Abstract: This invention comprises a ball-capturing tennis net assembly designed to be used in combination with existing court structures for catching balls which strike the standard tennis net. The catch-net extends under or is attached to the bottom of the standard tennis net forming two sides. Each side protrudes upwards at an angle near 45 degrees and is held in place by brackets. At least one end bracket is mounted to each of the standard net posts and functions to hold the top of the two sides of the catch-net parallel to and at a desired width from the standard tennis net. The end brackets hold the bottom of the catch net tightly around the bottom of the standard tennis net. At least two middle brackets, which when assembled form a center spacer unit, are located between the two net posts to help hold the catch-net open in a v-shaped position under and onto each side of the court divided by the standard tennis net. The catch-net is also designed to receive and hold the middle brackets in position.
