Left fielder
In baseball, a left fielder (LF) is an outfielder who plays defense in left field. Left field is the area of the outfield to the left of a person standing at home plate and facing towards the pitcher's mound. In the numbering system used to record defensive plays, the left fielder is assigned the number 7.
Position description
Outfielders must cover large distances - speed, instincts, and quickness in reacting to the ball are key. They must be able to catch fly balls above their head and on the run. They must be able to throw the ball accurately over a long distance to be effective; they must also learn to judge whether to attempt a difficult catch and risk letting the ball get past them, or to instead allow the ball to fall in order to guarantee a swift play and prevent the advance of runners. Left fielders must also familiarize themselves with the varying configurations of different ballparks' foul territory, and prevent balls hit down the foul lines from getting past them into the left field corner. Amateur players may find it difficult to concentrate on the game, since they are so far from the action. Emphasizing the correct position will give outfield players something to concentrate on at each pitch. Hits to left field tend to curve toward the left field foul line, and left fielders must learn to adjust to that.
