|About the stats|
Over the course of his career, Tony Mullane pitched 4,531 innings and made 2,971 plate appearances. Mullane was worth 66.4 Wins Above Replacement (61.0 as a pitcher and 5.6 as a hitter) and 37.2 Wins Above Average (34.0 as a pitcher and 3.5 as a hitter).
After adjusting for length of schedule, catchers, and relief pitchers, the 66.4 WAR becomes 57.4 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 37.2 WAA becomes 33.9 adjWAA.
Then, the adjWAR and adjWAA are combined, but with extra weighting given to adjWAA. This gives Mullane 118.4 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).
Tony Mullane has a Hall Rating of 111, making him a member of the Hall of Stats.
