|About the stats|
So far in his career, Derek Holland has pitched 1,466 innings and made 91 plate appearances. Holland has been worth 8.6 Wins Above Replacement (9.1 as a pitcher and -0.4 as a hitter) and -4.7 Wins Above Average (-4.2 as a pitcher and -0.4 as a hitter).
After adjusting for length of schedule, catchers, and relief pitchers, the 8.6 WAR becomes 6.7 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 -4.7 WAA becomes 4.6 adjWAA.
Then, the adjWAR and adjWAA are combined, but with extra weighting given to adjWAA. This gives Holland 15.0 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).
Derek Holland has a Hall Rating of 14, meaning he would not be in the Hall of Stats if his career ended today.
