Super Spieth turns on the heat

American cards stunning 66 to take two shot lead; Woods one over

Tiger Woods felt the love, but it was Jordan Spieth who heard the roars as he surged to a two-stroke lead in the Masters on Thursday with a scintillating six-under 66.

Woods was back at Augusta National for the first time in three years, finally ready to challenge for a fifth green jacket after spinal fusion surgery last year.

From the practice range to the 18th green, Augusta fans made him more than welcome, although his one-over par 73 gave them few real opportunities to cheer.

"It has been awesome this entire comeback," said Woods, 42. "I got a standing ovation on the range. Coming up to the first tee, the people come out of the clubhouse and the putting green. They're really into it."

The 14-time major winner grabbed his first birdie with a delicate downhill putt at the third. He followed, however, with back-to-back bogeys.

There was more trouble lurking around Amen Corner, where Woods was right off the tee at 11 and his shot from the trees hit a fan and dropped into the rough.

A dip in Rae's Creek at 12 cost him a shot, although he limited the damage with an impressive 18-foot bogey putt.

He pulled strokes back at 14 and 16 and produced two crisp tee shots at 17 and 18 as he capped his round with a pair of solid pars.

Spieth was on fire in round one, stringing together five birdies on the back nine as he seized a two-stroke lead over fellow Americans Matt Kuchar and Tony Finau.

The 24-year-old Texan, who has struggled to find consistency on the greens this season, was even through seven after two birdies and two bogeys.

Spieth rolled in a 14-foot eagle at the eighth, and two-putted from 40-feet for a birdie at 13.

He rolled in a nine-footer at 14, and his pitch at 15 left him a four-footer. Birdie putts from within 10 feet followed at 16 and 17 before a terrific bogey save at 18.

Finau didn't even know if he'd make it to the first tee after suffering a "pretty excruciating" ankle injury celebrating a hole-in-one in the par-three contest on Wednesday.

But once doctors told him he could do no further damage, he was determined to play and was rewarded with a debut Masters round that included six birdies and two bogeys.

Kuchar had five birdies on the back nine to join him on 68.

Northern Ireland's Rory McIlroy, who can complete a career Grand Slam with a first Masters victory, headed a group of seven players on three-under 69.

He was joined by Masters newcomer Li Haotong of China, former British Open champion Henrik Stenson of Sweden, Spain's Rafael Cabrera Bello, Canadian Adam Hadwin and Americans Patrick Reed and Charley Hoffman.

Leading scores (after 18 holes): 66: Jordan Spieth (US); 68: Tony Finau (US), Matt Kuchar (US); 69: Adam Hadwin (Can), Li Haotong (Chn), Henrik Stenson (Swe), Charley Hoffman (US), Patrick Reed (US), Rory McIlroy (NIR), Rafael Cabrera Bello (Esp); 70: Bernd Wiesberger (Aut), Zach Johnson (US), Marc Leishman (Aus), Phil Mickelson (US), Rickie Fowler (US); 71: Vijay Singh (Fij), Satoshi Kodaira (Jpn), Cameron Smith (Aus), Xander Schauffele (US), Louis Oosthuizen (RSA).
