|About the stats|
Over the course of his career, Tom Mansell made 812 plate appearances and pitched 6 innings. Mansell was worth -1.0 Wins Above Replacement (-0.6 as a hitter and -0.4 as a pitcher) and -3.3 Wins Above Average (-2.9 as a hitter and -0.5 as a pitcher).
After adjusting for length of schedule, catchers, and relief pitchers, the -1.0 WAR becomes -1.2 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 -3.3 WAA becomes 0.7 adjWAA.
Then, the adjWAR and adjWAA are combined, but with extra weighting given to adjWAA. This gives Mansell 0.1 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 Mansell has a Hall Rating of 0, leaving him nowhere close to induction to the Hall of Stats.
