Rory McIlroy had a disappointing three bogeys over his first nine holes while American Wyndham Clark jumped to the top of the leaderboard as second round action got underway at the US Open in Los Angeles on Friday.
Starting on the back nine, world number three McIlroy atoned for a bogey on 11 with a long, curling birdie putt on the next to move to three off the lead.
But near misses with the putter, including one on 18 that lipped out, left him two-over par for his round at the turn. Action on the North Course of the Los Angeles Country Club kicked off after Rickie Fowler and Xander Schauffele made record-breaking starts with matching eight-under-par 62s on Thursday and ideal scoring conditions continued on Friday.
Clark had three birdies and no bogeys in his first nine holes to leap ahead of Fowler and Schauffele by a stroke midway through his round.
