|About the stats|
Over the course of his career, Jon Niese pitched 1,189 innings and made 413 plate appearances. Niese was worth 8.5 Wins Above Replacement (6.8 as a pitcher and 1.5 as a hitter) and -1.4 Wins Above Average (-2.8 as a pitcher and 1.5 as a hitter).
After adjusting for length of schedule, catchers, and relief pitchers, the 8.5 WAR becomes 8.5 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 -1.4 WAA becomes 1.9 adjWAA.
Then, the adjWAR and adjWAA are combined, but with extra weighting given to adjWAA. This gives Niese 11.9 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).
Jon Niese has a Hall Rating of 11, leaving him nowhere close to induction to the Hall of Stats.
