|About the stats|
Over the course of his career, Roberto Clemente made 10,212 plate appearances. Clemente was worth 95.0 Wins Above Replacement and 57.2 Wins Above Average.
After adjusting for length of schedule, catchers, and relief pitchers, the 95.0 WAR becomes 95.5 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 57.2 WAA becomes 59.9 adjWAA.
Then, the adjWAR and adjWAA are combined, but with extra weighting given to adjWAA. This gives Clemente 203.3 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 Clemente has a Hall Rating of 191, making him not only a member of the Hall of Stats—but one of the very best players of all time.
