|About the stats|
Over the course of his career, Mark Gardner pitched 1,764 innings and made 589 plate appearances. Gardner was worth 4.7 Wins Above Replacement (6.2 as a pitcher and -1.4 as a hitter) and -9.4 Wins Above Average (-7.8 as a pitcher and -1.5 as a hitter).
After adjusting for length of schedule, catchers, and relief pitchers, the 4.7 WAR becomes 4.9 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 -9.4 WAA becomes 1.3 adjWAA.
Then, the adjWAR and adjWAA are combined, but with extra weighting given to adjWAA. This gives Gardner 7.2 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 Gardner has a Hall Rating of 7, leaving him nowhere close to induction to the Hall of Stats.
