A pitch – usually a fastball – that nearly hits the batter and “brushes him back.”
The area designated for pitchers to warm up before they enter the game.

The origin of the term in a baseball context is not universally known or agreed upon.
An offensive play in which the batter turns his body to face the pitcher and holds the bat out in front of him. The batter attempts to hit the pitch softly into the ground so that one of the infielders must run up and field it. The most common type of bunt is a sacrifice, which takes place with one or more runner on base. In this case, the batter bunts the ball so that the fielders only have time to record the out at first base, allowing the other runner(s) to advance.

The two lines that extend out from home plate through first and third base, respectively, all the way to the outfield fence. Foul lines separate fair and foul territory and are typically marked with chalk or paint.
The foul pole is effectively the end of the foul line. Foul poles are positioned at the outfield fence and are used to determine whether a ball that travels over the fence was fair or foul.

Hit and run
A strategic play in which the base runner(s) attempt to steal the next base when the pitcher pitches the ball and the batter swings at the pitch to try to put the ball in play.

A slang term for the third-base position. The term refers to the fact that the third baseman often plays very close to the batter and must therefore occasionally react to sharply hit balls.
The area of the field contained within the baselines. On many fields, the majority of the infield is covered with grass.
This is called by an umpire when there are runners on first and second base or the bases are loaded and there are less than two outs, and the batter hits a fly ball that stays inside the confines of the infield. When the call is made, the batter is automatically out and the base runners are free to advance, but face no risk of a force out regardless of whether the ball is caught.
A player whose defensive position is located on the infield. The term typically refers to first basemen, second basemen, third basemen and shortstops. However, the pitcher and catcher are considered infielders, as well.
The means of breaking up a game. Depending on the level of play, games consist of a different, predetermined amount of innings (nine innings is the official standard). In each inning, both teams have a turn to play both offense and defense. Each half of the inning is completed when three outs are recorded.
Occurs when a pitcher intentionally throws four balls far outside the strike zone. This is usually done strategically when a base is open and/or when facing a particularly dangerous hitter.
This is called when a batter or runner obstructs a defender from making a play on the ball (in which case, an out is called), or when a defensive player impedes a runner in the baseline (in which case, the runner is awarded the base).
A slang term for a pitcher who throws an unusually high number of breaking balls and off-speed pitches, typically because he does not throw particularly fast. Therefore “junk” refers to slow breaking balls and offspeed pitches.
The official scorekeeping shorthand symbol for a strikeout. In the scorebook, a backwards K designates a strikeout looking.
A pitch in which the pitcher places his fingernails on the seams and uses his knuckles to push the ball out of his hand. Ideally, knuckleballs do not rotate during their flight and therefore have an unpredictable trajectory. The pitch is uncommon and very difficult to master.

Leads are also short enough so that the runner to can get back to the base if the defense tries to tag him out.
The player hitting in the first position in the batting order. Also the batter who bats first at the start of each inning is considered to be “leading off” the inning.
The area of the field that constitutes the left third of the outfield. It is also one of the nine defensive positions.

A defensive player whose position is left, center or right field.

A pitch that’s thrown on a full count.
A popular game often enjoyed by players before the start of a baseball game. Pepper is played with one person holding a bat, and two or more persons standing several feet away, pitching him the baseball.

The game is designed as a warm-up routine and helps sharpen fielding skills and hand-eye coordination.
The term for when a pitcher retires every batter on the opposing team, not allowing a single baserunner for the entire game. Even more uncommon than a no-hitter, perfect games are considered an outstanding achievement.
Another term for a rundown, a play in which a runner is caught between two bases and two or more fielders attempt to chase him down and tag him out.
A play that takes place with one or more runners on base, usually in order to prevent the runners from attempting to steal the next base.

Pick-off attempts do not frequently result in outs, as runners typically lead off the base only far enough so that they can get back safely if necessary.

Slang term for a batted ball that’s not hit particularly hard, but that finds its way through the infield for a base hit.
Nickname for the National League, which has existed since 1876 (compared to the American league, which was founded in 1901).
One of two legal positions in which a pitcher must be when he delivers a pitch.

A slang term for a left-handed pitcher. It is generally agreed upon that the term originated in the early days of baseball, when stadiums were built with home plate pointing west, first base pointing south, second base pointing east, and third base pointing north. The reason for this design was, during games played in the afternoon and evening, the sun would set behind home plate, keeping it out of the batters’ eyes, as well as those of the fans sitting behind home plate. As such, when a left-handed pitcher stands on the mound, his left arm (and paw) is facing south, towards first base.

By rule, the strike zone spans the width of home plate and extends from the batter’s knees to the bottom of his shoulders. The home plate umpire stands behind the catcher and rules whether each pitch is in the strike zone. As such, the strike zone tends to be somewhat subjective.
This occurs when a batter has three strikes in a single plate appearance. The third strike must be either a called strike, a swing-and-miss or a foul tip.
An uncommon style of pitching in which the pitcher drops his elbow down so that his throwing motion is such that he releases the ball from below his waist.
A squeeze play (see above) in which the runner on third base runs towards home plate as the pitcher delivers the pitch. The suicide squeeze is rare, and is so named because, if the batter is unable to bunt the ball, the runner that was on third base is likely to be caught in the baseline and tagged out.
The contact point on the bat that creates the hardest hits.
Term for a batter that is able to hit both right handed and left handed. Typically, a switch hitter will bat left handed when facing a right-handed pitcher, and right handed when facing a left-handed pitcher.

A run that occurs as the result of a defensive error.
Another term for a base on balls. It occurs after four balls are thrown in a single plate appearance.

One of two legal positions in which a pitcher stands before delivering a pitch. The pitcher stands on the rubber facing home plate and typically steps back with one foot, kicks his front leg into the air and projects his throwing arm forward. Pitchers usually use the wind-up with no runners on base, because it takes longer to deliver a pitch. Many pitchers are more comfortable pitching from the wind-up position.
