Man in form – American Jordan Spieth lifts the U.S. Open trophy to add to the Masters crown he won earlier this year. He begins The Open looking to take a place in golfing history.
Spieth showed typical determination to edge ahead of the leading pack on the final day to claim back-to-back majors.
Dustin Johnson will be left to rue his three-putt on the final hole which cost him a chance of a first major.
Former British Open champion Louis Oosthuizen ripped through the back nine in 29 shots for a 67 and four-under aggregate of 276 to tie for second with Johnson.
Joint overnight leader Branden Grace was mounting a strong challenge to Spieth before a double bogey on the 16th.

World number one Rory McIlroy launched a last day charge at Chambers Bay with a string of final round birdies in a 66 for level par.

Tiger Woods endured a nightmare start to the tournament with a 10-over 80, his worst round at a U.S. Open.

Masters winner Spieth stepped up his bid for a second straight major with a fine second round to move into a share of the lead at halfway on five-under and he was always a factor.
