Over the course of his career,
Bobby Mathews
pitched 4,956 innings
and made 2,559 plate appearances.
Mathews was worth 58.8 Wins Above Replacement
(65.6 as a pitcher and -6.8 as a hitter)
and 21.6 Wins Above Average
(28.6 as a pitcher and -7.1 as a hitter).
After adjusting for length of schedule, catchers, and relief pitchers, the 58.8 WAR becomes
41.8 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 21.6 WAA becomes 29.3 adjWAA.
Then, the adjWAR and adjWAA are combined, but with extra weighting given to adjWAA.
This gives Mathews 91.3 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).
Bobby Mathews has a Hall Rating of 90,
making him close to the Hall of Stats borderline—but still on the outside.
