|About the stats|
So far in his career, David Robertson has pitched 739 innings and made 1 plate appearances. Robertson has been worth 18.5 Wins Above Replacement (18.3 as a pitcher and 0.0 as a hitter) and 9.4 Wins Above Average (9.5 as a pitcher and 0.0 as a hitter).
After adjusting for length of schedule, catchers, and relief pitchers, the 18.5 WAR becomes 21.8 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 9.4 WAA becomes 11.9 adjWAA.
Then, the adjWAR and adjWAA are combined, but with extra weighting given to adjWAA. This gives Robertson 43.2 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).
David Robertson has a Hall Rating of 41, meaning he would not be in the Hall of Stats if his career ended today.
