|About the stats|
Over the course of his career, John Fitzgerald pitched 32 innings and made 14 plate appearances. Fitzgerald was worth -1.0 Wins Above Replacement (-0.8 as a pitcher and -0.2 as a hitter) and -1.2 Wins Above Average (-1.0 as a pitcher and -0.2 as a hitter).
After adjusting for length of schedule, catchers, and relief pitchers, the -1.0 WAR becomes -0.9 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 -1.2 WAA becomes 0.0 adjWAA.
Then, the adjWAR and adjWAA are combined, but with extra weighting given to adjWAA. This gives Fitzgerald -0.9 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).
John Fitzgerald has a Hall Rating of -1, leaving him nowhere close to induction to the Hall of Stats.
