|About the stats|
Over the course of his career, Mike Sullivan pitched 1,111 innings and made 511 plate appearances. Sullivan was worth -1.7 Wins Above Replacement (0.5 as a pitcher and -2.3 as a hitter) and -11.3 Wins Above Average (-9.0 as a pitcher and -2.3 as a hitter).
After adjusting for length of schedule, catchers, and relief pitchers, the -1.7 WAR becomes -2.0 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 -11.3 WAA becomes 0.2 adjWAA.
Then, the adjWAR and adjWAA are combined, but with extra weighting given to adjWAA. This gives Sullivan -1.6 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).
Mike Sullivan has a Hall Rating of -2, leaving him nowhere close to induction to the Hall of Stats.
