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.
RP (Runs Produced) = R+RBI-HR. 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 1876-2010. 2011 data is not included here, though some players may be active. See first comment for team/franchise abbreviations.
