|About the stats|
Over the course of his career, Don Carman pitched 921 innings and made 239 plate appearances. Carman was worth 5.3 Wins Above Replacement (7.6 as a pitcher and -2.3 as a hitter) and -3.2 Wins Above Average (-1.0 as a pitcher and -2.3 as a hitter).
After adjusting for length of schedule, catchers, and relief pitchers, the 5.3 WAR becomes 6.1 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 -3.2 WAA becomes 4.1 adjWAA.
Then, the adjWAR and adjWAA are combined, but with extra weighting given to adjWAA. This gives Carman 13.5 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).
Don Carman has a Hall Rating of 13, leaving him nowhere close to induction to the Hall of Stats.
