|About the stats|
Over the course of his career, Hideki Irabu pitched 514 innings and made 34 plate appearances. Irabu was worth 3.4 Wins Above Replacement (3.4 as a pitcher and 0.0 as a hitter) and -1.1 Wins Above Average (-1.3 as a pitcher and 0.0 as a hitter).
After adjusting for length of schedule, catchers, and relief pitchers, the 3.4 WAR becomes 3.6 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 -1.1 WAA becomes 1.4 adjWAA.
Then, the adjWAR and adjWAA are combined, but with extra weighting given to adjWAA. This gives Irabu 6.1 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).
Hideki Irabu has a Hall Rating of 6, leaving him nowhere close to induction to the Hall of Stats.
