|About the stats|
Over the course of his career, Curt Welch made 4,939 plate appearances and pitched 1 innings. Welch was worth 20.2 Wins Above Replacement (20.5 as a hitter and -0.3 as a pitcher) and 8.4 Wins Above Average (8.7 as a hitter and -0.3 as a pitcher).
After adjusting for length of schedule, catchers, and relief pitchers, the 20.2 WAR becomes 21.9 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 8.4 WAA becomes 11.3 adjWAA.
Then, the adjWAR and adjWAA are combined, but with extra weighting given to adjWAA. This gives Welch 42.2 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).
Curt Welch has a Hall Rating of 40, leaving him nowhere close to induction to the Hall of Stats.
