|About the stats|
Over the course of his career, Rogelio Alonso made 708 plate appearances and pitched 106 innings. Alonso was worth -2.0 Wins Above Replacement (-1.3 as a hitter and -0.6 as a pitcher) and -5.0 Wins Above Average (-3.5 as a hitter and -1.5 as a pitcher).
After adjusting for length of schedule, catchers, and relief pitchers, the -2.0 WAR becomes -3.3 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 -5.0 WAA becomes 0.2 adjWAA.
Then, the adjWAR and adjWAA are combined, but with extra weighting given to adjWAA. This gives Alonso -2.9 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).
Rogelio Alonso has a Hall Rating of -3, leaving him nowhere close to induction to the Hall of Stats.
