|About the stats|
Over the course of his career, Al Atkinson pitched 915 innings and made 424 plate appearances. Atkinson was worth -0.8 Wins Above Replacement (0.2 as a pitcher and -1.0 as a hitter) and -3.7 Wins Above Average (-2.7 as a pitcher and -1.0 as a hitter).
After adjusting for length of schedule, catchers, and relief pitchers, the -0.8 WAR becomes -1.1 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 -3.7 WAA becomes 0.0 adjWAA.
Then, the adjWAR and adjWAA are combined, but with extra weighting given to adjWAA. This gives Atkinson -1.1 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).
Al Atkinson has a Hall Rating of -1, leaving him nowhere close to induction to the Hall of Stats.
