|About the stats|
Over the course of his career, Frank Robinson made 11,744 plate appearances. Robinson was worth 107.4 Wins Above Replacement and 64.6 Wins Above Average.
After adjusting for length of schedule, catchers, and relief pitchers, the 107.4 WAR becomes 108.2 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 64.6 WAA becomes 65.0 adjWAA.
Then, the adjWAR and adjWAA are combined, but with extra weighting given to adjWAA. This gives Robinson 225.2 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).
Frank Robinson has a Hall Rating of 212, making him not only a member of the Hall of Stats—but one of the very best players of all time.
