A baseball term that refers to a count of three balls and two strikes during the course of an at bat.
A full count signifies that an additional ball thrown by a pitcher will result in a base on balls (a walk), whereas an additional called or swinging strike three will result in a strikeout. It should be noted that additional foul ball strikes that leave play will not change the count, as a foul ball cannot be counted as third strike. The pitch following a full count is often referred to as the "payoff pitch", as a pitcher must attempt to get the batter out without throwing another ball. Baserunners will often run upon the delivery of this pitch as they anticipate the batter making contact.
