Oakmont - Dustin Johnson powered through two punishing rounds at Oakmont on Friday to seize a share of the lead at the weather-disrupted US Open Golf Championship.
World number six Johnson carded the first bogey-free round of the tournament with a three-under par first-round 67 that put him one shot behind unlikely first-round leader Andrew Landry.
Johnson was among the wave of players who went straight into the second round as organizers fought to get the tournament back on track in the wake of three weather delays that saw only nine players complete the first round on Thursday.
Johnson put on another precise display in the afternoon, firing two birdies and one bogey in a one-under 69 on an Oakmont course already firming up in warm, sunny weather.
"I'm in pretty good shape, so the physical part's no problem," Johnson said of the long day. "But definitely mentally you've got to make sure you stay sharp all day, because you can't go to sleep on any shot out here."
His four-under total of 136 had him atop the leaderboard with Landry, who hit just one shot on Friday but made it count.
Landry was standing over a 10-foot birdie putt at his final hole, the ninth, when play was halted for the day on Thursday.
The 28-year-old Texan, ranked 624th in the world, calmly knocked it in then took the rest of Friday off, and will start his second round on Saturday morning along with approximately half the field, with the full field to then start the third round.
England's Lee Westwood was alone at three-under, with all of his second round to play.
The former world number one finished with back-to-back birdies and three birdies over his final six holes of a round he had jump-started on Thursday by holing out for eagle from the fairway at 14.
Scott Piercy and Spain's Sergio Garcia carded even par second rounds to reach two-under 138, joining Ireland's Shane Lowry who was two-under through 18 holes.
Even as the rain-softened Oakmont greens began to dry and regain some of their bite, American Daniel Summerhays showed birdies were possible, notching seven in a sparkling five-under par 65 for 139, leading a group of seven on one-under.- Day, McIlroy struggle -
World number one Jason Day and third-ranked Rory McIlroy, both touted as title contenders will instead be keeping an eye on the cut line.
McIlroy, the 2011 US Open champion, bogeyed the last three holes of his first round for a seven-over 77 that left him 11 shots off the pace.
He said the stop-start play on Thursday "definitely complicated" the first round.
"But when you shoot 77 everything is a bit complicated," McIlroy added.
World number one Jason Day didn't start the first round until Friday, but once hid did his misery lasted twice as long as McIlroy's.
The Australian's first-round 76 included a double-bogey at the par-four seventh, where he was in two bunkers and needed two attempts to get out of one of them.
He had managed to regain some ground with three birdies and two bogeys leaving him five-over for the tournament with three holes remaining when play ended.
Phil Mickelson's optimism that this could finally be his US Open year -- after six runner-up finishes in the only Grand Slam he has yet to win -- proved unfounded.
Mickelson was seven-over with two to play at the end of the day.
Spieth, aiming to become the first to successfully defend the US Open title since Curtis Strange in 1989 was two-over after one round and bullish on his chances of contending over what will be a busy weekend.
"A couple of tough breaks," Spieth said. "(I'm) still in it."First-round scores at the US Open on Friday at the par-70 Oakmont
