|About the stats|
Over the course of his career, Marvin Barker made 1,560 plate appearances and pitched 59 innings. Barker was worth -1.1 Wins Above Replacement (-1.6 as a hitter and 0.6 as a pitcher) and -5.9 Wins Above Average (-6.0 as a hitter and 0.1 as a pitcher).
After adjusting for length of schedule, catchers, and relief pitchers, the -1.1 WAR becomes -3.6 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 -5.9 WAA becomes 1.3 adjWAA.
Then, the adjWAR and adjWAA are combined, but with extra weighting given to adjWAA. This gives Barker -1.3 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).
Marvin Barker has a Hall Rating of -1, leaving him nowhere close to induction to the Hall of Stats.
