|About the stats|
Over the course of his career, Andy Boswell pitched 64 innings and made 33 plate appearances. Boswell was worth -0.8 Wins Above Replacement (-0.7 as a pitcher and -0.1 as a hitter) and -1.4 Wins Above Average (-1.2 as a pitcher and -0.1 as a hitter).
After adjusting for length of schedule, catchers, and relief pitchers, the -0.8 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 -1.4 WAA becomes 0.0 adjWAA.
Then, the adjWAR and adjWAA are combined, but with extra weighting given to adjWAA. This gives Boswell -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).
Andy Boswell has a Hall Rating of -1, leaving him nowhere close to induction to the Hall of Stats.
