|About the stats|
Over the course of his career, Gil Hatfield made 1,322 plate appearances and pitched 77 innings. Hatfield was worth -1.4 Wins Above Replacement (-0.2 as a hitter and -1.3 as a pitcher) and -5.5 Wins Above Average (-3.7 as a hitter and -1.8 as a pitcher).
After adjusting for length of schedule, catchers, and relief pitchers, the -1.4 WAR becomes -1.4 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 -5.5 WAA becomes 0.3 adjWAA.
Then, the adjWAR and adjWAA are combined, but with extra weighting given to adjWAA. This gives Hatfield -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).
Gil Hatfield has a Hall Rating of -1, leaving him nowhere close to induction to the Hall of Stats.
