|About the stats|
So far in his career, Oliver Perez has pitched 1,465 innings and made 399 plate appearances. Perez has been worth 10.8 Wins Above Replacement (10.2 as a pitcher and 0.5 as a hitter) and -0.7 Wins Above Average (-1.2 as a pitcher and 0.5 as a hitter).
After adjusting for length of schedule, catchers, and relief pitchers, the 10.8 WAR becomes 12.1 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 -0.7 WAA becomes 9.0 adjWAA.
Then, the adjWAR and adjWAA are combined, but with extra weighting given to adjWAA. This gives Perez 28.3 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).
Oliver Perez has a Hall Rating of 27, meaning he would not be in the Hall of Stats if his career ended today.
