US PGA update: Graeme Storm stole Tiger Woods and John Daly's thunder in the first round of the US PGA Championship.

The Englishman birdied his first two holes, a start which helped propel him into a lead at five-under through 11 holes at steamy Southern Hills.

Storm, playing in his first US PGA Championship, made an immediate impression with birdies at 10 and 11.

He continued his run to the lead with birdies at 13, 16 and the first to take a two-shot advantage. After a fast start, Woods faded while Daly stayed cool under the pressure of a major and the heat in Oklahoma.

At three-under par 67, Daly was the clubhouse leader by one shot over Arron Oberholser, while Woods finished with a one over 71.

Newly crowned Open champion Padraig Harrington, among the later starters, reached the turn in level par while Paul was two-over after six holes.

Darren Clarke appears to have played himself out of the tournament after opening with a seven-over 77. The Tyrone man, who was playing alongside Retief Goosen and Boo Weekley, double bogeyed his first hole, the 10th, and struggled in the intense heat, finishing with another six to leave him languishing well down the field.

Among the early starters, Woods was three-under through six holes and tied for the early lead. He had just one more birdie the rest of the way with five bogeys for a disappointing end to a round that started with such promise.

Daly - only in the field because of his victory at Crooked Stick in 1991 - started steadily before improving.

In the Open at Carnoustie last month, Daly was five-under through 11 holes but finished with three bogeys, a double-bogey and a triple-bogey on the last seven.

He went on to miss the cut and was not considered to be a threat this week — but he looked like one today.

Woods is always a threat to win and, starting his round on the 10th hole, he wasted no time making his presence felt.

A 10-footer for birdie at his opening hole was followed by another at the par-five 13th. Woods then grabbed a share of the lead two holes later with another birdie.

But the man who was chasing a 13th major was unable to maintain his momentum.

He bogeyed 18 to close his front nine and also numbers two and four before a birdie at the par-five fifth got him back to one-under.

Woods was unable to stay in red numbers after consecutive bogeys at seven and eight and said: "I felt like I hit the ball better than my score indicates, which is good.

"That's a good sign heading into the next three days, and I just need to clean up my round a little bit."

Mark Wilson, Camilo Villegas, 2006 US Open champion Geoff Ogilvy, England's Lee Westwood and Austria's Markus Brier finished the first round on one-under 69.

Retief Goosen, who won the US Open here six years ago, was on even-par 70 after a round with two birdies, two bogeys, an eagle and a double-bogey.

Sergio Garcia was as low as three-under but settled for a 70 after a bogeys at the eighth and ninth to close his round.

The Spaniard said: "It's just a shame — the bogeys on the last two. But overall, not a bad round."

Westwood was also flirting with the lead, at one point sharing it with Daly at three-under, but a rough patch late in the round dropped him to a share of ninth.

A bogey at the par-three sixth was followed by a birdie at seven, which tied him with Daly.

However, Westwood coughed up his part of the lead with a double-bogey at the par-three eighth.

He explained: "It was tricky out there and the breeze made it difficult to hit fairways. It's a difficult golf course and you've got to have your wits about you. I didn't really hit a bad shot on the eighth but it's one of the hardest flags on the course.

"I'm not too worried about that. I would have taken anything under par."
