|About the stats|
Over the course of his career, John Smoltz pitched 3,473 innings and made 1,167 plate appearances. Smoltz was worth 68.9 Wins Above Replacement (66.4 as a pitcher and 2.6 as a hitter) and 40.4 Wins Above Average (37.9 as a pitcher and 2.5 as a hitter).
After adjusting for length of schedule, catchers, and relief pitchers, the 68.9 WAR becomes 71.4 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 40.4 WAA becomes 40.8 adjWAA.
Then, the adjWAR and adjWAA are combined, but with extra weighting given to adjWAA. This gives Smoltz 144.8 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).
John Smoltz has a Hall Rating of 136, making him a member of the Hall of Stats.
