|About the stats|
Over the course of his career, Kevin Jarvis pitched 780 innings and made 229 plate appearances. Jarvis was worth -4.0 Wins Above Replacement (-4.6 as a pitcher and 0.5 as a hitter) and -11.0 Wins Above Average (-11.6 as a pitcher and 0.5 as a hitter).
After adjusting for length of schedule, catchers, and relief pitchers, the -4.0 WAR becomes -4.9 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 -11.0 WAA becomes 0.0 adjWAA.
Then, the adjWAR and adjWAA are combined, but with extra weighting given to adjWAA. This gives Jarvis -4.9 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).
Kevin Jarvis has a Hall Rating of -5, leaving him nowhere close to induction to the Hall of Stats.
