McIlroy surrenders share of US Open lead after shaky start

:Rory McIlroy, seeking an elusive fifth major title, relinquished his share of the overnight lead in early second-round U.S. Open action on Friday in North Carolina where the notoriously tricky Pinehurst No. 2 layout bared its teeth.

McIlroy, who began the day level with Patrick Cantlay after opening with a five-under-par 65 that left them one shot clear of Swede Ludvig Aberg, went out in the fifth group from the 10th tee and covered the back nine in two-over-par 37.

World number three McIlroy, who was one of two players to go bogey-free in an opening round where only 15 players managed to break par, saw that clean streak end quickly on Friday.

He then bogeyed the par-three 15th where he failed to get up and down after his tee shot rolled off the false front that protects an otherwise accessible green.

McIlroy looked certain to slip further back at the par-three 17th after his long-range birdie putt rolled off the green but he managed to save par with a brilliant chip from 39 feet that produced a wild roar from the surrounding fans.

He made par at the 18th and began the homeward nine two shots behind Cantlay.

Belgian Thomas Detry, three under through his first four holes, was a shot off the lead while
