|About the stats|
Over the course of his career, Bruce Chen pitched 1,532 innings and made 147 plate appearances. Chen was worth 10.8 Wins Above Replacement (10.8 as a pitcher and -0.3 as a hitter) and -3.9 Wins Above Average (-3.6 as a pitcher and -0.3 as a hitter).
After adjusting for length of schedule, catchers, and relief pitchers, the 10.8 WAR becomes 10.7 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 -3.9 WAA becomes 7.0 adjWAA.
Then, the adjWAR and adjWAA are combined, but with extra weighting given to adjWAA. This gives Chen 23.3 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).
Bruce Chen has a Hall Rating of 22, leaving him nowhere close to induction to the Hall of Stats.
