Statistic Description: Range Factor per 9 Inn 9 * (Putouts + Assists) / Innings Played
Minimum of 1000 IP, 3000 PA, 500 games (fielding), 200 stolen base attempts (catchers) or 80 stolen base attempts (baserunners only since 1951) or 100 decisions for career and active leaderboards for rate statistics.
This statistic is computed from play-by-play data which is only complete from 1974 to the present. From 1948-1973, the data is incomplete, though for most seasons only less than 20 games per season total are missing. Please see our page on data coverage for a full view of the data used to create these lists.
