By Tony Jimenez TROON, Scotland (Reuters) - Double major winner Jordan Spieth had a brief moment cradling the coveted Claret Jug 12 months ago and is longing to make his mantelpiece a permanent home for the trophy handed to the British Open champion. A maiden victory in golf's oldest major this week would also send the 22-year-old one step closer to achieving a career grand slam. "This is a very special tournament," Spieth told a news conference on Tuesday.
