Over the course of his career,
Roy Halladay
pitched 2,749 innings
and made 305 plate appearances.
Halladay
was worth
64.2 Wins Above Replacement
(65.4 as a pitcher and -1.1 as a hitter)
and 39.2 Wins Above Average
(40.4 as a pitcher and -1.1 as a hitter).
After adjusting for length of schedule, catchers, and relief pitchers, the 64.2 WAR becomes
64.5 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 39.2 WAA becomes 46.2 adjWAA.
Then, the adjWAR and adjWAA are combined, but with extra weighting given to adjWAA.
This gives Halladay 147.7 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).
Roy Halladay has a Hall Rating of
139,
making him a member of the Hall of Stats.
