In baseball statistics, fielding percentage, also known as fielding average, is a measure that reflects the percentage of times a defensive player properly handles a batted or thrown ball. It is calculated by the sum of putouts and assists divided by the number of total chances (putouts + assists + errors).〔Rule 10.21(d). (【引用サイトリンク】publisher=Major League Baseball (MLB.com) )〕 While a high fielding percentage is regarded as a sign of defensive skill, it is also possible for a player of lesser defensive skill to have a high fielding percentage, as it does not reflect or take into account a player's defensive range; a player that cannot get to a ball surrenders a hit instead of having an opportunity to make an out or an error. Conversely, a highly skilled fielder might have a comparatively low fielding percentage by virtue of reaching, and potentially missing, a greater number of balls. In order to qualify for the league lead in fielding percentage, an infielder or outfielder must appear at the specific position in at least two-thirds of his team's games (games in the outfield are not separated by position).〔Rule 10.22(c)(2). (【引用サイトリンク】publisher=Major League Baseball (MLB.com) )〕 A catcher must appear in at least half his team's games.〔Rule 10.22(c)(1). (【引用サイトリンク】publisher=Major League Baseball (MLB.com) )〕 A pitcher must pitch at least one inning for each of his team's scheduled games (however, a pitcher with fewer innings may qualify if they have more total chances and a higher average).〔Rule 10.22(c)(3). (【引用サイトリンク】publisher=Major League Baseball (MLB.com) )〕 In order to qualify for major league career records for fielding average, a player must appear in 1000 games at the position; pitchers must have at least 1500 innings. The MLB record for team fielding percentage is currently held by the 2013 Baltimore Orioles with a .99104 fielding percentage. ==See also== *Baseball fielding positions *Ultimate zone rating 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「fielding percentage」の詳細全文を読む スポンサード リンク
