|About the stats|
Over the course of his career, Bill Sampen pitched 299 innings and made 32 plate appearances. Sampen was worth 1.6 Wins Above Replacement (1.7 as a pitcher and -0.1 as a hitter) and -0.8 Wins Above Average (-0.6 as a pitcher and -0.1 as a hitter).
After adjusting for length of schedule, catchers, and relief pitchers, the 1.6 WAR becomes 1.9 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 -0.8 WAA becomes 1.0 adjWAA.
Then, the adjWAR and adjWAA are combined, but with extra weighting given to adjWAA. This gives Sampen 3.7 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).
Bill Sampen has a Hall Rating of 3, leaving him nowhere close to induction to the Hall of Stats.
