Over the course of his career,
Jason Grilli
pitched 684 innings
and made 18 plate appearances.
Grilli
was worth
4.7 Wins Above Replacement
(4.5 as a pitcher and 0.1 as a hitter)
and -0.9 Wins Above Average
(-0.9 as a pitcher and 0.1 as a hitter).
After adjusting for length of schedule, catchers, and relief pitchers, the 4.7 WAR becomes
5.8 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 3.8 adjWAA.
Then, the adjWAR and adjWAA are combined, but with extra weighting given to adjWAA.
This gives Grilli 12.6 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).
Jason Grilli has a Hall Rating of
12,
leaving him nowhere close to induction to the Hall of Stats when eligible.
