Over the course of his career,
Christy Mathewson
pitched 4,788 innings
and made 1,889 plate appearances.
Mathewson was worth 97.1 Wins Above Replacement
(90.8 as a pitcher and 6.3 as a hitter)
and 64.8 Wins Above Average
(58.3 as a pitcher and 6.5 as a hitter).
After adjusting for length of schedule, catchers, and relief pitchers, the 97.1 WAR becomes
99.4 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 64.8 WAA becomes 66.0 adjWAA.
Then, the adjWAR and adjWAA are combined, but with extra weighting given to adjWAA.
This gives Mathewson 211.0 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).
Christy Mathewson has a Hall Rating of 208,
making him not only a member of the Hall of Stats—but one of the very best players of all time.
