|About the stats|
Over the course of his career, Jim Palmer pitched 3,948 innings and made 537 plate appearances. Palmer was worth 68.6 Wins Above Replacement (67.6 as a pitcher and 0.9 as a hitter) and 33.3 Wins Above Average (32.2 as a pitcher and 0.9 as a hitter).
After adjusting for length of schedule, catchers, and relief pitchers, the 68.6 WAR becomes 69.4 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 33.3 WAA becomes 35.9 adjWAA.
Then, the adjWAR and adjWAA are combined, but with extra weighting given to adjWAA. This gives Palmer 134.0 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).
Jim Palmer has a Hall Rating of 126, making him a member of the Hall of Stats.
