A vertical wall surface, providing a guide for a parallel putting stroke, is provided with an opening at the mid-point through which individual golf balls are to be ejected onto a putting surface prior to each stroke. A base, top, back and end walls enclose storage for a plurality of golf balls. A bar on the top of the device, which can be depressed by a putter, actuates a release mechanism to permit a single ball to pass through the opening in the vertical wall.
