|About the stats|
So far in his career, Koji Uehara has pitched 480 innings and made 3 plate appearances. Uehara has been worth 13.8 Wins Above Replacement (13.66 as a pitcher and 0.0 as a hitter) and 8.2 Wins Above Average (8.2401 as a pitcher and 0.0 as a hitter).
After adjusting for length of schedule, catchers, and relief pitchers, the 13.8 WAR becomes 16.1 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 8.2 WAA becomes 9.9 adjWAA.
Then, the adjWAR and adjWAA are combined, but with extra weighting given to adjWAA. This gives Uehara 33.9 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).
Koji Uehara has a Hall Rating of 32, meaning he would not be in the Hall of Stats if his career ended today.
