|About the stats|
Over the course of his career, Al Pratt pitched 330 innings and made 196 plate appearances. Pratt was worth 1.5 Wins Above Replacement (1.6 as a pitcher and -0.1 as a hitter) and -1.2 Wins Above Average (-1.1 as a pitcher and -0.1 as a hitter).
After adjusting for length of schedule, catchers, and relief pitchers, the 1.5 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 -1.2 WAA becomes 0.0 adjWAA.
Then, the adjWAR and adjWAA are combined, but with extra weighting given to adjWAA. This gives Pratt 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).
Al Pratt has a Hall Rating of 1, leaving him nowhere close to induction to the Hall of Stats.
