|About the stats|
Over the course of his career, Mike Williams pitched 768 innings and made 136 plate appearances. Williams was worth 3.3 Wins Above Replacement (3.6 as a pitcher and -0.2 as a hitter) and -2.1 Wins Above Average (-1.9 as a pitcher and -0.2 as a hitter).
After adjusting for length of schedule, catchers, and relief pitchers, the 3.3 WAR becomes 4.5 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 -2.1 WAA becomes 4.4 adjWAA.
Then, the adjWAR and adjWAA are combined, but with extra weighting given to adjWAA. This gives Williams 12.4 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).
Mike Williams has a Hall Rating of 12, leaving him nowhere close to induction to the Hall of Stats.
