|About the stats|
Over the course of his career, Mike Pelfrey pitched 1,476 innings and made 308 plate appearances. Pelfrey was worth 5.8 Wins Above Replacement (6.5 as a pitcher and -0.8 as a hitter) and -6.6 Wins Above Average (-5.9 as a pitcher and -0.8 as a hitter).
After adjusting for length of schedule, catchers, and relief pitchers, the 5.8 WAR becomes 5.7 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 -6.6 WAA becomes 3.4 adjWAA.
Then, the adjWAR and adjWAA are combined, but with extra weighting given to adjWAA. This gives Pelfrey 11.8 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).
Mike Pelfrey has a Hall Rating of 11, leaving him nowhere close to induction to the Hall of Stats when eligible.
