|About the stats|
Over the course of his career, Don Robinson pitched 1,958 innings and made 665 plate appearances. Robinson was worth 17.5 Wins Above Replacement (12.9 as a pitcher and 4.5 as a hitter) and 0.9 Wins Above Average (-3.2 as a pitcher and 4.3 as a hitter).
After adjusting for length of schedule, catchers, and relief pitchers, the 17.5 WAR becomes 17.8 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 0.9 WAA becomes 5.3 adjWAA.
Then, the adjWAR and adjWAA are combined, but with extra weighting given to adjWAA. This gives Robinson 27.3 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).
Don Robinson has a Hall Rating of 26, leaving him nowhere close to induction to the Hall of Stats.
