Plate Appearance
Each player's turn at the plate is a plate appearance. When
the batter hits a fair ball, he must run to first base, and
may continue
or stop at any base unless he is put out. A successful hit where
the batter reaches only first base is a single; if he reaches
second base, a double; or third base, a triple. A hit that allows
the batter to touch all bases in order on the same play is a
home run, whether or not the ball is hit over the fence. If a
player has hit all four types of base hits in a single game,
he is said to have "hit for the cycle." Once a runner
is held to a base, he may attempt to advance at any time, but
is not required to do so unless the batter or another runner
displaces him.
Depending on the way the ball comes off the bat, the play has
different names. A batted ball is called a fly ball if it was hit
in the air in a way causing the fielder to catch it on its descent,
or a line drive if it is hit in the air, but almost level to the
ground. A batted ball which is not hit into the air, and which
touches the ground within the infield before it can be caught,
is called a ground ball.
Once the batter and any existing runners have all stopped at a
base or been put out, the ball is returned to the pitcher, and
the next batter comes to the plate. After the opposing team bats
in its own order and three more outs are recorded, the first team's
batting order will continue again from where it left off.
