Power finesse ratio
Note: This article was proposed for deletion on Wikipedia.
Power finesse ratio or PFR in baseball is a statistical measure of the performance of a pitcher. It is the sum of strikeouts and walks divided by innings pitched.
Alternative to a strikeout or a walk include a hit or an action by a fielder (that is, the batter "puts the ball in play"), so it is an estimate of the number of times that the pitcher, rather than the batter or fielder(s), determines the outcome of the at-bat.
