What is "plate appearance"

n. (context baseball English) A batter completed turn in the batter's box, that usually results in an at-bat or walk, but may also result in a hit-by-pitch, sacrifice fly, sacrifice hit, or catcher's interference. If the third out of an inning is recorded prior to completion of the batter's turn, no plate appearance is credited to the batter, and he will lead off his team's next turn at bat.

In baseball statistics, a player is credited with a plate appearance (denoted by PA) each time he completes a turn batting. A player completes a turn batting when: he strikes out or is declared out before reaching first base; or he reaches first base safely or is awarded first base (by a base on balls, hit by pitch, or catcher's interference); or he hits a fair ball which causes a preceding runner to be put out for the third out before he himself is put out or reaches first base safely (see also left on base, fielder's choice, force play). In other words, a plate appearance ends when the batter is put out or becomes a runner. A very similar statistic, at bats, counts a subset of plate appearances that end under certain circumstances.
