Power Finesse Ratio Records and Details
What is Power Finesse Ratio ?
Power finesse ratio (PFR) is a metric that estimates the number of times per inning pitched that a plate apperance ended, either negatively or positivly for the pitcher, because of the pitchers actions. It's calculated by summing walks and strikeouts over a given time period and then divided by innings pitched. Generally, for Power Finesse Ratio, higher is better. (Source)
What is a good Power Finesse Ratio?
What does good Power Finesse Ratio mean? "Good" baseball stats can be very subjective and mean different things to different people. I have attempted to quantify good and bad by taking season and career stats for MLB pitchers with a minimum number of pitched outs. In this case 100 for career and 50 for a season. To find good and bad within this cohort of players I calculated the first and third quartiles, anything between these quartiles I consider average. This makes up the middle 50% of players. In an example where higher is better for a stat, below the first quartile (bottom 25% of players) would be bad and above the 3rd quartile (top 25% of players) would be good. For stats where lower is better, flip around good and bad.
Career, Season, and Season Average Power Finesse Ratio Records
For my hot take on Power Finesse Ratio records most of the same rules apply from the first section. To be considered for my prestigious lists the player must meet a certain threshold of pitched outs. Since this is a Pitching stat to be considered for the career list the player must have over 100 pitched outs, for a season consideration the player must have had 75 pitched outs. Additionally, the player's final game must have been after 1899.
