|About the stats|
Over the course of his career, Steve Gromek pitched 2,064 innings and made 743 plate appearances. Gromek was worth 24.9 Wins Above Replacement (22.6 as a pitcher and 2.5 as a hitter) and 9.6 Wins Above Average (7.1 as a pitcher and 2.5 as a hitter).
After adjusting for length of schedule, catchers, and relief pitchers, the 24.9 WAR becomes 26.4 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 9.6 WAA becomes 11.9 adjWAA.
Then, the adjWAR and adjWAA are combined, but with extra weighting given to adjWAA. This gives Gromek 47.8 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).
Steve Gromek has a Hall Rating of 45, leaving him nowhere close to induction to the Hall of Stats.
