Formula
FPCT = (PO + A) / (PO + A + E)
Where FPCT is Fielding Percentage, PO is Putouts (outs directly recorded), A is Assists (throws or deflections contributing to an out), and E is Errors (misplays on balls that should have been fielded). Total Chances = PO + A + E.
Frequently Asked Questions
What is fielding percentage in baseball?
Fielding percentage (FPCT) is a defensive statistic in baseball that measures how reliably a player or team handles batted or thrown balls. It is calculated by dividing the sum of putouts and assists by total chances (putouts + assists + errors). A perfect fielding percentage is 1.000, meaning the player committed no errors. The league average typically falls around .980 to .985 for position players. While fielding percentage is one of the oldest and most commonly referenced defensive metrics, modern analytics also consider range factor, ultimate zone rating (UZR), and defensive runs saved (DRS) for a more complete picture of defensive ability.
What is a good fielding percentage by position?
Fielding percentage expectations vary significantly by position due to the difficulty and volume of plays. First basemen typically have the highest fielding percentages, often .995 or above, because most of their plays involve catching thrown balls. Outfielders generally range from .980 to .990. Second basemen and shortstops, who handle more difficult ground balls and make longer throws, usually have lower percentages around .970 to .985. Third basemen face hard-hit balls and average around .955 to .975. Catchers handle pitches and throws to bases, typically achieving .990 or higher. Pitchers, who field relatively few balls, can vary widely but usually exceed .950.
What counts as an error in baseball fielding?
An error is charged to a fielder when the official scorer determines that a play should have been made with ordinary effort but was not, resulting in the batter or runner advancing. Common errors include dropped fly balls, fumbled ground balls, wild throws that allow runners to advance, and dropped throws at a base. Not all misplays are errors; if a ball is hit too hard or takes a bad hop that a fielder could not reasonably handle, it may be scored as a hit instead. The distinction between a hit and an error is subjective and determined by the official scorer, which is one criticism of fielding percentage as a defensive metric.
Why is fielding percentage considered a limited defensive metric?
Fielding percentage has notable limitations because it only measures whether a fielder successfully completes plays on balls they reach, but does not account for balls they fail to reach at all. A slower fielder with limited range who only attempts easy plays might have a higher fielding percentage than a faster, more skilled fielder who attempts difficult plays and occasionally commits errors. Modern metrics like Ultimate Zone Rating (UZR), Defensive Runs Saved (DRS), and Outs Above Average (OAA) use batted ball data, positioning, and expected catch probabilities to provide a far more comprehensive evaluation of defensive ability, capturing both range and reliability.
