|About the stats|
Over the course of his career, Wei-Yin Chen pitched 1,064 innings and made 111 plate appearances. Chen was worth 8.3 Wins Above Replacement (9.0 as a pitcher and -0.7 as a hitter) and -1.3 Wins Above Average (-0.7 as a pitcher and -0.8 as a hitter).
After adjusting for length of schedule, catchers, and relief pitchers, the 8.3 WAR becomes 8.1 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 -1.3 WAA becomes 3.2 adjWAA.
Then, the adjWAR and adjWAA are combined, but with extra weighting given to adjWAA. This gives Chen 13.9 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).
Wei-Yin Chen has a Hall Rating of 13, leaving him nowhere close to induction to the Hall of Stats when eligible.
