|About the stats|
Over the course of his career, Mike Tiernan made 6,732 plate appearances and pitched 19 innings. Tiernan was worth 41.6 Wins Above Replacement (42.3 as a hitter and -0.8 as a pitcher) and 18.9 Wins Above Average (19.6 as a hitter and -0.9 as a pitcher).
After adjusting for length of schedule, catchers, and relief pitchers, the 41.6 WAR becomes 45.4 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 18.9 WAA becomes 21.8 adjWAA.
Then, the adjWAR and adjWAA are combined, but with extra weighting given to adjWAA. This gives Tiernan 84.6 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).
Mike Tiernan has a Hall Rating of 79, leaving him short of induction to the Hall of Stats.
