is a two-point shot attempt made by leaping from below, laying the ball up near the basket, and using one hand to bounce it off the backboard and into the basket. The motion and one-handed reach distinguish it from a jump shot. The layup is considered the most basic shot in basketball. When doing a layup, the player lifts the outside foot, or the foot away from the basket.
