Paul McGinley holed an eagle at the last to post a record 36-hole total and lead the PGA Championship on day two.

The Irishman added 66 to his overnight 65 to help him to 13 under and better by one the previous best of Ernie Els, Colin Montgomerie and Andrew Oldcorn.

That left him four clear of England's Miles Tunnicliff and Robert Karlsson.

English European Tour rookie Robert Dinwiddie moved from 129th to joint 20th with a superb course record 63, finishing with five straight birdies.

Dinwiddie, who shot 78 in the first round, said: "To hold the Wentworth course record is something special. To putt as well as I did is just tremendous.

"I was hoping maybe for five or six under and make the cut. That was fantastic. I lost track of it at one point, but just kept hitting good shots."

Ernie Els scored 60 around the course, but that was in the World Match Play Championship and not every putt was holed, so did not constitute a course record.

Lee Westwood was forced to pull out with a virus, though, while Montgomerie and Els missed the cut.

Ryder Cup points-leader Westwood lasted just five holes on day two, firing three bogeys, before he withdrew.

An opening 77 on Thursday had left him unlikely to make the halfway cut, and he said: "I had a Chinese meal last night, but I don't think it's something I ate because I've got a sore throat as well. I think it's a virus.

The world number 20, who missed the Wachovia Championship in America earlier this month because of a virus, now has two weeks off before the US Open.

His withdrawal means Luke Donald - at three under - is the only player in the world's top 20 left in the tournament.

That gives McGinley a great chance of victory, with no major winner within 13 shots of him, and the Irishman told BBC Sport: "I've been playing like this most of the year without results.

"The margin is so small between success and not and the difference is putts. If I am going to do well here I'm going to have to continue to putt well over the next two days."

Tunnicliff, who shot a 65, admitted he had treatment on a forearm injury to play, adding: "It's 'beware the injured golfer' again.

"The physios worked very hard and managed to sort me out with some acupuncture."

Meanwhile, Montgomerie was among a number of high-profile players to struggle, the Scot adding a 75 to his first-round 73 to leave him four over, three shots off the cut.

Europe's Ryder Cup captain Nick Faldo said on Tuesday he thought the team's emotional figurehead was still capable of rallying to qualify for the 19-21 September match against the United States.

But, asked on Friday if he was encouraged by Faldo's remarks, Montgomerie replied: "That's the furthest thing from my mind.

Something will click and I'll get my confidence going Justin Rose

The only previous time Montgomerie missed the PGA cut was on his debut in 1989.

South African Els lay alongside Montgomerie, with Justin Rose a shot back.

"Nothing working on the range is translating to the course, but I've just got to keep working hard," said the 27-year-old Englishman.

"This is the game of golf. You've seen it thousands of times that players go through downs and this is a bit of a down for me right now. I've been here before.

"Technically I'm not great... but something will click and I'll get my confidence going. I think I've proved in the past I'm good at coming back."
