Range Factor - RF

What is Range Factor - RF?

A baseball statistic that is calculated by determining the sum of a player's putouts and assists, then multiplying that number by nine,  and finally dividing that number by the number of innings played in a particular defensive position.

Sporting Charts explains Range Factor - RF

Range Factor (RF) is different from fielding percentage in that it attempts to determine a fielding player's true contribution to the defense of a team based on his position. Rather than the statistic being based on the amount of safely field balls, it instead stresses the actions the particular player took that directly resulted in outs. Circumstances can sometimes skew this perception, however, as certain positions can benefit from a strong infield (that turns many double plays) or a team with multiple strikeout pitchers (which could cause a catcher's RF to improve, for example).
