moving the ball from one hand to the other while dribbling

A crossover dribble is a basketball maneuver in which a player dribbling the ball, typically a point guard, switches the ball rapidly from one hand to the other. In a typical example the player heads upcourt, dribbling the ball in (say) the left hand, then makes a wide step left with a good head fake. If the defender is deceived, the player can then switch to dribbling with the right hand and pass the defender.
