Over the course of his career,
Dave Roberts
pitched 2,099 innings
and made 590 plate appearances.
Roberts
was worth
23.5 Wins Above Replacement
(22.2 as a pitcher and 1.4 as a hitter)
and 5.5 Wins Above Average
(4.2 as a pitcher and 1.3 as a hitter).
After adjusting for length of schedule, catchers, and relief pitchers, the 23.5 WAR becomes
24.0 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 5.5 WAA becomes 13.2 adjWAA.
Then, the adjWAR and adjWAA are combined, but with extra weighting given to adjWAA.
This gives Roberts 47.8 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).
Dave Roberts has a Hall Rating of
45,
leaving him nowhere close to induction to the Hall of Stats.
