Calculating

after having already started his turn at bat. In this case, the pinch hitter would receive the plate appearance (and potential of an at-bat) unless the original batter is replaced when having 2 strikes against him and the pinch hitter subsequently completes the strikeout.

Other uses
In common terminology, the term "at bat" is sometimes used to mean "plate appearance" (for example, "he fouled off the ball to keep the
at bat alive"). The intent is usually clear from the context, although the term "official at bat" is sometimes used to explicitly refer to an
at bat as distinguished from a
plate appearance. However, terms such as
turn at bat or
time at bat are synonymous with
plate appearance.
Scoring
Section 10 of the official rules states what an at bat is not:
"Number of times batted, except that no time at bat shall be charged when a player:
(i) hits a sacrifice bunt or sacrifice fly;
(ii) is awarded first base on four called balls;
(iii) is hit by a pitched ball; or
(iv) is awarded first base because of interference or obstruction "
The main use of the plate appearance statistic is in determining a player's eligibility for leadership in some offensive statistical categories, notably
