|About the stats|
Over the course of his career, Jim O'Rourke made 9,052 plate appearances and pitched 19 innings. O'Rourke was worth 52.3 Wins Above Replacement (52.1 as a hitter and 0.1 as a pitcher) and 21.7 Wins Above Average (21.9 as a hitter and 0.0 as a pitcher).
After adjusting for length of schedule, catchers, and relief pitchers, the 52.3 WAR becomes 72.6 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 21.7 WAA becomes 23.8 adjWAA.
Then, the adjWAR and adjWAA are combined, but with extra weighting given to adjWAA. This gives O'Rourke 115.4 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).
Jim O'Rourke has a Hall Rating of 108, making him a member of the Hall of Stats—but one who sits very close to the borderline.
