Hall of Stats

Over the course of his career, Roger Bresnahan made 5,361 plate appearances and pitched 50 innings. Bresnahan was worth 42.8 Wins Above Replacement (42.0 as a hitter and 0.8 as a pitcher) and 24.5 Wins Above Average (24.2 as a hitter and 0.3 as a pitcher).

After adjusting for length of schedule, catchers, and relief pitchers, the 42.8 WAR becomes 50.0 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 24.5 WAA becomes 30.8 adjWAA.

Then, the adjWAR and adjWAA are combined, but with extra weighting given to adjWAA. This gives Bresnahan 105.4 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).

Roger Bresnahan has a Hall Rating of 99, making him close to the Hall of Stats borderline—but still on the outside.
