|About the stats|
Over the course of his career, Dustin McGowan pitched 650 innings and made 29 plate appearances. McGowan was worth 1.5 Wins Above Replacement (1.9 as a pitcher and -0.3 as a hitter) and -4.3 Wins Above Average (-4.1 as a pitcher and -0.3 as a hitter).
After adjusting for length of schedule, catchers, and relief pitchers, the 1.5 WAR becomes 1.6 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 -4.3 WAA becomes 1.2 adjWAA.
Then, the adjWAR and adjWAA are combined, but with extra weighting given to adjWAA. This gives McGowan 3.8 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).
Dustin McGowan has a Hall Rating of 4, leaving him nowhere close to induction to the Hall of Stats when eligible.
