What is Baseball Fielding Percentage?

Fielding percentage or baseball fielding average is a measure of a defender's percentage of batting or handling a thrown ball correctly. It is calculated by dividing the total probability of putouts and assists (putout + assist + error). The first known use of fielding percentage was in 1972.

To qualify for a league lead in fielding percentage, an fielder or outfielder must appear at a specific position in at least two-thirds of his team's games (outfield games are not separated by position). A catcher must appear in at least half of his team's games. A pitcher must pitch at least one innings for each of his team's scheduled games (however, a pitcher with fewer innings may be eligible if they have higher chances and average). To qualify for the major league career records for the fielding average, a player must be present in 1000 games at this position. The pitcher must have at least 1500 innings. The MLB record of team fielding percentage is currently held by the 2007 Colorado Rocks with a .98925 fielding percentage.
