Over the course of his career,
Mike Mattimore
made 497 plate appearances
and pitched 490 innings.
Mattimore
was worth
-3.1 Wins Above Replacement
(-0.7 as a hitter and -2.5 as a pitcher)
and -6.4 Wins Above Average
(-1.3 as a hitter and -5.1 as a pitcher).
After adjusting for length of schedule, catchers, and relief pitchers, the -3.1 WAR becomes
-3.1 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 -6.4 WAA becomes 1.1 adjWAA.
Then, the adjWAR and adjWAA are combined, but with extra weighting given to adjWAA.
This gives Mattimore -1.1 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).
Mike Mattimore has a Hall Rating of
-1,
leaving him nowhere close to induction to the Hall of Stats.
