|About the stats|
Over the course of his career, Dan Warthen pitched 307 innings and made 97 plate appearances. Warthen was worth 0.6 Wins Above Replacement (1.4 as a pitcher and -0.8 as a hitter) and -2.2 Wins Above Average (-1.4 as a pitcher and -0.8 as a hitter).
After adjusting for length of schedule, catchers, and relief pitchers, the 0.6 WAR becomes 0.8 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 -2.2 WAA becomes 2.2 adjWAA.
Then, the adjWAR and adjWAA are combined, but with extra weighting given to adjWAA. This gives Warthen 4.8 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).
Dan Warthen has a Hall Rating of 4, leaving him nowhere close to induction to the Hall of Stats.
