|About the stats|
Over the course of his career, Frank Killen pitched 2,511 innings and made 1,148 plate appearances. Killen was worth 34.6 Wins Above Replacement (30.5 as a pitcher and 3.9 as a hitter) and 12.8 Wins Above Average (9.1 as a pitcher and 3.7 as a hitter).
After adjusting for length of schedule, catchers, and relief pitchers, the 34.6 WAR becomes 34.1 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 12.8 WAA becomes 12.2 adjWAA.
Then, the adjWAR and adjWAA are combined, but with extra weighting given to adjWAA. This gives Killen 56.1 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).
Frank Killen has a Hall Rating of 53, leaving him nowhere close to induction to the Hall of Stats.
