So far in his career,
Andy Pettitte
has
pitched 3,130 innings
and made 235 plate appearances.
Pettitte was worth 54.2 Wins Above Replacement
(54.5 as a pitcher and -0.3 as a hitter)
and 29.2 Wins Above Average
(29.5 as a pitcher and -0.3 as a hitter).
After adjusting for length of schedule, catchers, and relief pitchers, the 54.2 WAR becomes
54.7 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 29.2 WAA becomes 29.8 adjWAA.
Then, the adjWAR and adjWAA are combined, but with extra weighting given to adjWAA.
This gives Pettitte 105.1 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).
Andy Pettitte has a Hall Rating of 104,
meaning he would be in the Hall of Stats if his career ended today—but very close to the borderline.
