发明名称 Tennis ball retriever
摘要 A spring wire loop is affixed to a tennis racquet to enable a player to conveniently scoop a tennis ball off the playing surface and retrieve it. In one add-on embodiment, the loop can be affixed by mounts secured to the strings of an existing racquet; in another it is held in place by the racquet's bumper guard; in a further alternative, the loop can be secured to mounts built into the racquet at manufacture.
