Range Factor (commonly abbreviated RF) is a baseball statistic developed by Bill James. It is calculated by dividing putouts and assists by number of innings or games played at a given defense position. [1] The statistic is premised on the notion that the total number of outs that a player participates in is more relevant in evaluating his defensive play than the percentage of cleanly handled chances as calculated by the conventional statistic fielding percentage.

However, some positions (especially first baseman) may have substantially more putouts because of a superior infield around them, that commits fewer errors and turns many double plays, allowing them to receive credit for more putouts.
