|About the stats|
Over the course of his career, Rollie Sheldon pitched 724 innings and made 239 plate appearances. Sheldon was worth 1.4 Wins Above Replacement (2.9 as a pitcher and -1.5 as a hitter) and -4.6 Wins Above Average (-2.9 as a pitcher and -1.5 as a hitter).
After adjusting for length of schedule, catchers, and relief pitchers, the 1.4 WAR becomes 1.3 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 -4.6 WAA becomes 0.9 adjWAA.
Then, the adjWAR and adjWAA are combined, but with extra weighting given to adjWAA. This gives Sheldon 2.9 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).
Rollie Sheldon has a Hall Rating of 3, leaving him nowhere close to induction to the Hall of Stats.
