|About the stats|
Over the course of his career, Jim Fregosi made 7,404 plate appearances. Fregosi was worth 48.9 Wins Above Replacement and 24.4 Wins Above Average.
After adjusting for length of schedule, catchers, and relief pitchers, the 48.9 WAR becomes 48.9 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 24.4 WAA becomes 28.0 adjWAA.
Then, the adjWAR and adjWAA are combined, but with extra weighting given to adjWAA. This gives Fregosi 99.3 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).
Jim Fregosi has a Hall Rating of 93, making him close to the Hall of Stats borderline—but still on the outside.
