Over the course of his career,
Robin Roberts
pitched 4,688 innings
and made 1,784 plate appearances.
Roberts
was worth
86.1 Wins Above Replacement
(83.0 as a pitcher and 3.1 as a hitter)
and 41.6 Wins Above Average
(38.5 as a pitcher and 3.1 as a hitter).
After adjusting for length of schedule, catchers, and relief pitchers, the 86.1 WAR becomes
87.3 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 41.6 WAA becomes 43.7 adjWAA.
Then, the adjWAR and adjWAA are combined, but with extra weighting given to adjWAA.
This gives Roberts 166.1 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).
Robin Roberts has a Hall Rating of
154,
making him a member of the Hall of Stats.
