|About the stats|
Over the course of his career, Mel Parnell pitched 1,752 innings and made 729 plate appearances. Parnell was worth 27.8 Wins Above Replacement (27.4 as a pitcher and 0.3 as a hitter) and 13.9 Wins Above Average (13.4 as a pitcher and 0.3 as a hitter).
After adjusting for length of schedule, catchers, and relief pitchers, the 27.8 WAR becomes 28.5 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 13.9 WAA becomes 17.7 adjWAA.
Then, the adjWAR and adjWAA are combined, but with extra weighting given to adjWAA. This gives Parnell 60.4 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).
Mel Parnell has a Hall Rating of 57, leaving him nowhere close to induction to the Hall of Stats.
