10.20 a.m. Leader through 36 holes, Brandt Snedeker gets underway with Australian Adam Scott.

 Preview: Brandt Snedeker is the surprise leader heading into the weekend at the Open at Royal Lyham and St. Annes. The Nashville native struck a stunning 64 to leave him a shot clear of first-round leader Adam Scott, at 10-under par.

Having missed the cut on his three previous visits to the Open, Snedeker's showing surprised many, including himself.

I'm in shock right now, said the 31-year-old, according to the Open website.

I feel pretty good not to have dropped a shot so far this week and am proud to tie the Championship 36-hole record.

I'm playing what I'd call boring golf right now, he added. All I'm trying to do is to hit the middle of the greens and not get in any trouble.

Although Snedeker has yet to drop a shot so far through 36 holes, those behind will feel that it is only a matter of time before he starts faltering, especially with the tension of leading the historic tournament.

Tiger Woods is ominously placed just four shots back of the lead after a second-consecutive round of 67. The 14-time major winner aided his challenge considerably with two birdies in the final three holes having dropped a shot at 11.

Dane Thorbjorn Olesen sits a shot further back at 5-under, while former major winners Graeme McDowell and Paul Lawrie are among a cluster of five players six shots off the lead.

World No.1 Luke Donald is just about still in contention, too. The Englishman had an eventful round of 68, featuring three bogeys and five birdies to leave him at 2-under for the Championship.

I'm certainly feeling more and more comfortable, Donald said, according to the Associated Press. It's nice to string a couple of solid rounds together in a major. Obviously where I am in my career, I need to be contending. And obviously this was a good solid two rounds. I'm looking forward to the weekend.

One man looking at the weekend with a great deal less zeal is Rory McIlroy. The world No. 2 had a dismal second round that left him at 2-over and only making he cut by two strokes.

It's just tough when you're really trying to get something going and it's just not quite happening, said McIlroy, who continues to fight to rediscover his best form.

At least McIlroy will be sticking around for the weekend. The same cannot be said for Phil Mickelson. The four-time major winner will be heading home after a round of 78, featuring three double bogeys, put him at 11-over.
