ABSTRACT:
Games practice device having two upright spaced poles and an elastic line formed in three sections extending from a common junction. Ends of two sections are formed into loops engaged around cylindrical surfaces of end connectors which provide couplings to the upper ends of the poles. A ball is suspended from the third line section. The line sections are formed from a single length of elastic material, knotted to form the three line sections. The poles have apertured outward peripheral flanges at the lower ends so that hooked stays can be engaged at one end in the apertures and can be pressed at the other ends into a ground surface to hold the poles upright.
