Over the course of his career,
Randy Johnson
pitched 4,135 innings
and made 691 plate appearances.
Johnson
was worth
101.2 Wins Above Replacement
(103.5 as a pitcher and -2.5 as a hitter)
and 64.7 Wins Above Average
(67.4 as a pitcher and -2.5 as a hitter).
After adjusting for length of schedule, catchers, and relief pitchers, the 101.2 WAR becomes
104.4 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 64.7 WAA becomes 70.4 adjWAA.
Then, the adjWAR and adjWAA are combined, but with extra weighting given to adjWAA.
This gives Johnson 231.1 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).
Randy Johnson has a Hall Rating of
217,
making him not only a member of the Hall of Stats—but one of the very best players of all time.
