|About the stats|
So far in his career, Stephen Strasburg has pitched 1,470 innings and made 521 plate appearances. Strasburg has been worth 32.4 Wins Above Replacement (30.9 as a pitcher and 1.4 as a hitter) and 20.3 Wins Above Average (19.0 as a pitcher and 1.4 as a hitter).
After adjusting for length of schedule, catchers, and relief pitchers, the 32.4 WAR becomes 31.9 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 20.3 WAA becomes 19.8 adjWAA.
Then, the adjWAR and adjWAA are combined, but with extra weighting given to adjWAA. This gives Strasburg 67.5 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).
Stephen Strasburg has a Hall Rating of 63, meaning he would not be in the Hall of Stats if his career ended today.
