|About the stats|
Over the course of his career, Billy Serad pitched 787 innings and made 351 plate appearances. Serad was worth -7.4 Wins Above Replacement (-5.5 as a pitcher and -2.0 as a hitter) and -13.0 Wins Above Average (-11.0 as a pitcher and -2.0 as a hitter).
After adjusting for length of schedule, catchers, and relief pitchers, the -7.4 WAR becomes -6.8 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 -13.0 WAA becomes 0.0 adjWAA.
Then, the adjWAR and adjWAA are combined, but with extra weighting given to adjWAA. This gives Serad -6.8 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).
Billy Serad has a Hall Rating of -6, leaving him nowhere close to induction to the Hall of Stats.
