|About the stats|
Over the course of his career, Sonny Siebert pitched 2,152 innings and made 725 plate appearances. Siebert was worth 32.4 Wins Above Replacement (29.3 as a pitcher and 2.8 as a hitter) and 14.0 Wins Above Average (11.1 as a pitcher and 2.8 as a hitter).
After adjusting for length of schedule, catchers, and relief pitchers, the 32.4 WAR becomes 33.2 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 14.0 WAA becomes 17.0 adjWAA.
Then, the adjWAR and adjWAA are combined, but with extra weighting given to adjWAA. This gives Siebert 63.8 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).
Sonny Siebert has a Hall Rating of 60, leaving him nowhere close to induction to the Hall of Stats.
