In
baseball, a
single is the most common type of
base hit, accomplished through the act of a
batter safely reaching
first base by hitting a
fair ball (thus
becoming a runner) and getting to first base before a fielder puts him out. As an exception, a batter-runner reaching first base safely is not credited with a single when an infielder attempts to put out another runner on the first play; this is one type of a
fielder's choice. Also, a batter-runner reaching first base on a play due to a fielder's error trying to put him out at first base or another runner out (as a fielder's choice) is not credited with a single.
