UNIVERSITY PLACE, Washington, June 21 (Reuters) - Blessed with a game fit to match his winning personality, American young gun Jordan Spieth's meteoric rise to the upper echelons of the golf world continued with a second successive major victory at the U.S. Open on Sunday.
Aged just 21, Masters champion Spieth arrived at Chambers Bay at the start of the week with his sights set on a possible calendar grand slam of all four majors and he now leaves the Pacific Northwest halfway towards that unique target.
"It's incredible to win a major championship," Texan Spieth told reporters after benefiting from a final hole three-putt by fellow American Dustin Johnson to triumph by one shot.
