Over the course of his career,
Lefty Grove
pitched 3,938 innings
and made 1,578 plate appearances.
Grove
was worth
106.8 Wins Above Replacement
(113.3 as a pitcher and -6.5 as a hitter)
and 66.5 Wins Above Average
(73.1 as a pitcher and -6.5 as a hitter).
After adjusting for length of schedule, catchers, and relief pitchers, the 106.8 WAR becomes
111.5 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 66.5 WAA becomes 78.7 adjWAA.
Then, the adjWAR and adjWAA are combined, but with extra weighting given to adjWAA.
This gives Grove 253.2 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).
Lefty Grove has a Hall Rating of
238,
making him not only a member of the Hall of Stats—but one of the very best players of all time.
