|About the stats|
So far in his career, Fernando Tatis Jr. has made 372 plate appearances. Tatis Jr. has been worth 4.2 Wins Above Replacement and 3.1 Wins Above Average.
After adjusting for length of schedule, catchers, and relief pitchers, the 4.2 WAR becomes 4.2 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 3.1 WAA becomes 3.1 adjWAA.
Then, the adjWAR and adjWAA are combined, but with extra weighting given to adjWAA. This gives Tatis Jr. 9.8 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).
Fernando Tatis Jr. has a Hall Rating of 9, meaning he would not be in the Hall of Stats if his career ended today.
