|About the stats|
Over the course of his career, Tom Hall pitched 852 innings and made 217 plate appearances. Hall was worth 5.9 Wins Above Replacement (6.1 as a pitcher and -0.3 as a hitter) and -1.1 Wins Above Average (-0.8 as a pitcher and -0.3 as a hitter).
After adjusting for length of schedule, catchers, and relief pitchers, the 5.9 WAR becomes 6.7 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 -1.1 WAA becomes 3.6 adjWAA.
Then, the adjWAR and adjWAA are combined, but with extra weighting given to adjWAA. This gives Hall 13.2 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).
Tom Hall has a Hall Rating of 12, leaving him nowhere close to induction to the Hall of Stats.
