So far in his career,
Kenley Jansen
has
pitched 769 innings
and made 10 plate appearances.
Jansen
has been worth
19.8 Wins Above Replacement
(19.5 as a pitcher and 0.2 as a hitter)
and 11.2 Wins Above Average
(11.0 as a pitcher and 0.2 as a hitter).
After adjusting for length of schedule, catchers, and relief pitchers, the 19.8 WAR becomes
24.0 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 11.2 WAA becomes 13.4 adjWAA.
Then, the adjWAR and adjWAA are combined, but with extra weighting given to adjWAA.
This gives Jansen 48.1 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).
Kenley Jansen has a Hall Rating of
45,
meaning he would not be in the Hall of Stats if his career ended today.
