|About the stats|
Over the course of his career, Brian Bannister pitched 667 innings and made 33 plate appearances. Bannister was worth 4.9 Wins Above Replacement (4.6 as a pitcher and 0.3 as a hitter) and -1.5 Wins Above Average (-1.8 as a pitcher and 0.3 as a hitter).
After adjusting for length of schedule, catchers, and relief pitchers, the 4.9 WAR becomes 5.0 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 -1.5 WAA becomes 1.4 adjWAA.
Then, the adjWAR and adjWAA are combined, but with extra weighting given to adjWAA. This gives Bannister 7.5 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).
Brian Bannister has a Hall Rating of 7, leaving him nowhere close to induction to the Hall of Stats.
