|About the stats|
Over the course of his career, Bill Monbouquette pitched 1,961 innings and made 701 plate appearances. Monbouquette was worth 21.0 Wins Above Replacement (22.7 as a pitcher and -2.0 as a hitter) and 5.1 Wins Above Average (7.1 as a pitcher and -2.0 as a hitter).
After adjusting for length of schedule, catchers, and relief pitchers, the 21.0 WAR becomes 21.4 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 5.1 WAA becomes 12.3 adjWAA.
Then, the adjWAR and adjWAA are combined, but with extra weighting given to adjWAA. This gives Monbouquette 43.5 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).
Bill Monbouquette has a Hall Rating of 41, leaving him nowhere close to induction to the Hall of Stats.
