Upright golf net assembly

An upright golf net assembly for practicing a golf swing has a stored mode collapsible for storage and a deployed mode expandable for practice and includes a pair of interconnected frames. The first and second frames are arranged in a substantially vertical upright position when the assembly is in the deployed mode, each frame having opposite lateral sides and an upper and lower portion. The first and second frames form perimeters that are interconnected at each of their respective opposite lateral sides, such that the first and second frames intersect at their respective opposite lateral sides. The first and second frames are retained in cooperating relation one to the other such that the first and second frames mutually support one another. A netting assembly is attached to the first frame and creates a substantially vertical netting surface for engaging the ball when the assembly is in the deployed mode.
