. It is usually announced as a pair of numbers, for example, 3-1 , with the first number being the number of balls and the second being the number of strikes.

An individual pitch may also be referred to by the count prior to its delivery, for example, a pitch thrown with a count of three balls and one strike would be called a "three-one pitch."

A 3-2 count—that is, one with the maximum number of balls and strikes—is referred to as a full count
Full count
In baseball and softball, a full count is the common name for a count where the batter has three balls and two strikes. The term may derive from older scoreboards, which had three spaces for balls and two for strikes, since this is the maximum number of each that can be achieved before some type...

. A count of 1-1 or 2-2 is called even. Zero is always pronounced "oh," although a 0-0 count is rarely expressed as such—the count is typically not mentioned until at least one pitch has been thrown.

 will signal the count with the number of balls on his left hand, and the number of strikes on his 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 the batter stepping out of the batter's box). It can also be a signal to the scoreboard

Catcher
Catcher is a position for a baseball or softball player. When a batter takes his turn to hit, the catcher crouches behind home plate, in front of the umpire, and receives the ball from the pitcher. This is a catcher's primary duty, but he is also called upon to master many other skills in order to...

Base on balls
A base on balls is credited to a batter and against a pitcher in baseball statistics when a batter receives four pitches that the umpire calls balls. It is better known as a walk. The base on balls is defined in Section 2.00 of baseball's Official Rules, and further detail is given in 6.08...

Fastball
The fastball is the most common type of pitch in baseball. Some "power pitchers," such as Nolan Ryan and Roger Clemens, have thrown it at speeds of 95–106 mph and up to 108.1 mph , relying purely on speed to prevent the ball from being hit...

.

Somewhat surprisingly, in general, a 3-0 count tends to yield fewer hittable pitches, depending on the situation. (Baseball fans have often suggested that this is because umpires are reluctant to call four straight balls and as a result "ease up" on the fourth pitch, treating it as having a wider strike zone.) Often batters will take (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.

Batters often take the 3-0 pitch, by not swinging even if the pitch is hittable. 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. In some situations, it is also advantageous to take on 2-0 and 3-1.

Counts with two strikes (except 3-2) are considered pitchers' counts. An 0-2 count is very favorable to a pitcher. In such a count, the pitcher has the freedom to throw one (or sometimes two) pitches out of the strike zone intentionally, in an attempt to get the batter to chase the pitch (swing at it), and potentially strike out
Strikeout
In baseball or softball, a strikeout or strike-out occurs when a batter receives three strikes during his time at bat. A strikeout is a statistic recorded for both pitchers and batters....
