|About the stats|
Over the course of his career, John Thornton pitched 290 innings and made 145 plate appearances. Thornton was worth 0.9 Wins Above Replacement (2.0 as a pitcher and -1.1 as a hitter) and -1.6 Wins Above Average (-0.5 as a pitcher and -1.1 as a hitter).
After adjusting for length of schedule, catchers, and relief pitchers, the 0.9 WAR becomes 0.5 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 -1.6 WAA becomes 0.5 adjWAA.
Then, the adjWAR and adjWAA are combined, but with extra weighting given to adjWAA. This gives Thornton 1.4 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).
John Thornton has a Hall Rating of 1, leaving him nowhere close to induction to the Hall of Stats.
