An outfielder is a person playing in one of the three defensive positions in baseball or softball, farthest from the batter. These defenders are the left fielder, the center fielder, and the right fielder. As an outfielder, their duty is to catch fly balls and ground balls then to return them to the infield for the out or before the runner advances, if there are any runners on the bases. Outfielders normally play behind the six defensive players located in the infield: the pitcher, catcher, first baseman, second baseman, third baseman, and shortstop. The left fielder and right fielder are named based on their positions relative to the center fielder when looking out from home plate, with the left fielder positioned to the left of the center fielder and the right fielder positioned to the right.
