In baseball and softball, the count is the number of balls and strikes the batter has. If the count reaches three strikes, the batter strikes out; if the count reaches four balls, the batter earns a base on balls (a "walk").
Usage
The count is usually announced as a pair of numbers, for example, 3–1 (pronounced as "three and one"), the number of balls followed by the number of strikes. Zero is almost always pronounced as "oh". The count is often used as adjective—an individual pitch may be referred to by the count prior to its delivery; for example, a pitch thrown on a 3–1 count is a "three-one pitch" or a "three-and-one pitch".
A count of 0–0 is rarely stated; the count is typically not mentioned until at least one pitch has been thrown. A count of 1–1 or 2–2 may be described as even. A count of 3–2 is full, which is discussed below.
The home plate umpire signals the count with the number of balls on the left hand, and the number of strikes on the right hand. (As a result, it reads backwards when viewed from the pitcher's point of view.) Individual umpires vary in how frequently they give this signal; it is often done as a reminder when there has been a slight delay between pitches, such as due to the batter stepping out of the batter's box. It can also signal the scoreboard operator that the board shows an incorrect count. Some umpires may also call out the count, although usually only the batter and catcher can hear it.
Significance
Baseball statistics measure which counts are most likely to produce favorable outcomes for the pitcher or the batter. Counts of 3–1 and 2–0 are considered advantageous to batters ("hitters' counts"), because the pitcher—faced with the possibility of walking the batter—is more likely to throw a ball in the strike zone, particularly a fastball. Counts with two strikes (except 3–2) are considered advantageous to pitchers ("pitchers' counts"). An 0–2 count is very favorable to a pitcher, who has the freedom to throw one or two pitches out of the strike zone intentionally, to get the batter to "chase" the pitch (swing at it), and strike out.
A 3–0 count tends to yield fewer hittable pitches, perhaps because the umpire is reluctant to call four straight balls and may tolerate a fourth pitch that barely misses the strike zone. Batters often "take" (do not swing at) a 3–0 pitch, since the pitcher has missed the strike zone three straight times already, and a fourth would earn the batter a walk. This is a sound strategy because the batter is more likely to eventually reach base even if the count becomes 3–1 than he is if he puts the ball in play on 3–0. It is sometimes also advantageous to take on 2–0 and 3–1.
