|About the stats|
Over the course of his career, Bob Shirley pitched 1,432 innings and made 302 plate appearances. Shirley was worth 9.6 Wins Above Replacement (10.1 as a pitcher and -0.3 as a hitter) and -2.8 Wins Above Average (-2.4 as a pitcher and -0.3 as a hitter).
After adjusting for length of schedule, catchers, and relief pitchers, the 9.6 WAR becomes 10.8 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 -2.8 WAA becomes 3.5 adjWAA.
Then, the adjWAR and adjWAA are combined, but with extra weighting given to adjWAA. This gives Shirley 17.1 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 Shirley has a Hall Rating of 16, leaving him nowhere close to induction to the Hall of Stats.
