Graeme Storm is no longer in the lead at the USPGA Championship but it looked like Tiger Woods would be before too long.

Storm, from Hartlepool, entered Friday's second round of the USPGA Championship with a two-shot lead, but a six-over-par 76 has him at one over 141 through 36 holes, four shots off the lead.

After playing in one of the final groups on Thursday, Storm was in the first group off the first tee yesterday.

He spent much of the time in between worried about missing his tee time, but he should have been more concerned with how he would play.

''I didn't get much sleep,'' Storm admitted. ''I went to sleep at 10pm and woke up about 2am and was on and off after that.

''I was worried about missing my alarm call, which I normally don't think about. But, when you're leading a major, it's slightly different.''

Playing in his first USPGA, Storm fired a bogey-free 65 on Thursday but things were certainly different yesterday.

He started with a par but back-to-back bogeys dropped him into a share of the lead with John Daly, who had yet to tee off.

He didn't play a shot from the fairway until his third on the par four third hole. He made two bogeys to fall into a tie with Daly, then came back with a fine approach shot to six feet on the fourth for a birdie that got him to four under.

Another birdie followed on the fifth, but he bogeyed the seventh and ran up a double bogey at the par-three eighth.

He closed his front nine with a birdie to go out in 37 but bogeyed the tenth and 12th and carded his last birdie at the par-five 13th, converting from just inside two feet after missing a long eagle attempt.

Still in red numbers and just a shot off the lead, Storm had a rough finish, bogeying the 15th, 16th and 18th.

''I didn't get the run of the ball that I did yesterday,'' he said. ''I am still in contention but disappointed.

''I didn't play that badly but I was punished when I made a mistake.

"It is disappointing, but I didn't really play that badly. But when I missed a fairway I was punished and it was the same with the greens.

"But it's all part of the learning curve for me and I will take the positives from it. I've gone into the second round of a Major as the leader, which is something to remember.

''It did feel different today. It's a great experience and one I will learn from.

"I hope to have a good weekend because I'm not far away from the leaders. I'll just have to take it on the chin and come back fighting tomorrow.''

Canadian Stephen Ames held the lead at four under after birdies at the 13th and 14th. But he closed with a bogey on 18 and is tied for second at three under after a 69.

Scott Verplank moved to three under and a share of second with Daly after playing his first 15 holes in three under. And he took the lead at four-under 136 after a bogey-free 66 that included four birdies.

Woods kept his mistakes to a minimum early yesterday, carding a birdie at the first and another at the fourth to get to one under for the championship.

The world number one split the fairway on his opening hole and converted from five feet for his first birdie. A three iron down the right side of the fairway at four and an approach to 15 feet led to another birdie and had Tiger on the prowl once again.

Open champion Padraig Harrington slipped with a three-over 73. He started his round with a birdie at ten but followed it up with consecutive bogeys to drop to even-par.

Harrington bogeyed 17 and 18 to finish the front nine and he closed his round with a bogey at nine.

A birdie at the par-three sixth was his only birdie in his last 17 holes.

''I had a disappointing bogey at the last there. I would like to have been one or two better,'' Harrington said. ''I'm not too bad, but I need to play better golf on the weekend."
