|About the stats|
So far in his career, Danny Duffy has pitched 1,172 innings and made 24 plate appearances. Duffy has been worth 20.5 Wins Above Replacement (20.3 as a pitcher and 0.0 as a hitter) and 9.5 Wins Above Average (9.6 as a pitcher and 0.0 as a hitter).
After adjusting for length of schedule, catchers, and relief pitchers, the 20.5 WAR becomes 21.5 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 9.5 WAA becomes 11.2 adjWAA.
Then, the adjWAR and adjWAA are combined, but with extra weighting given to adjWAA. This gives Duffy 41.7 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).
Danny Duffy has a Hall Rating of 39, meaning he would not be in the Hall of Stats if his career ended today.
