Jordan Spieth wins US Open title

Jordan Spieth is halfway towards an unprecedented calendar grand slam after winning his second major in succession with a thrilling victory in the 115th US Open.

After three-putting the opening hole, Spieth recovered with birdies at the eighth, 12th and 16th, where playing partner Branden Grace drove out of bounds to card a double bogey and drop out of the lead.

That gave Masters champion Spieth a three-shot lead - only for the 21-year-old to double bogey the 17th, hitting a wild tee shot and then compounding the error by three-putting from 40 feet.

In the group behind Dustin Johnson, who had been two clear on the front nine, then made birdie on the 17th to get into a tie for the lead, only for Spieth to hit two brilliant shots onto the 18th green to set up a two-putt birdie and finish five under.

With the pressure back on Johnson the 30-year-old responded superbly, producing an even better approach than Spieth - but he three-putted from 12 feet to squander another chance at a first major title.

South Africa's Louis Oosthuizen also finished on four under after recovering from three bogeys in the first four holes with six birdies in his last seven for a back nine of 29 and closing 67.
