|About the stats|
Over the course of his career, Brad Havens pitched 590 innings and made 3 plate appearances. Havens was worth 1.2 Wins Above Replacement (1.2 as a pitcher and 0.0 as a hitter) and -3.7 Wins Above Average (-3.6 as a pitcher and 0.0 as a hitter).
After adjusting for length of schedule, catchers, and relief pitchers, the 1.2 WAR becomes 2.1 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 -3.7 WAA becomes 1.7 adjWAA.
Then, the adjWAR and adjWAA are combined, but with extra weighting given to adjWAA. This gives Havens 5.2 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).
Brad Havens has a Hall Rating of 5, leaving him nowhere close to induction to the Hall of Stats.
