So far in his career,
Jeff Mathis
has
made 2,938 plate appearances
and pitched 5 innings.
Mathis
has been worth
-0.6 Wins Above Replacement
(-0.4 as a hitter and -0.2 as a pitcher)
and -10.7 Wins Above Average
(-10.4 as a hitter and -0.3 as a pitcher).
After adjusting for length of schedule, catchers, and relief pitchers, the -0.6 WAR becomes
-0.7 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 -10.7 WAA becomes 0.0 adjWAA.
Then, the adjWAR and adjWAA are combined, but with extra weighting given to adjWAA.
This gives Mathis -0.7 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).
Jeff Mathis has a Hall Rating of
-1,
meaning he would not be in the Hall of Stats if his career ended today.
