leaving him nowhere close to induction to the Hall of Stats.
