摘要： A shaft having an upper end; a first horizontal arm fixedly attached to the upper end of the shaft and a second, semi-rigid, flexible side arm fixedly attached to the first horizontal arm such that the second semi-rigid, flexible side arm bendably extends beyond the terminating end of the first horizontal arm, with a slightly downward slope; and means for releasably attaching to the side of a tennis ball provided on the second, semi-rigid, flexible side arm, such that when the tennis ball is attached to the second semi-rigid, flexible side arm, its slightly downward slope and slight curve provides a visual perception that the tennis ball is traveling on its way down to the trainee, while simultaneously being held in a manner which allows the trainee's racquet to travel up on, through and over the tennis ball, thereby repeatedly and consistently placing the tennis ball within the racquet's sweet-spot, without impeding the trainee's stroke.
