Hall of Stats

Over the course of his career, Tommy John pitched 4,710 innings and made 1,030 plate appearances. John was worth 62.3 Wins Above Replacement (62.31 as a pitcher and -0.31 as a hitter) and 21.5 Wins Above Average (21.8577 as a pitcher and -0.31 as a hitter).

After adjusting for length of schedule, catchers, and relief pitchers, the 62.3 WAR becomes 63.9 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 21.5 WAA becomes 27.3 adjWAA.

Then, the adjWAR and adjWAA are combined, but with extra weighting given to adjWAA. This gives John 112.5 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).

Tommy John has a Hall Rating of 105, making him a member of the Hall of Stats—but one who sits very close to the borderline.
