Over the course of his career,
Kelvin Herrera
pitched 513 innings.
Herrera
was worth
10.2 Wins Above Replacement
and 4.6 Wins Above Average.
After adjusting for length of schedule, catchers, and relief pitchers, the 10.2 WAR becomes
11.9 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 4.6 WAA becomes 7.8 adjWAA.
Then, the adjWAR and adjWAA are combined, but with extra weighting given to adjWAA.
This gives Herrera 25.9 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).
Kelvin Herrera has a Hall Rating of
24,
leaving him nowhere close to induction to the Hall of Stats.
