|About the stats|
Over the course of his career, Cinders O'Brien pitched 1,080 innings and made 502 plate appearances. O'Brien was worth 4.1 Wins Above Replacement (4.4 as a pitcher and -0.3 as a hitter) and -2.7 Wins Above Average (-2.4 as a pitcher and -0.4 as a hitter).
After adjusting for length of schedule, catchers, and relief pitchers, the 4.1 WAR becomes 3.0 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 -2.7 WAA becomes 1.2 adjWAA.
Then, the adjWAR and adjWAA are combined, but with extra weighting given to adjWAA. This gives O'Brien 5.2 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).
Cinders O'Brien has a Hall Rating of 5, leaving him nowhere close to induction to the Hall of Stats.
