|About the stats|
Over the course of his career, Roberto Hernandez pitched 1,358 innings and made 85 plate appearances. Hernandez was worth 4.6 Wins Above Replacement (5.4 as a pitcher and -0.7 as a hitter) and -8.0 Wins Above Average (-7.3 as a pitcher and -0.7 as a hitter).
After adjusting for length of schedule, catchers, and relief pitchers, the 4.6 WAR becomes 4.7 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 -8.0 WAA becomes 5.3 adjWAA.
Then, the adjWAR and adjWAA are combined, but with extra weighting given to adjWAA. This gives Hernandez 14.2 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).
Roberto Hernandez has a Hall Rating of 13, leaving him nowhere close to induction to the Hall of Stats.
