Golf: Jordan Spieth lights up US Masters, as Rory McIlroy and Tiger Woods struggle

AUGUSTA, UNITED STATES (AFP) - Jordan Spieth produced one of the greatest rounds of golf in major history on Thursday with a 64 to lead by three strokes after the first round of the 79th US Masters.

The 21-year-old Texan at one stage looked in line to become the first player to shoot below 63 in a major - a mark shared by 24 golfers - but a poor approach shot to the 15th led to his only bogey and nudged the record agonisingly out of his grasp.

Still, Spieth closed with a ninth birdie at the last hole to surpass fellow young gun Rory McIlroy as the youngest player to have led the Masters after the opening round and underlined once again his huge potential.

Tied for second on his debut last year, Spieth ended the day at Augusta National as sole leader, three shots clear of a rejuvenated South African veteran Ernie Els, England's Justin Rose, Australian Jason Day and American Charley Hoffman.

"It's nice to put myself in a position now where I can really stay patient, dig in and keep giving myself opportunities and not worry about anything else," Spieth said. "I can pretty much control my own destiny from here. And pleased to be in that position here again.

"I was leading last year at one point by a couple of shots on Sunday, it didn't go my way. I know how many things can happen in a major championship and I try and learn from last year, and stay patient these next three rounds."

The superb performance by the young Texan eclipsed the two big storylines that were the talk of Augusta at the start of the day concerning Tiger Woods and Rory McIlroy.

The 39-year-old Woods returned after two-month timeout he called on himself to try and piece back together his once dominant game. But he struggled at times early on, as he clattered a couple of drives into the trees and then found the water of Rae's Creek at the 13th en route to a 73.

While it was a step forward for him in some ways after his woeful performances earlier this year, but it still leaves him with a fight on his hands just to make the Masters cut, something he last failed to do in 1996 when he was still an amateur.

Woods was, however, upbeat over his showing, saying that the unusually soft Augusta greens had been his main problem.

"I felt good. I felt like I hit the ball well enough to shoot three-under par," he said. "Our entire group was really struggling at the greens. We were talking about how slow they were today. We had a hard time hitting the putts hard enough."

World No. 1 McIlroy, aiming to become just the sixth man in golfing history to complete a career Grand Slam of the four majors, settled for a quiet day. His one-under 71, which contained three birdies and two bogeys, was largely without incident and he would have been even more handily placed if not for Spieth's late fireworks.

"I just kept telling myself to be patient out there today. It was a tricky day. The wind was swirling a little bit. Pin positions were tough. Anything under par I felt was a pretty good score," the 25-year-old said. "It was nice to pick up a couple birdies on the back nine, on the par-fives there. Pretty satisfied with today's work."

Defending champion Bubba Watson was solid en route to a 71 - the same as McIlroy and namesake Tom Watson, who at 65 became the oldest player in Masters history to break par. Three-time winner Phil Mickelson was well-placed on 70, while 2012 winner Adam Scott settled for a level par 72.
