Long-time readers of the VORG know of our affinity for “pi.” We offer up the “Pi Young Award” annually to the pitcher in each league whose ERA comes closest to 3.1415. Now, in honor of the ultimate “Pi Day,” we extend our fondness of pi to FIP.
For those of you not up on the latest sabermetric measures, FIP stands for Fielding Independent Pitching.
As stated on the FanGraphs site:
Fielding Independent Pitching (FIP) measures what a player’s ERA would look like over a given period of time if the pitcher were to have experienced league average results on balls in play and league average timing . . .
FIP is a measurement of a pitcher’s performance that strips out the role of defense, luck, and sequencing, making it a more stable indicator of how a pitcher actually performed over a given period of time than a runs allowed based statistic that would be highly dependent on the quality of defense played behind him . . .
Here is the formula for FIP:
FIP = ((13*HR)+(3*(BB+HBP))-(2*K))/IP + constant
The constant is solely to bring FIP onto an ERA scale and is generally around 3.10.
So the VORG presents the top ten pitchers who compiled a FIP closest to 3.1415927 in a season …
