Over the course of his career,
Jake Arrieta
pitched 1,612 innings
and made 426 plate appearances.
Arrieta
was worth
22.8 Wins Above Replacement
(21.2 as a pitcher and 1.7 as a hitter)
and 9.0 Wins Above Average
(7.5 as a pitcher and 1.7 as a hitter).
After adjusting for length of schedule, catchers, and relief pitchers, the 22.8 WAR becomes
24.1 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 9.0 WAA becomes 15.0 adjWAA.
Then, the adjWAR and adjWAA are combined, but with extra weighting given to adjWAA.
This gives Arrieta 51.1 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).
Jake Arrieta has a Hall Rating of
48,
leaving him nowhere close to induction to the Hall of Stats when eligible.
