Spieth, the world number two, started the final round in a four-way tie for the lead with Johnson, Branden Grace and Jason Day of Australia on four under.

He bogeyed his opening hole to drop back to three under but 12 pars and two birdies followed to keep the Texan in touch before a three-shot swing on the 16th put him three clear with two to play.

Spieth and playing partner Grace were both five under but the South African, who had played solidly for 15 holes with two birdies and a bogey, hit his tee shot 50 yards right and out of bounds.

That led to a double-bogey six and he dropped to three under, while Spieth drained a 28-foot birdie putt to move to six under.

Johnson, playing in the final group with Day, led by two at one stage after a couple of birdies in a bogey-free opening nine holes.

He looked to have cracked on the back nine, though, with three bogeys in four holes dropping him back to three under after 13.

However, Spieth and Johnson were level after the par-three 17th. Spieth found trouble with his tee shot and double-bogeyed while Johnson hit the green and holed his birdie putt.

Both players missed eagle putts on the last but after Spieth kept his nerve to hole his fourth shot, Johnson pushed his attempt wide.
