|About the stats|
Over the course of his career, Melvin Powell made 504 plate appearances and pitched 349 innings. Powell was worth 2.4 Wins Above Replacement (-0.6 as a hitter and 2.9 as a pitcher) and -1.6 Wins Above Average (-1.7 as a hitter and 0.2 as a pitcher).
After adjusting for length of schedule, catchers, and relief pitchers, the 2.4 WAR becomes 2.5 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 2.7 adjWAA.
Then, the adjWAR and adjWAA are combined, but with extra weighting given to adjWAA. This gives Powell 7.4 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).
Melvin Powell has a Hall Rating of 7, leaving him nowhere close to induction to the Hall of Stats.
