|About the stats|
Over the course of his career, Walt Terrell pitched 1,986 innings and made 205 plate appearances. Terrell was worth 10.7 Wins Above Replacement (10.9 as a pitcher and -0.2 as a hitter) and -6.7 Wins Above Average (-6.5 as a pitcher and -0.2 as a hitter).
After adjusting for length of schedule, catchers, and relief pitchers, the 10.7 WAR becomes 10.6 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 -6.7 WAA becomes 1.9 adjWAA.
Then, the adjWAR and adjWAA are combined, but with extra weighting given to adjWAA. This gives Terrell 14.0 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).
Walt Terrell has a Hall Rating of 13, leaving him nowhere close to induction to the Hall of Stats.
