US Open 2012: Round one summary

Tiger Woods shares second place at the 2012 US Open at San Francisco's Olympic Club as only six players break par on the treacherous Lake Course

Westwood, Donald and McIlroy

The first round of the 2012 US Open at San Francisco's Olympic Club threw up some surprises as 156 players battled the brutal Lake Course.

Michael Thompson - who lost the final of the US Amateur on the same course in 2007 - led the field by three shots after round one with a brilliant 66.

Thompson took advantage of the morning conditions to record a score that is unlikely to be beaten this week.

Tiger Woods lies in a tie for second on one-under-par after a wonderful display of patience and course management.

The former world number one - oozing confidence after his recent victory at Memorial - showed exactly how to compete with a US Open course: hit fairways and play conservative golf.

His playing partners - Phil Mickelson and Bubba Watson - struggled, taking 76 and 78 shots respectively. Watson declared after the round he felt 'beat up.'

As the day progressed, the course became firmer and faster and a breeze picked up, making conditions far harder than in the morning.

The marquee afternoon group, comprised of Luke Donald, Rory McIlroy and Lee Westwood, had a nightmare start, managing just three birdies between them.

Westwood fared best, playing the last 13 holes in one-under-par for a respectable 73.

McIlroy stumbled to a 77, and Donald a birdie-free nine-over-par 79. Both players need a decent second round just to make the cut.

It wasn't all doom and gloom in the afternoon, however. Britons Justin Rose and 2010 champion Graeme McDowell both finished with back-to-back birdies to end the day on one-under-par, two of only six players to break 70 on day one.

Nick Watney also shot 69, thanks largely to only the third albatross in US Open history on the par-5 17th.

David Toms also shot 69, and home favourites Matt Kuchar and Jim Furyk returned steady 70s in tough afternoon conditions.

Ian Poulter matched their 70 in a round which included an eagle two at the driveable 7th.
