|About the stats|
Over the course of his career, John Wetteland pitched 765 innings and made 51 plate appearances. Wetteland was worth 19.2 Wins Above Replacement (19.1 as a pitcher and 0.2 as a hitter) and 9.3 Wins Above Average (9.0 as a pitcher and 0.2 as a hitter).
After adjusting for length of schedule, catchers, and relief pitchers, the 19.2 WAR becomes 23.9 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 9.3 WAA becomes 12.0 adjWAA.
Then, the adjWAR and adjWAA are combined, but with extra weighting given to adjWAA. This gives Wetteland 45.5 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).
John Wetteland has a Hall Rating of 43, leaving him nowhere close to induction to the Hall of Stats.
