|About the stats|
Over the course of his career, Bill Hallman made 6,643 plate appearances and pitched 2 innings. Hallman was worth 7.1 Wins Above Replacement (7.2 as a hitter and -0.2 as a pitcher) and -14.6 Wins Above Average (-14.3 as a hitter and -0.2 as a pitcher).
After adjusting for length of schedule, catchers, and relief pitchers, the 7.1 WAR becomes 7.5 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 -14.6 WAA becomes 0.5 adjWAA.
Then, the adjWAR and adjWAA are combined, but with extra weighting given to adjWAA. This gives Hallman 8.4 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).
Bill Hallman has a Hall Rating of 8, leaving him nowhere close to induction to the Hall of Stats.
