|About the stats|
Over the course of his career, Mickey Welch pitched 4,802 innings and made 2,286 plate appearances. Welch was worth 62.2 Wins Above Replacement (63.1 as a pitcher and -0.8 as a hitter) and 22.8 Wins Above Average (23.9 as a pitcher and -1.3 as a hitter).
After adjusting for length of schedule, catchers, and relief pitchers, the 62.2 WAR becomes 49.9 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 22.8 WAA becomes 25.2 adjWAA.
Then, the adjWAR and adjWAA are combined, but with extra weighting given to adjWAA. This gives Welch 95.3 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).
Mickey Welch has a Hall Rating of 90, leaving him short of induction to the Hall of Stats.
