Rising American talent Jordan Spieth upstaged Rory McIlroy and Adam Scott with a four-under-par 67 to take a one-stroke lead after the first round of the Australian Open on Thursday.
The 21-year-old Texan stormed to the top of the leaderboard with a birdie blitz on the back nine and made it clear he had not come to Australia to be a spectator at a duel between the number one and number three players in the world.
Defending champion McIlroy battled jet lag and tricky early conditions to emerge with a 69 for a share of fourth, while world number three Scott finished seven shots off the pace following an untidy round of 74.
Spieth, playing with Scott, started with a birdies at the first and fifth before stalling with a bogey at the sixth but it was not until the turn that he really hit his stride.
He picked up a shot at the 10th and then eased clear of the field with three birdies in a row from the 14th before falling back towards the pack with a second bogey at the 17th.
Sliding a four-foot birdie putt inches past the hole on the 18th meant he had to be satisfied with just the one stroke edge over Australians Aron Price and Scott Gardiner, who both shot 68s.
Last year, McIlroy also shot a 69 in the opening round at the par-72 Royal Sydney as Scott soared into the lead with a 10-under-par course record.
It was apparent that the Australian was not going to have a similar day on Thursday when he double-bogeyed the first and overcooked a putt to drop another shot at the third.
