|About the stats|
Over the course of his career, James Roseman made 2,956 plate appearances and pitched 16 innings. Roseman was worth 3.7 Wins Above Replacement (4.5 as a hitter and -0.8 as a pitcher) and -3.7 Wins Above Average (-2.8 as a hitter and -0.9 as a pitcher).
After adjusting for length of schedule, catchers, and relief pitchers, the 3.7 WAR becomes 4.8 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 -3.7 WAA becomes 4.0 adjWAA.
Then, the adjWAR and adjWAA are combined, but with extra weighting given to adjWAA. This gives Roseman 12.0 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).
James Roseman has a Hall Rating of 11, leaving him nowhere close to induction to the Hall of Stats.
