List of baseball jargon (B)

List of baseball jargon (B)

backdoor breaking ball

: A breaking pitch, usually a slider, curveball, or cut fastball that, due to its lateral motion, passes through a small part of the strike zone on the outside edge of the plate after appearing it would miss the plate entirely. It may not cross the front of the plate but only the back and thus have come in through the "back door." A slider is the most common version, because a slider has more lateral motion than other breaking pitches. The most famous backdoor slider may be the one that Kirk Gibson hit off of Dennis Eckersley for a game-winning home run in the first game of the 1988 World Series, which the Dodgers went on to win.


:*The fence behind homeplate, designed to protect spectators from wild pitches or foul balls.:*Catcher, sometimes "backstopper".


:Consecutively. When two consecutive batters hit home runs, they are said to hit back-to-back homers. Or a pitcher may issue back-to-back walks, and so forth.

bad-ball hitter

:A batter who excels at hitting pitches that are outside the strike zone. Notable bad-ball hitters include Yogi Berra and Vladimir Guerrero.

bad hop

:A ball that bounces in front of an infielder in an unexpected way, often as a result of imperfections in the field or the spin on the ball.


:A base.


:*A batter who sees a pitch coming toward his head may "bail out" (hit the deck).:*When two fielders are converging on a fly ball, one of them may "bail out" to avoid running into the other.:*A relief pitcher may come into the game with men on base and bail the previous pitcher out of a jam.

:While the first two examples are analogues to bailing out of a plane via parachute, the last one is akin to bailing out a boat that's on the verge of being swamped, or perhaps bailing somebody who is in trouble out of jail.


:A ruling made by an umpire against a pitching motion that violates rules intended to prevent the pitcher from unfairly deceiving a baserunner. When a balk is called, each runner can freely advance one base. The rules specify which pitching movements are illegal. The spirit of a balk is that certain movements mean that the pitcher has begun the pitch, so the runner cannot then be picked off. Some balks result from errant or unsuccessful motions, such as when the ball slips out of the pitcher's hand. Far more rare is a catcher's balk, when the catcher moves from behind the area of the plate before the pitcher starts his delivery.

ball in play

:In sabermetrics, "ball in play" and "batting average on balls in play" (BABIP) have specific technical definitions that are used to determine pitchers' ability independently of the fielding defense of a team. In this definition, a home run is not a ball in play. See Defense Independent Pitching Statistics. Also see in play.

=Baltimore chop=

:A short downward swing intended to make the ball rebound off home plate or the packed dirt immediately in front of the plate. The goal is to produce a bounce high enough so that, even if the ball can be fielded by an infielder the batter will reach first for a base hit. This was a tactic of the Baltimore Orioles of the National League in the 1890s. John McGraw is supposed to have had the earth in front of home plate compacted for this purpose. When it happens in the modern game, it is more often simply a result of poor contact that just happens to aid the batter-runner.


:A ballpark with small dimensions that encourages offense, especially home runs. A crackerbox.


:*A baseball player's term for cancelling a game because of bad weather: "I thought we were gonna get banged but we got in 5 innings.":*To hit the ball hard, especially to hit a homer. "Utley banged the game-tying home run.":*Players who are banged up are injured, though may continue to play. Example: "Banged up Braves ready for playoff rematch with Astros.":*A bang-up game is an exciting or close game. Example from a sports headline: "A Real Bang-Up Finish.":*A bang bang play is one in which the runner is barely thrown out, a very close call, typically at first base. Perhaps reflecting the "bang" of the ball in the first-baseman's glove followed immediately by the "bang" of the baserunner's foot hitting the bag.

banjo hitter

:A batter who lacks power. A banjo hitter usually hits bloop singles, often just past the infield dirt, and would have a low slugging percentage. The name is said to come from the twanging sound of the bat at contact, like that of a banjo.

base hit

:See hit.

base knock

:A single. Also see knocks.

Baseball Annie

:Female "groupie" known to "be easy" for baseball players. Susan Sarandon played such a role as the character Annie Savoy in the 1988 American film "Bull Durham."

=bases loaded=

:Runners on first, second, and third base. Also known as "bases full," "bases packed," "bases jammed," "bases juiced," or "bases chucked".


:Last place, bottom of the standings. Also cellar.


:A baserunner (shortened as "runner") is a player on the offensive team (i.e., the team at bat) who has safely reached base.

basket catch

:Catching a fly to the outfield with open glove near belt level. The signature catch of Willie Mays. It was also used in the movie Major League where Willie "Mays" Hayes makes a basket catch and as he approaches the dugout his manager says " Nice catch Hayes, don't ever (expletive) do it again!"


:* A baseball bat is a smooth contoured round wooden or metal rod used to hit the ball thrown by the pitcher. A bat's diameter is larger at one end (the barrel-end) than at the other (the handle). The bottom end of the handle is the knob. A batter generally tries to strike the ball in the sweet spot near the middle of the barrel-end of the bat, sometimes referred to as the fat part of the bat or the meat end of the bat.:* The player who uses it to strike the ball — a batter, hitter, or batsman — can be said to bat the ball.

bat around

:When each of the nine players in the lineup makes a plate appearance during a single inning, causing the inning's first hitter to return to the plate a second time.

bat the ball

:To hit the ball with the bat -- whether into fair territory or foul.


:The player who is at bat and tries to hit the ball with the bat. Also referred to as the "hitter" or "batsman."

batter's eye

:A solid-colored, usually dark area beyond the center field wall that is the visual backdrop for the batter looking out at the pitcher. It allows the batter to see the pitched ball against a dark and uncluttered background, as much for the batter's safety as anything. The use of a batter's background has been standard in baseball (as well as cricket where they are called "sight screens") since at least the late 1800s.

:One example of a batter's background is the black area in center field of Yankee Stadium. At one time, there were seats where the black area is now, but because of distractions the seats were removed and the area painted black.

batter's box

:A rectangle on either side of home plate in which the batter must be standing for fair play to resume. Only a foot and a hand out of the box are required to stop fair play.


:*The pitcher and catcher considered as a single unit. Henry Chadwick coined the term, drawing from the military sense of the term artillery battery. It also suggests a play on words, as its activities center on the batter.


:A pitcher and catcher from the same team.

batting average

:Batting average (BA) is the average number of hits per at-bat (BA=H/AB). A perfect batting average would be 1.000 (read: "one thousand"). A batting average of .300 ("three hundred") is considered to be excellent, which means that the best hitters fail to get a hit in 70% of their at-bats. Even the level of .400, which is outstanding and rare (last achieved at the major league level in 1941), suggests "failure" 60% of the time. This is part of the reason OBP is now regarded by "figger filberts" as a truer measure of a hitter's worth at the plate. In 1887, there was an experiment with including bases-on-balls as hits (and at-bats) in computing the batting average. It was effectively an early attempt at an OBP, but it was regarded as a "marketing gimmick" and was dropped after the one year. It eventually put Adrian Anson in limbo regarding his career hits status; dropping the bases on balls from his 1887 stats, as some encyclopedias do, put his career number of hits below the benchmark 3,000 total.

batting practice

:The period, often before a game, when players warm up or practice their hitting technique. Sometimes the term is used to describe a period within a game when one team's hitters have so totally dominated a given pitcher that the game resembles a batting practice session. Referred to colloquially as well as abbreviated as BP.


:When a hitter works the count, by being patient, perhaps by deliberately fouling off pitches that he can't get good wood on, he's said to be "battling."


:A strong throwing arm. A gun, a cannon, a rifle.


:A pitch intentionally thrown to hit the batter if he does not move out of the way, especially when directed at the head (or the "bean" in old-fashioned slang). The word bean can also be used as a verb, as in the following headline: "Piazza says Clemens Purposely Beaned Him." [ [ Chicago Sun-Times, July 10, 2000] .]

beat out

:When a runner gets to first base before the throw, he beats the throw or beats it out. Akin to leg out. "Greene's throw to first base pulls Gonzalez off the bag and Norris Hopper is fast enough to beat it out before Gonzalez can get his foot back on the bag." [ [ MLB Baseball Glog - ] ]

behind in the count

:Opposite of ahead in the count. For the batter: when the count contains more strikes than balls. For the pitcher: vice versa.

:If the pitcher is behind in the count, he is in increasing danger of walking the batter. If the batter is behind, he is in increasing danger of striking out.


:To hit a ball hard to the outfield or out of the park, fair or foul. "Jones belts that one deep to left . . . but just foul."


:*"The bench" is where the players sit in the dugout when they are not at bat, in the on-deck circle, or in the field.:*"The bench" may also refer to the "players" who are not in the line-up but are still eligible to enter the game. "LaRussa's bench is depleted because of all the pinch hitting and pinch running duties it's been called on to perform tonight."

bench jockey

:A player, coach or manager with the talent of annoying and distracting opposition players and umpires from his team's dugout with verbal repartee. Especially useful against those with rabbit ears.


:A curveball.

big as a grapefruit

:When a hitter sees the pitch so well that it appears to be larger than its actual size, he may describe the ball as being "as big as a grapefruit." "After hitting a 565-foot home run, Mickey Mantle once said, 'I just saw the ball as big as a grapefruit'. During a slump, Joe 'Ducky' Medwick of the St. Louis Cardinals said he was 'swinging at aspirins.'" [Robert Roy Britt, "Baseball Science: Better Hitters See Ball as Bigger," [ "Live Science", December 15, 2005.] ]

big fly

:A long home run.

big inning

:The opposite mentality of small ball, if a team is thinking "big inning" they are focusing on scoring runs strictly through base hits and home runs, as opposed to bunts or other sacrifices. More generically, a "big inning" is an inning in which the offense scores a large number of runs, usually four or more.

big leagues

:Major League Baseball


:The big leagues, major leagues, "the Show." If you're in the bigs you're a big leaguer, a major leaguer.

=bleacher seats=

:Bleacher seats (in short, bleachers) are uncovered seats that are typically tiered benches or other inexpensive seats located in the outfield or in any area past the main grandstand. The term comes from the assumption that the benches are sun-bleached. "Bleachers" is short for the term originally used, "bleaching boards". Fans in the bleacher seats are sometimes called bleacher bums or bleacher creatures


:A weakly hit ground ball that goes for a base hit. A scratch hit. "Dunn walked to bring up Morra, who jumped on the first pitch he saw and hit a bleeder that didn’t leave the infield, driving in Gradwohl." [ [ Hillsdale High School ] ]


:A ball that is hit so hard that it seems to generate it's own heat may be said to have been blistered. "Chapman then blistered a ball toward left-center, and Knoblauch raced back, moving smoothly, and made the catch with his arm outstretched." [Buster Olney, "BASEBALL: No Adventures as Knobloch Starts Over in Left," [ New York Times] , March 23, 2001.]

block the plate

:A catcher who puts a foot, leg, or whole body between home plate and a runner attempting to score, is said to "block the plate." Blocking the plate is a dangerous tactic, and may be considered obstruction ("Official Rules of Baseball, Rule 2.00 (Obstruction)").


:A blooper or bloop is a weakly hit fly ball that drops in for a single between an infielder and an outfielder. Also known as a "bloop single".


:*To blow a game is to lose it after having the lead. "We had the game in hand and we blew it.":*To blow a pitch by a hitter is to throw a fastball that that batter is unable to catch up to.:*To blow a save is to lose a lead or the game after coming into the game in a "save situation." This has a technical meaning in baseball statistics.:*A hit, typically a home run: "Ortiz's Blow Seals Win.":*A blow-out is a game in which one team wins by many runs. Headline: "Zito Shines as the Giants Blow Out the Dodgers."

blown save

:A blown save (BS) is charged to a pitcher who enters a game in a save situation but allows the tying run (and perhaps the go-ahead run) to score. If the pitcher's team does not come back to win the game, the pitcher will be charged with both a loss and a blown save. The blown save is not an officially recognized statistic by Major League Baseball. But analysts and sportscasters count blown saves to characterize the "record" of closers in a way that's analogous to won-loss records of starters. "Jones has made 31 out of 34 saves" or "Jones has 31 saves and 3 blown saves."


:A lopsided win, a laugher.


:Rhymes with "closer". A closer who seems to get more blown saves than saves.


:A term commonly used by players to address an umpire, referring to the typical dark blue color of the umpire's uniform. A derogatory term in professional baseball. Usually when complaining about a call: "Oh, come on, Blue!"


:A home run.

bonehead play

:A bonehead play or "boner" is a mental mistake that changes the course of a game dramatically. A play where there is an obvious loss of focus and a bad choice was made when the alternative was clear.
* See "Merkle's boner".

bonus baby

:A young player who received a signing bonus.

bonus baseball

:Extra innings. Also called "bonus cantos" by Yankees announcer Michael Kay.


:Made an error, kicked it – typically referring to a misplay on a ground ball. "Miguel Cabrera hit a ground ball to Alex S. Gonzalez, who booted the ball. Had Gonzalez fielded the ball properly, the Cubs could have ended the half-inning with a double play." []

bottom of the inning

:The second half or "last half" of an inning, during which the home team bats, derived from its position in the line score.


:*The vicinity of the pitcher's mound. Baseball announcers will sometimes refer to a batted ball going back through the pitcher's mound area as having gone through the box, or a pitcher being removed from the game will be said to have been knocked out of the box. In the early days of the game, there was no mound; the pitcher was required to release the ball while inside a box drawn on the ground. Even though the mound has replaced the box, this terminology still exists.:*Also, the batter's box, the area within which the batter stands when hitting. The batter must be in the box for the pitcher to pitch.

=box score=

:The statistical summary of a game. The line score is an abbreviated version of the box score, duplicated from the field scoreboard. Invention of the box score is credited to Henry Chadwick.


:*batting practice.:*Devotees of baseball research also sometimes refer to Baseball Prospectus as BP.


:Bats right; used in describing a player's statistics, for example: John Doe (TR, BR, 6', 172 lbs.)

bread and butter

:A player's greatest or most reliable skill. For example: "The curveball is this pitcher's bread and butter pitch." From the more general expression, "bread and butter", denoting any person's most basic source of nourishment and strength.


:The Break is the "All-Star Break", the 3-day period roughly halfway through the regular season during which the all-stars of the American League play a game against the all-stars of the National League. It's also a common reference point for comparing a player's statistics: before the break vs. after the break; the first half vs. the last half of the season (even though the "last half" is shorter than the "first half" — about 45% of the games remain to be played).

breaking ball

:Any pitch that markedly deviates from a "straight" or expected path due to a spin used by the pitcher to achieve the desired effect. Some examples are the curveball, the slider and the screwball.

break one off

:To throw a curveball.

break open the game

:When a team gains a multiple-run lead, perhaps in a single rally that expands their lead, the game may be said to be "broken open." "The Padres broke the game open with five runs in the fifth, thanks to three errors by the Cubs, who have dropped 12 of 14." [ [ - Cubs sliding, Padres rising ] ]


:To pitch; often used for a fastball: bring the gas, bring the heat, bring it.

Bronx Bombers

:A nickname for The New York Yankees.


:A batter who strikes out looking, especially if the batter did not move his bat at all. This term is mainly used by sports commentators.


:A pitch intentionally thrown close to a batter to intimidate him, i.e., to "brush him back" from the plate. Also a purpose pitch or chin music. Archaic usage: "a blowdown." [David Shulman, "Baseball's Bright Lexicon," "American Speech" 26, No. 1 (February 1951): 29-34.]

buck and change

:A player batting between .100 and .199 is said to be batting "a buck and change" or, more specifically, the equivalent average in dollars (bucks) and cents (change). Example: A batter batting .190 is said to be batting "a buck ninety". Major leaguers with a batting average this low will very likely be demoted down to AAA for seasoning or even released outright. See also Mendoza line.


:*The area used by pitchers and catchers to warm up before taking the mound when play has already begun. This area is usually off to the side along either the left or right base line, or behind an outfield fence. It is almost never in fair territory, presumably due to the risk of interference with live action. A rare exception was at New York's Polo Grounds where the bullpens were in the deep left and right center field quarter-circles of the outfield wall.:*A team's relief pitching corps (so named because the relievers are in the bullpen during games).

:It is thought to have been named as the "bull pen" either because the relief pitchers spend time "shooting the bull" or because early billboards along the walls advertised Bull Durham, a brand of chewing tobacco.


:To deliberately bat the ball weakly to a particular spot on the infield by holding the bat nearly still and letting the ball hit it. Typically, a bunt is used to advance other runners and is then referred to as a sacrifice or a sacrifice hit or a sacrifice bunt. When done correctly, fielders have no play except, at best, to throw the batter-runner out at first base.

:Speedy runners also bunt for base hits when infielders are playing back. In such a situation, left-handed hitters may use a drag bunt, in which they start stepping towards first base while completing the bunt swing. Even the great slugger Mickey Mantle would drag bunt once in a while, taking advantage of his 3.1 second speed from home to first base. Currently, Ryan Zimmerman of the Nationals is notable in that he is a right-handed hitter who uses drag bunts successfully.

bush league

:A slang term used to describe play that is of minor league or unprofessional quality. The "bushes" or the "sticks" are small towns where minor league teams may operate, the latter term also used in the acting profession, famously in the "Variety" headline of July 17, 1935, "Sticks nix hick pix", meaning small towns reject motion pictures about small towns.

bust him in

:To throw a fastball in on the hitter's hands. Also: tie him up , in the kitchen.

butcher boy

:A strategy where the hitter first shows he intends to bunt, pulls back the bat when the pitcher begins the delivery, and takes a quick swing at the pitch. Generally used by weaker hitters such as pitchers.
