'A' stands for Assist and is a defensive statistic. Players are given assists when they help in getting a runner out but do not actually make the putout. For example, if a batter hits a ground ball to the shortstop and the shortstop throws thebatter out at first base, the shortstop is credited with an assist and the first baseman is credited with a putout.
