Jimmy Rollins holds the single season record for most plate appearances, at 778. 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.
