|About the stats|
Over the course of his career, Wiley Piatt pitched 1,390 innings and made 597 plate appearances. Piatt was worth 9.5 Wins Above Replacement (8.3 as a pitcher and 1.2 as a hitter) and -2.6 Wins Above Average (-3.8 as a pitcher and 1.1 as a hitter).
After adjusting for length of schedule, catchers, and relief pitchers, the 9.5 WAR becomes 9.6 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 -2.6 WAA becomes 1.9 adjWAA.
Then, the adjWAR and adjWAA are combined, but with extra weighting given to adjWAA. This gives Piatt 13.0 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).
Wiley Piatt has a Hall Rating of 12, leaving him nowhere close to induction to the Hall of Stats.
