|About the stats|
Over the course of his career, Dennis Martinez pitched 3,999 innings and made 604 plate appearances. Martinez was worth 48.6 Wins Above Replacement (49.3 as a pitcher and -0.6 as a hitter) and 14.4 Wins Above Average (14.7 as a pitcher and -0.6 as a hitter).
After adjusting for length of schedule, catchers, and relief pitchers, the 48.6 WAR becomes 51.9 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 14.4 WAA becomes 26.4 adjWAA.
Then, the adjWAR and adjWAA are combined, but with extra weighting given to adjWAA. This gives Martinez 99.4 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).
Dennis Martinez has a Hall Rating of 93, making him close to the Hall of Stats borderline—but still on the outside.
