|About the stats|
Over the course of his career, Craig Lefferts pitched 1,145 innings and made 147 plate appearances. Lefferts was worth 9.0 Wins Above Replacement (9.4 as a pitcher and -0.5 as a hitter) and -0.7 Wins Above Average (-0.2 as a pitcher and -0.5 as a hitter).
After adjusting for length of schedule, catchers, and relief pitchers, the 9.0 WAR becomes 10.9 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 -0.7 WAA becomes 5.1 adjWAA.
Then, the adjWAR and adjWAA are combined, but with extra weighting given to adjWAA. This gives Lefferts 20.1 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).
Craig Lefferts has a Hall Rating of 19, leaving him nowhere close to induction to the Hall of Stats.
