Glossary of baseball (A)

A

A-Ball or Single-A

"Single-A" is the second-lowest grouping of modern affiliated minor league baseball, with sub-categories of "High-A", "Low-A", and "Short-Season A". The California League, Florida State League, Midwest League and the Carolina League are categorized as "Single-A".

AA

• "Double-A" (AA) is the second-highest level of minor league baseball (below AAA), and includes the Eastern League, the Southern League, and the Texas League.
• "AA" is also the abbreviation for the American Association, which has been the name of numerous professional baseball leagues: a short-lived major league of the 19th century, a minor league for much of the 20th century, and an independent minor league unaffiliated with Major League Baseball.

AAA

"Triple-A" is the highest level of minor league baseball. This level includes the Pacific Coast League, the International League, and the Mexican League.

AAAA player

"Four-A player" (alternatively, "Quadruple-A player") is a term for a minor-league player who is consistently successful in the high minor leagues, but cannot translate that into success at the major-league level. Poor management can be responsible.

aboard

When a runner is on base. When there are runners safely on base, there are "runners aboard".

ace

The best starting pitcher on the team, who is usually first on a pitching rotation.

advance a runner

To move a runner ahead safely to another base, often the conscious strategy of a team that plays small ball. Even if a batter makes an out, he may be regarded as having a less negative outcome to his plate appearance if he advances a runner into scoring position or from second to third, thereby increasing the chances of that runner scoring a run later in that inning compared to those chances had that runner not advanced while that out is made. In certain situations, batters deliberately bunt for an out and thereby sacrifice themselves in order to advance a runner to second or third base.

ahead in the count

A term that signifies whether the batter or pitcher possesses the advantage in an at-bat. If a pitcher has thrown more strikes than balls to a batter in an at-bat, the pitcher is ahead in the count; conversely, if the pitcher has thrown more balls than strikes, the batter is ahead.

If the pitcher is ahead in the count, the batter is in increasing danger of striking out. If the batter is ahead, the pitcher is in increasing danger of walking him.

aim the ball

Sometimes when a pitcher tries a bit too carefully to control the location of a pitch, he is said to "aim the ball" instead of throwing it. This is a different meaning of "aim" from the situation in which a pitcher aims a pitch at a batter in an effort to hit him.

airmail

Slang for a fielder's errant throw that sails high over the player to whom he intended to throw the ball. For example, if the third baseman were to throw the ball over the first baseman's head and into the stands, he is said to have "airmailed" the throw. "But Chandler airmailed her throw to third into the dugout...".

Alabaster Blast

Coined by Pittsburgh Pirates announcer Bob Prince. A Baltimore Chop base hit that would go higher than normal due to the extraordinarily hard infield at Forbes Field

alley

Also "gap" or "power alley", the space between the leftfielder and the centerfielder, or the rightfielder and centerfielder. If a batter hits the ball "up the alley" with enough force, he has a stronger chance of advancing beyond first base and being credited with an extra-base hit. Typically, this is an appropriate term for describing a line drive or ground ball; fly balls that hit the wall are not normally described this way.

American League (AL)

Main article: American League

The junior of the two existing Major Leagues.

American League Championship Series (ALCS)

Main article: American League Championship Series

The season's final best-of-seven playoff series which determines the American League team that will advance to the World Series. The ALCS–like its analog, the NLCS–came into being in 1969. The ALCS winner takes the American League pennant and the title of American League Champion for that season. The winners of the American League Division Series have met in the ALCS since 1995.

American League Division Series (ALDS)

Main article: American League Division Series

The first round of the league playoffs. The winners of the three divisions and the winner of the Wild Card Game are paired off in two best-of-five series, the winners of which advance to the ALCS.

Annie Oakley

A free ticket to attendance at a ballgame or to first base (a "free pass" or "base on balls").

appeal play

Main article: appeal play

A play in which the defense has an opportunity to gain a favorable ruling from an umpire by addressing a mistake by the offense or seeking the input of another umpire. Appeals require the defense to literally make an appeal to an appropriate umpire; He will not announce, for example, runners failing to touch a base, batting out of order, or unchecked swings until an appeal is made.

Arizona Fall League (AFL)

Main article: Arizona Fall League

A short-season minor league in which high-level prospects from all thirty Major League Baseball clubs are organized into six teams on which players have the opportunity to refine and showcase their skills for evaluation by coaches, scouts, and executives. Such teams are referred to as "scout teams" and "taxi squads".

arm

May be used as a literal reference to a pitcher's arm ("A's trade two young arms to Kansas City...",) or in reference to players as armaments ("...Anthopoulos is just stockpiling arms in an attempt to lure a trade...").

around the horn

The infielders' practice of throwing the ball to each other after recording an out, provided that there are no runners on base. The purpose is as much traditional as anything else, but also serves to keep the infielders' throwing arms active. Typically, if an out is made at first base, the first baseman will throw to the second baseman, who throws to the shortstop, who throws to the third baseman, who returns the ball to the pitcher. Patterns vary from team to team, but the third baseman is usually the last infielder to receive a throw, regardless of the pattern.

Throwing the ball around the horn is also done after a strikeout with no baserunners. The catcher will throw the ball to the third baseman, who then throws it to the shortstop, who throws it to the second baseman. Rarely does the second basemen throw the ball to the first baseman. Most often, it goes back to the third baseman, who returns it to the pitcher. Some catchers, such as Ivan Rodriguez, prefer to throw the ball to the first baseman, who then begins the process in reverse. Some catchers determine to whom they will throw based on the handedness of the batter (to first for a right-handed batter because the line to the first baseman is not blocked and vice versa) or whether the team is in an overshift, when the third baseman would be playing close to where the shortstop normally plays and would require a harder throw to be reached.

An additional application of this term is when a 5-4-3 or 6-4-3 double play has occurred, which mimics the pattern of throwing the ball around the horn.

ash

An old-fashioned word referring to the baseball bat, which is typically made of wood from an ash tree. "...the shrewd little manager substitutes a fast runner for a slow one, and sends in a pinch hitter when the man he takes out is just as good with the ash as the man he sends in".

aspirin

Not to be confused with pill.

Slang for a fastball that is especially hard to hit due to its velocity and/or movement, in reference to the difficulty of making contact with something as small as an aspirin tablet. May additionally reference batters seeing a pitched ball as relatively smaller than normal, a potential psychological effect on batters who are in a slump.

assist

Main article: assist (baseball)

The official scorer awards an assist to every defensive player who fields or touches the ball (after it has been hit by the batter) prior to a putout, even if the contact was unintentional. For example, if a ball strikes a player's leg and bounces off him to another fielder, who tags the baserunner, the first player is credited with an assist.

A fielder can receive only one assist per out recorded. A fielder also receives an assist if a putout would have occurred, had not another fielder committed an error.

asterisk

A slang term for a baseball record broken by a person who otherwise cheated (or is widely perceived as having done so) in attaining the record–such as using performance-enhancing drugs–or when referring to the player that breaks it. Barry Bonds was regularly greeted with banners and signs that bore an asterisk during the 2007 season when he broke Hank Aaron's career home run record. Additionally, Roger Maris broke Babe Ruth's single-season home run record on the last day of a 162-game regular season, whereas during Ruth's career the regular season was 154 games long; Baseball Commissioner Ford Frick declared that Maris' record should be listed separately from Ruth's (contrary to popular belief no asterisk was mentioned or used in this case), a decision not formally reversed until 1991.

at 'em ball

or "atom ball;" slang for a ball batted directly at a defender.

at bat

Main article: At bat

A completed plate appearance by a batter which results in a base hit or a non-sacrifice out. At-bats (or "times at bat") are used for the calculation of a player's batting average and slugging percentage. Note that a plate appearance is not recorded as an "at-bat" if the batter reaches first base as a result of a base on balls, or hit by pitch, nor if he executes a sacrifice bunt or sacrifice fly.

Occasionally a batter may be at the plate when the third out of the inning is made against a base-runner; in this case the batter will lead off the next inning with a clean strike count and his interrupted plate appearance is not counted as an at-bat.

at the letters

A pitch that crosses the plate at the height of the letters of the team's name on the shirt of the batter's uniform is said to be "at the letters", "letter-high" or "chest-high".

ate him up

Slang expression of the action of a batted ball that is difficult for a fielder to handle.

ate the ball

See: eat the ball

attack the strike zone

Slang for pitching aggressively by throwing strikes, rather than trying to trick hitters into swinging at pitches out of the strike zone or trying to "nibble at the corners" of the plate. Equivalent phrases are "pound the strike zone" and "challenge the hitters".

automatic double

A batted ball in fair territory which bounces out of play (e.g. into the seats) entitles the batter and all runners on base to advance two bases but no further. This term is used by some commentators in lieu of ground rule double, which refers to ground rules in effect at each ballpark.

automatic strike

A strike is deemed "automatic" when the pitcher grooves a strike–typically on a 3-0 count–with such confidence that the batter takes the pitch without swinging at it.

away

• A pitch outside the strike zone, on the opposite side of the plate as the batter, is referred to as being "away", in contrast to a pitch thrown between the plate and the batter that known as "inside".
• Slang for "outs". For example, a two out inning may be said to be "two away"; A strike out may be referred to as "putting away" the batter.
• Games played at an opponent's home field are "away games". The visiting team is sometimes called the "away" team.
