|About the stats|
Over the course of his career, Jason Hammel pitched 1,810 innings and made 390 plate appearances. Hammel was worth 13.1 Wins Above Replacement (13.6 as a pitcher and -0.5 as a hitter) and -2.4 Wins Above Average (-1.9 as a pitcher and -0.6 as a hitter).
After adjusting for length of schedule, catchers, and relief pitchers, the 13.1 WAR becomes 13.1 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 -2.4 WAA becomes 5.0 adjWAA.
Then, the adjWAR and adjWAA are combined, but with extra weighting given to adjWAA. This gives Hammel 22.1 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).
Jason Hammel has a Hall Rating of 21, leaving him nowhere close to induction to the Hall of Stats when eligible.
