|About the stats|
Over the course of his career, Walt Masterson pitched 1,649 innings and made 555 plate appearances. Masterson was worth 9.5 Wins Above Replacement (10.9 as a pitcher and -1.5 as a hitter) and -3.1 Wins Above Average (-1.5 as a pitcher and -1.5 as a hitter).
After adjusting for length of schedule, catchers, and relief pitchers, the 9.5 WAR becomes 9.5 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 -3.1 WAA becomes 8.4 adjWAA.
Then, the adjWAR and adjWAA are combined, but with extra weighting given to adjWAA. This gives Masterson 24.6 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).
Walt Masterson has a Hall Rating of 23, leaving him nowhere close to induction to the Hall of Stats.
