|About the stats|
Over the course of his career, Juan Rivera made 3,787 plate appearances. Rivera was worth 9.4 Wins Above Replacement and -3.7 Wins Above Average.
After adjusting for length of schedule, catchers, and relief pitchers, the 9.4 WAR becomes 9.4 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 -3.7 WAA becomes 4.2 adjWAA.
Then, the adjWAR and adjWAA are combined, but with extra weighting given to adjWAA. This gives Rivera 17.0 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).
Juan Rivera has a Hall Rating of 16, leaving him nowhere close to induction to the Hall of Stats.
