|About the stats|
Over the course of his career, Mark Petkovsek pitched 710 innings and made 102 plate appearances. Petkovsek was worth 0.8 Wins Above Replacement (0.6 as a pitcher and 0.1 as a hitter) and -5.1 Wins Above Average (-5.2 as a pitcher and 0.1 as a hitter).
After adjusting for length of schedule, catchers, and relief pitchers, the 0.8 WAR becomes 0.8 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 -5.1 WAA becomes 1.5 adjWAA.
Then, the adjWAR and adjWAA are combined, but with extra weighting given to adjWAA. This gives Petkovsek 3.5 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 Petkovsek has a Hall Rating of 3, leaving him nowhere close to induction to the Hall of Stats.
