|About the stats|
Over the course of his career, Jim Rooker pitched 1,810 innings and made 668 plate appearances. Rooker was worth 19.7 Wins Above Replacement (17.1 as a pitcher and 2.7 as a hitter) and 4.4 Wins Above Average (1.8 as a pitcher and 2.6 as a hitter).
After adjusting for length of schedule, catchers, and relief pitchers, the 19.7 WAR becomes 20.2 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 4.4 WAA becomes 6.9 adjWAA.
Then, the adjWAR and adjWAA are combined, but with extra weighting given to adjWAA. This gives Rooker 32.6 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).
Jim Rooker has a Hall Rating of 31, leaving him nowhere close to induction to the Hall of Stats.
