What’s a Jump Ball: Definition of the Term
A jump ball is a method used to start or resume play in a basketball game. It involves tossing the ball between two players from opposing teams who attempt to gain possession by tapping it to a teammate after it reaches its peak height.
Additionally, a jump ball may be called when two opposing players both have possession of the ball simultaneously.
Jump balls in the National Basketball Association (NBA) serve as a means to determine possession when two players simultaneously possess the ball or when the referees cannot determine which team has possession.
This feature is unique to the NBA, as other basketball leagues such as FIBA, NCAA, and high school basketball employ alternating possessions when calls of a held ball (jump ball) occur. If two players gain control of the ball using both hands, the referee blows the whistle and calls a jump ball.
During a game, a jump ball is conducted similarly to the start of the game, but it can occur at various locations on the court. Depending on where the jump ball is called, it can occur at midcourt or between the two circles connected to the free throw line.

Quick Facts About Jump Balls:
- The practice of starting a basketball game with a jump ball can be traced back to the very first recorded game in 1891. Since 1938, jump balls have also been used to determine possession in situations where there is a tie-up or dispute over possession.
- In the NBA, when two opponents simultaneously gain control of the ball, it results in a jump ball situation. When this occurs, the referee retrieves the ball and instructs the two players involved to line up at the top of the key while the other players position themselves around them.
- During a jump ball, the official tosses the ball between the two players, and both players attempt to tip it to their respective teams. The player who successfully gains possession of the ball following the jump ball is awarded possession, and the game continues without interruption.
- The alternating possession rule is employed by FIBA and the NCAA. Under this rule, a special possession arrow governs both teams, initially pointing toward the team that lost the opening tip.
- The concept of a possession arrow was introduced in 1981. The introduction of the possession arrow brought about a new strategic element to basketball games, ensuring that both teams had equal opportunities for possession without relying solely on height.
- In 2003, FIBA followed the NCAA’s recommendation and adopted the possession arrow rule. FIBA introduced an additional stipulation specific to overtime situations. When a game goes into overtime, the team that possesses the arrow is granted initial possession of the ball.
Unlocking The Jump Ball Process

The jump ball process in basketball involves two players from opposing teams trying to gain possession of the ball after an official tosses it up into the air between them. This can determine which team gets possession and can be called at different times during a game.
During a jump ball, the other players on the floor must stand at the side of a 6-foot area surrounding the circle, and they can only move once the ball is touched by one of the jumpers.
Jump balls can happen at the beginning of each game, at the beginning of each overtime period, and at any other time when officials signal for a jump ball. Why is this method for putting the ball into play so important that it must be included in basketball rules?
Role in Starting and Resuming Games
A jump ball is vital to the start of a game because it gives both teams an equal opportunity to get an early lead.
Jump balls also come into play when two players have simultaneous possession or officials cannot determine who should get possession. In these cases, officials may signal for a jump ball, giving both teams equal chances to gain control of the basketball.
Circumstances Leading to a Jump Ball
Other circumstances may result in a jump ball. If two or more opposing players have an equal hold on the ball, officials signal for a jump ball to break possession and decide which team will control it moving forward.
Furthermore, if an offensive player illegally dribbles the basketball and their hand comes in contact with an opponent’s hand, creating a held-ball situation, another jump ball will be called.
Another instance of a jump ball arises when a blocked shot falls back into the play’s top rather than going out of bounds. This often brings together players from both teams attempting to seize control of the rebound.
Jump balls aren’t just reserved for starting games; they occasionally occur during gameplay as an alternative to resetting the shot clock following some violation or out-of-bounds situations.
Essential Rules Governing Jump Balls
A few essential restrictions regulate who may participate in a jump ball scenario. The rules state that only one player from each team may be involved in the initial toss-up, and any others must remain outside the jumping circle until the ball is released.
Moreover, if a player jumps before the basketball is released or catches it instead of batting it out of the way, a jump ball violation will be called, leading to a turnover.
When following these regulations, players must take their starting position with at least one foot inside the jumping circle bounds circling the center line. Once that happens, officials throw the ball high into the air for two players to contest each other.
An additional crucial rule concerning jump balls is their placement. The jumping spot must be nearest to where play was stopped or became dead-ball. The officiating crew should use their knowledge of game precedents to ensure all game-clock records are accurate before initiating the tip-off.
Key Regulations and Violations
Jump balls are subject to strict regulations that govern the players’ actions while ensuring fair play. For example, before the referee tosses the ball up between two players, each player must have at least one foot inside or touching half of the circle.
Additionally, a jump ball is only considered in play once it reaches its peak height, meaning no player can touch it until it begins descending.
Several jump ball violations can result in a turnover or penalty for a team. One such violation occurs when a player jumps prematurely before the official releases the basketball.
An “illegal hold” violation happens if players from opposing teams incorrectly try to hold onto the ball instead of tapping it toward their teammates.
Moreover, if a player catches a jump ball as opposed to batting it off or touches the ball before it reaches its maximum height, they are committing another violation known as “catching.” Further still, standing within the center circle without direct involvement in the jump ball position results in another foul known as “tripping.”
The Impact of Jump Balls on Possession

The outcome of a jump ball has significant implications for which team gains possession and consequently dictates how the following plays out in-game. Winning possession offers teams an opportunity to enact their preferred offensive or defensive strategy, whereas not winning possession could result in a change of strategy or defense.
An excellent example of the importance of jump ball comes at the beginning of a game where one player from each team stands toe-to-toe at the half-court line inside the center circle facing the basket. Winning this is crucial as it establishes the first scoring opportunity and sets up early momentum for the game.
After every successful field goal, play resumes again, but the team that was scored on now has possession to start their offensive play. If a ball goes out of bounds, the clock stops, and possession is granted to the team that did not touch it last before going out.
With traditional rules, in case there’s shared possession after two opposing players secure hold of the basketball, officials signal for a jump ball to resolve any claims for control over the ball. However, college games have adopted alternate possession rules that grant alternating possessions to teams without needing to jump for control.
Overall, understanding how jump balls influence possession in basketball offers valuable insight into planning strategic moves and maintaining momentum during gameplay.

Alternating Possession Rule
Jump balls in basketball play a crucial role in determining possession. Winning the jump ball allows a team to make the first offensive play of the game or resume play after a held-ball situation. However, the traditional process of having players jump for the ball has been replaced with the alternating possession rule in many leagues, including NCAA college basketball.
In the alternating possession rule, instead of jumping for the ball, teams take turns possessing the ball based on a predetermined order in situations where a jump ball would have traditionally been used. The team that did not possess the ball during the previous held-ball scenario obtains possession at the next opportunity.
While some fans and players argue that this rule takes away from the excitement of the game, others feel that it simplifies things by reducing the number of jump balls to just those needed to begin games and overtime periods.
Strategies for Jump Ball Scenarios

One effective strategy when jumping for possession is for the center player to tap or deflect the ball toward their teammates instead of taking full possession themselves. This approach is particularly advantageous if several teammates are positioned nearby, as they can quickly gain control of the ball and launch an offensive play toward the net.
Some other tactics teams employ during jump balls include having specific players set up pick-and-rolls to free up shooters, setting screens near the basket to open up post opportunities, and using fast breaks to press home any advantage gained from winning the initial scramble.
Defensively, teams also have several critical strategies when facing jump balls. Many defenders try to position themselves slightly behind their opponent so that they can tap or deflect the ball without committing a foul.
Another approach is to lose the jump ball intentionally but immediately swarm around the other team’s playmaker, cutting off any potential passing or driving lanes. This prevents them from starting an offensive move immediately and gives your team time to organize defensively.
Offensive and Defensive Tactics
Jump balls can be crucial moments during a game since they can determine which team gains possession of the ball. One strategy for offensive and defensive tactics during jump ball scenarios is to study your opponent’s tendencies to gain an advantage.
Similarly, understanding your opponent’s tendencies by employing scouts could enable you to gain an advantage on defense. Scouts’ analyses should offer insights as to whether certain players typically attempt a quick pass after winning the jump ball or try to take it straight up themselves. If so, the defenders could use this knowledge to plan an effective response ahead of time.
Another important strategy on offense is communication and teamwork. Such collaboration could involve establishing set plays or having a specific plan for who will retrieve the tip versus which teammate trails behind for support. The offense also needs players to respond quickly without verbal direction since split-second decisions often happen in jump balls.
Defensively, players must work together effectively as well. Teamwork typically involves assigning responsibilities, such as one player boxing out an opposing team member while another anticipates where to go based on where the ball’s trajectory falls after a tip-off.
In conclusion, understanding and preparing for jump ball scenarios can significantly impact a team’s ability to win games. Observing an opponent’s tendencies on offense while effective communication and teamwork are essential for offense, while teamwork, boxing out, and anticipation lend themselves well defensively. Creating an effective strategy based on each player’s strengths is crucial.
Frequently Asked Questions and Explanations
1. In which leagues or levels of basketball is the jump ball rule enforced?
The jump ball rule is enforced in various leagues and levels of basketball, including professional, college, high school, and youth leagues.
According to the National Federation of State High School Associations (NFHS), the jump ball rule is required at the start of each game in high school basketball. In college and professional basketball, the rule applies when two players simultaneously control the ball or when officials cannot determine which team should gain possession.
2. Who typically participates in a jump ball, and what are their roles?
In a typical basketball game, the jump ball happens at the beginning of the game or after a tied-up situation where two opposing players have equal possession of the ball. The players who participate in a jump ball are usually the tallest and strongest players from both teams.
According to NBA statistics, centers have historically been the most common participants in jump balls, accounting for about 54% of all jump balls since the 2015-2016 season. Power forwards follow closely with 28% participation, while small forwards, shooting guards, and point guards combined account for only 18%.
3. Has the use of jump balls in basketball changed over time?
Jump balls have always been an integral part of basketball. However, over the years, there have been changes in how jump balls are used during games. For instance, in 2020, the NCAA changed its rules governing jump balls. Specifically, teams are now awarded the ball after the opening tip-off instead of conducting a jump ball. This change was made to reduce the number of unnecessary physical interactions between players early in the game.
Moreover, according to the official NBA rulebook, a jump ball is no longer used to start overtime periods. Instead, the team that won the initial tip-off gets possession of the ball at the beginning of overtime.
4. What circumstances lead to the referee calling a jump ball?
Jump balls are common in basketball, and they happen when two opposing players simultaneously gain possession of the ball. According to NBA rules, a jump ball is called when:
Two opposing players possess the ball simultaneously
The ball becomes lodged between the rim and the backboard or stanchion
A violation occurs that requires the ball to be put into play from the center circle (e.g., simultaneous out-of-bounds by both teams)
5. How often does a jump ball occur in a typical basketball game?
In a typical basketball game, jump balls occur less frequently than other violations or stoppages. According to the NBA rulebook, a jump ball is held at the beginning of each game, and after a held ball occurs during the game. In addition, jump balls can also be used to resolve certain situations concerning possession, although these instances are relatively rare.
For instance, in the 2020-2021 NBA season, there were an average of only 0.37 jump balls per game -a small fraction compared to the 61 fouls committed on average per game- according to Basketball-Reference.
Similarly, NCAA Division I men’s basketball during the 2019-2020 season had about 0.58 jump balls per game, according to NCAA’s official statistics.
Thus, while jump balls are an important part of basketball rules and strategies, they rarely occur in a typical game, and players must be prepared for them when they happen.
