Inbasketball, aturnover occurs when a team loses possession of the ball to the opposing team before a player takes a shot at their team's basket. This can result from a player getting the ballstolen, steppingout of bounds, having a pass intercepted, committing aviolation (such asdouble dribble,traveling,shot clock violation,three-second violation orfive-second violation), or committing anoffensive foul (includingpersonal,flagrant, andtechnical fouls).
Turnovers can be classified into two categories:dead-ball turnovers and live-ball turnovers. Dead-ball turnovers are those which result in dead balls (e.g. rules violations) and live-ball turnovers are those which do not require play to be stopped (e.g. an intercepted pass or recovered loose ball).[1]
According toBoston Globe sportswriterBob Ryan, the concept of the turnover was first formulated by his colleague Jack Barry.[2] Turnovers were first officially recorded in theAmerican Basketball Association (ABA) during the1967–68 season. TheNBA began tracking team turnovers during the1973-74 season and started tracking turnovers for individual players during the1977–78 season subsequent to theNBA-ABA merger. TheWNBA has recorded turnovers since its inaugural season in 1997.
