|About the stats|
Over the course of his career, Bob Purkey pitched 2,114 innings and made 748 plate appearances. Purkey was worth 22.9 Wins Above Replacement (24.9 as a pitcher and -2.0 as a hitter) and 2.7 Wins Above Average (4.8 as a pitcher and -2.0 as a hitter).
After adjusting for length of schedule, catchers, and relief pitchers, the 22.9 WAR becomes 23.4 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 2.7 WAA becomes 10.2 adjWAA.
Then, the adjWAR and adjWAA are combined, but with extra weighting given to adjWAA. This gives Purkey 41.8 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).
Bob Purkey has a Hall Rating of 39, leaving him nowhere close to induction to the Hall of Stats.
