Over the course of his career,
Arthur Irwin
made 4,190 plate appearances
and pitched 4 innings.
Irwin
was worth
15.2 Wins Above Replacement
(15.2 as a hitter and -0.1 as a pitcher)
and 0.5 Wins Above Average
(0.7 as a hitter and -0.1 as a pitcher).
After adjusting for length of schedule, catchers, and relief pitchers, the 15.2 WAR becomes
19.1 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 0.5 WAA becomes 5.8 adjWAA.
Then, the adjWAR and adjWAA are combined, but with extra weighting given to adjWAA.
This gives Irwin 29.5 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).
Arthur Irwin has a Hall Rating of
28,
leaving him nowhere close to induction to the Hall of Stats.
