|About the stats|
Over the course of his career, Mark Fidrych pitched 412 innings. Fidrych was worth 11.3 Wins Above Replacement and 7.6 Wins Above Average.
After adjusting for length of schedule, catchers, and relief pitchers, the 11.3 WAR becomes 11.5 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 7.6 WAA becomes 9.5 adjWAA.
Then, the adjWAR and adjWAA are combined, but with extra weighting given to adjWAA. This gives Fidrych 28.6 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).
Mark Fidrych has a Hall Rating of 26, leaving him nowhere close to induction to the Hall of Stats.
