Over the course of his career,
Billy O'Brien
made 1,491 plate appearances
and pitched 10 innings.
O'Brien
was worth
4.0 Wins Above Replacement
(4.1 as a hitter and -0.1 as a pitcher)
and -0.9 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 4.0 WAR becomes
7.8 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 -0.9 WAA becomes 1.3 adjWAA.
Then, the adjWAR and adjWAA are combined, but with extra weighting given to adjWAA.
This gives O'Brien 10.1 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).
Billy O'Brien has a Hall Rating of
10,
leaving him nowhere close to induction to the Hall of Stats.
