|About the stats|
Over the course of his career, Hugh Mulcahy pitched 1,161 innings and made 426 plate appearances. Mulcahy was worth 3.8 Wins Above Replacement (4.3 as a pitcher and -0.6 as a hitter) and -5.7 Wins Above Average (-5.1 as a pitcher and -0.6 as a hitter).
After adjusting for length of schedule, catchers, and relief pitchers, the 3.8 WAR becomes 3.9 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 -5.7 WAA becomes 0.6 adjWAA.
Then, the adjWAR and adjWAA are combined, but with extra weighting given to adjWAA. This gives Mulcahy 5.0 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).
Hugh Mulcahy has a Hall Rating of 5, leaving him nowhere close to induction to the Hall of Stats.
