Due to the different opportunities presented to Black and Latino players before integration, the Hall Rating of these players does not accurately reflect their Hall of Fame cases. When possible, the Hall of Stats uses Eric Chalek’s Negro League MLEs to present an alternate Hall Rating for prominent early Black and Latino stars. Biz Mackey has a 107 Hall Rating using these MLEs. The rest of the stats on this page come from real game data, not MLEs.
|About the stats|
Over the course of his career, Biz Mackey made 3,474 plate appearances and pitched 20 innings. Mackey was worth 25.8 Wins Above Replacement (26.2 as a hitter and -0.6 as a pitcher) and 14.3 Wins Above Average (15.2 as a hitter and -0.7 as a pitcher).
After adjusting for length of schedule, catchers, and relief pitchers, the 25.8 WAR becomes 48.3 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 14.3 WAA becomes 18.0 adjWAA.
Then, the adjWAR and adjWAA are combined, but with extra weighting given to adjWAA. This gives Mackey 80.7 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).
Biz Mackey has a Hall Rating of 76, leaving him short of induction to the Hall of Stats.
