Jump ball


Jump ball
The jump ball that starts the game, known as the opening tip, takes place at center court.

A jump ball is a method used to begin or resume play in basketball. It is similar to a face-off in ice hockey or ball-up in Australian rules football. Two opposing players attempt to gain control of the ball after it is tossed up into the air in between them by an official.

In the NBA, a jump ball occurs at the start of the game (called the opening tip), the start of any extra period, 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 (entire game) and the UAAP (in the final two minutes of a game and overtime in UAAP only) 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, the team whose basket that the possession arrow is currently pointing to gets the ball. 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.

The alternating possession arrow rule went into effect in college basketball in 1981. Ever since, it has been controversial. Supporters of the possession arrow believe that jump balls give the team with taller players and better leapers an unfair advantage over the other, plus the possession arrow (especially in the NCAA Tournament) gives another element of strategy. But those who oppose the possession arrow believe that it has frequently undone a trailing team's defensive effort because it is the other team's turn to get the ball.

The International Basketball Federation, 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 the Union of European Basketball Leagues (ULEB), the conductor of the Euroleague and ULEB Cup, adopt the FIBA rule in 2005 as part of FIBA sanctioning the Euroleague effective the 2005-06 season. Previously, the ULEB used the NBA jump ball rules.
