|About the stats|
Over the course of his career, John O'Donoghue pitched 751 innings and made 228 plate appearances. O'Donoghue was worth 4.2 Wins Above Replacement (3.7 as a pitcher and 0.3 as a hitter) and -1.7 Wins Above Average (-1.9 as a pitcher and 0.3 as a hitter).
After adjusting for length of schedule, catchers, and relief pitchers, the 4.2 WAR becomes 4.4 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 -1.7 WAA becomes 2.0 adjWAA.
Then, the adjWAR and adjWAA are combined, but with extra weighting given to adjWAA. This gives O'Donoghue 8.0 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).
John O'Donoghue has a Hall Rating of 7, leaving him nowhere close to induction to the Hall of Stats.
