Golf - US Open: Mike Weir shot a six under 64 at Bethpage Black to take the clubhouse lead as the rain-delayed first round of the US Open was finally completed this evening. Graeme McDowell, who had held the clubhouse lead for much of the day, is five shots back on one under.

Weir posted eight birdies undone by a double bogey at the par-four sixth hole in his round and is two shots clear of Sweden’s Peter Hanson with former world number one David Duval three shots behind following a 67.

It could have been much better for Weir as he reached the sixth, his 16th of the round, at six under and on course for a US Open record round of 62. The six at the sixth put paid to that but he rallied with a birdie, birdie finish.

Former world number one Duval, who suffered an alarming dip in form following his victory at the 2001 Open Championship at Lytham, had led a charge among the second wave of starters in the 156-man field as they finally got their first rounds under way in drying conditions on still soft greens.

Those conditions helped the late starters at Bethpage Black steal a march on their earlier rivals when American amateur Drew Weaver and McDowell were the only two players under par.

McDowell, coming off a final-round 63 at the St Jude Classic in Memphis last Sunday, posted a one-under-par 69 after opening-round play resumed this morning following yesterday’s wash out on Long Island, while defending champion Tiger Woods suffered a nightmare finish to his first round.

McDowell’s 69 gave him a share of the early clubhouse lead alongside Weaver but with conditions already more benign, the Northern Irishman said he was certainly not getting carried away.

“I’ve led a few majors after day one,” McDowell said. “It’s not really what I’m trying to do. I’m just trying to stick around for the weekend. I’m trying to position myself as well as I possibly can and compete in Sunday afternoon.”

World number two Phil Mickelson, Adam Scott of Australia and Americans Lucas Glover and Ricky Barnes joined McDowell and Weaver at one under having been at three under after 14 holes with those low scores possibly spelling trouble for world number one Woods, who had been at level par with four holes to play but finished his round with a run of double bogey, bogey, par, bogey to leave him with a four-over 74.

Woods said: “I was even par with four to go, and I was right there where I needed to be, and two bad shots and a mud ball later, here we go and I’m at four over par.”

With play washed out after just three-and-a-quarter hours on Thursday, there had been a blanket morning restart after groundstaff worked right up until the players resumed their rounds to get the waterlogged par-70 course up to scratch.

As the morning progressed conditions became more benign and birdies began to creep onto scorecards. That was not, however the case for Woods and reigning Open and US PGA champion Padraig Harrington.

Woods missed an eight-foot par putt at the seventh with his first stroke of the day to fall to two over par while Ireland’s Harrington also made bogey at the hole and then bogeyed the ninth after tangling with the rough off the tee.

Six over became seven at the 12th but the Dubliner sent down back-to-back birdies at 13 and 14 and was back to five over with four holes to play.

Woods also clawed his way back from two over, with birdies at the 11th and 14th to get to level par but then both major champions double-bogeyed the par-four 15th to swing once more into reverse gear.

Woods kept going in the wrong direction but Harrington finished with a birdie at the last having got out of trouble from a fairway bunker with a wedge to 12 feet.

Rory McIlroy had a somewhat mixed bag on his US Open debut and, despite three birdies on the trot, finished on two over while Darren Clarke is four over.
