Jump ball

A jump ball is a method used to begin or resume play in basketball. It is similar to a faceoff in ice hockey. 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.
