|About the stats|
Over the course of his career, Matt Koch pitched 129 innings and made 35 plate appearances. Koch was worth 0.6 Wins Above Replacement (0.7 as a pitcher and 0.0 as a hitter) and -0.8 Wins Above Average (-0.7 as a pitcher and 0.0 as a hitter).
After adjusting for length of schedule, catchers, and relief pitchers, the 0.6 WAR becomes 0.8 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 -0.8 WAA becomes 0.9 adjWAA.
Then, the adjWAR and adjWAA are combined, but with extra weighting given to adjWAA. This gives Koch 2.4 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).
Matt Koch has a Hall Rating of 2, leaving him nowhere close to induction to the Hall of Stats when eligible.
