RP (Runs Produced) = R+RBI-HR. For each player's season, RPAA equals RP - AB*LgRP/LgAB. In high run-scoring environments, each run produced is "worth" less, and vice versa. Season RPAA totals are summed to find career RPAA totals. Player's actual career RP are in parentheses. Each player is listed with the team on which he played the most games and the first and last (or most recently completed) seasons of his career. Data is from 1876-2015. See first comment for team/franchise abbreviations.
