So far in his career,
Jake Arrieta
has
pitched 1,333 innings
and made 346 plate appearances.
Arrieta
has been worth
24.6 Wins Above Replacement
(23.07 as a pitcher and 1.4 as a hitter)
and 13.1 Wins Above Average
(11.7219 as a pitcher and 1.4 as a hitter).
After adjusting for length of schedule, catchers, and relief pitchers, the 24.6 WAR becomes
24.6 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 13.1 WAA becomes 15.1 adjWAA.
Then, the adjWAR and adjWAA are combined, but with extra weighting given to adjWAA.
This gives Arrieta 51.8 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
49,
meaning he would not be in the Hall of Stats if his career ended today.
