A jump ball is a method used to begin or resume play in basketball. It is similar to a face-off in ice hockey and field lacrosse and a ball-up in Australian rules football. Two opposing players attempt to gain control of the ball after an official tosses it into the air between them.
Originally, jump balls were used to restart play at the beginning of every quarter and after each basket scored. The NBA and NCAA dropped jump balls after baskets in the mid-20th century. The NBA stopped using jump balls for 2nd-4th quarter possession in 1975, and the NCAA implemented alternating possession rules in 1981 that award possession sequentially for all jump ball situations after the opening tip at the beginning of the game. The WNBA and Euroleague Basketball have adopted the NBA's jump ball rules, while other leagues have implemented alternating possession. 3x3 basketball does not use jump balls at all.
The rules for jump balls are relatively relaxed, with penalties rarely called on players touching the ball before it has reached the peak of its throw. Jump ball throw styles vary, and may feature misdirection to catch players off guard.
In the NBA, WNBA, and competitions operated by Euroleague Basketball, a jump ball occurs at the start of the game (called the opening tip or opening tip-off), the start of any extra period (tip-off), to settle special situations where penalties cancel out and neither team is previously entitled to the ball, and to settle any held balls. Held balls occur when two opposing players both lay equal claim to the ball, and after trying to wrestle it from each other, end up in a stalemate. A jump ball may also be called if there are different calls by two or more referees.
However, most competitions other than the NBA, WNBA, and Euroleague Basketball use the alternating possession rule to settle all jump ball situations after the opening tip. This uses a possession arrow on the scorekeeper's table. Whenever such a jump ball situation occurs, possession of the ball is awarded to the team that is moving in the direction of the possession arrow on offense. The arrow then swaps to point to the other team. At the start of the game, the arrow points to the team that lost the opening tip.
James Naismith's original rules for basketball included a jump ball to begin every quarter, and after every basket scored. The NCAA first changed these rules in 1937, awarding possession after baskets to the scored-upon team. The NBA mirrored the NCAA's jump ball rules in 1949, and add a further change in 1975, removing jump balls to begin the second, third and fourth quarters, automatically granting possession in the second and third quarters to the team losing the opening tip, and possession in the fourth to the team that won the first tip. [1]
The alternating possession arrow rule went into effect in college basketball in 1981. League executives adopted the rule based on the belief that referees were not able to consistently ensure fair tosses, citing examples of games whose outcomes were effectively sealed by an inadequate toss. The decision has been controversial. Advocates of alternating possession argue that it is more fair, but this is disputed by its opponents, who also argue that jump balls are a vital part of the sport. [1]
FIBA, with recommendation by NCAA Men's Supervisor of Officials Hank Nichols, on the FIBA World Technical Commission at the time, adopted the alternating possession rule in 2003, with a major difference. In overtime periods, play begins with the arrow. In other organizations, another jump ball is conducted.
FIBA mandated that ULEB, which operated the EuroLeague and Eurocup before handing responsibility to the Euroleague Company, adopt the FIBA rule in 2005, as part of FIBA's rules being used by the EuroLeague, effective the 2005-06 season. Previously, the EuroLeague used the NBA jump ball rules. However, the Euroleague Company reinstated the jump ball rule in 2013.
Uniquely, 3x3, a formalized version of halfcourt three-on-three basketball overseen by FIBA, does not use a jump ball at any time in a game. Under current (2016) rules, the first possession is based on the result of a pregame coin toss; the winner can choose to have the first possession either at the start of the game or at the start of a potential overtime. During the game, held balls are automatically awarded to the defensive team. [2]
Jump balls are a relatively unregulated part of basketball. In the NBA, players are technically supposed to touch the ball only after it has reached the top of its flight arc, but slight breaking of this rule––known as "stealing the toss"––is commonplace, tolerated, and arguably expected of players. There are no league-wide standards regulating how referees are to throw the ball beyond the stipulation that the ball should reach its top altitude squarely between the two players competing for it. In order to curb stealing, referees incorporate misdirection into their throwing styles to catch players off guard and unable to preempt the toss. Consequently, while height is obviously helpful for players competing for jump balls, top jump ball scorers are primarily credited for their agility and ability to time both the throw and their opponent. [1]
The leniency in penalizing jump ball stealing is in part due to its position in the game: referees are reluctant to stop play immediately after it starts, and quarter-opening jump balls lend minimal advantage because the losing team will be granted possession in the following quarter. An NBA study on jump balls found that in the 2022-2023 season, only 0.3% of jump balls had violations called. [1]
Jump ball throwing styles are varied, including one-handed, two-handed, underhanded, and overhanded styles. While the ball's trajectory is typically delivered at a near vertical angle, this is not required. Ken Mauer is particularly noted for his unusual, off-center throwing style, described as "[taking] multiple steps back, then toss[ing the ball] at an angle with a surprise motion that almost made him look like a volleyball player setting the ball for a teammate". More generally, throw styles that incorporate stepping away from the ball's destination, known as "pulling", are employed by referees as a way to mitigate the risk of being injured by players competing for the toss. [1]
Basketball is a team sport in which two teams, most commonly of five players each, opposing one another on a rectangular court, compete with the primary objective of shooting a basketball through the defender's hoop, while preventing the opposing team from shooting through their own hoop. A field goal is worth two points, unless made from behind the three-point line, when it is worth three. After a foul, timed play stops and the player fouled or designated to shoot a technical foul is given one, two or three one-point free throws. The team with the most points at the end of the game wins, but if regulation play expires with the score tied, an additional period of play (overtime) is mandated.
In basketball, the basketball court is the playing surface, consisting of a rectangular floor, with baskets at each end. Indoor basketball courts are almost always made of polished wood, usually maple, with 3.048 meters (10 ft)-high rims on each basket. Outdoor surfaces are generally made from standard paving materials such as concrete or asphalt. International competitions may use glass basketball courts.
In basketball, a technical foul is any infraction of the rules penalized as a foul which does not involve physical contact during the course of play between opposing players on the court, or is a foul by a non-player. The most common technical foul is for unsportsmanlike conduct. Technical fouls can be assessed against players, bench personnel, the entire team, or even the crowd. These fouls, and their penalties, are more serious than a personal foul, but not necessarily as serious as a flagrant foul.
A shot clock is a countdown timer used in a variety of games and sports, proving a set amount of time that a team may possess the object of play before attempting to score a goal. Shot clocks are used in several sports including basketball, water polo, lacrosse, poker, ringette, korfball, tennis, ten-pin bowling, and various cue sports. It is analogous with the play clock used in American and Canadian football, and the pitch clock used in baseball. This article deals chiefly with the shot clock used in basketball.
In basketball, free throws or foul shots are unopposed attempts to score points by shooting from behind the free-throw line, a line situated at the end of the restricted area. Free throws are generally awarded after a foul on the shooter by the opposing team, analogous to penalty shots in other team sports. Free throws are also awarded in other situations, including technical fouls, and when the fouling team has entered the bonus/penalty situation. Also, depending on the situation, a player may be awarded between one and three free throws. Each successful free throw is worth one point.
In basketball, a personal foul is a breach of the rules that concerns illegal personal contact with an opponent. It is the most common type of foul in basketball. A player fouls out on reaching a limit on personal fouls for the game and is disqualified from participation in the remainder of the game.
The rules of basketball are the rules and regulations that govern the play, officiating, equipment and procedures of basketball. While many of the basic rules are uniform throughout the world, variations do exist. Most leagues or governing bodies in North America, the most important of which are the National Basketball Association and NCAA, formulate their own rules. In addition, the Technical Commission of the International Basketball Federation (FIBA) determines rules for international play; most leagues outside North America use the complete FIBA ruleset.
A three-point field goal is a field goal in a basketball game made from beyond the three-point line, a designated arc surrounding the basket. A successful attempt is worth three points, in contrast to the two points awarded for field goals made within the three-point line and the one point for each made free throw.
In basketball, a flagrant foul is a personal foul that involves excessive or violent contact that could injure the fouled player. A flagrant foul may be unintentional or purposeful; the latter type is also called an "intentional foul" in the National Basketball Association (NBA). However, not all intentional fouls are flagrant fouls, as it is an accepted strategy to intentionally commit a foul in order to regain possession of the ball while minimizing how much time elapses on the game clock.
This glossary of basketball terms is a list of definitions of terms used in the game of basketball. Like any other major sport, basketball features its own extensive vocabulary of unique words and phrases used by players, coaches, sports journalists, commentators, and fans.
In basketball, a foul is an infraction of the rules more serious than a violation. Most fouls occur as a result of illegal personal contact with an opponent and/or unsportsmanlike behavior. Fouls can result in one or more of the following penalties:
A basketball is a spherical ball used in basketball games. Basketballs usually range in size from very small promotional items that are only a few inches in diameter to extra large balls nearly 2 feet (60 cm) in diameter used in training exercises. For example, a youth basketball could be 27 inches (69 cm) in circumference, while a National Collegiate Athletic Association (NCAA) men's ball would be a maximum of 30 inches (76 cm) and an NCAA women's ball would be a maximum of 29 inches (74 cm). The standard for a basketball in the National Basketball Association (NBA) is 29.5 inches (75 cm) in circumference and for the Women's National Basketball Association (WNBA), a maximum circumference of 28.5 inches (72 cm). High school and junior leagues normally use NCAA, NBA or WNBA sized balls.
The Trent Tucker Rule is a basketball rule that disallows any regular shot to be taken on the court if the ball is put into play with under 0.3 seconds left in game or shot clock. The rule was adopted in the 1990–91 NBA season and named after New York Knicks player Trent Tucker, and officially adopted in FIBA play starting in 2010. When the WNBA was established in 1997, this rule was adopted too.
In basketball, a field goal is a basket scored on any shot or tap other than a free throw, worth two or three points depending on the location of the attempt on the basket. Uncommonly, a field goal can be worth other values such as one point in FIBA 3x3 basketball competitions or four points in the BIG3 basketball league. "Field goal" is the official terminology used by the National Basketball Association (NBA) in their rule book, in their box scores and statistics, and in referees' rulings. The same term is also the official wording used by the National Collegiate Athletic Association (NCAA) and high school basketball.
The key, officially referred to as the free throw lane by the National Basketball Association (NBA), the National Collegiate Athletic Association (NCAA), the National Association of Intercollegiate Athletics (NAIA), and the National Federation of State High School Associations (NFHS), and the restricted area by the International Basketball Federation (FIBA), is a marked area on a basketball court surrounding the basket, where much of the game's action takes place.
In basketball, an official enforces the rules and maintains order in the game. The title of official also applies to the scorers and timekeepers, as well as other personnel that have an active task in maintaining the game. Basketball is regarded as among the most difficult sports to officiate due to the speed of play, complexity of rules, the case-specific interpretations of rules, and the instantaneous decision required.
In the sport of basketball, the bonus situation occurs when one team accumulates a requisite number of fouls, the number of which varies depending on the level of play. When one team has committed the requisite number of fouls, each subsequent foul results in the opposing team's taking free throws regardless of the type of foul committed. Teams under the limit are commonly referred to as having fouls to give, and thus they can try to disrupt their opponents without being penalized free throws. These fouls reset every quarter or half depending on the rules in use.
Basketball is a ball game and team sport in which two teams of five players try to score points by throwing or "shooting" a ball through the top of a basketball hoop while following a set of rules. Since being developed by James Naismith as a non-contact game that almost anyone can play, basketball has undergone many different rule variations, eventually evolving into the NBA-style game known today. Basketball is one of the most popular and widely viewed sports in the world.
3x3 basketball is a variation of basketball played three-a-side, with one backboard and in a half-court setup. According to an ESSEC Business School study commissioned by the International Olympic Committee, 3x3 is the largest urban team sport in the world. This basketball game format is currently being promoted and structured by FIBA, the sport's governing body. Its primary competition is an annual FIBA 3X3 World Tour, comprising a series of Masters and one Final tournament, and awarding six-figure prize money in US dollars. The FIBA 3x3 World Cups for men and women are the highest tournaments for national 3x3 teams. The 3x3 format has been adopted for both the 2020 Summer Olympics and 2022 Commonwealth Games.
Big3 is a 3-on-3 basketball league founded by hip-hop musician and actor Ice Cube and entertainment executive Jeff Kwatinetz. The league consists of 12 teams whose rosters include both former NBA players and international players. The rules of Big3 games contain deviations from the official rules of 3-on-3 basketball as administered by FIBA. In January 2020, Big3 announced its rule set would be the core of a new basketball variant called "Fireball3".
