|About the stats|
So far in his career, Yoshihisa Hirano has pitched 131 innings and made 1 plate appearances. Hirano has been worth 0.4 Wins Above Replacement (0.4 as a pitcher and 0.0 as a hitter) and -0.5 Wins Above Average (-0.5 as a pitcher and 0.0 as a hitter).
After adjusting for length of schedule, catchers, and relief pitchers, the 0.4 WAR becomes -0.1 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 -0.5 WAA becomes 0.6 adjWAA.
Then, the adjWAR and adjWAA are combined, but with extra weighting given to adjWAA. This gives Hirano 1.0 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).
Yoshihisa Hirano has a Hall Rating of 1, meaning he would not be in the Hall of Stats if his career ended today.
