Backstop (baseball)

B

backdoor breaking ball

:A breaking pitch, usually a Slider (baseball), slider, curveball, or cut fastball that, due to its lateral motion, passes through a small part of the Glossary of baseball (S)#strike zone, strike zone on the outside edge of the Glossary of baseball (H)#home plate, plate after seeming as if 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 Glossary of baseball (B)#breaking ball, breaking pitches (it curves down and 'slides' across the zone).

backstop

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

back-to-back

:Consecutive. 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 Glossary of baseball (I)#infielder, infielder in an unexpected way, often as a result of imperfections in the playing surface or the spin on the ball.

bag

:A base. Also, a two-bagger is a double or two-base hit; a three-bagger is a triple or three-base hit; a four-bagger is a home run.

bail

:*A batter who sees a pitch coming toward his head may "bail out" (Glossary of baseball (H)#hit the deck, 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 Glossary of baseball (R)#reliever, relief pitcher may come into the game with men on base and bail the previous pitcher out of a Glossary of baseball (J)#jam, 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 on the verge of being swamped, or perhaps bailing somebody out of jail.

balk

:A ruling made by an Glossary of baseball (U)#umpire, umpire against a Glossary of baseball (P)#pitch, pitching motion that violates rules intended to prevent the Glossary of baseball (P)#pitcher, pitcher from unfairly deceiving a Glossary of baseball (B)#baserunner, baserunner. When a balk is called, each Glossary of baseball (B)#baserunner, runner can freely advance one base. In professional baseball, a balk does not instantly result in a dead ball. If a pitch is thrown and all runners advance one base due to a hit, play continues and the balk is ignored. This rarely occurs because when the balk is called the pitcher normally stops his delivery and the umpire declares the ball dead and awards the bases. In non-professional baseball (high school and college), a balk instantly results in a dead ball and the runners are awarded their bases. The rules specify which pitching movements are illegal. Commonly called balks are failure for the pitcher to come to a set position (or coming set multiple times) or failure to step in the direction of the base he is throwing toward. The spirit of a balk is that certain movements mean the pitcher has begun the pitch, so the runner cannot then be Glossary of baseball (P)#pickoff, 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 (applicable only during an intentional walk).

ball

:A Glossary of baseball (P)#pitch, pitch that misses the Glossary of baseball (S)#strike zone, strike zone and is not Glossary of baseball (S)#swing, swung at by the Glossary of baseball (B)#batter, batter. (For the physical object used in the game, see baseball (ball).)

ball in play

:In sabermetrics, "ball in play" and "Defense Independent Pitching Statistics, 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, Defense Independent Pitching Statistics. Also see Glossary of baseball (I)#In play, in play.

:A ball hit forcefully into the ground near home plate, producing a bounce high above the head of a fielder. This gives the batting (baseball), batter time to reach first base safely before the ball can be fielded. An important element of Baltimore Orioles (19th century), Baltimore Orioles coach John McGraw's "Inside Baseball (strategy), inside baseball" strategy, the technique was popularized during Major League Baseball's dead-ball era, during which baseball teams could not rely on the home run.

:To give the maximum bounce to a Baltimore chop, Orioles groundskeeper Tom Murphy packed the dirt tightly around home plate, mixed it with hard clay and left the infield unwatered. Speedy Orioles players like McGraw, Joe Kelley, Steve Brodie (baseball), Steve Brodie, and Willie Keeler most often practiced and perfected it.

:In modern baseball, the Baltimore chop is much less common, usually resulting when a batter accidentally swings over the ball. The result is sometimes more pronounced on those diamonds with artificial turf. The technique still sees use in softball.

banana stalk

:A bat made with an inferior, low-quality grade of wood. See also Glossary of baseball (M)#morning journal, morning journal

bandbox

:A ballpark with small dimensions that encourages offense, especially home runs. A Glossary of baseball (C)#crackerbox, crackerbox. (see: Baker Bowl and Citizens Bank Park, Citizens Bank Ballpark)

bang

:*Cancelling a game because of bad weather: "I thought we were gonna get banged but we got in five innings."
:*To hit the ball hard, especially to hit a homer. "Chase Utley, 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.
:*bang it inside is when a pitcher throws on the inside of the plate, and the batter cannot get his arms extended enough to hit the ball, which goes "bang" into the catcher's mitt. "It was an unbelievable feeling and a feeling I'll never forget," Johnny Giavotella, Giavotella said. "Max Scherzer, Scherzer was trying to come in on me all day. He was banging me inside and I couldn't get my hands extended. I guess he missed over the plate that time and I got my hands inside and barreled it up and it flew out of the park."

banjo hitter

:A Glossary of baseball (B)#batter, batter who lacks power. A banjo hitter usually hits bloop singles, often just past the infield dirt, and would have a low Glossary of baseball (S)#slug, slugging percentage. The name is said to come from the twanging sound of the bat at contact, like that of a banjo. See also Glossary of baseball (P)#Punch and Judy hitter, Punch and Judy hitter.

barehand it

:Refers to when a fielder catches a ball with the hand not covered by his glove.

:See Glossary of baseball (S)#sweet spot, sweet spot.

base hit

:See Glossary of baseball (H)#hit, hit.

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".
:*Infamous Ruth Ann Steinhagen was the first "Baseball Annie". She became obsessed with Cubs and then Phillies first baseman Eddie Waitkus. She shot him through the chest, nearly killing him in 1949. This story inspired the 1952 novel ''The Natural''.

bases loaded

:Runners on first, second, and third bases. Also known as "bases full", "bases packed", "bases jammed", "bases juiced", "bases chucked", or "bases drunk". This presents a great run (baseball), scoring opportunity for the batting (baseball), batting team, but it also presents an easy double play opportunity for the defense (sport), defense. Causing the bases to become loaded is called loading the bases. A batter is often intentionally walked when there are runners on 2nd and 3rd base to make it easier for the defense to record more than one out.

:A bases-loaded situation is the only time there is a force play, force at home plate.

:Since there is no additional room to place the batter (baseball), batter, should he be awarded first base from a base on balls or hit by pitch, one run will score due to the third-base player's being forced home. Chronologically, only big leaguers Abner Dalrymple, Nap Lajoie, Mel Ott, Bill Nicholson (baseball), Bill Nicholson, Barry Bonds, Josh Hamilton, and Corey Seager hold the distinction of being intentionally walked with the bases loaded.

:When a home run is hit with the bases loaded, it is called a grand slam (baseball), grand slam. It scores four runs, which is the most runs that can be scored on a single play.

basement

:Last place, bottom of the standings. Also Glossary of baseball (C)#cellar, cellar.

bat

:*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 Glossary of baseball (B)#bat the ball, bat the ball.
:*A player known as a good hitter might be said to have a good bat. Headline: "Shortstop mixes golden glove with solid bat." A player who is adept at both hitting and fielding might be said to have a good bat and good glove. The headline "Wesleyan shortstop Winn has bat and glove" does not mean Winn owns a bat and a glove, it means he is very skilled at both hitting and fielding.
:*A team with many good hitters might be said to have a lot of "bats" (referring to the players not the instrument). "It's an awesome thing when we all get going like that," David Murphy (baseball), Murphy said. "We've got so many bats in our lineup that we're hard to beat if we keep hitting."

bat around

:According to ''The Dickson Baseball Dictionary'', a team has "batted around" when each of the nine batters in the team's Batting order (baseball), lineup has made a Glossary of baseball (P)#plate appearance, plate appearance, and the first batter is coming up again during a single inning. Dictionary.com, however, defines "bat around" as "to have every player in the lineup take a turn at bat during a single inning". It is not an official statistic. Opinions differ as to whether nine batters must get an at-bat, or if the opening batter must bat again for "batting around" to have occurred.

bat drop

:A physical property of a bat, expressed as a (usually) negative number equal to the bat's weight in ounces minus its length in inches. For example, a bat that is long and weighs has a bat drop of –3. In general, bats with a larger bat drop (i.e., lighter) are easier to swing, and bats with a smaller bat drop (i.e., heavier) can produce faster ball velocity, though these results depend on the batter's ability.

bat flip

:A celebration in which a batter who just hit a home run flips/tosses the bat in a dramatic way, rather than simply dropping it as they start running. The practice is controversial - some players such as Tim Anderson (baseball), Tim Anderson and Jose Bautista have been subject to retaliation by the opposing team when they bat flipped after a home run against them.

bat the ball

:To hit the ball with the batwhether into fair territory, fair territory or foul ball, foul.

batter

batter's eye

:A solid-colored, usually dark area beyond the Center fielder, center field wall that is the visual backdrop for the Glossary of baseball (B)#batter, 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 the Yankee Stadium (1923), first Yankee Stadium. At one time there were seats in that section, but because of distractions the seats were removed and the area was painted black.

batter's box

:A rectangle on either side of Glossary of baseball (H)#home plate, home plate in which the Glossary of baseball (B)#batter, batter must be standing for fair play to resume. A foot and a hand out of the box are not sufficient to stop play (although pitchers will usually respect a batter's wish to step out of the box). The umpire must grant the batter a timeout before play is stopped.

battery

:The Glossary of baseball (P)#pitcher, pitcher and Glossary of baseball (C)#catcher's interference, catcher considered as a single unit, who may also be called batterymen or batterymates of one another. The use of this word was first coined by Henry Chadwick (writer), Henry Chadwick in the 1860s in reference to the firepower of a team's pitching staff and inspired by the Artillery battery, artillery batteries then in use in the American Civil War. Later, the term evolved to indicate the combined effectiveness of pitcher and catcher.

battery mates

:A Glossary of baseball (P)#pitcher, pitcher and Glossary of baseball (C)#catcher's interference, catcher from the same team. See "battery".

batting average

:Batting average (BA) is the average number of Glossary of baseball (H)#hit, hits per Glossary of baseball (A)#at bat, 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 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. Bases on balls are not counted in calculating batting average. This is part of the reason Glossary of baseball (O)#on-base percentage (OBP), OBP is now regarded by "Glossary of baseball (F)#figger filbert, 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 as 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 Cap 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 refers to a period within a game when one team's hitters have so totally dominated a given Glossary of baseball (P)#pitcher, pitcher that the game resembles a batting practice session.

bean

:A Glossary of baseball (P)#pitch, pitch intentionally thrown to Glossary of baseball (H)#HBP, hit the Glossary of baseball (B)#batter, 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: "Mike Piazza, Piazza says Roger Clemens, Clemens Purposely Beaned Him."

beat out

:When a runner gets to first base before the throw, he beats the throw or beats it out. Akin to Glossary of baseball (L)#leg out, 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."

beat the rap

:Occurs when a batter hits the ball on the ground with a runner on first and fewer than two outs. If the play has the potential of being a double play, the batter can beat the rap if he reaches first base before the throw from the fielder who recorded the putout at second base. The result of the play becomes a fielder's choice.

behind in the count

:Opposite of Glossary of baseball (A)#ahead in the count, 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. "While he allowed only three hits, he walked five and pitched from behind in the count."

:*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 actual belt worn by a player as part of the uniform, usually mentioned in reference to the location of a pitch or a ball in play.

bench jockey

:A player, coach or manager with the talent of annoying and distracting opposition players and Glossary of baseball (U)#umpire, umpires from his team's dugout with verbal repartee. Especially useful against those with Glossary of baseball (R)#rabbit ears, rabbit ears. The verbal jousting is frequently called "riding"; hence the "rider" from the dugout becomes a "bench jockey". Riding opposition players enough to unnerve them but not enough to enrage them and provoke a fight is believed to be fast-fading in the 21st-century game. Major League Baseball players on the injured list are permitted to be on the bench but they are not permitted to engage in bench jockeying.

bender

:A Glossary of baseball (C)#curveball, 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 Medwick, Joe 'Ducky' Medwick of the St. Louis Cardinals said he was 'swinging at aspirins'."

big fly

:A Glossary of baseball (H)#home run, home run.

big inning

bleachers

: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.

If the pitcher further allows the winning run to score, he is charged with both a loss and a blown save. If, after blowing the save, the pitcher's team regains the lead, the pitcher may also be credited with the win. The blown save is not an officially recognized statistic by Major League Baseball, but is recognised by the Rolaids Relief Man Award, which charges two points against a reliever's record for a blown save opportunity. It is often used on broadcasts to characterize the "record" of Glossary of baseball (C)#closer, closers analogous to win–loss records of starters. "Jones has made 31 out of 34 saves" or "Jones has 31 saves and three blown saves."

box

:*The vicinity of the Glossary of baseball (M)#mound, 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.

Bugs Bunny change-up

:A change-up pitch that appears to arrive at homeplate so slowly that a batter can make three swings and misses on a single pitch. Whiff-whiff-whiff, three strikes and the batter is out. The reference is to Bugs Bunny, the animated cartoon character, who is depicted employing such a pitch in the cartoon ''Baseball Bugs''. As Trevor Hoffman's changeup evolved into an all-world weapon, his pitching teammates were in awe of it, much like many hitters were. They liked it so much, they gave it a nickname.
