Power finesse ratio or PFR in baseball is a statistical measure of the performance of a pitcher used in Sabermetrics. It is the sum of strikeouts and walks divided by innings pitched. The alternative to a strikeout or a walk is either a hit or an action by a fielder , so it is an estimate of the number of times that the pitcher, rather than the batter or fielder, determines the outcome of the at-bat.
