|About the stats|
Over the course of his career, Fernando Valenzuela pitched 2,930 innings and made 1,044 plate appearances. Valenzuela was worth 41.6 Wins Above Replacement (37.4 as a pitcher and 4.1 as a hitter) and 16.0 Wins Above Average (12.1 as a pitcher and 3.9 as a hitter).
After adjusting for length of schedule, catchers, and relief pitchers, the 41.6 WAR becomes 44.8 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 16.0 WAA becomes 18.9 adjWAA.
Then, the adjWAR and adjWAA are combined, but with extra weighting given to adjWAA. This gives Valenzuela 78.8 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).
Fernando Valenzuela has a Hall Rating of 74, leaving him short of induction to the Hall of Stats.
