A 90-minute delay for fog prior to play getting underway on day one of the US Open at Torrey Pines will result in round one not being completed until Friday morning.

36 players were caught on the golf course when play was brought to a halt for darkness at 7.51pm California time.

When play was halted, all but two of the Australians in the field (Cameron Smith and Matt Jones) had completed their rounds, Adam Scott leading the way at 1 under par and just three from the lead held by Russell Henley and Louis Oosthuizen, Oosthuizen, though, still has two holes to play.

Smith is at even par and has two holes to play but he has found the fairway bunker at the 17th and might struggle to make par and Matt Jones, like Smith, is currently playing his 17th hole at 1 over with a 4 footer for par to negotiate when he returns.

Scott fought back from a slow start to his round after bogeys at his second and third holes had him on the back foot early. He birdied the par 5 9th after a sand save from the green-side bunker and then birdied the 17th from 20 feet.

He found the fairway bunker from the tee at the last but laid up and then converted an eight-footer for birdie to get himself into red figures for the first time. The round of 70 has him well placed ahead of an early morning round on day two.

Smith parred his first 14 holes before a bogey at the 15th but he bounced back immediately with a birdie from 20 feet at the 16th before being forced from the golf course when on the 17th.

Wade Ormsby did well in just his second US Open to be round in 1 over par 72 along with Matt Jones, Brad Kennedy and Marc Leishman are at 3 over after rounds of 74 and Stephen Allan opened with a round of 80.

Leishman bogeyed three of his last four holes after being well enough placed until late in his round, no doubt a huge disappointment given his love affair with the Torrey Pines layout.
