|About the stats|
Over the course of his career, Mark Prior pitched 657 innings and made 234 plate appearances. Prior was worth 16.6 Wins Above Replacement (15.7 as a pitcher and 0.8 as a hitter) and 11.3 Wins Above Average (10.6 as a pitcher and 0.8 as a hitter).
After adjusting for length of schedule, catchers, and relief pitchers, the 16.6 WAR becomes 16.6 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 11.3 WAA becomes 11.8 adjWAA.
Then, the adjWAR and adjWAA are combined, but with extra weighting given to adjWAA. This gives Prior 37.8 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).
Mark Prior has a Hall Rating of 36, leaving him nowhere close to induction to the Hall of Stats.
