|About the stats|
Over the course of his career, Tim Keefe pitched 5,049 innings and made 2,262 plate appearances. Keefe was worth 87.0 Wins Above Replacement (89.1 as a pitcher and -2.3 as a hitter) and 48.8 Wins Above Average (51.3 as a pitcher and -2.5 as a hitter).
After adjusting for length of schedule, catchers, and relief pitchers, the 87.0 WAR becomes 69.5 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 48.8 WAA becomes 44.1 adjWAA.
Then, the adjWAR and adjWAA are combined, but with extra weighting given to adjWAA. This gives Keefe 148.9 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).
Tim Keefe has a Hall Rating of 140, making him a member of the Hall of Stats.
