|About the stats|
Over the course of his career, Frank Welch made 2,682 plate appearances. Welch was worth 4.4 Wins Above Replacement and -5.9 Wins Above Average.
After adjusting for length of schedule, catchers, and relief pitchers, the 4.4 WAR becomes 4.5 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 -5.9 WAA becomes 0.6 adjWAA.
Then, the adjWAR and adjWAA are combined, but with extra weighting given to adjWAA. This gives Welch 5.6 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).
Frank Welch has a Hall Rating of 5, leaving him nowhere close to induction to the Hall of Stats.
