It's too specific. I would focus on domains with a much broader appeal. Who would be your potential customer for that domain? There is likely only a few. Is that really the market you want to be in? It's hard enough to find a buyer in a huge market, let alone this small one. Not saying worthless, but keep in mind the size of your market when you buy names. If it means that much to you, make a golf game blog out of it for yourself.
