|About the stats|
Over the course of his career, Aaron Laffey pitched 494 innings and made 9 plate appearances. Laffey was worth 2.4 Wins Above Replacement (2.3 as a pitcher and 0.0 as a hitter) and -2.2 Wins Above Average (-2.3 as a pitcher and 0.0 as a hitter).
After adjusting for length of schedule, catchers, and relief pitchers, the 2.4 WAR becomes 2.5 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 -2.2 WAA becomes 0.0 adjWAA.
Then, the adjWAR and adjWAA are combined, but with extra weighting given to adjWAA. This gives Laffey 2.5 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).
Aaron Laffey has a Hall Rating of 2, leaving him nowhere close to induction to the Hall of Stats.
