I claim the ornamental design for a telescoping golf ball retriever, as shown and described.
FIG. 1 is a side elevational view showing my new design, all sides being the same. The broken lines representative of surface details are shown for illustrative purposes only and form no part of the claimed design.
FIG. 2 is a plan view of the distal end thereof. The broken lines within the perimeter are included for the purpose of illustrating a portion of the telescoping ball retriever that forms no part of the claimed design;
FIG. 3 is a plan view of the proximal end thereof; and,
FIG. 4 is an isolated enlarged side view of the distal end of said retriever with a retrieved golf ball drawn in phantom.
