|About the stats|
Over the course of his career, James McDonald pitched 512 innings and made 171 plate appearances. McDonald was worth 2.5 Wins Above Replacement (2.6 as a pitcher and -0.2 as a hitter) and -1.4 Wins Above Average (-1.3 as a pitcher and -0.2 as a hitter).
After adjusting for length of schedule, catchers, and relief pitchers, the 2.5 WAR becomes 2.6 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 -1.4 WAA becomes 1.1 adjWAA.
Then, the adjWAR and adjWAA are combined, but with extra weighting given to adjWAA. This gives McDonald 4.6 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).
James McDonald has a Hall Rating of 4, leaving him nowhere close to induction to the Hall of Stats.
