|About the stats|
Over the course of his career, David Ortiz made 10,091 plate appearances. Ortiz was worth 55.4 Wins Above Replacement and 20.5 Wins Above Average.
After adjusting for length of schedule, catchers, and relief pitchers, the 55.4 WAR becomes 55.4 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 20.5 WAA becomes 25.3 adjWAA.
Then, the adjWAR and adjWAA are combined, but with extra weighting given to adjWAA. This gives Ortiz 100.9 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).
David Ortiz has a Hall Rating of 95, making him close to the Hall of Stats borderline—but still on the outside.
