|About the stats|
So far in his career, J.A. Happ has pitched 1,893 innings and made 253 plate appearances. Happ has been worth 20.9 Wins Above Replacement (21.5 as a pitcher and -0.4 as a hitter) and 4.9 Wins Above Average (5.1 as a pitcher and -0.4 as a hitter).
After adjusting for length of schedule, catchers, and relief pitchers, the 20.9 WAR becomes 23.3 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 4.9 WAA becomes 13.1 adjWAA.
Then, the adjWAR and adjWAA are combined, but with extra weighting given to adjWAA. This gives Happ 46.9 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).
J.A. Happ has a Hall Rating of 44, meaning he would not be in the Hall of Stats if his career ended today.
