|About the stats|
Over the course of his career, Mike Maroth pitched 918 innings and made 36 plate appearances. Maroth was worth 4.0 Wins Above Replacement (3.7 as a pitcher and 0.3 as a hitter) and -4.8 Wins Above Average (-5.2 as a pitcher and 0.3 as a hitter).
After adjusting for length of schedule, catchers, and relief pitchers, the 4.0 WAR becomes 3.9 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 -4.8 WAA becomes 1.9 adjWAA.
Then, the adjWAR and adjWAA are combined, but with extra weighting given to adjWAA. This gives Maroth 7.3 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).
Mike Maroth has a Hall Rating of 7, leaving him nowhere close to induction to the Hall of Stats.
