|About the stats|
Over the course of his career, Jack Armstrong pitched 786 innings and made 215 plate appearances. Armstrong was worth 1.1 Wins Above Replacement (2.4 as a pitcher and -1.2 as a hitter) and -5.4 Wins Above Average (-4.3 as a pitcher and -1.2 as a hitter).
After adjusting for length of schedule, catchers, and relief pitchers, the 1.1 WAR becomes 1.3 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 -5.4 WAA becomes 1.7 adjWAA.
Then, the adjWAR and adjWAA are combined, but with extra weighting given to adjWAA. This gives Armstrong 4.4 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).
Jack Armstrong has a Hall Rating of 4, leaving him nowhere close to induction to the Hall of Stats.
