|About the stats|
Over the course of his career, Ryne Duren pitched 589 innings and made 138 plate appearances. Duren was worth 4.9 Wins Above Replacement (5.7 as a pitcher and -0.8 as a hitter) and -1.6 Wins Above Average (-0.8 as a pitcher and -0.8 as a hitter).
After adjusting for length of schedule, catchers, and relief pitchers, the 4.9 WAR becomes 6.1 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 -1.6 WAA becomes 4.0 adjWAA.
Then, the adjWAR and adjWAA are combined, but with extra weighting given to adjWAA. This gives Duren 13.3 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).
Ryne Duren has a Hall Rating of 12, leaving him nowhere close to induction to the Hall of Stats.
