A ball returning device comprising a frame and a net disposed within the frame, wherein the horizonal members of the frame are nonlinear so that the attached net is in two sections having a nonlinear angle therebetween. In an alternate embodiment of the present invention, the net is connected to three upstanding members in a nonlinear alignment so that two sections are formed in the net. The adjacent, nonlinear sections in the net improve the practice quality of the user for such games as tennis.
