|About the stats|
Over the course of his career, Jeff Parrett pitched 724 innings and made 43 plate appearances. Parrett was worth 5.5 Wins Above Replacement (5.5 as a pitcher and -0.1 as a hitter) and -0.4 Wins Above Average (-0.2 as a pitcher and -0.1 as a hitter).
After adjusting for length of schedule, catchers, and relief pitchers, the 5.5 WAR becomes 6.6 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 -0.4 WAA becomes 3.0 adjWAA.
Then, the adjWAR and adjWAA are combined, but with extra weighting given to adjWAA. This gives Parrett 12.0 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).
Jeff Parrett has a Hall Rating of 11, leaving him nowhere close to induction to the Hall of Stats.
