|About the stats|
Over the course of his career, Rollie Fingers pitched 1,701 innings and made 201 plate appearances. Fingers was worth 25.5 Wins Above Replacement (25.0 as a pitcher and 0.6 as a hitter) and 7.5 Wins Above Average (7.0 as a pitcher and 0.6 as a hitter).
After adjusting for length of schedule, catchers, and relief pitchers, the 25.5 WAR becomes 32.7 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 7.5 WAA becomes 13.1 adjWAA.
Then, the adjWAR and adjWAA are combined, but with extra weighting given to adjWAA. This gives Fingers 56.3 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).
Rollie Fingers has a Hall Rating of 53, leaving him nowhere close to induction to the Hall of Stats.
