|About the stats|
Over the course of his career, Marty Bystrom pitched 435 innings and made 125 plate appearances. Bystrom was worth 1.9 Wins Above Replacement (1.9 as a pitcher and 0.0 as a hitter) and -1.9 Wins Above Average (-1.9 as a pitcher and 0.0 as a hitter).
After adjusting for length of schedule, catchers, and relief pitchers, the 1.9 WAR becomes 2.5 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 -1.9 WAA becomes 2.5 adjWAA.
Then, the adjWAR and adjWAA are combined, but with extra weighting given to adjWAA. This gives Bystrom 6.9 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).
Marty Bystrom has a Hall Rating of 6, leaving him nowhere close to induction to the Hall of Stats.
