|About the stats|
Over the course of his career, Mark Mulder pitched 1,314 innings and made 131 plate appearances. Mulder was worth 20.0 Wins Above Replacement (19.6 as a pitcher and 0.4 as a hitter) and 8.0 Wins Above Average (7.6 as a pitcher and 0.4 as a hitter).
After adjusting for length of schedule, catchers, and relief pitchers, the 20.0 WAR becomes 19.9 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 8.0 WAA becomes 12.0 adjWAA.
Then, the adjWAR and adjWAA are combined, but with extra weighting given to adjWAA. This gives Mulder 41.5 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 Mulder has a Hall Rating of 39, leaving him nowhere close to induction to the Hall of Stats.
