|About the stats|
Over the course of his career, Eddie Plank pitched 4,489 innings and made 1,772 plate appearances. Plank was worth 90.9 Wins Above Replacement (87.7 as a pitcher and 3.3 as a hitter) and 51.4 Wins Above Average (48.2 as a pitcher and 3.2 as a hitter).
After adjusting for length of schedule, catchers, and relief pitchers, the 90.9 WAR becomes 93.3 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 51.4 WAA becomes 49.4 adjWAA.
Then, the adjWAR and adjWAA are combined, but with extra weighting given to adjWAA. This gives Plank 182.3 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).
Eddie Plank has a Hall Rating of 171, making him a member of the Hall of Stats.
